ANAGYRUS SACCHARICOLA TIMBERLAKE (HYMENOPTERA: ENCYRTIDAE) AND OTHER BIOTA ASSOCIATED WITH SACCHARICOCCUS SACCHARI (COCKERELL) (HOMOPTERA: PSEUDOCOCCIDAE) IN AUSTRALIA
Authors: Carver Mary , Inkerman P. A. , Ashbolt N. J.
Published: April 2007

The encyrtid parasite Anagyrus saccharicola Timberlake was introduced into Australia from Hawaii in 1953 as a biological control agent of Saccharicoccus sacchari (Cockerell), the pink sugarcane mealybug, but was believed not to have become established. However, a recent survey has shown it to be widespread in the principal sugarcane growing areas of Queensland and New South Wales. Other natural enemies of S. sacchari include the fungus Aspergillus parasiticus Spear and the insect predators, Cacoxenus perspicax (Knab), Coccodiplosis sp., Cryptolaemus montrouzieri Mulsant and Oplobates woodwardi Gross. S. sacchari was attended by the ants Paratrechina probably vaga (Forel), P. prob. bourbonica (Forel), Camponotus prob. chloroticus Emery, Tetramorium bicarinatum (Nylander), Pheidole megacephala (F.) and Iridomyrmex sp.
DISTINCTIVE MOTORY BEHAVIOUR IN SOME ADULT PSYLLIDS (HOMOPTERA: PSYLLOIDEA)
Authors: Carver Mary
Published: April 2007

Adults of both sexes of observed psyllids in the genera Anoeconeossa Taylor, Blastopsylla Taylor, Australopsylla Tuthill and Taylor, Glycaspis Taylor and Ctenarytaina Ferris and Klyver walk and stand on the basal tarsomeres, carrying the apical tarsomeres aloft. For most of the time that the species of the first 4 genera are stationary, some or all of their apical tarsomeres oscillate rapidly; those of Ctenarytaina vibrate rather than oscillate. The apical tarsomeres of adult Protyora Kieffer and Schedotrioza Tuthill and Taylor are usually grounded and oscillate weakly and rarely, whereas those of Acizzia Heslop‐Harrison are grounded and do not oscillate. The habit is best developed in lerp‐inhabiting Spondyliaspididae and could be a means of substrate‐borne vibrational communication. Adult Glycaspis walk on the fore and mid legs only, usually dragging the hind legs.
HOST‐ATTRACTION STUDIES OF CULEX ANNULIROSTRIS SKUSE (DIPTERA: CULICIDAE) NEAR ECHUCA, IN THE MURRAY VALLEY OF VICTORIA
Authors: Russell Richard C.
Published: April 2007

The attraction to hosts of a population of Culex annulirostris in a state forest near Echuca, Victoria, was investigated using chicken, guinea pig, dry ice and human bait collections. Chicken bait attracted more females than guinea pig bait in both early and late summer; proportions parous of the different bait samples were similar. Dry ice bait attracted samples with similar proportions parous to human bait. Human bait collections revealed an early evening and a smaller morning peak of biting activity. There was an indication that nulliparous females fed earlier than older females.
A NEST SHARED BY THE SOLITARY WASPS, CERCERIS ANTIPODES SMITH AND C. AUSTRALIS SAUSSURE (HYMENOPTERA: SPHECIDAE)
Authors: McCorquodale D. B. , Thomson C. E.
Published: April 2007

Abstract

Interspecific nest sharing between 2 species of sphecid wasps is recorded for the first time. A nest of Cerceris antipodes Smith appeared to have been joined by a female of C. australis Saussure. The nest contained 2 cells with a mixture of prey of both species, 26 older cells with C. antipodes prey and 6 younger cells with C. australis prey.
EVIDENCE FOR BIOLOGICAL ACTIVITY OF TWO FURTHER ALCOHOLS IN THE SEX PHEROMONE OF FEMALE CYDIA POMONELLA (L.) (LEPIDOPTERA: TORTRICIDAE)

Published: April 2007

Abstract

The behaviour in laboratory bioassays of male codling moth, Cydia pomonella (L.), when presented with various mixtures of (E, E)‐8, 10‐dodecadienol and the 2 saturated alcohols, dodecanol and tetradeconol, shows that the presence of all 3 compounds is necessary in order to obtain a response equivalent to that elicited by the natural pheromone.

