Quality Control of Mass Reared Egg Parasitoids

2009
In this chapter we will present methods for determination of the quality of mass reared egg parasitoids. Before we describe quality control guidelines, we will first outline the development of quality control of natural enemies, summarize the basic considerations concerning management of laboratory populations, and discuss obstacles in mass rearing ...

Selectivity of Pesticides to Egg Parasitoid in Sugarcane

Sugar Tech, 2018
The aim of this study was to evaluate the selectivity of herbicides, insecticides, and fungus Metarhizium anisopliae (Metsch.) on the immature stages of Trichogramma galloi Zucchi. Egg masses of Diatraea flavipennella Box, 1931, containing 30 eggs each, were immersed in test solutions for 5 s, before and after parasitism.

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

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 of Australian Coreidae (Hemiptera)

Australian Journal of Entomology, 2001
AbstractTen microhymenopteran species are recorded as parasitoids of the eggs of coreid bugs in Australia: Chrysochalcissa olivacea Girault (Torymidae) from Amorbus biguttatus Stål and Pternistria bispina Stål; two species of Anastatus Motschulsky (Eupelmidae) from Mictis profana (F.), Amorbus alternatus Dallas, Amblypelta lutescens lutescens (Distant)

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.

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.

Diapause in the egg parasitoid Trichogramma cordubensis: role of temperature

Journal of Insect Physiology, 2002
The role of temperature in the induction of diapause in Trichogramma cordubensis (Hymenoptera: Trichogrammatidae), under controlled laboratory conditions, was investigated using Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) eggs as hosts. Results indicate that prestorage temperatures and the duration of exposure of the parasitoids to these ...
