Adoption of sustainable development schemes and behaviours in Italy
Authors: Kühtz Silvana
Published: April 2007

Purpose

The purpose of this paper is to investigate issues and concerns associated with sustainable development (SD) in Italy for different stakeholders, with a focus on the role of education. Cognitive maps for 49 individuals living in Italy have been developed and their differences analyzed and discussed with the aim of designing a seminar to foster mental and natural ecology and create awareness for SD ethics and values.

Design/methodology/approach

Cognitive maps are used to delve into the concept of SD in Italy and to investigate what actions are needed to implement it. Respondents were asked separately to talk about their idea of SD.

Findings

The 49 interviews showed that all the actors consider fundamental the role of education, culture and way of thinking for the implementation of SD. An appropriate seminar has been designed as an educational process that completes the formal knowledge provided at school.

Practical implications

Actions for future actions are indicated, i.e. to undertake the designed seminar in a local community in Italy as a pilot study and to promote it to administrations, companies, and groups.

Originality/value

The majority of the interviews express an explicit sense of resignation and cynicism as regards SD in action, but 41 out of 49 when showed the designed seminar declared the intention to attend it. This paper fulfils the need to have practical tools to reframe the way we think about the world and SD and act for it. Also, it gives a look at the concerns associated to SD and barriers to action in Italy.
Effects of working capital management on SME profitability
Authors: Juan García‐Teruel Pedro , Martínez‐Solano Pedro
Published: April 2007

Purpose

The object of the research presented in this paper is to provide empirical evidence on the effects of working capital management on the profitability of a sample of small and medium‐sized Spanish firms.

Design/methodology/approach

The authors have collected a panel of 8,872 small to medium‐sized enterprises (SMEs) covering the period 1996‐2002. The authors tested the effects of working capital management on SME profitability using the panel data methodology.

Findings

The results, which are robust to the presence of endogeneity, demonstrate that managers can create value by reducing their inventories and the number of days for which their accounts are outstanding. Moreover, shortening the cash conversion cycle also improves the firm's profitability.

Originality/value

This work contributes to the literature in two ways. First, no previous such evidence exists for the case of SMEs. Second, unlike previous studies, in the current work robust test have been conducted for the possible presence of endogeneity problems. The aim is to ensure that the relationships found in the analysis carried out are due to the effects of the cash conversion cycle on corporate profitability and not vice versa.
Global valuation of equity: one market correcting another
Authors: Madura Jeff , Richie Nivine
Published: April 2007

Purpose

The purpose of this article is to assess the pricing of stocks that are traded on both a US stock exchange and a non‐US stock exchange to determine whether interaction exists between the two exchanges.

Design/methodology/approach

This article identifies extreme price movements of stocks (winners and losers) in the non‐US stock exchanges that also trade as American depository receipts (ADRs) in the US market, and measure the US market response. Also identifies extreme price movements of stocks (winners and losers) in the US stock exchanges that also trade in the non‐US markets, and measure the non‐US market response.

Findings

Finds a significant reversal of winners and losers in the US market, which suggests that the US market attempts to correct the pricing in non‐US markets. Also finds that extreme ADR price movements in the US markets are followed by corrections in the non‐US market.

Research limitations/implications

Market participants appear to monitor unusual stock price movements that just occurred in other markets, and correct for unusual price movements that cannot be rationalized. Such activity in global markets expedites the process by which price discrepancies are corrected. The evidence also suggests that the cost of equity in one market can be influenced by the actions of investors in another market.

Originality/value

This study of non‐US stocks that are cross‐listed in the US in the form of ADRs allows us to examine the interaction of pricing in a stock's local market with pricing in the US market.
Energy sector management issues: an overview
Authors: Bhattacharyya Subhes C.
Published: April 2007

Purpose

The objective of the paper is to put the energy sector challenges in perspective and to provide a general understanding of sector management issues.

Design/methodology/approach

The paper follows an analytic‐deductive method to analyse the issues using existing literature as the source of information. Starting with an analysis of the evolution of the sector, the paper identifies various present and future challenges facing the sector and indicates the management issues that could emerge.