Chromosome numbers of 2n = 2,9,10,18,19,20,21,22,23,24,25,26,27,30,31 and 32 were found for Myrmecia pilosula (F. Smith). Karyotopic and morphological evidence indicates the presence of a “M. pilosula” complex with at least 3 biological species.
THE IMMATURE AND ADULT STAGES OF CALLOCOCCUS LEPTOSPERMI (MASKELL) (HOMOPTERA: COCCOIDEA: ASTEROLECANIIDAE), WITH OBSERVATIONS ON LIFE HISTORY
Authors: Coles R. B. , Verberne F. , Brookes H. M.
Published: April 2007

Abstract

The gall‐forming scale insect Callococcus leptospermi was studied in the field to determine its life history and method of distribution on the host plant, Leptospermum sp., previously L. juniperinum (Sm.) Domin (prickly tea tree, Myrtaceae). This paper complements earlier taxonomic studies on C. leptospermi. Until now the adult female has provided most of the available data on the species. Newly described stages include the second instar male, the third instar assumed female and the adult male. The sexually dimorphic first instar and adult female are redescribed. Callococcus leptospermi is ovoviviparous. It is dispersed by migration of second instar larvae from the parent gall to new feeding sites.

IMMATURE STAGES AND LIFE HISTORY OF CHRYSONOTOMYIA SP. C (HYMENOPTERA: EULOPHIDAE), A PARASITOID OF THE JARRAH LEAFMINER
Authors: Mazanec Z.
Published: April 2007

The immature stages and biology of the univoltine Chrysonotomyia sp. C, a primary, larval endoparasitoid of feeding larvae of the jarrah leafminer, Perthida glyphopa Common, are described. Slow development of hydropic eggs and prolonged feeding of the parasitoid larvae enable the host to complete feeding and commence aestivation in the soil. The parasitoids then mature, destroy the host and aestivate until emergence between April and June.

EMERGENCE, HOST‐FINDING AND LONGEVITY OF ADULT HAEMATOBIA IRRITANS EXIGUA DE MEIJERE (DIPTERA: MUSCIDAE)
Authors: Macqueen A. , Doube B. M.
Published: April 2007

Patterns of emergence and of host location by adults of the buffalo fly were examined under ambient conditions. Most buffalo flies (90%) developing from eggs laid at the same time emerged from puparia between 1200–2000 h daly over 4 days; 88% of the total adult emergence appeared on days 2 and 3. The sex ratio of the total emergence was 1:1, but more females than males emerged on day 1.

Of the male and newly emerged female flies which found an isolated cow in the field, most (90%) arrived from 1600–0800 h. The majority of females collected at the cow were nulliparous (61%) and most of these (86%) were newly emerged. Males and newly emerged females showed similar diel arrival patterns, but older female flies showed no pattern.

The longevity of flies that were either netted from cattle, newly emerged from puparia, or netted from dung following oviposition was measured in the laboratory at 27 ± 1.5°C in the absence of a host. Flies held at 60–70% RH and given water lived twice as long as those without water. Flies lived longer at 90–93% RH but provision of water did not increase their survival.
A NEW AUSTRALIAN SPECIES OF COMMUNAL GROUND NESTING WASP, IN THE GENUS SPILOMENA SHUCKARD (HYMENOPTERA: SPHECIDAE: PEMPHREDONINAE)
Authors: McCorquodale D. B. , Naumann I. D.
Published: April 2007

Spilomena subterranea sp. n. is described from southeastern Australia and is the first species of Spilomena Shuckard known to nest communally in the ground. Nests were in sandy soil and were usually occupied by 2–4 females and 0–2 males, but the level of social behaviour is unknown. Adult S. subterranea prey on Psyllidae (adults, nymphs) and Eulophidae (adults). Morphological specialisations for ground nesting are described for S. subterranea and related species.
CONTRIBUTION OF THE FEMALE PARENT TO SURVIVAL OF LABORATORY‐REARED OFFSPRING IN THE DUNG BEETLE KHEPER NIGROAENEUS (BOHEMAN) (COLEOPTERA: SCARABAEIDAE)
Authors: Edwards Penelope B.
Published: April 2007

Females of the dung beetle Kheper nigroaeneus rear single offspring from egg to adult on each nesting occasion. In the laboratory, the female's presence improved egg‐hatch/larval‐establishment from 78 to 98% increased survival during the larval feeding stages from 56 to 95% and improved survival of fully‐fed larvae to adult emergence from 0 to 20%. Overall survival in the laboratory was 0% without the female and 19% in the presence of the female. Offspring survival in the laboratory was considerably lower than the 58–84% observed in the field. This difference was attributed to unidentified problems with the rearing method.

