Egg Load Evolution in Parasitoids

The American Naturalist, 2000
Parasitic wasps lay their eggs in or on other insects. Allocation of resources to reproduction (eggs) and survival (life span) should maximize reproductive success, but stochasticity in the number of hosts encountered precludes an exact match of allocation with reproductive opportunity.

Long-Term Mass Rearing Impacts Performance of the Egg Parasitoid Telenomus remus (Hymenoptera: Platygastridae)

Journal of entomological science, 2020
The effects of long-term laboratory rearing on the performance of Telenomus remus Nixon (Hymenoptera: Platygastridae), an egg parasitoid of Spodoptera frugiperda (J.E.

Effect of temperature on the walking behaviour of an egg parasitoid: disentangling kinetic response from integrated response

, 2020
1. This study investigated the effect of temperatures ranging from 10.8 to 34.2 °C on seven walking parameters of an egg parasitoid, Anaphes listronoti.

Release density, dispersal capacity, and optimal rearing conditions for Telenomus remus, an egg parasitoid of Spodoptera frugiperda, in maize

, 2020
We determined the release density, dispersal capacity, and optimal storage conditions for the parasitoid Telenomus remus Nixon to control Spodoptera frugiperda (J.E. Smith).

In Vitro Rearing of Egg Parasitoids

2009
Regardless the success achieved in the rearing of natural or factitious hosts for the mass production of natural enemies, the usual need to rear two different species when producing natural enemies based on in vivo rearing systems stimulated the investigation on their artificial rearing.

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.

EVOLUTION AND MANIPULATION OF PARASITOID EGG LOAD

Evolution, 2009
In proovigenic parasitoids such as Leptopilina boulardi, the female emerges with a limited egg load and no further eggs are produced during its adult life. A female thus runs the risk of exhausting this limited supply of eggs before the end of her life.

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 ...
