“…A third method of avoidance, applicable to endoparasitoids, is the placement of the egg by the parasitoid in select tissues where the egg hatches to develop out of reach of the immunocompetent hemolymph system [114,115]. For example, Klomp and Teerink [116] reported that two parasitoid diptera and one ichneumonid, all parasitic on the pine looper Bupulus piniurius, develop between the cuticular intima or peritrophic membrane and the epithelium of the digestive system, thus avoiding the immune system. Another example, provided by Silvestri [117], is where the eggs of Plufygustes dryomyiue deposited in host ganglia develop, but are rapidly encapsulated when placed in the host body cavity.…”

Insects have evolved many mechanisms that reduce their potential for serving as hosts for entomophagous species. Some of these mechanisms involve escape, mimicry, and repellancy, which are effective defense mechanisms against both predators and parasitoids. But, insects have a second line of defense against parasitoids and parasites. These may include repellancy and a cuticular barrier to invasion but they include several internal defenses that are collectively referred to as immune mechanisms. The current understanding of insect immunity is reviewed as background to examining the ways in which insect parasitoids have evolved to successfully handle the immune system of the host. The various means that parasitoids utilize to handle the insect immune systems have been divided into five approaches. These five approaches are described and current knowledge of the mechanisms used by parasitoids to deal with the immune system of their host is explored.

“…These usually have a single generation per year. A number of other species overwinter as first instar larvae in the fatty tissue of the host pupae (Klomp & Teerink, 1978). These are often bivoltine and many require a different host species in the spring and autumnal generations ( van Veen, 1981) whilst some species may even have two generations in a single host generation.…”

Illustrated keys are given to the 22 subfamilies and 215 genera of ichneumonids occurring in Australia. Four subfamilies (Lycorininae, Orthocentrinae, Oxytorinae and Phrudinae) are newly recorded from the continent as are six tribes, 80 genera and subgenera and 11 species. One new tribe, the Ankylophonini, is proposed in the Tryphoninae and 44 genera and 55 species are described as new. Eleven new combinations and 13 new synonyms. are proposed. The name Delopia Cameron is re-instated for the large genus previously known as Dusona Cameron, and Dusona is limited to a small New Zealand species-group. One replacement name for a junior homonym is proposed. For each subfamily a diagnosis is given together with brief distributional and biological notes. Under each genus is listed a full synonymy, brief diagnosis (which may be expanded if the generic limits have been altered), list of Australian species and the known hosts. Introductory sections include notes on nomenclature, terminology and relationships, an extensive account of ichneumonid biology, a history of ichneumonid work in Australia and an account of the relationships and characteristics of the Australian fauna. The work is completed by a check-list of Australian ichneumonids, an extensive bibliography and indexes to both ichneumonids and their hosts.The Ichneumonidae of Australia delineate subspecies. The use of very few characters for delimiting subspecies of Inda-Australian ichneumonids appears suspiciously like editing the available data to fit one's preconceived ideas.Fourthly, many of the 'subspecific characters' do not work when additional material is examined. Not infrequently one can find a typical example of one subspecies in the wrong area (Gauld, 1976c). In some cases the geographical ranges of the different sexes of the same subspecies do not wholly coincide (Betram & Bradley, 1972) though this biological anomaly does not prevent the authors using the category.
