Controlling Pests by Egg Parasitoid Insects and Their Production

More about the book

Egg parasitoids, particularly Trichogramma species, are effective biological control agents against various agricultural pests, thriving in diverse crops such as maize, cotton, and fruit orchards. Their rapid generation time facilitates mass production, enabling them to target Lepidopteran pests at the egg stage. The selection of indigenous species for release is based on their adaptation to local climates and habitats, enhancing their effectiveness. The efficiency of these parasitoids is influenced by the factitious hosts used for rearing, including species like Sitotroga cerealella and Ephestia kuehniella.
