NESTS, BEHAVIOUR AND LARVAE OF THE BEE STENOTRITUS PUBESCENS (SMITH) AND BEHAVIUR OF SOME RELATED SPECIES (HYMENOPTERA: APOIDEA: STENOTRITINAE)
Authors: Houston Terry F. 
Published: April 2007

ABSTRACTNests, provisions, and second and last larval instars of Stenotritus pubescens are described and figured for the first time. Nests were found aggregated in a soil slope. Two nests excavated differed from those of other ground‐nesting colletid bees in having cemented upper shaft walls, blind lateral tunnels, complete absence of any cellophane‐like linings, and moulded ovoid pollen masses resting in globules, possibly honey.Observation of the flight activity, foraging, mating and male territoriality of S. pubescens are recorded with brief notes on some related species.The information presented in considered to support a belief that stenotritine bees are misplaced in the family Colletidae.
DURATION OF TOXICITY OF RESIDUES OF MALATHION AND SPRAY OIL ON CITRUS FOLIAGE IN SOUTH AUSTRALIA TO ADULTS OF A CALIFORNIA RED SCALE PARASITE APHYTIS MELINUS DeBACH (HYMENOPTERA: APHELINIDAE)
Authors: Campbell M. M. 
Published: April 2007

ABSTRACTAdult Aphytis melinus were exposed in the laboratory to leaves of orange trees collected at intervals after the trees were sprayed with malathion, oil, or nutrients. Residues of 0.15% malathion applied in late winter, spring, and summer were highly lethal for 29, 21, and 16 d respectively, and weathered in 48, 41, and 27 d respectively to a level that allowed 50% survival after 4 h. The residue from 2.5% pre‐emulsified oil applied in summer was highly lethal for 1 d and at 8 d was no longer toxic. Survival of adults was not reduced by exposure for 20 h to the residue, immediately after drying, from nutrient sprays containing 0.2% zinc oxide, 0.4% manganese sulphate, and/or 0.7% urea applied in summer.
STERILIZATION OF DACUS CUCUMIS FRENCH (DIPTERA: TEPHRITIDAE) BY GAMMA RADIATION. II. EFFECT OF DOSE RATE ON STERILITY AND COMPETITIVENESS OF ADULT MALES
Authors: Hooper G. H. S. 
Published: April 2007

ABSTRACTNewly emerged adult males of Dacus cucumis were irradiated with 1, 3 and 5 krad of gamma radiation at dose rates of 9.51. 4.38, 2.98 and 0.87 krad/min. There was no significant effect of dose rate on sterility or longevity. When males were irradiated with 7 or 9 krad at rates of either 9.51 or 0.87 krad/min there was no significant effect of dose rate on competitiveness of the males. A dose of 9 krad gave significantly less competitive males than did a dose of 7 krad.
AERIAL DISPERSAL OF SOME VICTORIAN PSOCOPTERA AS INDICATED BY SUCTION TRAP CATCHES
Authors: New T. R. 
Published: April 2007

ABSTRACTThe Psocoptera captured in susction traps operated at Warrandyte and Bundoora (Victoria) throughout 1972 and 1973 are enumerated and discussed. Twenty‐nine species were captured, but the bulk of the catches were comprised of a few species of Caecilius, Ectopsocus, Peripsocus and Propsocus. Seasonal variations in catches are discussed briefly in relation to the life cycles of these taxa, and the sex ratios and diversity of Psocoptera caught are compared with earlier catches in Britain.

TOXICITY OF INSECTICIDES TO ADULT AUSTRALIAN PLAGUE LOCUST, CHORTOICETES TERMINIFERA (ORTHOPTERA: ACRIDIDAE)
Authors: Edge V. E. , Casimir M. 
Published: April 2007

