Aphelinus mali (parasitic wasp)

Aphelinus mali is a small parasitic wasp that helps control populations of woolly apple aphids, common pests on apple trees. The wasp lays its eggs inside the aphids, and eventually, the developing wasp larvae consume and kill the aphids from within. This natural pest control reduces the need for chemical pesticides, promoting healthier apple orchards. Aphelinus mali is considered a beneficial insect in integrated pest management programs due to its specificity and effectiveness in managing aphid infestations, contributing to sustainable orchard practices.
