Pear Slug/Pear Sawfly

Pear Slug/Pear Sawfly (Caliroa cerasi)

The larvae of pear sawfly resemble small, black, elongate slugs, hence the common name pear slug. There are two generations a year. Larvae feed on the upper surface of pear and cherry leaves removing the green epidermis. High populations can defoliate trees. Conventional insecticides applied against other insect pests generally control pear sawfly. Malathion and Sevin sprays will also control the larvae.