MORPHOLOGY AND BIOLOGY OF ACRODZPSAS ZLLZDGEZ (WATERHOUSE AND LYELL), A MYRMECOPHAGOUS LYCAENID (LEPIDOPTERA: LYCAENIDAE: THECLINAE)
Authors: SAMSON P. R.
Published: April 2007

Acrodipsas illidgei (Waterhouse and Lyell) has mynnecophagous larvae associated with the ant Crematogaster sp. (laeviceps group). Eggs were found on the trunk and branches of the mangrove Avicennia marina colonised by the host ant. Two types of epidermal organs, possibly glandular, were identified in first instar larvae, and a Newcomer's organ was present from the second instar onwards. Biology was observed in artificial ant colonies. First instar larvae were carried by the ants and placed near the ant brood where they fed, apparently imbibing the fluid contents of the ant larvae through a hole chewed in the cuticle. Older larvae consumed the whole ant larva or pupa. The function of the larval organs in myrmecophily is discussed.
ELECTROPHORESIS OF HELICOVERPA ARMZGERA (HÜBNER) AND H. PUNCTIGERA (WALLENGREN) (LEPIDOPTERA: NOCTUIDAE): GENOTYPE EXPRESSION IN EGGS AND ALLOZYME VARIATIONS BETWEEN LIFE STAGES
Authors: Fisk Jennifer H. , Daly Joanne C.
Published: April 2007

Eggs of Helicoverpa armigera at various stages of development were subjected to electrophoresis and stained for 3 polymorphic isozymes. Infertile eggs and eggs up to halfway through development produced allozymes corresponding to the maternal genotype. Eggs more than halfway through development showed a combination of the maternal and larval genomes, while shortly before hatching, only the larval genome was detected. In adults, the isozymes IDH‐1 and PGD had a slightly faster mobility than those from other life‐stages. This variation was easily distinguished from the larger inter‐specific allozyme differences observed between H. armigera and its sibling species H. punctigera
GRADED LEVELS OF CHEMICAL DEFENCE IN MIMICS OF LYCID BEETLES OF THE GENUS METMORRHYNCHUS (COLEOPTERA)
Authors: Moore B. P. , Brown W. V.
Published: April 2007

Twelve of the principal coleopteran mimics of the highly chemically protected lycid Metriorrhynchus rhipidius (Macleay) were screened for the presence of chemical repellents. These mimics showed varying responses and formed a graded series ranging from those with full chemical protection at all levels (odour, taste and toxicity) and thus fully comparable with the model, through intermediates protected at some levels, to others without any evident chemical defences and apparently dependent entirely upon protective visual resemblance to the model.

The bearing of these findings on the evolution and classification of mimics is discussed.
LARVAL SURVIVAL IN THE SOIL AND ADULT EMERGENCE IN MELANTERIUS ERICHSON AND PLAESIORHINUS BLACKBURN (COLEOPTERA: CURCULIONIDAE) FOLLOWING SEED FEEDING ON ACACIA AND BOSSIAEA (FABACEAE)1
Authors: Auld Tony D.
Published: April 2007

In the predispersal seed predators Melanterius spp. and Plaesiorhinus spp. (Coleoptera: Curculionidae), larval survival in the soil prior to adult emergence was generally low (10–60%). On average, Melanterius spp. spent 7–10 weeks in the soil in the laboratory and would be expected to emerge as adults in the field in January or February, 6 months before a new seed‐crop becomes available. Plaesiorhinus spp. spend much more time in the soil, in general 35–54 weeks, and emergence in the field would coincide approximately with the next available seed‐crop.
THE PHENOLOGY OF COMSTOCKASPIS PERNICIOSUS (COMSTOCK) (HEMIPTERA DIASPIDIDAE) IN AN APPLE ORCHARD AT ORANGE, NEW SOUTH WALES
Authors: Bower C.C.
Published: April 2007

The phenology of San Jose scale, Cornstockaspis perniciosus (Comstock) was determined in a commercial apple orchard at Orange, New South Wales in 1983/84. Two full generations of C. perniciosus occurred, with a small proportion of the population possibly completing a third generation during winter. A minimum of 741 day‐degrees was required to complete a generation. The first generation of crawlers commenced 261 day‐degrees after capture of the first male in spring. Preliminary recommendations are given for timing pesticide applications against crawlers.

