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 ...

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.

Size-induced reproductive constraints in an egg parasitoid

Journal of Insect Physiology, 2012
The size of adult parasitoids is influenced by the quantity and quality of resources available during immature development. Gregarious development of endoparasitoids results in scramble competition where the resources are shared among individuals developing into the same host.

Egg Parasitoids in Cotton Ecosystem

2013
The egg parasitoid fauna, especially trichogrammatid species, associated with the spotted bollworms (Earias vittella, E. insulana), pink bollworm (Pectinophora gossypiella) and American bollworm (Helicoverpa armigera), which are the key target pests in cotton ecosystem, are discussed. Inundative releases of two native species (Trichogramma chilonis and

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.

Antennal Structures Used in Communication by Egg Parasitoids

2009
Egg parasitoids are considered the most effective biocontrol agents of crop pests among parasitic wasps, since they are able to remove the herbivore from the agroecosystem before larval eclosion. The use of arthropod eggs as hosts by parasitoids has evolved in the Hymenoptera at least in 14 families.
