Pegomya rubivora Coquillett Loganberry cane fly

Infestations of this locally distributed pest occur on blackberry, loganberry, raspberry and Tayberry. Adult flies are active in the spring, eggs then being deposited on newly emerging canes. The larvae feed gregariously. They burrow downwards to the base of the new canes, which are often girdled; this causes the canes to wilt and die. Pupation occurs in the soil, and there is just one generation annually.