ABSTRACTFenitrothion and malathion are the standard insecticides used in the aerial spraying of swarms of Australian plague locust, Chortoicetes terminifera, in New South Wales. The toxicities of these and 11 other insecticides to adult C. terminifera were determined by topical application. Phoxim (LD50 0.6 μg/g) was the most effective insecticide, being 6.6 × more toxic than fenitrothion (LD50 4.0 μg/g) and 33 × more toxic than malathion. Compared to fenitrothion 5 other insecticides were significantly more toxic at the LD50 level: chlorpyrifos (2.8 ×), diazinon (1.8 ×), arprocarb (1.7 ×), and the synthetic pyrethroids, ethanochrysanthemate (2.5 ×) and cismethrin (2.0 ×), Bioresmethrin and the photostable pyrethroid permethrin (NRDC 143) were 0.5–0.8 × and 0.4 × as toxic respectively as fenitrothion. The synergist piperonyl butoxide increased the efficacy of bioresmethrin and permethrin by 3.9 × and 8.2 × respectively.
TWO RACES OF THE KANGAROO TICK ORNITHODOROS (PAVLOVSKYELLA) GURNEYI WARBURTON
Authors: Doube B. M. 
Published: April 2007

ABSTRACTTwo biological‐physiological races of the kangaroo tick Ornithodoros gurneyi have been identified. One was found in soil in caves in ranges in Queensland, Northern Territory, South Australia and Western Australia, and the other in soil under trees in open savannah country in New South Wales and South Australia. The cave race is smaller than the plains race. Examination of nymphs and adults under the light microscope and EMS micrographs of larvae revealed no structural differences between the two races. There are significant physiological differences between the two races. Limited cross fertilisation experiments produced viable larvae.
ON THE RESPIRATORY SYSTEM OF THE LEMON‐BUTTERFLY, PAPILIO DEMOLEUS L.* (LEPIDOPTERA: PAPILIONIDAE)†
Authors: Srivastava K. P. 
Published: April 2007

ABSTRACTThe spiracular and tracheal systems of the lemon‐butterfly, Papilio demoleus are described in detail. The insect has 9 pairs of spiracles of which 2 are located in the thorax and 7 in the abdomen. Only the second thoracic spiracle has the external closing mechanism, the rest having the internal closing mechanism. The tracheae of the preabdominal region are largely thin walled, without taenidia and easily collapsible while those of the abdomen have taenidia and are not easily collapsible. The tracheal air‐sacs are largely present in the preabdominal region. Some tracheae that do not tracheate any organ but open into another trachea or air‐sac have been referred to as the tracheal shunts. Their possible function is to feed additional air to the branches or air‐sacs into which they open. The spiracular tracheae maintain a fairly uniform (generalised) branching pattern throughout different segments.
THE ANATOMY OF THE NERVOUS SYSTEM IN THE QUEENSLAND FRUIT FLY DACUS TRYONI (FROGGATT)*
Authors: Armati Patricia 
Published: April 2007

ABSTRACTThe central nervous system of Dacus tryoni is highly condensed. All the cephalic ganglia are concentrated in a single mass through which the oesophagus passes, and there are separate thoracic and abdominal ganglionic masses. Peripheral nerves, which are described in detail, show considerable variability in the abdomen. The stomatogastric nervous system comprises frontal and hypocerebral ganglia connected by the recurrent nerve, which also innervates the corpus cardiacum and corpora allata. The nervi corporis cardiaci join the recurrent nerve close to the brain within the oesophageal tunnel.

CRASPEDOCHAETA DECEPTIVA (MALLOCH), A SYNONYM OF C. PUNCTIPENNIS (WIEDEMANN) (DIPTERA: ANTHOMYIIDAE)*
Authors: VOCKEROTH J. R. 
Published: April 2007

Abstract Craspedochaeta deceptiva (Malloch, 1921), a species recorded only from Australia and New Zealand, was considered by Malloch to be closely related to C. punctipennis (Wiedemann, 1830), a species from southern South America, and by Hennig to show a close resemblance to punctipenis due to symplesiomorphy. It is shown here that C. deceptiva is a synonym of C. punctipennis, and that the Australian and New Zealand populations have almost certainly been introduced by human agency during the present century.
EFFECT OF A JUVENILE HORMONE ANALOGUE ON MORPHOLOGY, REPRODUCTION AND ENDOCRINE ACTIVITY OF THE COWPEA APHID, APHIS CRACCIVORA KOCH
Authors: Elliott H. J. , Mcdonald F. J. D. 
Published: April 2007