INSECT INDUCED BUD FALL IN CULTIVATED HIBISCUS AND ASPECTS OF THE BIOLOGY OF MACROURA CONCOLOR (MACLEAY) (COLEOPTERA: NITIDULIDAE)
Authors: Gough N. , Hamacek E. L.
Published: April 2007

The influence of insect attack on bud fall and subsequent poor flowering in cultivated hibiscus (Hibiscus rosa‐sinensis) was studied in cages and in the field in southern Queensland. Three species of Hemiptera (most importantly Aulacosternum nigrorubrum Dallas but also Nezara viridula (L.) and Tectocoris diophthalmus (Thunberg)) caused some bud fall in 2 plantations studied. Adult Macroura concolor (Macleay) suppressed flowering for long periods in spring and summer. Data from white funnel traps and counts in flowers showed that M. concolor beetles were most active in these seasons. Methiocarb (0.75 g/L a.i.) reduced beetle numbers and increased flowering. When 15 or more adult M. concolor occurred per bud (or flower) most buds fell and few flowers were produced, but when beetles declined to 10 or fewer many buds survived and widespread flowering occurred. Larvae fed in fallen buds and flowers and the mean duration of development of the combined immature stages was 14 days at 26°C. The preference of adult M. concolor for pale coloured flowers was examined. Hibiscus plants produced most buds from December to June with lower numbers in winter and spring (July to November). Bud production in spring and early summer (September to December) vaned greatly and probably contributed to poor flowering, however, even when large numbers of buds occurred very few flowers were produced because of the activities M. concolor.
POPULATION BIOLOGY OF BIPRORULUS BIBAX BREDDIN (HEMIPTERA: PENTATOMIDAE) IN A SOUTHERN NEW SOUTH WALES CITRUS ORCHARD
Authors: James David G.
Published: April 2007

Population biology of Biprorulus bibax Breddin on citrus was studied during December 1987—June 1988 in southern New South Wales. In 2 lemon groves peak populations of up to 11,670 adult bugs in late January and late March were estimated by the mark, release and recapture method. Large populations of nymphs matured in December/January and March/April. During autumn, adult bugs entered reproductive dormancy and moved to overwintering sites in adjacent Valencia orange trees. Adults were long lived as many marked in the previous summer were recaptured in spring and summer 1988/89. Maximum recorded longevity was 419 days. Intra and inter‐grove movement was observed with bugs found up to 2 km away from site of marking. Parasitism of B. bibax eggs by 3 species of hymenopteran parasitoids was generally low and appeared to have little effect on population regulation, except for a brief period in midsummer.
PEST STATUS OF NYSIUS CLEVELANDENSZS EVANS AND N. VINITOR BERGROTH (HEMIPTERA: LYGAEIDAE) ON COTTON
Authors: Chinajariyawong A. , Walter G. H. , Harris V. E.
Published: April 2007

The pest status of the grey cluster bug (N. clevelandensis Evans) and Rutherglen bug (N. vinitor Bergroth) on cotton has, to date, been unclear. Under laboratory conditions we found that nymphs of both species fail to reach adulthood when fed cotton (tips or squares) alone, and adults are unable to reproduce on such a diet. In no stage of their development were bugs of either species able to damage seedling or early‐squaring cotton, even if no alternative food supply was provided. Our results therefore confirm that neither species is damaging to early‐season cotton.

AN AUSTRALIAN DROSOPHILID (DIPTERA) ON EUCALYOPTUS AND EUGENIA (MYRTACEAE) FLOWERS IN MADAGASCAR
Authors: McEvey S. F. , Aulard S. , Ralisoa‐Randrianasolo O.
Published: April 2007

Drosophila flavohirta Malloch is adapted to life in flowers of Eucalyptus spp. (Myrtaceae) and is widespread in Australia; it is probably an indigenous Australian species. The fly has spread to southern Africa where its proliferation has been associated with falls in honey production. We here record it from Madagascar where it was found in abundance in flowers of Eugenia sp. (Myrtaceae) as well as on Eucalyptus. We predict that it will be found in other parts of the world.
PYETHROID RESISTANCE IN HELIOTHIS ARMIGERA (HÜBNER) COLLECTED FROM UNSPRAYED MAIZE CROPS IN NEW SOUTH WALES 1983–1987
Authors: Gunning R. V. , Easton C. S.
Published: April 2007

