Pests in Gardens and Landscapes

Seasonal development and life cycle—Raspberry cane maggot

Adult flies emerge from the soil in late April and lay eggs on the tips of new canes or shoots. Larvae hatch and tunnel into young shoots and then move down the cane, where they cause girdling to the shoot tip. They make their way into the soil, where they overwinter as pupae.
