DEVELOPMENTAL TIME OF CREONTIADES DILUTUS (STÅL) (HEMIPTERA: MIRIDAE) IN RELATION TO TEMPERATURE
Authors: Foley D. H. , Pyke B. A. 
Published: April 2007

AbstractThe developmental time of the green mirid Creontiades dilutus (Stål) reared on green bean was examined in relation to 5 temperatures ranging from 19 to 31 ± 1 °C. Using thermal summation and a threshold temperature of 12.3 °C, 280 day‐degrees was estimated for development from egg to adult.
PREDATORS OF OMMATOIULUS MORELETII (LUCAS) (DIPLOPODA: IULIDAE) IN PORTUGAL AND AUSTRALIA
Authors: Baker G. H. 
Published: April 2007

AbstractThe Portuguese millipede Ommatoiulus moreletii (Lucas) is an introduced pest in southern Australia. A variety of predators (including spiders, centipedes, carabid and staphylinid beetles, reptiles and mammals) were found in Portugal, and fed upon O. moreletii in the laboratory. Few predators were found in South Australia which accepted the millipede as prey. The beetle Staphylinus olens Müller and the hedgehog Erinaceus europaeus L., both of which are common in Portugal, were particularly voracious. In the field, unidentified predators caused significant mortality of O. moreletii in Portugal but not in Australia. It is inferred that the greater abundance of O. moreletii in Australia compared with Portugal is due in part to a lack of effective predators.
PECTINOPHORA SCUTIGERA (HOLDAWAY) (LEPIDOPTERA: GELECHIIDAE): MONITORING POPULATIONS AND DISRUPTING SEXUAL COMMUNICATION WITH Z, Z‐ AND Z, E‐ 7, 11–16: AC IN THE FIELD
Authors: Flint H. M. , Stone M. 
Published: April 2007

AbstractSex attractants were tested for monitoring of populations and disruption of sexual communication of the pinkspotted bollworm, Pectinophora scutigera (Holdaway), in cotton at Biloela, Queensland. A 9:1 mixture of Z, Z‐ to Z, E–7, 11‐hexadecadien‐1‐ol acetate (7, 11–16: Ac) captured significantly more male moths than the Z, Z‐ isomer only (1 mg baits in Delta traps). Treatment of 0.1 ha field plots with Z, E‐ 7, 11–16: Ac significantly altered response of males to mixtures of Z, Z‐ and Z, E‐ 7, 11–16: Ac from 9:1 to 1:1 and 1:3 mixtures. Treatment with Z, Z‐ 7, 11–16: Ac did not alter male preference for the 9:1 mixture. Both the 9:1 mixture of Z, Z‐ to Z, E‐ 7, 11–16: Ac and Z, Z‐ 7, 11–16: Ac caused 95–100% disruption of trap catch (traps baited with 1 mg of the 9:1 mixture) in 0.1 ha field plots treated at a rate of 7.2 g AI/ha.

NATURAL OCCURRENCE OF INSECT PATHOGENIC NEMATODES (STEINERNEMATIDAE AND HETERORHABDITIDAE) IN SOIL IN AUSTRALIA
Authors: Akhurst R. J. , Bedding R. A. 
Published: April 2007

AbstractIn a number of surveys using baiting techniques, entomogenous nematodes of the families Heterorhabditidae and Steinernematidae were detected in all states and territories of Australia. At least 4 Heterorhabditis species (3 previously unknown), 6 Steinernema species (4 previously unknown) and one species of an undescribed genus of Steinernematidae were found. In Tasmania, where collections were made over 10 years, the nematodes were detected more commonly in winter‐spring than in summer‐autumn; there was no significant difference in their occurrence in forest from that in grassland.

