Parasitoid Foraging and Learning
1995The diminutive size of most parasitoids undoubtedly has limited their choice as subjects for behavioral study, despite their great diversity in lifestyles and reproductive strategies. The present chapter addresses their foraging behavior as influenced by learning.

Egg Load Evolution in Parasitoids
The American Naturalist, 2000Parasitic wasps lay their eggs in or on other insects. Allocation of resources to reproduction (eggs) and survival (life span) should maximize reproductive success, but stochasticity in the number of hosts encountered precludes an exact match of allocation with reproductive opportunity.

Parasitoid Competition and the Dynamics of Host-Parasitoid Models
The American Naturalist, 1988The standard host-parasitoid models assume that each parasitized host yields the same number of parasitoid progeny; but in many parasitoid species, the number of progeny per host depends on the number of times that host was encountered. I present a family of new host-parasitoid models incorporating this encounter-density-dependent variability in ...

What determines host range in parasitoids? An analysis of a tachinid parasitoid community
Oecologia, 2003Despite the vast diversity of parasitic insects and their importance in natural and agricultural communities, our knowledge of what determines their patterns of association with hosts remains sparse. Unlike most parasites that tend to be specialized, parasitoid flies in the family Tachinidae exhibit a broad spectrum of host-specificity, with many ...

Parasitoids, polydnaviruses and endosymbiosis
Parasitology Today, 1990Symbiotic associations traditionally have been treated as evolutionary curios rather than as a major source of evolutionary innovation. Recent research on a wide variety of organisms is changing this view and is breaking down the barriers between the traditional categories of parasitism, commensalism and mutualism, to produce a more flexible view of ...

Parasitoid aggregation and interference in host–parasitoid dynamics
Ecological Entomology, 20161. Parasitoids do not distribute themselves evenly among available patches, which has an important bearing on the dynamics of host–parasitoid interactions. This study examined the density‐dependent nature of aggregation of the parasitoid D irhinus giffardii

Parasitoid communities, parasitoid guilds, and biological control
1994Abstract In the native home of a given phytophagous insect species, we can expect to find several species of parasitoids characteristically associated with the particular insect at a given location. Such a cluster of species constitutes a ‘parasitoid community’, the members of which may either remain relatively constant or vary ...