Findings

As future developments are shaped by the past and present, it is important to identify and understand the drivers that could bring profound changes. The dynamic nature of the sector brings new challenges and a better understanding of the present issues could help prepare for the future.

Research limitations/implications

The paper focuses on the broad, generic coverage of the issues and is not intended to provide country specific or industry specific issues and challenges.

Originality/value

The paper presents the multi‐dimensional interactions of the energy sector and offers an analysis of the multitude of sector management issues.
Sino‐Indian cooperation in the search for overseas petroleum resources
Authors: Nandakumar J.
Published: April 2007

Purpose

In the past few years Indian companies witnessed competition from their Chinese counterparts in acquiring overseas petroleum resources. In an attempt to avoid competition with each other the two governments have taken various measures, which finally led to the two countries signing a Memorandum of Understanding for energy cooperation especially for joint overseas bidding for exploration and production. Although the Indian side perceives the cooperation effort as a major breakthrough in avoiding Chinese competition in the overseas energy arena, it appears to be of limited prospects to India in terms of acquiring overseas petroleum assets or exploration and production contracts. The purpose of this paper is to examine the prospects and implication for India in the overseas energy cooperation with China.

Design/methodology/approach

The paper analyses the strategy which China is pursuing, in order to maximise its gains and outmanoeuvre India in the overseas energy asset biddings.

Findings

The main findings of the paper show that competition would be the prevailing factor in their interaction in overseas energy search.

Research limitations/implications

While there are many potential areas of cooperation between India and China, this paper focuses only on their cooperation to jointly procure energy fields in order to evaluate the likely prospects and implications for India.

Originality/value

This paper is original work based on facts and information regarding energy cooperation between India and China. The paper offers an analysis of India‐China interaction in the overseas energy arena, and the prospects and implications of cooperation to India.
An account of the experiences of 51 families involved in an initial child protection conference
Authors: Bell Margaret
Published: April 2007

This paper reports on one part of a research project, funded by the Nuffield Foundation, to evaluate the effects of involving parents in 83 initial child protection conferences in a northern city between May 1991 and June 1992. The experiences of two groups of families are recounted and compared, those who attended the conferences and those who did not An analysis was made of the degree to which the parent's participation in the conference affected their overall attitude to the intervention. There were differences between the two groups with regard to their feeling fairly treated, and in their relationship with their social worker. The factors most strongly associated with attitude were whether the child had been removed from the family or statutory action was recommended, and whether the parents agreed abuse had taken place. The fear of removal of the child had an independent influence on the overall attitude, irrespective of whether or not the parents attended the conference. The parents who attended were glad they had gone but found the experience emotionally difficult Although their positive feelings of involvement did not extend to a conviction that they had influenced the decisions, their on‐going relationship with their social worker was less likely to have been impaired where they had been invited and attended.
Parental competence and the welfare of the child: issues for those who work with parents with learning difficulties and their children. A response to Booth and Booth
Authors: Schofield Gillian
Published: April 2007

The parental competence of parents with learning difficulties is discussed by Booth and Booth as if it was separable from consideration of the welfare of their children. The author responds by arguing that The Children Act 1989 requires a focus on the welfare of the child and any debate about parenting must take this into account. The Act also imposes a statutory duty on local authorities to promote the upbringing of children by their families. If parents with learning difficulties need help to carry out some of their parental responsibilities, they have the right to expect services which are sensitive to their needs. Their children, however, must also have rights to help, care and protection where this is needed, as other children have. The author argues for an integrated approach to work with parents with learning difficulties and their children, in which the welfare of the children is seen as the proper concern of all parties.
Children whose parents misuse alcohol: a study of services and needs
Authors: Hill Malcolm , Laybourn Ann , Brown Jane
Published: April 2007

Despite the fact that many children are affected by parental alcohol misuse, both services and research have largely concentrated on adults. Recently, projects have been set up to assist children, but developments have been piecemeal. This article reports on a qualitative study which learned directly from children, their parents and some young adults what they saw as the effects on children of excessive drinking by one or both parents. The most common consequences were distress at witnessing violence to the other parent or to the home; verbal abuse towards the children; feelings of shame; and taking on caring and protective roles. However, the children were not passive victims and usually took active steps to tackle the drinking or modify its impact Those in the sample usually had at least one family member who helped them and was trusted. Nevertheless, many wished they could meet with others in the same position, so they could feel less isolated and learn from each other. The need was identified for access to a network of services with group work, individual counselling, family mediation and educational components.
Analysis of paranasal sinus development and anatomical variations: a CT genetic study in twins
Authors: Chaiyasate S. , Baron I. , Clement P.
Published: April 2007

Objective:  To determine if anatomical variations in the paranasal sinuses of twins are the result of genetic or environmental influences.

