Host egg chorion structure influencing host suitability for the egg parasitoid Trichogramma Westwood

Journal of Insect Physiology, 1990
Abstract Success of development of the egg parasitoid Trichogramma Westwood (Hymenoptera, Trichogrammatidae) is higher in Mamestra brassicae (L.) (Noctuidae) than in Pieris brassicae (L.) (Pieridae), two lepidopterous host species that are common on cruciferous plants in Europe.

Floral resources enhance fitness of the parasitoid Hadronotus pennsylvanicus (Hymenoptera: Scelionidae) but not biological control of its host Leptoglossus zonatus (Heteroptera: Coreidae)

Environmental Entomology
The diet of adult parasitoid wasps is vital for their survival and reproduction. However, the availability of food resources, such as plant nectar, can vary widely in cropping systems, potentially affecting parasitoid fitness and thereby biological ...

Nutritional Ecology of Insect Egg Parasitoids

2009
All animals require food and the food is the major issue that determines the biology of an organism. But there are a number of issues associated with the food that are involved. These include the location, confirmation, consumption, utilization and allocation of the resource (food) to the various aspects of the organism’s life style that determines the

Genetics of the Behavioral Ecology of Egg Parasitoids

2009
Biological control with egg parasitoids has been mainly based on a trial-and-error approach and, as a result, its success rate has remained low. Several authors recently proposed that, on the other hand, a behavioral ecology approach of biological control, based on optimization theoretical models, can provide important means for improving the success ...

Other Egg Parasitoids: Research for Utilisation

2013
Among the seven hymenopteran families (other than Trichogrammatidae), which are known to exploit the eggs of pest insects, Scelionidae and Mymaridae are entirely egg parasitoids, while Encyrtidae, Eulophidae, Eupelmidae, Platygasteridae and Tetracampidae include scattered genera and species, a few of which as immatures or adults act as egg predators ...

Egg Parasitoids Commercialization in the New World

2009
This chapter deals with the commercialization of egg parasitoid species that attack crop pests in the New World. It is discussed the current status of the worldwide commercialization of natural enemies in the U.S.A. and Europe, and with more details in the New World, including Brazil, Colombia, Mexico, Cuba, Ecuador, Venezuela and Peru. The reasons for

Reproduction and Immature Development of Egg Parasitoids

2009
In this chapter I review the recent advances on egg parasitoids reproduction and immature development. Sperm production in adult male parasitoids varies depending on the status of their testes at emergence and these differences in sperm production are described by the spermatogeny index. Polygyny is common in Hymenoptera parasitoids and males that mate