Between 1983 and 1987 a survey of pyrethroid resistance in H. armigeru was conducted using samples collected in unsprayed maize crops in New South Wales. The average resistance levels were calculated for early, middle and late stages of each season. Data from the 4 year survey showed 2 periods of similarity. There was low resistance in the 1983/84–1984185 seasons, followed by a major increase in levels 1985/56–1956/87. Almost 50% of H. armigera sampled were pyrethroid resistant individuals in late 1986/87. Reasons for the contamination of refugia by pyrethroid resistant H. armigera and the long term implications to pyrethroid resistance management are discussed. The contamination of non‐sprayed populations by pyrethroid resistance is compared to the spread of DDT resistant H. armigera in New South Wales in the early 1970s.

INSECTICIDE RESISTANCE IN FLIES (DIPTERA: MUSCIDAE) FROM POULTRY FARMS
Authors: Levot G. W. , Hughes P. B.
Published: April 2007

Populations of the house fly, Musca domestica L., and the false stable fly, Muscina stabulans (Fallén), collected on poultry farms west of Sydney were tested against insecticides by topical application. House flies were resistant to the organophosphorus insecticides diazinon, azamethiphos, trichlorphon and malathion and to the carbamate, propoxur. No resistance was detected to the synthetic pyrethroid, permethrin. Resistance factors were generally low for azamethiphos (3x–10x) and somwhat higher for diazinon (8x–22x). A proportion of field flies could survive very high doses of malathion, trichlorphon and propoxur, and resistance factors could not be determined. No resistance to any of the above insecticides was detected in populations of false stable flies. M. stabulans was between 2 and 35 times more susceptible to these insecticides than susceptible house flies, except for permethrin which was equitoxic to both species.
RE‐EXAMINATION OF COMPETITION BETWEEN MUSCA VETUSTISSIMA WALKER (DIPTERA:MUSCIDAE) LARVAE AND SEASONAL CHANGES IN FAVOURABILITY OF CATTLE DUNG
Authors: Ridsdill‐Smith T. J. , Hayles L.
Published: April 2007

Intraspecific competition between different numbers of larvae of bush fly, Musca vetustissima Walker, in one litre pads of decreasing quality of cattle dung collected monthly from October to February was measured in the laboratory at 25°C. Larval size, estimated from the headwidths of emerging flies, showed the same maximum in dung collected from October to January. For a family of curves only one parameter, the ‘exponent, was needed to describe the effect of dung quality on the relation between dung supply/egg and size. Dung supply/egg at which competition occurred increased from 1 mL in October to 13 mL in January. In February dung all flies were smaller and survival was lowest. Survival in any month was not correlated with dung supply/egg, but was positively correlated with adult size up to a threshold of 2 mm headwidth. When bush fly populations in the field are increasing and dung quality is decreasing, the fall in size, and thus fecundity, is predicted to occur earlier in the season because of these interactions between dung supply/egg and dung quality than would be predicted from laboratory bioassays which assume that no interactions occur.

IMMATURE STAGES AND LIFE HISTORY OF ENYTUS SP. (HYMENOPTERA: ICHNEUMONIDAE), A PARASITOID OF PERTHIDA GLYPHOPA COMMON (LEPIDOPTERA: INCURVARIIDAE)
Authors: Mazanec Z.
Published: April 2007

The egg, 3 larval instars and pupa of Enytus sp. a univoltine, primary endoparasitoid on the feeding larva of the jarrah leafminer Perthida glyphopa Common, are figured and its life history described. Single eggs laid in July and August hatch rapidly, but the caudate larva develops slowly, allowing the host to complete feeding, construct its cell and aestivate in the soil. The parasitoid's final instar larva destroys the host in March, April or May of the following year, spins a cocoon and pupates in the cell where ecdysis occurs. The species was found most frequently in areas of low host density.
EFFECT OF TEMPERATURE ON EGG DEVELOPMENT IN COPRIS HISPANUS L. AND BUBAS BISON (L.) (COLEOPTERA: SCARABAEIDAE)1
Authors: Kirk A. A. , Kirk G.
Published: April 2007

Developmental thresholds of 7.2 and 11.1°C are reported for the eggs of the Mediterranean dung beetles Bubas bison and Copris hispanus respectively. Total day‐degrees for egg development were 169 and 117 respectively. Mortality of B. bison eggs was negligible up to 20°C, 50% at 25°C and 100% at 30°C. C. hispanus egg mortality was 45% from 15–30°C. B. bison oviposits throughout the cool mediterranean winter‐spring period and C. hispanus during the hot early summer period. Their eggs are well adapted to those conditions.

