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.

In Vitro Rearing of Egg Parasitoids
, 2009 Regardless the success achieved in the rearing of natural or factitious hosts for the mass production of natural enemies, the usual need to rear two different species when producing natural enemies based on in vivo rearing systems stimulated the investigation on their artificial rearing.

Egg Parasitoids in Cereal Crops Ecosystem
2013The major targets of egg parasitoids occurring in cereal crops include mainly stem borers (Scirpophaga, Chilo), leaf folders (Cnaphalocrocis), the gall midge and leaf/plant hopper. Among trichogrammatids commonly occurring in cereal ecosystem are the ‘minutum’ group (T. chilotraeae, T. pretiosum, T. chilonis) and the ‘japonicum’ group (T. japonicum, T.

, 2013 In Sicily, field collections of egg masses of the southern green stink bug, Nezara viridula (L.) (Heteroptera:Pentatomidae), revealed that two solitary parasitoids, Trissolcus basalis (Wollaston) (Hymenoptera: Platygastridae) and Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae), can exploit the same egg mass.

EVOLUTION AND MANIPULATION OF PARASITOID EGG LOAD
Evolution, 2009In proovigenic parasitoids such as Leptopilina boulardi, the female emerges with a limited egg load and no further eggs are produced during its adult life. A female thus runs the risk of exhausting this limited supply of eggs before the end of her life.

Egg Parasitoids in Tobacco Ecosystem
2013In tobacco ecosystem, the common lepidopteran targets for egg parasitoids include Spodoptera litura, Helicoverpa armigera and Scrobipalpa heliopa. For bio-suppression of S. litura, Trichogramma chilonis was found to be less effective than Telenomus remus. Among the different tobacco types (cultivars), those with higher number of glandular trichomes and

Biological Control, 2016
Accurate evaluation of the biological control services provided by insect natural enemies requires a consideration of the full diversity of means by which they can cause reductions in host or prey populations. Here, we discuss the fact that host attacks by egg parasitoids often result in failed parasitoid offspring development, while causing the host ...

Genetics of the Behavioral Ecology of Egg Parasitoids
2009Biological 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 ...
