MN Fruit & Vegetable IPM News - Vol. 1, No. 1

Thrips infested fruit are very small and hard (seedy). Seedy berry symptoms include reduced fruit size, dull color, leatheriness, and seediness all over. It is believed that thrips do not overwinter in the Midwest, and that they are likely carried by air currents from southern areas, arriving here suddenly in high populations.

Strawberry bud weevil (SBW) (clipper)

SBW adults puncture blossom buds, deposit eggs in the nearly mature buds, and then girdle the bud so that it is hanging or falls to the ground. Injury is most common along edges of fields near woodlots.
