"An account is provided or attempts at biological control of arthropod pests in Australia. Ninety-eigth pests or groups of pests have been involved, totalling some 150 species, most of which are exotic. Some 70 were targetted in specific projects. The pests are listed alphabetically under Collembola (1), Hemiptera (56), Thysanoptera (1), Orthoptera (2), Coleoptera (9), Diptera (7), Lepidoptera (13), Hymenoptera (4), Acari (4) and Diplopoda (1). In additon to a summary table of results, a short dossier on each pest species or group provides (a) a precis of the autocomes, together with basic data on biology and pest status, (b) information on native natural enemies and (c) an account of the attempt(s) at biological control and the biology of the most important natural enemies. Without recent evaluations it is often not possible to assess accurately the level of successful control, but a general overvew indicates that about 30 of the target pests are verty well controlled and a further 20 are no loger important pests, indicating an overall a success rate for target pests of about two-thirds. With the exception of the dung-breeding bush fly, native pests have not proved susceptible to classical biological control." . . . . "Biological control organisms" . . "Australien" . .
