Parasitoid—Host Relationship
摘要：
The chemical ecology of interspecific interactions is extremely diverse and complex and is exemplified by the insect parasitoid—host relationship. Because insect parasitoids represent a third trophic level (Price et al ., 1980), they are influenced not only by the chemicals emanating from hosts, but by chemicals emanating from the host's food or other associated organisms. The complexity becomes apparent when we consider that a host insect may support several different parasitoid species, each of which is unique in its response to the host, and these may also interact with each other. Askew (1971) estimates that there are over 100 000 species of parasitic Hymenoptera worldwide, of which over 16 000 occur in North America (Krombein et al ., 1979). It is estimated that only 10–35% of the Ichneumonidae, one of the better known groups of Hymenoptera, have been described (Townes, 1969). Add to this the parasitic Diptera and other parasitic groups and one can readily see the difficulties in developing overall concepts on the chemical ecology of the parasitoid—host relationship.
