Wasp parasite of woolly apple aphid

Wasp parasite of woolly apple aphid

A tiny North American wasp – Aphelinus mali – is a natural enemy of woolly apple aphids, and was introduced to New Zealand in 1921 to help control the pest. Female wasps lay a single egg into aphid nymphs. The nymph dies and the wasp develops into an adult inside the dead body over 20–50 days.