ABSTRACTTopical application of AltozarTM†, at rates as low as 0.7 nanograms per aphid, caused severe morphological changes and prevented larviposition when applied to third instar Aphis craccivora, although treatment of other instars was less effective. Aphids which failed to reproduce contained fewer oocytes and embryos than untreated aphids, but enormous development of the embryos had occurred, and oocytes within these embryos also exhibited exaggerated development. The reproductive tract of treated aphids was distorted and non‐functional presumably due to pressare from the hyper‐developed embryos. The volume and mean nuclear size of the corpus allatum of treated aphids were significantly smaller than in untreated controls (newly‐moulted adults) and the effect of the chemical on the endocrine system is discussed. Neurosecretory staining revealed no difference between treated and untreated aphids.
STERILIZATION OF DACUS CUCUMIS FRENCH (DIPTERA: TEPHRITIDAE) BY GAMMA RADIATION
Authors: Hooper G. H. S. 
Published: April 2007

ABSTRACTWhen newly emerged adult Dacus cucumis French were irradiated in nitrogen, following a 15 min exposure to an atmosphere of pure nitrogen, the degree of sterility induced by a given dose was less than that obtained with the same dose in air. To achieve sterility in males of approximately 98 per cent doses of 7 krad in air and 13 krad in nitrogen were required. With females, total sterility through infecundity was achieved by 6 krad in air and 13 krad in nitrogen. Based on the hatch of eggs from competitive mating tests, males receiving 14 krad in nitrogen were significantly more competitive than males given 9 krad in air. The optimal light intensity for mating of D. cucumis under artificial conditions was 16.2 1x. With this light intensity the mating propensity of males irradiated with 9 and 11 krad in air was significantly less than that of untreated males. The mating propensity of males given 14 krad in nitrogen approximated that of untreated males.
SUSCEPTIBILITY OF THREE STETHORUS SPP (COLEOPTERA: COCCINELLIDAE) TO SELECTED CHEMICALS USED IN N.S.W. APPLE ORCHARDS
Authors: Walters P. J. 
Published: April 2007

ABSTRACTThe contact susceptibility of Stethorus loxtoni, S. nigripes and S. vagans in the egg, larval and adult states to 27 chemicals was assessed. The chemicals tested at field concentration included insecticides, miticides, fungicides, chrbicides, chemical thinners and an antifeedant. Seven of these chemicals were highly toxic e.g., azinphos‐methyl, DDT, carbaryl, endosulfan, malathion, methidathion, tetrachlorvinphos, while twelve were non‐toxic e.g., vamidothion, Bacillus thuringiensis, Ryania, phenisobromolate, chlordimeform, cyclosuifyne, azaform, benomyl, captan, diuron, N.A.A., fentin hydroxide. The feasibility of these chemicals being used in an integrated control program is discussed.
ACTIVITY OF CHLORDIMEFORM AGAINST ORGANOCHLORINE RESISTANT AND SUSCEPTIBLE STRAINS OF HELIOTHIS SPP. (LEPIDOPTERA: NOCTUIDAE) FROM NEW SOUTH WALES
Authors: Clift A. D. 
Published: April 2007

ABSTRACTChlordimeform showed both ovicidal and larvicidal activity in the laboratory against eggs and first instar larvae of Heliothis armigera (Hübner) and H. punctigera Wallengren. H. armigera eggs were less susceptible than those of H. punctigera but there was no significant difference between the susceptible and resistant strains of H. armigera. There were no significant differences in susceptibility to chlordimeform between first instar larvae of the three strains.
PRESENCE OF A SEX ATTRACTANT PHEROMONE IN HELOPELTIS CLAVIFER (WALKER) (HETEROPTERA: MIRIDAE)
Authors: SMITH E. S. C. 
Published: April 2007

AbstractThe presence of a sex attractant pheromone in adult females of Helopeltis clavifer (Walker) was demonstrated in both laboratory and field trials. Pheromone release occurred at all times of the day, but the number of males attracted was greatest during the first few hours of darkness each day. Under field conditions, males were first attracted to four day old virgin females and continued to be attracted at intervals until the day before death.

