Parasitoid Foraging and Learning

1995
The 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.

Parasitoids, polydnaviruses and endosymbiosis

Parasitology Today, 1990
Symbiotic 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 ...

Parasitoids

2009
Publisher Summary This chapter focuses on the parasitoids, insects with a parasitic larval stage that develops by feeding on the body of a single host insect or other arthropod. Feeding by the larval parasitoid invariably results in the death of its host, and the resulting adult parasitoid is a free living insect.

Egg Load Evolution in Parasitoids

The American Naturalist, 2000
Parasitic 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.

Insect immune resistance to parasitoids

Insect Science, 2008
AbstractInsect host—parasitoid interactions involve complex physiological, biochemical and genetic interactions. Against endoparasitoids, immune‐competent hosts initiate a blood cell‐mediated response that quickly destroys the intruders and envelops them in a multilayered melanotic capsule. During the past decade, considerable progress has been made in

What determines host range in parasitoids? An analysis of a tachinid parasitoid community

Oecologia, 2003
Despite 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 ...

Immunological basis for compatibility in parasitoid-host relationships.

Annual Review of Entomology, 1995
The insect immune system serves as a key defense against attack by parasitoids. Incompatible hosts often eliminate parasitoids by encapsulation, a process in which hemocytes form a multilayered envelope around the invading organism.

Resource acquisition, allocation, and utilization in parasitoid reproductive strategies.

Annual Review of Entomology, 2008
Parasitoids display remarkable inter- and intraspecific variation in their reproductive and associated traits. Adaptive explanations have been proposed for many of the between-trait relationships.

Host phylogeny and specialisation in parasitoids

Ecology Letters, 2012
Ecology Letters(2012)15: 453–460AbstractThe host range of insect parasitoids and herbivores is influenced by both preference‐related traits which mediate host choice behaviour, and performance‐related traits which mediate the physiological suitability of the consumer‐resource interaction.