Study design:  A prospective, observational study.

Setting:  An academic hospital in Brussels, Belgium.

Participants:  Twenty‐five volunteer twins (17 identical twins and eight non‐identical twins). Of the identical twins, six were both female and 11 both male. The mean age was 40.6 years (18–49). Of the non‐identical twins, one pair was female and seven were male. The mean age was 39.6 years (25–48).

Main outcome measures:  The CT‐scan similarity in anatomical structures (frontal cells, agger nasi cells, concha bullosa, infraorbital cells and changes in the shape of the lamina orbitalis), and the intranasal and paranasal sinus morphology was compared between the twins.

Results:  Among the studied variables, there was no statistically significant difference between the two twin groups (Fisher's exact test, P > 0.05). Regarding combine‐studied parameters, there were no identical CT scans in the twins. However, a tendency of non‐genetic influence existed in the development of frontal cell type III and IV, and infraorbital cells, as well as a liability of genetic influence in the presence of concha bullosa.

Conclusion:  In this study, the differences in anatomical structure of the paranasal sinuses between identical and non‐identical twin pairs were not statistically significant. This indicates that environmental factors are more significant than genetic ones in the development of anatomical variations in paranasal sinus anatomy.
Education qualification levels and school careers of unilateral versus bilateral hearing aid users
Authors: Beijen J. , Mylanus E.A.M. , Snik A.F.M.
Published: April 2007

Objective:  Analyse the difference in school careers and secondary school qualification levels between unilateral hearing aid users and bilateral hearing aid users.

Study design:  Retrospective questionnaire study.

Setting:  Postal‐based questionnaire.

Participants:  Names of adults known to have been fitted with unilateral or bilateral hearing aids during childhood were retrieved. This resulted in 292 names. Participants were selected using the following criteria: availability of the medical record, presence of bilateral hearing loss, completed secondary school education, normal IQ and a minimum aided word‐recognition score of 70% at 10 years of age. The questionnaire was sent to 50 potential participants of whom 40 responded, resulting in two groups comprising 19 unilateral and 21 bilateral hearing aid users.

Methods:  A questionnaire was developed to obtain data on secondary school levels and aspects of the school careers, such as type of schools attended (mainstream versus special), repeating a school year and additional assistance (speech and language therapy, personal frequency modulation systems).

Main outcome measures:  Comparison of the benefit of bilateral hearing aid fitting versus unilateral hearing aid fitting on secondary school qualification level, type of school the children attended, class failure and additional assistance used.

Results:  The group of bilaterally fitted hearing aid users eventually completed secondary school at a superior level than the unilaterally fitted users. 33% of binaural hearing aid users achieved qualifications giving access to a bachelors degree compared with 21% of unilateral users. There were no differences between those fitted with unilateral and bilateral hearing aids in the type of schools attended, repeating a school year and additional assistance.

Conclusions:  The bilateral hearing aid users obtained superior secondary school qualifications than the unilateral users but their school careers were comparable.
Quinsy treated by aspiration: the volume of pus at initial aspiration is an accurate predictor of the need for subsequent re‐aspiration
Authors: Viljoen M. , Loock J.W.
Published: April 2007

Objective:  The aim of this study was to determine an accurate indicator of the need for second aspiration of peritonsillar abscesses the day after initial aspiration.

Setting:  A tertiary otolaryngology care centre.

Participants:  Fifty patients aged between 11 and 49 years with suspected peritonsillar abscess.

Study design:  A prospective case series.

