What term is used to describe an agent that is destructive to eggs?

The term that specifically describes an agent that is destructive to eggs is "ovicide." Ovicides target the eggs of insects and other arthropods, inhibiting their development or leading to their destruction. This is particularly important in pest management strategies, where controlling the reproductive phase of pests can significantly reduce their populations.

Insecticides are broader in scope, as they are designed to kill insects at various life stages, but do not exclusively target eggs. Herbicides are chemicals that control or kill unwanted vegetation, while fungicides are used to manage fungal infections in plants. Each of these terms relates to different types of organisms or lifecycle stages, making ovicide the most accurate term for agents that specifically harm eggs.
