Regulation of Ovulation and Egg Disposal in the Parasitic Hymenoptera1

Among the attributes of the parasitic Hymenoptera that contribute to the ability of certain species to maintain host populations at low densities is the power to restrict egg deposition to sites suitable for the continued development of the offspring, and to regulate, regardless of host density, the number of eggs deposited per host (Flanders 1947). High searching capacity is, in part, a function of female longevity correlated with the conservation of reproductive material. It is self evident that time used in wasteful oviposition means less time for searching and consequently less effective control of the host.
