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

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)

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 ...

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.

Surveying native egg parasitoids and predators of the invasive Halyomorpha halys in Northern Italy

Journal of applied entomology, 2018
The invasive Halyomorpha halys (Heteroptera: Pentatomidae) is a key pest of fruits in the Emilia‐Romagna region of Italy. For the development of a sustainable management programme, knowledge of its native natural enemy community and its efficacy is ...

Status of Stink Bug (Hemiptera: Pentatomidae) Egg Parasitoids in Soybeans in Louisiana

Environmental Entomology, 2018
Stink 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.
