The Egg Parasitoids Trichogramma: From Laboratory Mass Rearing to Biological Control of Lepidopteran Pests

Biocontrol Science and Technology, 2021
Trichogramma egg parasitoids are successfully used for biological control of a wide range of lepidopteran pests worldwide. However, the field success depends upon their performance that could be influenced by the conditions of laboratory mass rearing ...

Parasitoid-Induced Host Egg Abortion: An Underappreciated Component of Biological Control Services Provided by Egg Parasitoids

Biological Control, 2016
Accurate evaluation of the biological control services provided by insect natural enemies requires a consideration of the full diversity of means by which they can cause reductions in host or prey populations. Here, we discuss the fact that host attacks by egg parasitoids often result in failed parasitoid offspring development, while causing the host ...

Evolution and Manipulation of Parasitoid Egg Load.

Evolution; International Journal of Organic 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.

Insights from the biogeographic approach for biocontrol of invasive alien pests: Estimating the ecological niche overlap of three egg parasitoids against Spodoptera frugiperda in China.

Science of the Total Environment, 2022
Spodoptera frugiperda, the fall armyworm, causes major damage to maize and >80 other crops worldwide. Since S. frugiperda successfully invaded China in 2018 via long-distance migration from Myanmar, it has caused major maize yield losses and posed a ...

Chinese oak silkworm Antherae pernyi egg, a suitable factitious host for rearing eupelmid egg parasitoids.

Pest Management Science, 2022
BACKGROUND Eupelmid egg parasitoids in the genera Anastatus and Mesocomys are important biological control agents for lepidopterous and hemipterous pests worldwide. The egg of Chinese oak silkworm Antheraea pernyi has been widely used for mass rearing of

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.

Responses of native egg parasitoids to the invasive seed bug Leptoglossus occidentalis

Agricultural and Forest Entomology, 2021
The Western conifer seed bug Leptoglossus occidentalis, a native insect of North America, was accidentally introduced in Europe in the late 1990s. Since then, it has spread rapidly.

Classical biological control of invasive stink bugs with egg parasitoids - what does success look like?

Pest Management Science, 2020
Although the enemy release hypothesis forms the theoretical basis for classical (=importation) biological control of invasive pests, its core assumptions are not always examined.

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.
