Various insect species display a uniform geometric increase in size during the larval stage (that is they follow the Brooks‐Dyar rule). Here, results of larval development are presented for the bunny‐tailed moth, Ochrogaster lunifer. The processionary larvae of this species live in a communal cohort, and moult en masse in the silken nest spun at the base of their host tree (usually a phyllodinous acacia). The exuviae, which remain buried in the accumulated silk and frass of the nest, provide a life history record of the larval cohort. Larval exuviae were collected from 773 cohorts at 37 localities in southeastern Queensland between November 1993 and May 1994. The 6,948 exuviae examined were from cohorts feeding on Acacia concurrens Pedley. Head‐capsules showed a strongly uniform geometric increase in size through eight larval instars, supporting the Brooks‐Dyar rule. The number of instars did not vary between trees or localities. A bimodal distribution of final instar head‐capsule widths was shown to be a sexual dimorphism, and similar bimodal distributions were found for instars V‐VII. Pupal size was also sexually dimorphic. The geometric size increase from one larval instar to the next holds for both males and the larger females. The geometric rule was tested using larval cohorts reared on A. concurrens in the greenhouse through instars I‐IV; development was remarkably similar to that in the field. Larval growth patterns of O. lunifer are very different from the structurally similar bag‐shelter moth. The ability to distinguish different instars of O. lunifer with a high degree of precision from field‐collected exuviae will allow accurate comparisons of development, survival and dispersal of larvae in different group sizes, on different trees and in different localities.

A redistribution program for N. capillatus in Tasmania was undertaken by direct transfer of live predators from established sites. Acceleration of the slow natural dispersal rate was facilitated by field vacuum collections being possible for 8 months/year, excluding winter and early spring when active stages of N. capillatus were in low numbers or absent. Intermittent collections, mostly between October 1992 and May 1995, resulted in the release of 933,600 N. capillatus into 494 Tasmanian dairy pastures. The predator established at about 90% of these sites. Establishment of the predator on every dairy farm in Tasmania on which S. viridis is a pest is considered a relatively easy short‐term procedure.

A simple sticky‐trap method suitable for estimating the abundance of Srninthurus viridis on annual medic pastures was developed and compared to a standard coring method. The sticky‐trap was developed for sampling in newly established medic pastures when cores cannot be removed intact due to insufficient plant material, particularly on dry or sandy soils. This method provides a quick estimate of S. viridis population density in the field.

Infestations of Oryzaephilus surinamensis, sawtoothed grain beetle, from consolidated off‐farm grain bulks in New South Wales were monitored for resistance to organophosphorus grain protectants by impregnated filter paper tests. Resistance to fenitrothion, pirimiphos‐methyl or chlorpyrifos‐methyl was detected in 95%, 95% and 67% of the infestations, and maximum resistance factors compared with a susceptible strain were 85, 55 and 32 times, respectively. Most strains were either resistant to all three insecticides or were resistant to fenitrothion and pirimiphos‐methyl only. Grain treated initially with chlorpyrifos‐methyl 10 mg/kg suppressed strains with strong resistance to fenitrothion or chlorpyrifos‐methyl by >90% after 4 months aging. The usefulness of chlorpyrifos‐methyl in a control strategy for effective grain protection is discussed.

The roles of detailed taxonomic interpretation in insect surveys are discussed, with emphasis on rapid biodiversity assessment, the levels of focus or penetration needed in particular contexts, and optimising the use of limited taxonomist expertise and resources. Quality control necessitates taxonomic accuracy and precision, and approaches to increasing these are noted. The complementary roles of taxonomists and ecologists in undertaking and analysing insect surveys are outlined, and a practical agenda linking their expertise is suggested as a means of improving capability in insect surveys for practical conservation.

The food sources of cave‐dwelling insects are difficult to document, and those of root‐feeding cixiid nymphs (Hemiptera: Cixiidae) particularly so because of their tendency to jump from their substrates upon the slightest disturbance. By histologically staining the stylet sheath left by Oliarus sp. feeding on Ficus roots, we establish the host association beyond doubt. Histological sections also demonstrate that Oliarus feeds in the cells of the endoderm and within the xylem vessels. The technique we describe can be used to determine host relationships for cave‐dwelling Cixiidae in general, providing an additional angle for the study of the evolutionary history of cave adaptation in this group.

The level of resistance to the sorghum midge, Contarinia sorghicola, in a range of grain sorghum hybrids was assessed: in the laboratory, by measuring oviposition (eggs/spikelet and % spikelets infested); in the glasshouse, by measuring oviposition and seed set; and in the field, by measuring panicle weight loss per ovipositing female per day. The levels of oviposition and seed set determined in the laboratory and glasshouse trials were significantly correlated with the field parameter. Number of eggs per spikelet was the laboratory parameter most highly correlated with the field result (r = 0.93, P < 0.01). Studies on the rate of oviposition under the conditions of the bioassay confirmed 6 h as an appropriate interval to expose panicles to midges. A laboratory method based on estimating the number of eggs produced by 5 midge females on 50 flowering spikelets in 6 h at 25°C and 75%orh is suggested as a practical method of testing for level of resistance in those sorghum hybrids showing ovipositional antixenosis.

During a project to detect and evaluate potential biological control agents for the submersed aquatic weed, hydrilla (Hydrilla verticillata), the distribution, abundance and field host‐range of a recently described aquatic fly, Hydrellia balciunasi were studied in Australia from 1985‐1992. A total of 17,729 specimens were collected at 55 sites in Queensland, New South Wales and the Northern Territory. H. balciunasi was found to be relatively common, being collected in 57% of 550 collections of hydrilla. Although larvae were collected from 17 aquatic plant species, hydrilla was the preferred host for this fly, with 97% of the specimens collected from it. Based on these field data, H. balciunasi was exported to quarantine in the United States of America in 1988 for laboratory evaluation of its host‐range. Quarantine studies confirmed its safety as a biological control agent, allowing its release in the field in Florida in 1989. This is the first endemic Australian insect released as a biological control agent for a weed in the U.S.A.

Snow‐melt pools at a number of localities in the upper altitudes of the Kosciusko National Park were searched for mosquito larvae during October through December 1994. The only species found in pools above 1,600 m was Aedes (Ochlerotatus) nivalis Edwards. Dry‐ice‐baited light traps were used to sample adult mosquitoes in the same areas but no Aedes species other than Ae. nivalis were collected. Both larvae and adults showed minor morphological variation from published descriptions.
