Name a common biocontrol agent used to parasitize pest eggs.

Egg parasitoids are a powerful tool in biological control because they target pests right at the start of their life cycle, stopping them before they can damage crops. Trichogramma wasps are classic examples: a female wasp oviposits inside the eggs of pest insects, and the developing larva consumes the host egg from within, preventing emergence of the pest. This inside-the-egg parasitism makes them extremely effective for reducing populations of moths and other pests whose eggs are easy targets, and they’re widely used in integrated pest management programs. By contrast, the other options mainly involve predators that eat pest organisms or strategies that disrupt reproduction rather than parasitize eggs, so they don’t fit the specific egg-parasitism role described here.