TOXICITY OF THREE AVERMECTINS TO INSECTICIDE SUSCEPTIBLE AND RESISTANT LARVAE OF LUCILIA CUPRINA (WIEDEMANN) (DIPTERA: CALLIPHORIDAE)
Authors: Hughes P. B. , Levot G. W.
Published: April 2007

The toxicity of 3 avermectins–ivermectin, abamectin and 4‐deoxy‐4‐epi (methyl amino) avermectin B1–to larvae of the sheep blowfly, Lucilia cuprina, was determined by in vitro bioassay. Mean LC50 values for the susceptible reference strain were between 0.0021 mg/L and 0.0028 mg/L for the 3 compounds. Similar values were obtained for 11 field populations. The organophosphorus/carbamate resistant strain had mean LC50 values between 0.0029 mg/L and 0.0067 mg/L. Despite this small difference between strains, the potency of the avermectins against both susceptible and OP/carbamate resistant larvae demonstrates their potential as insecticides for the control of flystrike.
THE IMMATURE STAGES AND BIOLOGY OF CHRYSONOTOMYIA SP.A (HYMENOPTERA: EULOPHIDAE), A PARASITOID OF PERTHIDA GLYPHOPA COMMON (LEPIDOPTERA: INCURVARIIDAE)
Authors: Mazanec Z.
Published: April 2007

Biology of the polyphagous, multivoltine Chrysonotomyia sp.A, an internal parasitoid of the jarrah leafminer, Perthida glyphopa, is described and morphology of the egg, 3 larval instars and pupa figured. Most frequently the female parasitoid deposits a single egg into a non‐feeding larva at the end of instar 2 or a feeding larva of instar 3. The parasitoid egg and larva develop in the liquefied contents of the host and the pupa forms within the host's mine. In the laboratory, incubation of the egg and the development of the larva required approximately 6.5 d and the completion of the pupal stage an additional 32 d. In 1986 only 3.0% larvae were parasitised at a site where the leafminer was abundant and 17.0 and 23.3% at 2 other sites where densities were low. Parasitism was inversely correlated with host density and positively correlated with the mean weekly temperature.
THE IMMATURE STAGES AND LIFE HISTORY OF DIAULOMORPHA SP. (HYMENOPTERA: EULOPHIDAE), A PARASITOID OF PERTHIDA GLYPHOPA COMMON (LEPIDOPTERA: INCURVARIIDAE)
Authors: Mazanec Z.
Published: April 2007

The immature stages of the multivoltine, polyphagous, solitary or gregarious Diaulomorpha sp., an external parasitoid on larvae of the jarrah leafminer Perthida glyphopa, are figured and the life history described. Adult females seek out third and fourth instar host larvae feeding in mines, but prefer those of the least abundant and less active stage preparing to moult at the end of instar 3. The host is stabbed, an egg laid in the mine, and after hatching the parasitoid larva feeds on the dead leafminer. Duration of the life cycle in the field, strongly influenced by temperature, is approximately 30 days. In 1986 the parasitoid caused mortality to 5.3% of the feeding larvae at a site of high leafminer population density and 9.9% at another where the leafminer was scarce. Parasitism was inversely correlated with host density and positively correlated with mean weekly temperature.
LASOFINIUS GEN. N. (COLLEMBOLA: TOMOCERIDAE) FROM TASMANIA AND A RE‐EXAMINATION OF NEOPHORELLA DUBIA WOMERSLEY (TOMOCERIDAE)
Authors: Ireson J. E. , Greenslade Penelope
Published: April 2007

