Egg Parasitoids in Cereal Crops Ecosystem

2013
The 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.

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.

EVOLUTION AND MANIPULATION OF PARASITOID EGG LOAD

Evolution, 2009
In 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.

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 Tobacco Ecosystem

2013
In 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