CYTOGENETIC AND CROSSBREEDING EVIDENCE FOR ADDITIONAL CRYPTIC SPECIES IN THE ANO PHELES ANNULIPES WALKER COMPLEX (DIPTERA: CULICIDAE)
Authors: Booth D. R. , Bryan Joan H. 
Published: April 2007

AbstractPopulations of Anopheles annulipes Walker s. 1. from eastern and northern Australia were studied by crossing to a laboratory colony (Standard) and, in some cases, to each other. The resulting adult females had normal reproductive systems. Some of the crosses produced males with reduced testes. Extensive asynapsis, with or without banding sequence differences in the polytene chromosomes, characterised many of the progeny of the crosses. Four new X chromosomes were revealed and are illustrated. Rearing parameters showed evidence of genetic incompatibility between the chromosomal types. Duration of copulation was also found to vary. The evidence presented in this paper suggests that the taxon is a complex of up to 10 species.

EFFECT OF DROUGHT AND GRASSHOPPERS ON ESTABLISHMENT OF DIALECTICA SCALARIELLA (ZELLER) (LEPIDOPTERA: GRACILLARIIDAE), A POTENTIAL BIOLOGICAL CONTROL AGENT FOR ECHIUM PLANTAGINEUM L.
Authors: Delfosse Ernest S. , Lewis Robert C. , Smith Carey S. 
Published: April 2007

AbstractThe leaf‐mining moth, Dialectica scalariella, a potential biological control agent for Echium plantagineum, was released at 3 sites in New South Wales in winter 1980. Larvae in leaves of laboratory‐infested plants survived in the field despite sub‐zero temperatures. No D. scalariella were found at 2 of the sites subsequently. A population of D. scalariella was developing at the third site, but severe drought and attack by grasshoppers destroyed the Echium population and prevented establishment. A High Court injunction imposed on the program in July 1980 prevented further releases.
DIURNAL OVIPOSITION ACTIVITY IN GRAIN SORGHUM BY CONTARINIA SORGHICOLA (COQUILLETT) (DIPTERA: CECIDOMYIIDAE)
Authors: Modini M. P. , Page F. D. , Franzmann B. A. 
Published: April 2007

AbstractDiurnal oviposition activity and preference for panicles at various stages of anthesis by female sorghum midge, Contarinia sorghicola, were investigated on grain sorghum in central and southern Queensland during 1981–82. Peak activity was recorded between 0800 h and 1100 h, the time of maximum midge numbers being slightly modified by daily temperature. Ovipositing midges preferred panicles at mid‐anthesis, while panicles prior to and finishing anthesis were the least attractive. We define criteria for optimum pest population assessment.

AbstractThe 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.
REPRODUCTIVE DIAPAUSE IN TYPHLODROMUS OCCIDENTALIS NESBITT (ACARINA: PHYTOSEIIDAE) FROM SOUTHERN NEW SOUTH WALES
Authors: James David G. 
Published: April 2007

AbstractStudies on the reproductive diapause of an introduced insecticide‐resistant strain of the phytoseiid predator, Typhlodromus occidentalis Nesbitt, from southern New South Wales are reported. Diapause was induced in 43–59% of predators when reared at 16 or 19°C under photophases of 10–12 h. No diapause induction response curve with changing photophase was evident. Diapause in overwintering predators was readily terminated by exposure to warm temperatures and a long photophase. The rapidity of diapause termination increased progressively during winter. The apparent loss of dependency upon reproductive diapause as an overwintering strategy in this strain of T. occidentalis is discussed.
THREE NEW SPECIES OF POLISTES LATREILLE (HYMENOPTERA: VESPIDAE) FROM PAPUA NEW GUINEA, WITH NOTES ON THE TAXONOMIC STATUS OF THE SUBGENUS STENOPOLISTES VAN DER VECHT
Authors: Kojima J. , Kojima K. 
Published: April 2007

AbstractThree new species of Polistes Latreille are described from Papua New Guinea. Of these, P. occultus sp. n. largely fits the diagnosis of the subgenus Stenopolistes van der Vecht. However, while P. watutus sp. n. and P. medius sp. n. have the jugal lobe of the hind wing defined by a wide incision (an apomorphic character of Stenopolistes), in the other characters distinguishing Stenopolistes and the subgenus Polistella Ashmead have states typical of Polistella. If Stenopolistes is regarded as a subgenus, then Polistella is defined only by a symplesiomorphy, thus Stenopolistes must be synonymised under Polistella.

