Sex Ratio Modulators of Egg Parasitoids

2009
The importance of sex ratio s in the biology and biocontrol application of egg parasitoids can be summarized as the cost of producing males. For both the biocontrol practitioner and the biocontrol agent a surplus of healthy fecund females is highly desirable.

Egg Parasitoids of Fruit Crop Pests

2013
Among the temperate fruit crops, there is a good scope for biocontrol of the codling moth with repeated release of Trichogramma embryophagum Htg., while the Indian gypsy moth is subjected to varying levels of natural parasitisation by Anastatus kashmirensis Mathur.

Egg Parasitoids in Legume Crops Ecosystem

2013
In India, legume crops as targets for biocontrol include pigeon pea, chickpea, pea, black gram, groundnut, soybean and lucerne. The egg parasitoids occurring in or used for biocontrol in legume crop ecosystem in India are mainly Scelionids (Telenomus sp.) and Trichogrammatids (Trichogramma, 14 species; Trichogrammatoidea, 7 species), besides the ...

Insect egg deposition induces Pinus sylvestris to attract egg parasitoids

Journal of Experimental Biology, 2002
SUMMARY Plant volatiles released in response to feeding insects are known to attract enemies of the feeding herbivores. In this study, egg deposition by a herbivorous insect was shown to induce a gymnosperm plant to emit volatiles that attract egg parasitoids.

Parasitoid egg shell changes in a suitable and unsuitable host

Journal of Ultrastructure Research, 1974
The egg shell of the braconid, Cardiochiles nigriceps , Viereck consists of two distinct layers: an inner, crystalline, proteinaceous chorion, and microvilluslike projections embedded in an outer fibrous chorion. In a suitable host the fibrous layer and projections are slowly lost during the first 12 hours.

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

Intraguild interaction between egg parasitoids: the role of the host egg mass size and parasitoids’ reproductive capacities

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.