Outcome measures:  The potential indicators investigated included volume of pus at initial aspiration and clinical indicators suggesting persistent pus (dysphagia, odynophagia and trismus). The outcome measure was the presence of pus at subsequent aspiration.

Results:  A linear correlation was found between volume of first aspirate and presence of pus on re‐aspiration (r = 0.9753). A volume of pus <3 mL on initial aspiration accurately predicted <0.5 mL pus on re‐aspiration. Sixty‐four per cent (32) patients had 3 mL or more pus on initial aspiration and in all there was at least 1 mL or more pus on second aspiration. Clinical indicators correlated less well, with a average coefficient on first aspiration of 0.62 and on second aspiration of 0.35.

Conclusion:  The volume of pus on initial aspiration is a very reliable indicator in assessing the need for re‐aspiration of peritonsillar abscesses. If 3 mL or more of pus are aspirated on the first occasion these patients should be seen the next day and have a further aspiration. Clinical symptoms and signs are not useful indicators.
Impact of hydrology on free‐living and particle‐associated microorganisms in a river floodplain system (Danube, Austria)
Authors: LUEF BIRGIT , ASPETSBERGER FANNI , HEIN THOMAS , HUBER FLORIAN , PEDUZZI PETER
Published: April 2007

1. A floodplain segment of the Danube River downstream of Vienna was studied during the hydrologically most dynamic phase (spring–summer) to evaluate the significance of connection between the main channel and the floodplain segment for particle abundance and quality as well as for bacterial and viral parameters, both free‐living and attached to particles.

2. Hydrological connectivity between the main channel and its floodplain segment (expressed as water age) influenced particle abundance and quality. Polysaccharide‐containing particles [Alcian positive‐stained particles (ASP)] and protein‐containing particles [Coomassie positive‐stained particles (CSP)] each contributed a substantial fraction to total suspended solids and were both positively related to water age. ASP were about twice as abundant as CSP.

3. Water age influenced bacterial and viral abundance and the bacterioplankton productivity in the surrounding water. Free‐living bacterial abundance and their bacterial secondary production (BSP) increased continuously with water age, best described by a linear regression. Water age also significantly impacted BSP and per cell BSP of bacteria attached to particles. The abundance of attached bacteria and viruses was not influenced by water age.

4. Bacteria and viruses on particles were influenced by particle quality. Their abundance on particles was closely related to particle size. Particle‐attached bacteria accounted on average for 30.34% (± 3.09) of the total bacterial abundance. A variable and occasionally significant proportion of viruses, between 0.43% and 35.06%, were associated with particulate material.

5. Bacteria attached to particles were significantly more productive than their free‐living counterparts. Their per‐cell activity was on average 8.6 times higher than that of the free‐living fraction.

6. Hydrological connectivity between the Danube River and its floodplain is crucial not only for the exchange of water, sediment and nutrients, but also for microbiota, thus influencing microbial life, distribution and activity.
Effects of glucagon‐like peptide‐1 and sympathetic stimulation on gastric accommodation in humans1

Published: April 2007

Abstract   In humans, glucagon‐like peptide‐1 (GLP‐1) delays gastric emptying by inhibiting vagal activity and also increases gastric volumes, by unclear mechanisms. Because GLP‐1 inhibits intestinal motility by stimulating the sympathetic nervous system in rats, we assessed the effects of a GLP‐1 agonist and yohimbine, an α2‐adrenergic antagonist, on gastric volumes in humans. In this double‐blind study, 32 healthy volunteers were randomized to placebo, a GLP‐1 agonist, yohimbine or GLP‐1 and yohimbine. Gastric volumes (fasting predrug and postdrug, and postprandial postdrug) were measured by 99mTc single photon emission computed tomography imaging. Plasma catecholamines and haemodynamic parameters were assessed. Compared with placebo, GLP‐1 increased (P = 0.03) but yohimbine did not affect fasting gastric volume. However, GLP‐1 plus yohimbine increased (P < 0.001) postprandial gastric accommodation vs placebo and vs GLP‐1 alone [postprandial volume change = 542 ± 29 mL (mean ± SEM, placebo), 605 ± 31 mL (GLP‐1), 652 ± 54 mL (yohimbine) and 810 ± 37 mL (GLP‐1 and yohimbine)]. Plasma noradrenaline and dihydroxyphenylglycol concentrations were higher for yohimbine vs placebo and for GLP‐1 and yohimbine vs GLP‐1. Yohimbine stimulates central sympathetic activity and in combination with GLP‐1, augments postprandial accommodation in humans.
Ground‐penetrating radar as a tool to detect rock heterogeneities (channels, cemented layers and fractures) in the Luxembourg Sandstone Formation (Grand‐Duchy of Luxembourg)
Authors: VAN DEN BRIL KOEN , GREGOIRE COLETTE , SWENNEN RUDY , LAMBOT SEBASTIEN
Published: April 2007