Lasofinius gen. n. is erected for L. willi sp.n. (type species) and L. gemini sp.n., both from Tasmania. The species are described and a key to separate them is given. Lasofinius is characterised by the retention of a postantennal organ in adults which is unusual in the Tomoceridae. The closely related monobasic genus Neophorella Womersley from South Africa (type species N. dubia) is redescribed. The phylogenetic relationships of both genera are discussed and comments made on the distribution and zoogeography of Tomoceridae in Australia.
FIELD OBSERVATIONS OF SENOSTOMA SPP. (DIPTERA: TACHINIDAE) AT KATOOMBA, N.S.W.
Authors: Barraclough D. A.
Published: April 2007

Habitats, microhabitats and behaviour of Senostoma longipes (Macquart), S. pallidihirtum (Malloch) and S. tessellatum (Macquart) at Katoomba Falls Reserve, N.S.W. are reviewed. All species favour dry sclerophyll forest on ridge‐tops. Males aggregate on Eucalyptus trunks, females on trunk bases and surrounding substrate. Orientation and postures on trunk surfaces are described. Males compete intraspecifically for apparently favoured sectors of trunk (territories). Competition involves interactions of specimen pairs in flight and on the bark. Trunks are postulated to be leks, as symbolic territories competed for here are devoid of resources for females.

MORPHOMETRIC ANALYSIS OF VARIATION IN NALA LIVIDIPES (DUFOUR) AND LABIDURA TRUNCATA KIRBY (DERMAPTERA: LABIDURIDAE)
Authors: Simpson G. B. , Mayer D. G.
Published: April 2007

Two male morphs occur in populations of Nala lividipes (Dufour), the black field earwig, and of Labidura truncata Kirby, the common brown earwig, distinguished by the presence or absence of a tooth at the mid‐point on each forceps branch. Multivariate morphometric analyses using discriminant function analysis applied to measurements of various body parts of wild‐caught specimens showed that the morphs were statistically separate in both species. In each species female size is intermediate to that of the 2 male morphs. The results are discussed on the basis of natural selection, and possible reasons given for the maintenance of 2 male morphs but only 1 female morph.
ANOPHELES ANNULIPES WALKER (DIPTERA: CULICIDAE) AT GRIFFITH, NEW SOUTH WALES. 1. TWO SIBLING SPECIES IN SYMPATRY
Authors: Foley D. H. , Bryan J. H.
Published: April 2007

The existence of 2 sibling species of An. annulipes at Griffith, NSW is confirmed. The 2 species have been designated as species A and species G. In laboratory produced hybrids, the larval polytene chromosomes are largely asynaptic. The 2 species differ at the malic enzyme and the α‐glycerophosphate dehydrogenase loci. No hybrid chromosomes were detected in the offspring of 103 wild‐caught females from an area of sympatry and 98.5% of 6630 specimens from the same area were identified as either species A or species G by electrophoresis.

THE EARLY STAGES OF GASTRIDIOTA ADOXIMA (TURNER) (LEPIDOPTERA: BOMBYCOIDEA) AND ITS FAMILY PLACEMENT
Authors: Common I. F. B. , Edwards E. D.
Published: April 2007

The monotypic genus Gastridiota Turner is transferred from the Eupterotidae to the Bombycidae. The immature stages of G. adoxima (Turner), here described and figured, provide characters in addition to those of wing venation, which support the transfer. The characters include the presence in the final instar larva of minute scattered secondary setae, paired extensible filaments on some abdominal segments and a dorsal horn on abdominal segment 8. The food plant family, Moraceae, is shared with many other Bombycidae. The native species of Bombycidae in Australia are briefly discussed.

ESTABLISHMENT OF ACANTHOSCELIDES QUADRIDENTATUS (SCHAEFFER) AND A. PUNICEUS JOHNSON (COLEOPTERA: BRUCHIDAE) ON MIMOSA PIGRA IN NORTHERN AUSTRALIA
Authors: WILSON C. G. , FLANAGAN G. J.
Published: April 2007

The Mexican seed‐feeding bruchids Acanthoscelides quadridentatus (Schaeffer) and A. puniceus Johnson were released at 32 sites, in 6 Mimosa pigra L. infestations in the Northern Territory between 13 April 1983 and 3 December 1985. Both species established but their impact on M. pigra populations has been negligible. Field collections over a 6 year period showed that 0.8% of M. pigra seeds were destroyed by the bruchids, and that 97.8% of bruchids recovered were A. puniceus.

