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

Understanding the response of egg parasitoids to host density is essential for efficient biological control. However, this response has been little investigated in parasitoids that attack eggs of insect pests that transmit plant pathogens in a persistent-

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 ...

Quality Control of Mass Reared Egg Parasitoids
2009In 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, 2018The 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 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.

Egg parasitoids of Australian Coreidae (Hemiptera)
Australian Journal of Entomology, 2001AbstractTen 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)

Egg Parasitoids in Cotton Ecosystem
2013The 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

Status of Stink Bug (Hemiptera: Pentatomidae) Egg Parasitoids in Soybeans in Louisiana
Environmental Entomology, 2018Stink bugs are important insect pests of soybean, Glycine max (L.), in Louisiana. Scouting, economic thresholds, and insecticide applications are the main strategies used in the integrated pest management of soybean insect pests.