A combined study of radar profiles and thin section analysis supported by modelling of synthetic radar traces reveals that ground‐penetrating radar (GPR) reflections generated in diagenetically altered sandstones cannot always be interpreted unequivocally. This is illustrated in the Luxembourg Sandstone Formation, which has been altered diagenetically by selective carbonate cementation and fracturing. Cemented lenses and concretions developed along the bedding planes, especially at places with high primary carbonate content. Cementation resulted in the alternation of cemented carbonate‐rich sandy layers (thickness 30–50 cm and variable length) and uncemented carbonate‐poor sandstone layers. The ability of GPR to detect the geometry of these lenses and vertical fractures with centimetre apertures has been tested at several antenna frequencies (100, 200, 250 and 500 MHz). Relative dielectric permittivity calculations were carried out to assess variations of this electric property within the cemented and uncemented layers as a function of porosity, calcite and water content in the pores. Two‐dimensional full waveform modelling was also carried out to study the effect of conductivity in the sandstones and the effect of interlayer clay seams. At the penetration depth of the radar (7 m with 250 MHz), cemented lenses and concretions could only be detected with GPR when the porosity contrast was sufficiently high, which is not always the case. This conclusion is supported by the modelling. The data also proved the ability of radar to detect large open vertical fractures along which sandstones are weathered. The study has implications for investigations which will use GPR to detect three‐dimensional distribution of diagenetic pore filling precipitates as well as secondary porosity development along fractures.
Female crickets trade offspring viability for fecundity
Authors: SIMMONS L. W. , GARCÍA‐GONZÁLEZ F.
Published: April 2007

A growing number of studies are suggesting that females can improve the viability of their embryos by mating with multiple males. However, the reason why females should have low rates of embryo viability is puzzling. Here we conduct a quantitative genetic study of maternal effects on embryo viability in the field cricket Teleogryllus oceanicus. After controlling for female body size, we find significant additive genetic variance for ovary weight, a measure of fecundity, and egg hatching success, a measure of embryo viability. Moreover, we show a genetic trade‐off between these traits that is predicted from life‐history theory. High rates of embryo mortality in this highly fecund species might therefore be explained by selection favouring an optimum balance between fecundity and embryo viability that maximizes maternal fitness. Paternal effects on female fecundity and embryo viability are often seen as benefits driving the evolution of polyandrous behaviour. However, we raise the alternative possibility that paternal effects might shift females from their naturally selected optimum, and present some support for the notion that sexual conflict over a female's optimal fecundity and embryo viability might generate antagonistic coevolution between the sexes.
The relative role of male vs. female mate choice in maintaining assortative pairing among discrete colour morphs
Authors: PRYKE S. R. , GRIFFITH S. C.
Published: April 2007

Mate choice has important evolutionary consequences because it influences assortative mating and the level of genetic variation maintained within populations. In species with genetically determined polymorphisms, nonrandom mate choice may affect the evolutionary stability and maintenance (or loss) of alternative phenotypes. We examined the mating pattern in the colour polymorphic Gouldian finch (Erythrura gouldiae), and the role of mate choice, both female and male, in maintaining the three discrete head colours (black, red and yellow). In both large captive and wild populations, Gouldian finches paired assortatively with respect to head colour. In mate choice trials, females showed a strong preference for mates with the most elaborate sexually dimorphic traits (i.e. more chromatic UV/blue plumage and longer pin‐tail feathers), but did not discriminate assortatively. Unexpectedly, however, males were particularly choosy, associating and pairing only with females of their own morph‐type. Although female mate choice is generally invoked as the major selective force maintaining conspicuous male colouration in sexually dichromatic species, and is typically thought to drive nonrandom mating, these findings suggest that mutual mate choice and male mate choice in particular, are an important yet neglected component of selection.