INFLUENCE OF WEATHER ON TRAP CATCHES OF CHRYSOMYA RUFIFACIES (MACQUART) (DIPTERA: CALLIPHORIDAE)
Authors: Vogt W. G. 
Published: April 2007

AbstractAdult populations of the hairy maggot blowfly, Chrysomya rufifacies were sampled 6 times daily between dawn and dusk on 35 occasions during 1984/85 at Murrumbateman, New South Wales, using wind‐oriented fly traps. Temperature, solar radiation and relative humidity explained 74.3, 8.8 and 1.6% of the within‐day deviance of catches. Flies did not enter traps unless the temperature exceeded 13°C. Above 13°C, log catch increased linearly up to 23°C and remained constant thereafter up to the maximum temperature recorded (37°C). Catch rates were unaffected either by wind speed or time of day. Weather effects also explained 87.5% of the between‐day variation in daily catches. Standardized catches of C. rufifacies indicate that at Murrumbateman, C. rufifacies numbers peak in autumn and that unstandardized data may not truly reflect seasonal changes in fly numbers.
TRAP CATCHES OF MUSCA VETUSTISSIMA WALKER (DIPTERA: MUSCIDAE) AND OTHER ARTHROPODS ASSOCIATED WITH CATTLE DUNG IN RELATION TO HEIGHT ABOVE GROUND LEVEL
Authors: Vogt W. G. 
Published: April 2007

AbstractCatches of male and female Musca vetustissima in isolated fly traps located up to 3 m above ground were inversely related to height, but sex ratios and female age‐distributions were similar for catches at all heights. Since the effect of height on log catch was highly significant, traps must be operated at a standard height to obtain estimates of fly abundance that are comparable between sampling occasions. Seasonal variation in log catch in relation to height was also highly significant, but was small in comparison to the effects of height. Catches of other dung‐frequenting arthropods in pitfall traps were highest at ground level. Very few arthropods were caught in traps located 2 m or more above ground.
LOW LEVEL FLIGHT ACTIVITY OF NESOCLUTHA PALLIDA (EVANS), OROSIUS ARGENTATUS (EVANS) AND ZYGINA ZEALANDICA (MYERS) (HEMIPTERA: CICADELLIDAE) IN SOUTHERN VICTORIA
Authors: Hosking J. R. , Danthanarayana W. 
Published: April 2007

AbstractLow level flight activity of three cicadellids, Nesoclutha pallida, Orosius argentatus and Zygina zealandica was determined by using suction traps located at La Trobe University (Melbourne) and Toolangi (60 km NE of Melbourne). The lower temperature thresholds for flight were 17.0°C for Z. zealandica, and about 21.5°C for both N. pallida and O. argentatus. Upper temperature thresholds for flight of N. pallida, O. argentatus and Z. zealandica were about 34.2°C, 37.2°C and 31.2°C respectively. Below 4.12 m wind speeds were also found to affect flight activity, wind speeds below 1.0m s−1 being less satisfactory than higher wind speeds, while at wind speeds above 6.1 m s−1 no flights occurred. All species showed a diurnal periodicity, peaks of activity occurring at sunset and sunrise for Z. zealandica and at sunset for N. pallida and O. argentatus. Between 0.38 m and 4.12 m above ground level, density of N. pallida, O. argentatus and Z. zealandica diminished regularly with increasing height; average values for Λ (regression coefficient of log density on log height), based on weekly observations, were ‐0.81 for N. pallida, ‐0.55 for O. argentatus and ‐1.19 for Z. zealandica.
FECUNDITY, LONGEVITY AND OVERWINTERING OF TRISSOLCUS BIPRORULI GIRAULT (HYMENOPTERA: SCELIONIDAE) A PARASITOID OF BIPRORULUS BIBAX BREDDIN (HEMIPTERA: PENTATOMIDAE)
Authors: James David G. 
Published: April 2007

