Notes on Saskatoon Berry Insects
Saskatoon bud moth
Identification
Bud moth larvae are yellow to light green and feed on developing buds
as buds break open and expand. They cause tiny holes in the flower buds,
which may ooze at the point of injury. Leaves are tied together with webs,
and larvae can be found inside.
Period of activity
Saskatoon bud moths overwinter as pupae. Bud moth adults are active in
early spring and lay eggs on the base of buds and the bark of twigs. Eggs
hatch in April and the larvae bore into the base of the bud. The larvae
are full grown by petal fall.
Management Notes
Apply superior oil at bud break to affect egg-lay and hatch. Use a high
volume of water to ensure thorough coverage of twigs and buds.
