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

AbstractThe 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

AbstractThe 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

AbstractPatterns 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)

Published: April 2007

Abstract 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

AbstractFemales 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

Abstract 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

AbstractEggs 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

AbstractTwelve 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

AbstractIn 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

AbstractThe 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

AbstractThe 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

AbstractPopulation 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

AbstractThe 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.

Authors: McEvey S. F. , Aulard S. , Ralisoa‐Randrianasolo O. 
Published: April 2007

AbstractDrosophila 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

AbstractBetween 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

AbstractPopulations 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

AbstractIntraspecific 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.