ECLOSION AND OVIPOSITION RHYTHMS IN SIMULIUM ORNATIPES (DIPTERA: SIMULIIDAE)
Authors: HUNTER D. M. 
Published: April 2007

AbstractIn nature, adult Simulium ornatipes Skuse normally eclosed throughout the daylight period, but when water temperatures were high (≥26°), they eclosed mainly in the morning. Females usually eclosed slightly earlier than males. In the laboratory, daytime eclosion occurred under natural light and constant darkness but under constant white, purple‐pink and long ultraviolet light eclosion was arhythmic: these features are typical of circadian rhythms. Females oviposited throughout dark, cloudy days but on sunny, windless days they began ovipositing either when the sun decreased to a solar altitude of about 40 or when clouds covered the sun. These observations suggest that the oviposition period is related to light intensity.
FIELD OBSERVATIONS ON BEHAVIOUR OF A NORTH QUEENSLAND SPECIES OF PHYTALMIA (DIPTERA: TEPHRITIDAE)
Authors: Moulds M. S. 
Published: April 2007

AbstractThe spectacular lateral head projections in males of an undescribed species of Phytalmia function primarily as a means of contact between fighting pairs of males. Such fighting, which is often territorial in nature results in larger males dominating sexual activity. Following copulation the male remains with and guards the female until after what appears to be oviposition in decaying trunks of Dysoxylum decandrum, a rain forest tree.
LABORATORY REARING OF CULEX ANNULIROSTRIS SKUSE (DIPTERA: CULICIDAE)
Authors: McDonald G. , Smith I. R. , Shelden G. P. 
Published: April 2007

AbstractA successful technique was developed for laboratory rearing of Culex annulirostris. The larval rearing medium, containing water, crushed dog biscuit and yeast, required continuous aeration to prevent putrefaction. An emergence cage was designed to improve rearing and operational efficiency. Adults were fed on boiled sultanas, and females received their blood meals from guinea pigs. The culture room was kept at 26°C ± 1°C, and the relative humidity was alternated from 60% to 80% for three day periods to maximize reproduction and survival. Simulated dusk and dawn enhanced feeding and mating. Observations from culturing studies are reported.
PARASITISM OF OTHER ADULT DIPTERA BY TACHINIDAE IN AUSTRALIA
Authors: Ferrar P. 
Published: April 2007

AbstractAn earlier account of the tachinid Bactromyiella Mesnil parasitising adult Diptera is shown to be incorrect, the tachinid in question being actually a species of Hyalomyodes Townsend. Immature stages of Hyalomyodes sp. from Dasybasis Macquart (Tabanidae) and of a closely related tachinid from Amenia Robineau‐Desvoidy (Calliphoridae) are described and illustrated, and a relationship between these and an earlier reported parasite from Atherigona Rondani (Muscidae) is indicated. These examples provide the first authentic cases of Tachinidae parasitising adult Diptera.

AbstractThe life history of Anatrachyntis terminella (Walker) is described for the first time. Larvae of this moth infest the egg‐sacs of the spider Nephila edulis (Koch), feed on the eggs and pupate in the silk of the egg‐sac. The life history of the moth is discussed in relation to its effect on the spider.
THE EFFECT OF SEPARATION BY “PAPERING” ON CASTE RATIOS IN NASUTITERMES EXITIOSUS (HILL) (ISOPTERA)
Authors: McMahan Elizabeth A. , Watson J. A. L. 
Published: April 2007

AbstractThe separation by “papering” of Nasutitermes exitiosus from broken mound material provides a sample of termites containing higher proportions of small soldiers, second to fifth stage large workers, and alates, and lower proportions of larvae, first stage workers, presoldiers, and workers near to ecdysis, than occur in the termites that remain in the mound material. These differences can be correlated with differences in the behaviour of the various castes and stages when the nest is damaged.
CASTE RATIOS IN A LONG‐ESTABLISHED, NEOTENIC‐HEADED LABORATORY COLONY OF MASTOTERMES DARWINIENSIS FROGGATT (ISOPTERA)
Authors: Watson J. A. L. , Barrett R. A. , Abbey Hilda M. 
Published: April 2007

AbstractA colony of Mastotermes darwiniensis Froggatt, collected in the field in 1959 and maintained in the laboratory for 18 years, comprised approximately 8400 termites, plus 700 eggs in 40 pods. The colony was headed by 1 ♀ and 5 ♂ neotenics. The non‐reproductive castes included 5.7% soldiers plus presoldiers, 9.6% larvae, and nearly 85% workers. The pèrcentage of soldiers was similar to that in smaller laboratory colonies headed by primary reproductives.
