How to Manage Pests

Pests in Gardens and Landscapes

Natural enemies of adelgids

Many predators feed on adelgids, including several species of small dark lady beetles, lacewings, and the maggotlike larvae of some small flies in the Cecidomyiidae and Chamaemyiidae families. Predators are especially important in natural forests, where most adelgids are uncommon. Except for the balsam woolly adelgid, Adelges piceae, a serious pest of fir in the Northwest and Northeast, there has been little research on the adelgid's natural enemies, especially in landscapes.