EFFECT OF TEMPERATURE ON DEVELOPMENT, SURVIVAL, LONGEVITY AND FECUNDITY OF TRISSOLCUS OENONE DODD (HYMENOPTERA: SCELIONIDAE)
Authors: JAMES DAVID G. , WARREN GLEN N.
Published: April 2007

The effect of temperature on the rate of development of Trissolcus oenone was determined by rearing individuals on eggs of Biprorulus bibax Breddin under a range of constant temperatures (12.5–5.0°C). Rates of development changed in a linear fashion over a wide range of temperatures. The lower developmental threshold was estimated to be 12.4°C and an estimated 165.5 degree‐days were required for egg‐adult development. Survival of developing parasitoids ranged between 60–90% at most temperatures. Wasps produced progeny at all temperatures between 15–35°C and total production of offspring ranged from 55.9–163.1. Greatest fecundity occurred at 17.5, 22.5 and 25°C. Longevity did not differ between virgin and mated females and was greatest at 17.5°C (46.7 d) and least at 32.5°C (11.7 d).

EFFECTS OF DELAYED MATING ON THE REPRODUCTION OF PECTINOPHORA SCUTIGERA (HOLDAWAY) (LEPIDOPTERA: GELECHIIDAE)
Authors: WALKER P. W.
Published: April 2007

At 25°C, virgin female Pectinophora scutigera were paired with a single virgin male of the same age < 1, 10, 20 and 30 d after eclosion. Delayed mating significantly reduced the proportion of females laying fertile eggs, the total number of eggs laid per female, and the duration of oviposition, but did not affect the preoviposition period, percentage egg hatch, or the “effective” longevity of females (number of days from eclosion to last fertile egg laid). The number of first instars produced per female was reduced by 40.2, 55.7 and 65.9% when mating was delayed for 10, 20 and 30 d, respectively. The results are discussed in relation to the control of P. scutigera by mating disruption with synthetic sex pheromone.
NOTES ON PHYLLOCNISTIS CITRELLA STAINTON (LEPIDOPTERA: PHYLLOCNISTIDAE) ATTACKING FOUR CITRUS VARIETIES IN DARWIN
Authors: Wilson Colin G.
Published: April 2007

Phyllocnistis citrella Stainton occurred throughout the year at Darwin in the Northern Territory and attacked more than half of the new leaves produced on 4 varieties of citrus. A mean of 5.9 eggs per leaf was recorded, with 32.7% on the upper surface. Only 5.2% of larvae pupated, with most succumbing to crowding. During the hottest months the life cycle was completed in 14–18 days. Citrus paradisi Macfadyen (var. Marsh's seedless grapefruit) was the most susceptible of the citrus varieties examined.
TWO NEW GENERA OF HARPACTORINAE (HEMIPTERA: REDUVIIDAE) FROM NORTHERN AUSTRALIA
Authors: Malipatil M. B.
Published: April 2007

Two new genera, Undiareduvius (type species U. aquilonius sp.n.) and Gorareduvius (type species G. westraliensis sp.n.) are described and illustrated from northern Western Australia and the Northern Territory and are placed in the subfamily Harpactorinae. U. aquilonius has been observed to gather sticky exudate from the leaves of the grass Triodia (which it frequents) on its centrally swollen fore tibia, presumably to assist prey capture. The relationships of the new genera with other Australian harpactorines are noted.
SOIL TEXTURE AND THE DISTRIBUTION OF ANTITROGUS PARVULUS BRITTON, LEPIDIOTA CRINITA BRENSKE AND L. NEGATORIA BLACKBURN (COLEOPTERA: SCARABAEIDAE) IN SOUTH QUEENSLAND SUGARCANE FIELDS
Authors: Cherry R. H. , Allsopp P. G.
Published: April 2007

Thirty sugarcane fields located on different soil types in southern Queensland were sampled for the melolonthine canegrubs Antitrogus parvulus Britton, Lepidiota crinita Brenske and L. negatoria Blackburn. Soil parameters (sand, silt, clay, pH) were also measured for each field. Correlations between the relative abundance of the canegrub species and soil parameters were determined. Distinct soil preferences were shown among 2 of the 3 canegrub species. A. parvulus abundance was positively correlated with clay and silt content and negatively correlated with sand content. L. negatoria abundance was positively correlated with sand content and negatively correlated with clay and silt content. L. crinita abundance showed no significant correlations with sand, silt, or clay content. The abundance of none of the 3 species showed any significant correlation with soil pH.
