Biochemical composition of Eurygaster integriceps eggs

One of the major problems concerning in vitro rearing of insect parasitoids, used as biological control agents, is diet composition, which must be nutritionally adequate to that of the milieu, offered by the relevant natural host (House, 1977). A good approach to resolving this problem for egg parasitoids is investigation of host eggs' chemical composition. In the present paper we applied it to the eggs of the wheat bug Eurygaster integriceps (Putton). The wheat bug is a serious pest in the fields of Eastern Europe, and the reported data would be helpful toward preparation of a chemically defined medium for in vitro rearing of its egg parasitoids.
