Aphidius ervi female wasps have an excellent searching ability for nymph or adult aphids, by sensing the odor of infested plants and the aphid honeydew secretion. Using her ovipositor, the female will insert an egg inside the aphid host then when the egg hatches, the larva begins to eat the aphid from the inside out causing its death. The dead aphid will be mummified and remain attached to the leaf. Each female wasp can lay up to 350 eggs, most of them during the first 4-5 days of adulthood. The presence of a parasitic wasp can cause aphids to drop from the plant in a panic reaction.
