Published: January 2008

AbstractObjectiveTo identify and describe characteristics of the bias of reported energy intake of participants in the Gothenburg Osteoporosis and Obesity Determinants (GOOD) study.DesignA validated diet history with a detailed questionnaire and an interview was used. Body fat was analysed by dual-energy X-ray absorptiometry. The ratio of energy intake (EI) to BMR was used to define under-reporters (EI:BMR < 1·30), acceptable reporters (EI:BMR ≥ 1.30 to <2.64) and over-reporters (EI:BMR ≥ 2.64).SettingSahlgrenska University Hospital, Gothenburg, Sweden.SubjectsA total of 695 males (18–20 years).ResultsSixty-eight per cent were classed as acceptable reporters, 22 % as over-reporters and 10 % as under-reporters. The under-reporters had higher BMI and body fat percentage than acceptable reporters (P < 0·001), while over-reporters had lower BMI and body fat percentage (P < 0·001). Over-reporters had more frequent use of protein supplements than acceptable reporters and higher physical activity. Over-reporters had a more regular and under-reporters a less regular meal pattern compared with acceptable reporters.ConclusionsImportant knowledge of dietary reporting bias in a previously sparsely studied population has been provided. Over-reporting of energy intake was more common than under-reporting in the present population of young men and characteristics of under- and over-reporters were identified. The GOOD study was initiated with the central aim to determine environmental and genetic factors involved in the regulation of bone and fat mass, and the nutrient data of the acceptable reporters can be used for further investigation of the health effects of energy and nutrient intake.

A description and classification of some final—instar larvae of the Mesochorinae (Hymenoptera, Ichneumonidae)
Authors: SHORT J. R. T. 
Published: January 2008

AbstractThe characters of the final–instar larvae of the Mesochorinae are reviewed on knowledge of species belonging to four genera. Relationships indicated by larval characters, within the Mesochorinae, and between the Mesochorinae and other groups of rchneumonidae, are outlined. Evidence is given that the larval characters of Cidaphus indicate this genus to be the least specialized of the Mesochorinae.
A new species of parasitic midge (Forcipomyia (Pterobosca)) from Aldabra, with descriptions of its presumed larva and pupa and systematic notes on the subgenera of Forcipomyia (Ceratopogonidae)
Authors: WIRTH WILLIS W. , RATANAWORABHAN NIPHAN CHANTHAWANICH 
Published: January 2008

Abstract Forcipomyia (Pterobosca) hutsoni n.sp. is described and figured from adults of both sexes and from putatively identified larvae and pupae. The species is common on Aldabra Atoll in the Indian Ocean. Most adult females were taken from the wings of Odonata. Immature stages were found in Pandanus leaf axils and are the first to be described for the subgenus Pterobosca. Characters of the three stages show that biting midges of this subgenus are most closely related to the subgenera Phytohelea, Trichohelea and Rhynchoforcipomyia. The subgenera Thyridomyia, Synthyridomyia and probably Blantonia fall in a second section of the genus, while Lasiohelea forms a third and intermediate section.

Geographical variation in the genitalia of three species of Cicadellidae (Hemiptera)
Authors: LE Quesne W. J. , Woodroffe G. E. 
Published: January 2008

AbstractSpecimens of three species of Cicadellidae, Agallia laevis Ribaut, Eupteryx stachydearum Hardy and E.urticae Fabricius, are examined from different parts of their distribution in Europe and differences in genital characters are recorded. Variation in Agallia laevis suggests a dine or stepped cline from S.E. to N.W. in the shape of the anal appendages and aedeagus, while E. stachydearum shows a N–S cline, and a similar altitudinal cline, in the length and curvature of the apical processes of the aedeagus. In E.urticae geographical variation in the size and direction of the same processes also clearly occurs, though the exact pattern is not yet clear.
The Neotropical genus Anaisus (Elateridae) and its relationship to the Pyrophorinae

Published: January 2008

AbstractFour species of the genus Anaissus Candeze are recognized and described or redescribed and a key for their identification is given; anandra sp.n., aurantium spn., fuscipes sp.n. and tarsalis Candeze (=spinipennis syn.n.). A new subgenus Auctumnalis is erected with aurantium as type‐species. Two possible species from Brazil and French Guiana respectively are also reported. The systematic position of the genus is discussed in relation to the Neotropical Pyrophorinae, and on the basis of adult characters Anaissus is here assigned to the subfamily Pyrophorinae.
Scanning electron microscope study of the palar pegs of three species of Corixidae (Hemiptera)
Authors: FURTH DAVID , ALBRECHT RENATA , MURASZKO KARIN , HUTCHINSON G. EVELYN 
Published: January 2008

AbstractScanning electron microscope studies were performed on the palar pegs of male forelegs of Trichocorixa sexcincta, Sigara alternata and Hesperocorixa interrupta. The studies showed the pegs to be basically conical and chevron‐ridged, with a wide base that tapered of to a narrow apex. Clear species differences were apparent with respect to the size of the peg, the number of ridges on an individual peg, and the number and arrangement of the pegs on the pala. The possible behavioural and evolutionary significance of the palar pegs is discussed in relation to mating.

