Common names:  Currant Fruit Fly, Gooseberry Maggot

Scientific name:  Epochra canadensis

Region:  This fly is found in the United States and southern Canada.

Life cycle:  This insect produces one generation each year and overwinters in the soil as a pupa.

It merges from the soil in April or May and lays its eggs in the fruit.  When the fruit drops, the maggots enter the soil.

Physical Description:  This fly is about the size of a housefly, 1/5 to 1/3 inch long.  It is yellow to dark brown with dark bands on the wings.  Its eggs are laid singly inside the fruit, and the larva is yellowish and ranges from 1/3 to 1/2 inch long.

Feeding characteristics:  This pest attacks the currant and gooseberry plants.  The maggots eat inside the developing fruits, causing them to turn red and prematurely fall from the tree.

Controls:  As soon as blossoms begin to wilt, dust with rotenone in two to three applications at weekly intervals.
