African fig wasp parasitoid communities
1994Abstract What are fig trees and fig wasps? Fig trees are a group of approximately 850 species placed in the genus Ficus (Moraceae), and are characterized by their unique inflorescence-the fig. Around 105 Ficus species are found in Africa, where they range in size from small shrubs to huge rain forest emergents (Berg 1990; Berg and Wiebes

Mating systems of parasitoid wasps
1997ABSTRACT Parasitoid wasps are a large group of hymenopteran insects whose larvae develop by feeding on the bodies of other insects. The spatial distributions of both the hosts and the parasitoid larvae influence the mating systems found in these wasps.

Selective information use in parasitoid wasps
Animal Biology, 2006Abstract Foraging animals frequently have to decide where to search, what host or prey to accept, and when to leave a patch. To achieve optimal patch exploitation rates, foragers can base their decisions on information about the quality of the current patch and on an estimate of the quality of the entire habitat.

Reproductive Strategies in Parasitoid Wasps
The American Naturalist, 1973In an effort to explain different reproductive strategies among parasitoid wasps, differences in potential fecundity of members of the family Ichneumonidae were compared in relation to the availability of the host and the probability of survival of the parasitoid once it was associated with the host.

Host-feeding strategies of parasitoid wasps
Evolutionary Ecology, 1993Three models of the evolution of host-feeding behaviour in parasitoid wasps are developed. The first assumes that the wasp host feeds purely to obtain resources to mature eggs (limited resource model) while the second assumes that host feeding provides energy for maintenance (pro-ovigenic model).

Mixed sex allocation strategies in a parasitoid wasp
Oecologia, 1997The sex allocation strategy of the parasitoid Laelius pedatus (Hymenoptera: Bethylidae) on different-sized hosts was investigated. The wasp lays from one to five eggs, and clutch size increases with host size. On the smallest hosts, single male eggs are laid, while on slightly larger hosts single female eggs are laid.

Sexual size dimorphism in parasitoid wasps
Biological Journal of the Linnean Society, 1987Sexual 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 families. In most species, females are generally larger than males, though the range of male and female sizes overlap. Species in the family Ichneumonidae differ significantly from

Systematics, Biology, and Evolution of Microgastrine Parasitoid Wasps
Annual Review of Entomology, 2018The braconid parasitoid wasp subfamily Microgastrinae is perhaps the most species-rich subfamily of animals on Earth. Despite their small size, they are familiar to agriculturalists and field ecologists alike as one of the principal groups of natural enemies of caterpillars feeding on plants.

Offspring Sex Ratios in Parasitoid Wasps
The Quarterly Review of Biology, 1987Laboratory and field studies on about 100 species in sixteen families indicate that several factors can influence offspring sex ratios (males: females) in parasitoid wasps. For many species, the offspring sex ratio increases with one or more of the following: (1) maternal age at ovipositing or number of days since insemination; (2) the age of the male ...