Relationships of the Musca domestica subspecies calleva and curviforceps (Diptera: Muscidae) in Rhodesia
Authors: HULLEY P. E. 
Published: January 2008

Abstract. Field investigations on Musca domestica houseflies in Rhodesia demonstrate a greater degree of contact than previously reported between domestic M. d. curviforceps and feral M. d. calleva at their habitat interface. There was no evidence of any seasonal disappearance of hybrid flies; stable, intermediate, largely domestic populations are a feature of areas of sympatry. The existence of almost pure calleva feral populations in these areas was verified, though a slight degree of introgression with curviforceps was demonstrated for the first time. Gene‐flow between the subspecies was studied and a new explanation for the one‐way gene‐flow, based on habitat choice of hybrid flies, is advanced.Frons ratio, widely used in distinguishing different forms of housefly, showed serious limitations as a taxonomic character. The ratio, intended as a size‐adjusted measure of frons width, is not independent of size, and frons width and head width (shown to be a good measure of size) are at best weakly correlated. It was confirmed that the frons width of male calleva×curviforceps hybrids is stabilized at the fronJ width characteristic of curviforceps although laboratory breeding results indicate that intermediate frons widths are to be expected. The stabilization is due to selection for broader frons width in the domestic habitat. The nature of the selection is explained, and evidence is produced regarding its basis.
Papilio nandina, a probable hybrid between Papilio dardanus and Papilio phorcas
Authors: Hon Sir CYRIL CLARKE 
Published: January 2008

Abstract. Hybrids bred in the laboratory between Papilio dardanus Brown and Papilio phorcas Cramer resulted in male butterflies similar to the two naturally occurring males described as P.nandina Rothschild & Jordan. A single female hybrid insect resembling the female parent was also bred. Male hybrids were also obtained between P.dardanus and P.demodocus/demoleus but not between P.dardanus and P.constantinus.The phylogenetic relationships of dardanus and phorcas are discussed, and reasons given for preferring the older hypothesis that male‐like females are primitive rather than that they represent the most specialized forms. Further information on this point would be forthcoming if backcrosses and F2 s could be obtained.

Abnormalities of wing pattern in the Eastern Tiger Swallowtail butterfly, Papilio glaucus
Authors: Hon CYRIL CLARKE 
Published: January 2008

Abstract In much of its range Papilio glaucus L. has two forms of female, black and yellow, and the gene controlling the colour pattern is on the Y chromosome. Thus black mothers produce only black daughters and yellow mothers produce yellow daughters. Reasons are given to explain the occasional exceptions to this rule. The black female form mimics Battus philenor (L.), and an autosomal mutant is described in P.glaucus which is paralleled by a similar aberration in the model ‐ a possible example of a model ‘escaping’ from a mimic and the mimic ‘catching up’ at one step.Sex mosaics are readily seen in the black form of glaucus females and a numberare described from the Strecker collection. The probable cytogenetic constitution of these aberrations is discussed.Hybrids are described between glaucus and its near relatives, P.rutulus Lucas, P.eurymedon Lucas and P.multicaudatus Kirby. These crosses produce mainly males but, by the use of ecdysterone, females have been obtained in the cross between the black female form of glaucus and the male of rutulus.

Morphometric studies of some Pteromalus Swederus species (Hymenoptera: Chalcidoidea) with emphasis on allometric relationships, or: Are ratios reliable in chalcid taxonomy?
Authors: JANZON LARS‐ÅKE 
Published: January 2008

AbstractTwenty‐four ratios, very commonly used among hyme‐nopterists, were studied in order to determine the extent to which allometry influences a given measure. On basis of regression lines, this. investigation reveals that about 60% of the ratios show errors caused by allometry. E.g. it is advisable to correct POL/OOL, Postmarginal vein/Marginal vein and Mesoscutum length/Thorax length before utilizing them as species separating character states. In this study females belonging to the Pteromalus albipennis group (Hymenoptera, Chalcidoidea) were examined.

