“…While Agrypnus sp. are significant pests in Queensland and New South Wales (McDougall 1934;Goodyer 1983;Forrester et al 1984), they are also reported as predators of pest insects in pasture (Robertson et al 1981;Robertson 1987). Predation of Helicoverpa spp.…”

“…Cultivation of fields before moths emerge from overLbintering pupae in the spring has been recommended as a management tactic (Wilson 1987;Fitt and Daly 1988). Since the development of pyrethroid resistance in populations of H. armigera (Gunning et al 1984; Daly and Murray 1988), greater emphasis has been placed on this practice. High frequencies of resistance are found in overwintering H. armigera under cotton crops, and these may maintain resistance in local populations (Daly and Fitt 1990).…”

The spatial disrribution and mortaliry of H e k o i w p n pitncrigfm (R'allsngren) and H . armfgera (Hubner) pupas \\ere in\estigated under field crops on the Darling Downs, Quernsland. %lean pupal depth was 47.3 rnm for H . pirnc.rigtm and 46.2 nim for H . anvigerc?. For each species, the mean depth of male pupae was significanrly greater than that of female pupae. In rain-gro1r.n crops \vhere distincr ridges were nor formed for rhe planr rows, pupae \\ere evenly distributed across the inter-row space. Average pupal survival \\-as 36.6"o (range 11 .8-70.2). Parasit ism averaged 37.0% (range 8.2-61.9). Se\ en primary parasitoids and four hyperparasitoids were recorded from pupae. Predarion by .4gr!p/iits sp. lanae ivas recorded under sorshum. hlore intensive sampling of nondiapausing, over\\ intering and spring diapausing pupal populations are ivarranted to further in\estigate mortality factors.

“…Both chlorpyrifos and terbufos increased establishment in some trials but appeared to be phytotoxic in others. Thomson (1979) regards both insecticides as non-phytotoxic when used at recommended rates, and Forrester et al (1984) found no evidence of phytotoxicity and reported good control of A . variubilis on maize.…”

Field trials at 5 sites in southern Queensland were used to determine the effectiveness of soil compaction with a press wheel and various methods of application of 4 insecticides for the control of soil insect pests of sorghum and sunflower seeds and seedlings. The pests involved were black field earwigs, Nala lividipes (Dufour), sugarcane wireworms, Agrypnus variabilis (Candeze), seedharvesting ants (Pheidole sp. and an unidentified species), and false wireworms. Pterohelaeus alternutus Pascoe, P. darlingensis Carter. Gonocephalum marleayi (Blackburn). Crstrinus trivialis Erichson.Some of the techniques of insecticide application improved establishment at 4 of the sites. Heptachlor was the most effective insecticide overall and caused no phytotoxicity to either crop. Chlorpyrifos and terbufos had apparent phytotoxic effects in some trials. Carbaryl which was applied only by water injection, was less effective than heptachlor and (sometimes) chlorpyrifos.Where insecticides caused no apparent phytotoxicity, applications by seed dressing, presoaking, water injection, and in-furrow spray generally were equally effective in improving establishment. Seed dressing and presoaking required less active ingredient and were the most e&cient ways of applying insecticide.Soil compaction with a press wheel also significantly increased establishment. at all sites for sunflower and at 4 sites for sorghum. Response to compaction by the press wheel at 2 sites was attributed solely to insect control as soil water was adequate and control plots had extensive insect damage and low emergence.

“…They are described as omnivorous, feeding on both plant roots and other insects (Robertson et al 1981). C. exsul in Hawaii and A. variabilis in Queensland are pests offield crops, especially sugar cane, and each has been referred to in thos~ regions by the common name of sugar cane wIreworm (Williams 1931;McDougall 1934b;Forrester et al 1984). In New Zealand they cause some damage to seedling maize (East & Watson 1978), but most attention has been given to their role as predators, particularly on larvae of Inopus rubriceps (Macquart), the Australian soldier fly (Robertson & Pottinger 1979;Robertson et al 1981).…”
