CAMPBELL, A.J., BOWMAN, G., DOMINIAK, B.C., BARCHIA, I.M. and MUDFORD, E.M. Comparison of loose and bagged eclosion methods of varying pupal densities for the production of adult sterile Queensland fruit fly Bactrocera tryoni (Froggatt) (Diptera: Tephritidae) pupae. ……………………………. 7
Holding dyed sterile pupae of Queensland fruit fly (Bactrocera tryoni) (Qfly) for adult eclosion loose in open tubs has produced variable results. We compared the effect of holding pupae loose and in mesh bags in tubs for a range of densities. Only at low density levels (10000 and 20000 per bag) was eclosion significantly higher for bagged, than loose pupae. Similarly eclosion of viable adults (those which successfully left the puparium) showed a similar trend, with differences between the methods only significant at densities <= 30000 pupae. We conclude that adult eclosion for the sterile Qfly could be optimised by reducing the density of pupae per rearing tub and by allowing flies to emerge from pupae held in mesh bags.

DOMINIAK, B.C., GIPPESPIE, P.S., WORSLEY, P. and LÖCKER, H. Survey for sycamore lace bug, Corythucha ciliata (Say) (Hemiptera: Tingidae) in New South Wales during 2007. …………………………………………… 27
A state-wide search for the exotic plane tree pest sycamore lace bug was undertaken in New South Wales during 2007. Sycamore lace bugs were found in the Sydney basin but not in other parts of the State. There were 78 site inspections with 43 positive detections.

FLETCHER, M.J. An impressive new species of Euacanthella Evans from Western Australia (Hemiptera: Cicadellidae: Euacanthellinae). ……………………………………………………… 15
The new species Euacanthella impressa sp. nov. (Hemiptera: Cicadellidae: Euacanthellinae) is described from Barrow Island and Loma Glen Station in Western Australia. The species is distinctive because of the huge ovipositor which makes up about one third of the body length of the adult female.

LEVOT, G.W. Feasibility of in-hive control of adult small hive beetles Aethina tumida Murray (Coleoptera: Nitidulidae)with an insecticide treated refuge trap. ………………………………………………. 21
The significant impact of small hive beetle on the profitability of bee keeping in eastern Australia prompted research into the use of insecticidal traps for deployment in beetle infested hives. A prototype refuge trap comprising foil-covered fipronil-treated corrugated cardboard achieved up to 100% control of adult beetles in field efficacy trials conducted in western Sydney apiaries. Although demonstrating the feasibility of using such a refuge trap against beetle infestations damage to some traps by resident bees and resultant bee deaths highlighted the need for a more robust cover for the insecticide-treated cardboard insert.

STEVENS, M.M., MCDONALD, F.J.D., WARREN, G.N. and MO, J. Pentatomidae (Hemiptera) associated with rice crops in southeastern Australia. ………………………………………. 1
In response to reports of blemished grain in export shipments of Australian rice a sweep-net survey of stink bugs (Hemiptera: Pentatomidae) was conducted across 38 rice crops in the Murrumbidgee and Murray Valleys during the 2005/6 and 2006/7 rice seasons. Seven stink bug species were recorded, however three species, represented in the samples by both adults and nymphs, accounted for approximately 97% of the 257 stink bugs collected. Anaxilaus vesiculosus (Herrich-Schaeffer) dominated the fauna (84%), whilst Eysarcoris trimaculatus (Distant) and Nezara viridula (L.) constituted 9% and 4% of captures respectively. Although stink bug densities were very low and unlikely to cause significant damage to the crops examined, there was a high level of variability between crops and also between seasons, with a six-fold increase in the average number of bugs collected per crop in the second year of the study. Field-collected A. vesiculosus adults placed on a caged rice plant survived for up to 20 days. Nymphs that emerged from eggs laid on the plant were reared through to adulthood without any alternative food sources being supplied. Hulled grain from the exposed plant showed the characteristic blemishes associated with stink bug feeding. This is the first record of A. vesiculosus feeding and developing on rice.

STRID, G.S.M. Mosquitoes (Diptera: Culicidae) of City of Ryde, New South Wales ……………………………………….. 37
The City of Ryde local government conducted field collections of larval and adult mosquito populations between the seasons 1992-93 and 2007-08 to assist mosquito management strategics. A total of 25 species was recorded. The two most commonly occurring and abundant species in the area were the saltmarsh mosquito Aedes vigilax (Skuse) and freshwater mosquito Aedes notoscriptus (Skuse). Both species have the potential to cause nuisance-biting and public health impacts but differ substantially in their ecology and management response requirements.

WEBB, C.E. and RUSSELL, R.C. Mosquitoes of Centennial Park, Sydney. ……………………………………… 31
A short survey of the mosquito populations within Centennial Park, Sydney, was undertaken between January and April 2006. Dry-ice baited light traps were used to sample the host seeking adult mosquito populations and surveys of aquatic habitats within the parklands were undertaken for immature mosquitoes. A total of eight species was collected but, despite extensive aquatic habitats (e.g. ponds, creeks), the overall numbers of mosquitoes were relatively low. The most abundant species was Aedes notoscriptus (Skuse), a mosquito closely associated with small water holding containers and tree holes. The nuisance-biting and public health risks of the mosquito populations associated with the parklands are low.