THE SYSTEMATIC POSITION OF THE IPSVICIIDAE (UPPER TRIASSIC HEMIPTERA) AND SOME NEW UPPER PERMIAN AND MIDDLE TRIASSIC HEMIPTERA FROM AUSTRALIA (INSECTA)
Authors: Evans J. W.
Published: April 2007

The Ipsviciidae are a family of Hemiptera, which, up to the present, have been recorded only from Upper Triassic strata in Queensland. The venation of their tegmina is anomalous and has proved difficult to interpret. Consequently, their relationships with other groups of Hemiptera have been uncertain. In a recent publication, China has suggested that the Ipsviciidae are related to an extant family of primitive Homoptera, the Peloridiidae (China 1962). This suggestion is examined, but not accepted. Instead, evidence is given to show that, more probably, the Ipsviciidae belonged to the superfamily Cercopoidea. The affinities of the family Stenoviciidae are discussed and some new Hemiptera of unusual interest described from Australian Upper Permian and Middle Triassic strata.

THE PROBLEMS OF BITING MIDGES (DIPTERA: CERATOPOGONIDAE) IN QUEENSLAND
Authors: REYE ERIC J.
Published: April 2007

Queensland's geographical position gives a midge fauna active in all seasons, containing numerous species suspected or known to feed on birds and mammals. Taxonomy is incomplete but allows a start on the problems midges present both as pests of man, retarding settlement and tourist industry, and as vectors of disease, especially their potential as vectors of the blue‐tongue virus in sheep and of African horsesickness. More knowledge of midge taxonomy and biology is needed to solve these problems. Known Queensland species of Culicoides, Lasiohelea, Leptoconops and Styloconops are listed.

THE INFLUENCE OF FOOD ON LONGEVITY AND OVIPOSITION IN RHYSSA PERSUASORIA (L.) (HYMENOPTERA: ICHNEUMONIDAE)
Authors: Hocking Helen
Published: April 2007

A study was made of the effect of carbohydrate food on the longevity and oviposition of Rhyssa persuasoria (L.). The adult life span was 9 days without food and approximately 45–55 days on a carbohydrate diet. When females were starved, searching and egg‐laying activity were reduced. Aphid honeydew was found to be as effective as honey solution in promoting longevity and oviposition. Some aspects of the availability of honeydew in Australian pine plantations and its importance in the establishment of rhyssines are discussed.
EVALUATING NEW PROSPECTS IN PEST CONTROL
Authors: Geier P. W. , Hillman T. J. , Wilson A. G. L.
Published: April 2007

Advances in biology are contributing increasingly to the progress of insect pest control. The trend is characterized, in particular, by the systematic quest for procedures which involve smaller inputs of chemical and physical energy by man to achieve stated objectives in practical control. The recognition, selection, and exploitation of biological circumstances susceptible of procuring means to influence optimally the demography of noxious organisms calls for an ecologically‐based approach to pest problems, of the kind outlined and discussed here. Simple models are derived to illustrate the method in concept and application.
AUTOGENY IN CULICOIDES WARINGI LEE AND REYE AND CULICOIDES MACKERRASI LEE AND REYE (DIPTERA: CERATOPOGONIDAE) FROM AUSTRALIA WITH NOTES ON BREEDING PLACES AND BEHAVIOUR
Authors: Dyce A. L. , Murray M. D.
Published: April 2007

Culicoides waringi is autogenous for the first batch of eggs and it is probable that the species has completely lost the necessity to feed on blood. Larvae were hatched from eggs deposited by laboratory reared females caged with males and with access only to carbohydrate foods. C. mackerrasi is known to attack man and the development of follicles to Stage V by unfed, unmated females shows the species can be autogenous for the first egg mass.