AbstractInformation is presented on the fecundity, longevity and overwintering of Trissolcus biproruli Girault a parasitoid of Biprorulus bibax Breddin (spined citrus bug) in inland citrus growing areas of New South Wales and Victoria. Virgin and mated females produced 58.2 and 98.0 progeny during adult life‐times of 24.2 and 19.7 days, respectively. The bulk of offspring was produced during the first few days of adult life. Males and females supplied with food maintained without hosts lived for 30.2 and 26.4 days, respectively. Unfed parasitoids died within 4 days. Low temperatures and short photoperiods did not induce reproductive diapause in developing or teneral parasitoids. During winter, females were capable of oviposition provided sunlight was available. Adult parasitoids successfully overwintered when provided with food.
ASPECTS OF THE BIOLOGY OF THE PRIMITIVE ANT GENUS MYRMECIA F. (HYMENOPTERA: FORMICIDAE)
Authors: Crosland M. W. J. , Crozier R. H. , Jefferson E. 
Published: April 2007

AbstractUnlike some other primitive ants, workers of at least 4 species of Myrmecia are unable to independently eclose from their cocoons. Workers of some Myrmecia species have large functional ovaries and a spermatheca. Workers of such species lay trophic eggs. In other Myrmecia species the workers have reduced ovaries and trophallaxis occurs by oral regurgitation. A Myrmecia nuptial flight is described and a brief description is given of a Myrmecia ergatandromorph.

EVIDENCE FOR ABSORPOTION OF EUCALYPT ESSENTIAL OILS BY PAROPSZS ATOMARZA OLIVIER (COLEOPTERA. CHRYSOMELIDAE)
Authors: Ohmart Clifford P. , Larsson Stig 
Published: April 2007

AbstractA terpenoid budget was constructed for Paropsis atomariu (Olivier) feeding on Eucalyptus blakelyi Maiden leaves to determine if larvae absorbed leaf terpenoids. Groups of larvae were fed leaves which contained a range of terpenoid concentrations (1–7.9%). The amounts of terpenoids consumed and excreted by each group were determined. Calculation of the ‘expected’ concentration of terpenoids in the excreta was calculated based on the digestive efficiency of each larval group and the assumption that terpenoids passed unaffected through the digestive system.Comparisons of the amounts of terpenoids excreted with amounts expected if no absorption occurred showed that larvae absorbed a major proportion of ingested terpenoids. Larvae absorbed, or otherwise converted to other compounds, 86% of ingested cineole, a component which commonly makes up more than 75% of the total terpenoids in E. blakelyi. Analyses of larval tissue showed that leaf terpenoids were not present and therefore not sequestered. It is suggested that larvae metabolise leaf terpenoids.

THE POTENTIAL OF METARHIZIUM ANISOPLIAE (METSCHIKOFF) SOROKIN (DEUTEROMYCOTINA: HYPHOMYCETES) AS A BIOLOGICAL CONTROL AGENT OF INOPUS RUBRICEPS (MACQUART) (DIPTERA: STRATIOMYIDAE)
Authors: Samuels K. D. Z. , Pinnock D. E. , Allsopp P. G. 
Published: April 2007

AbstractIsolates of the entomopathogenic fungus Metarhizium anisopliae were bioassayed against larvae of Inopus rubriceps Where spore concentration was high (6.7 × 105‐6.7 × 1 06 spores/g of soil) all isolates were pathogenic At lower concentration (6.7 × 104 sores/g soil), pathogenicity varied significantly between isolates, as did their ability to grow and sporulate on the larval cadaver followng internal colonisation There was variation in the campatibility of M. anisopliae isolates with pesticides used on sugarcane, but certain isolates were highly compatible. Although some of the isolates of M. anisopliae were highly pathogenic and highly compatible with the pesticides tested, strain improvement to enhance epizootic potential may be appropriate. M. anisopliae has the potential to be an effective biological control agent of I. rubriceps.