A new species of Asterolecanium Targioni Tozzetti (Homoptera: Asterolecaniidae) on a palm in Round Island, Mauritius: a conservation puzzle
Authors: WILLIAMS D. J. , MAMET J. R. 
Published: January 2008

Abstract Asterolecanium dictyospermae sp.n., a sap‐sucking scale insect, is described here from Round Island, Mauritius, where it is apparently specific to only two surviving trees there of the palm Dictyosperma album var. conjugatum. Although this palm variety occurs also in small numbers on the main island of Mauritius, it interbreeds there in cultivation with two other varieties of this palm species and may be preventing these trees from producing pure seed. A.dictyospermae has probably evolved on Round Island with the palm variety, but now that the palm is under stress from other causes the numbers of scale insects have increased, thereby threatening the survival of not only the palm variety, but of the scale insect itself.
Review of the Order Strepsiptera
Authors: KATHIRITHAMBY JEYARANEY 
Published: January 2008

AbstractThe morphology, biology and life history of the immature stages, the free‐living and the neotenic females (of the suborders Mengenillidia and Stylopidia respectively) and the free‐living males of the order Strepsiptera are discussed. Strepsiptera are entomophagous parasitoids and are known to parasitize seven orders and thirty‐five families of Insecta. The morphological and physiological changes they cause to the host insect are outlined. The classification of the order is revised; the geographical distribution, phylogenetic system and keys to the families, subfamilies and genera (when possible) are given. As the sexes are dimorphic, separate keys are provided for adult males and neotenic females.
Larvae of northern EuropeanHydroporus(Coleoptera: Dytiscidae)
Authors: NILSSON ANDERS N. 
Published: January 2008

AbstractA key is presented to the third‐instar larvae of twenty‐seven northern European species ofHydroporusClairville. Based on reared specimens from northern Sweden, the third‐instar larva is described for the first time for seven species:H.neglectusSchaum,H.scalesianusStephens,H.acutangulusThomson,H.glabriusculusAubé,H.puberulusLeConte,H.tristis(Paykull) andH.incognitusSharp. In the descriptions leg chaetotaxy is emphasized and a distinction is made between primary and secondary setae. Plesiomorphic and apomorphic states are determined for a set of twelve larval characters, and their distribution among the twenty‐seven known species is given. Character distribution is analysed with respect to the phylogenetic status of some subgenera, and it is concluded that bothSternoporusFalkenström andHydroporinusGuignot are junior subjective synonyms ofHydroporus(s.str.). Larval characters are presented also for a selection of some other hydroporine species and their phylogeny is discussed. With respect to larval morphology,Hydroporusis seemingly the most primitive genus of the European Hydroporini, withH.neglectusandH.scalesianusas its most primitive species. The genusMetaporusGuignot is identified as the probable sister‐group ofHydroporus.
The biology, egg and larvae of Acaenitus dubitator (Panzer) (Hymenoptera, Ichneumonidae: Acaenitinae)
Authors: SHAW MARK R. , WAHL DAVID B. 
Published: January 2008

Abstract Acaenitus dubitator (Panzer) is found to be a koinobiont endoparasitoid of the larva of an endophytic beetle, Cleonis piger (Scopoli) (Curculionidae), in Britain, suggesting a similar mode of development for the ichneumonid subfamily Acaenitinae as a whole. The parasitoid can overwinter in its cocoon in one of two ways. Individuals overwintering as essentially unaltered mature larvae do not become adult the following summer, while those that overwinter as morphologically distinct prepupae are committed to pupate and become adult immediately afterwards. The change from mature larva to prepupa takes place in late summer, soon after the time of cocoon formation, but a proportion of mature larvae lie over in the first year, and perhaps subsequently. This appears to be an adaptation to life in a particularly harsh and uncertain environment. The egg, prepupa, and first, second and final instar larvae are described and figured. Previous interpretations of the cephalic sclerites of final instar acaenitines are revised.
A cladistic analysis of the nomadine bees (Hymenoptera: Apoidea)
Authors: ALEXANDER BYRON 
Published: January 2008

Abstract. This study compares the results of Rozen's cladistic analysis of the larvae of fifteen genera of cleptoparasitic bees in the subfamily Nomadinae with an independent data set of adult characters for the same genera. Adult characters exhibited considerably higher levels of homoplasy and poorer resolution of cladistic relationships, with multiple equally parsimonious cladograms. However, comparison of a Nelson consensus tree based on adult characters with the cladogram based on larval characters reveals three components consistently supported in both analyses (the tribes Epeolini and Ammobatini, and Neopasites+Neolarra), one component supported only by adult characters (Isepeolus + Protepeolus), and one terminal component supported only by larval characters (Nomada+ Ammobatini), as well as several more inclusive groupings based on larval characters that are difficult to compare with the adult consensus tree because it shows so much less resolution. When adult and larval characters are combined in a single data matrix, the resulting cladogram closely resembles the cladogram based on larval characters alone, although levels of homoplasy are considerably higher than in the larval analysis.A preliminary analysis of adult characters for thirty‐four genera in the Nomadinae also exhibited high levels of homoplasy and very large numbers of equally parsimonious cladograms. Nevertheless, certain consistent monophyletic groupings, most notably the Epeolini and Ammobatini, were also supported in this analysis. The one currently recognized tribe whose monophyly has received no support from any analysis is the Nomadini.The relevance of these phylogenetic hypotheses to our understanding of host associations and variable features of egg morphology and oviposition behaviour in nomadine bees is briefly discussed.
