Oviposition behavior in phytophagous insects and entomophagous parasitoids is often
modified by the presence of conspecific brood (eggs and larvae). Often, females avoid …

A mathematical model is constructed to explain a density‐dependent increase in the
progeny sex ratios of gregarious parasitoids. In the model we considered non‐cooperative …

The pay-off from the 2nd egg laid in a host (Drosophila subobscura) by a female of
Leptopilina heterotoma was determined for 5 intervals between the first and 2nd oviposition …

Oviposition behavior, intra-and interspecific host discrimination, and super-and
multiparasitism by the scelionids Telenomus busseolae and T. isis were studied using …

Sexual dimorphism in body length and proportion of overlap between the ranges of body
length for males and females were estimated for 361 species of parasitoid wasps from 21 …

Studies of host discrimination by hymenopterous parasitoids of insects, published during
1980-88, are reviewed. The parasitoids discriminate by detection of either external or …

1. Ceratobaeus spp. enter the nest of their host spider and oviposit into eggs through the thin
silk eggsac. 2. Temperatures below 15 C limit oviposition by slowing parasites down. 3 …

The gregarious idiobiont ectoparasitoid, Sclerodermus pupariae Yang et Yao, is a natural
enemy that parasitizes buprestid and cerambycid beetle larvae in China. In a recent …

The host acceptance behavior of Telenomus heliothidis Ashmead in the laboratory was
investigated. Host acceptance was broken into seven discreet steps: host encounter …

Behavioural events underlying observations of uniform egg dispersion in field populations of
the cabbage seed weevil, Ceutorhynchus assimilis, among winter rape, Brassica napus …
