Bluesoxiphu rugg was recorded parasitising both sexes of the bushcricket, Sciurusuga quadrutu, at Cape Naturaliste in Western Australia. This is the first host record for B. rugg. Parasitism rates recorded over three successive seasons ranged from 0 to 11.1%. Parasite development within the host was 6 d. Parasitised male S. quudrutu were frequently multiparasitised with the ormiine tachinid fly Homotrixu alleni Barraclough. From 6 to 24 B. rugg developed in each host, with pupal size significantly affected by the number of larvae per host. The duration of the pupal stage at 15‐25 °C ranged from 13 to 35 d. The sex ratio of emerged flies was 50:50. The previously unknown adult female fly and third‐instar larva of B. rugg are described.

The Australian species of Glyptotermes Froggatt are revised and two new species, G. barretti and G. finniganensis, from Cape York Peninsula, Queensland, are described. The following new synonymy is proposed: G. eucalypti Froggatt (=G. neotuberculatus (Hill)). The revision was based on a morphometric analysis of all available full series collections of Glyptotermes spp. held in Australian institutions. In addition to the above, the Australian species include G. brevicornis Froggatt, G. iridipennis Froggatt and G. tuberculatus Froggatt. Keys to the alate and soldier castes of the six Australian species now included in Glyptotermes are provided.

Two field collected strains of western flower thrips, Frankliniella occidentalis, were tested against proprietary and experimental formulations of insecticide. Thrips were tested using a novel method whereby thrips were confined in testing units throughout all stages of the bioassay procedure. The bioassay technique proved to be quick and robust. Of the chemicals tested, the two non‐registered compounds chlorfenopyr and fipronil were most active against field‐collected F. occidentalis. The field‐collected strains were tolerant to a range of organophosphate, carbamate and pyrethroid chemicals. Comparisons of dose‐response curves with established field‐use‐rates indicate that only methiocarb and methamidophos are likely to be completely effective in the field. The theoretical implications of the data for management of F. occidentalis in Australia is discussed.

A synopsis of Old World ormiine systematics and biology is given. Homotrixa Villeneuve is differentiated from all four other Old World genera of Ormiini. The generic identity of Homotrixa is discussed. Both sexes of two new species of Homotrixa from southwestern Australia are described, keyed and figured, namely Homotrixa alleni Barraclough sp.n. and H. hirsuta Barraclough sp.n. The puparium of H. alleni is also described. These are the first species of Homotrixa to be described from Australasia; the genus is otherwise known only from the type locality of the type species in Taiwan. Further species of Homotrixa from northern Western Australia, the Northern Territory, Queensland, New South Wales and the Australian Capital Territory remain undescribed. The genus appears not to occur south of 36 °s in Australia. Recorded hosts of H. alleni include three species of Tettigoniidae: Sciarasaga quadrata Rentz, Mygalopsis pauperculus (Walker) and Pachysaga croceopteryx Rentz.

MITcHELL Watt, D. Hales
The cotton aphid, Aphis gossypii Glover, is a polyphagous aphid that is a pest on a wide range of commercially important crops. It sometimes gives birth to small yellow offspring that grow to be only about 1/2 to 1/3 of the typicaladult weight. These “yellow dwarfs” differ from the typical form in their small size, by having 5 instead of 6 antennal segments, and by never attaining dark greedblack coloration; they are considered to be a separate developmentally‐programmed morph. A morphometric description of the yellow dwarf form is provided. Yellow dwarfs develop at a slower rate than typical aphids and have a lower intrinsic rate of increase. An orthogonal experiment demonstrated that production of yellow dwarfs can be induced by presumed less‐suitable host‐plant species at temperatures of 15 ° and 25 °, but not 20 °C. Crowding may also induce birth of yellow dwarfs. Possible advantages of the yellow dwarf developmental pathway are discussed.

Native plants from remnant strip vegetation at roadside sites near Keith, South Australia were monitored during the period when leafcutting bees, Megachile rotundata, were managed on nearby lucerne crops. The predominant native plants flowering at sampling sites during the November to March period included Melaleuca uncinata, Melaleuca lanceobta, Baeckia behrii and Bursaria spinosa. No M. rotundata were found on native vegetation. No M. rotundata prepupae were found in 12 microdomiciles placed in a nearby Conservation Park. The results of the monitoring program suggested feral leafcutting bee populations were unlikely to have established in significant numbers and the impact on the local plants and animals was negligible.

Culicoides molestus larvae inhabiting canal estate beaches in the Tweed Valley, New South Wales, were infected by the fungus Lagenidium giganteum during 1994. This is the first record of a pathogen infecting C. molestus. The monthly average infection at four sites ranged from 33% to 1.2%. At one site, Endless Summer, epizootics were recorded in August and November with 100% and 62% infection, respectively. with the water adjacent to the canal beach having a salinity of over 30 ppt NaC1.

Antibiotics on the surface of ants inhibit pathogenic microorganisms and significantly lower pollen viability. However, the viability of pollen in contact with the integument of Apis mellifera L. and Vespula germanica (F.) is not significantly lowered. Trigona carbonaria Smith induces some reduction in pollen viability and this may be the effect of resins harvested for nest construction. The disruption of pollen function by T. carbonaria is much less severe than that produced by ants. Differential integumental effects on pollen are consistent with the relative abundance of bee, wasp and ant pollination systems, particularly the extreme rarity of pollination by ants.