Notes on the field biology, the behaviour and the distribution of both species are included. The advantages of autogeny for survival of the two species are discussed.
REASSESSMENT OF THE AFFINITIES OF THE GRASSHOPPER TRIGONIZA SULCATA TEPPER, FROM AN EXAMINATION OF THE HOLOTYPE (ORTHOPTERA: ACRIDOIDEA)
Authors: Key K. H. L.
Published: April 2007

Examination of the holotype shows that the grasshopper Trigoniza sulcata Tepper is not a member of the pyrgomorphid genus Monistria Stål, but belongs with a group of genera including Raniliella Sjöst. and Phanerocerus Sauss. currently referred to the acridid subfamily Catantopinae. However, the generic name Trigoniza, as a result of designation of T. maculata Tepper as its type species, is confirmed as a junior synonym of Monistria.

A POSSIBLE ROLE FOR ALIESTERASE ENZYMES IN INSECTS
Authors: Wan T. K. , Hooper G. H. S.
Published: April 2007

The level of aliesterase enzymes in Musca domestica L. was found to be higher in females than males, higher in mated flies of both sexes than in unmated flies and to show a cyclic activity with age in mated flies. Tri‐o‐cresyl phosphate inhibited the aliesterase by approximately 68 per cent. for eight days at a dosage of 90 μg/fly. Increasing dosages of this phosphate did not further inhibit the enzyme nor further reduce the batch of eggs (approximately 40 per cent. reduction) but did progressively increase the pre‐ovipositional period. A possible role for aliesterase enzyme in oögenesis is discussed.
HYDROGEN CYANIDE IN THE DEFENSIVE SECRETIONS OF LARVAL PAROPSINI (COLEOPTERA: CHRYSOMELIDAE)
Authors: Moore B. P.
Published: April 2007

Hydrogen cyanide, benzaldehyde and glucose have been identified as components of the larval defensive secretion in three species of leaf beetles, belonging to the genera Paropsis and Chrysophtharta. These substances, which at some stage may have been combined in the form of a glycoside, are apparently synthesized by the insects, rather than derived directly from the food plant.
ON THE RELATIONSHIPS OF THE CALOPSOCIDAE (PSOCOPTERA)
Authors: Smithers C. N.
Published: April 2007

This paper describes Calopsocus guttatus sp. n. from Queensland and discusses the systematic position of the family, the conclusion being that the Calopsocidae are closely related to the Pseudocaeciliidae and not to the Caeciliidae as indicated in the currently accepted classification. The genus Calopsocus Hagen has been known from three species; the fourth, C. guttatus, is the first from Australia.

Authors: Browne L. Barton , Hoo C. F. Soo , Gerwen A. C. M. Van , Sherwell I. R.
Published: April 2007

Field observations were made on the mating and oviposition behaviour of the hepialid moths, Oncopera alboguttata, O. rufobrunnea and O. tindalei. The three species, which are pasture pests in the New England district of New South Wales, have superficially similar behaviour patterns but a number of differences were observed. In particular, the behaviour of O. alboguttata differs from that of the other two species in several respects. The behaviour patterns of the three species are compared with those of O. intricata and O. fasciculata which have been studied by other workers.
THE CHROMOSOMES OF TWO SPECIES OF THE GENUS AUSTRALOTETTIX RICHARDS (GRYLLACRIDOIDEA: MACROPATHINAE)
Authors: Mesa Alejo
Published: April 2007

i

The chromosomes of Australotettix montanus Richards and A. carraiensis Richards have been studied. Both species share the following characteristics: the chromosome number is 2n=45 ♂‐46 ♀ the sex mechanism is of the XO ♂‐XX ♀ type with the X submetacentric; the X chromosome as well as two bivalents (H1 and H2) are heterochromatic during first prophase.

The species differ in: (a) the pattern of distribution of heterochromatic blocks in H1; (b) the H1 pair consists of two metacentric autosomes in A. carraiensis while these chromosomes are acrocentric in A. montanus; (c) a medium‐sized pair of autosomes is formed by subacrocentric elements in A. carraiensis while they are acrocentric in A. montanus.

The karyotypes of both species do not differ basically from that which is typical for the Macropathinae.
