Insect Management in Blackberries¹

Several kinds of insects have been found on blackberries. If production expands, insect problems are likely to become more numerous and extensive.

Thrips are tiny insects that infest blooms and berries. Injury to fruit has been attributed to their feeding and their presence is objectionable on harvested berries. Spider mites sometimes become numerous on leaves, especially during dry weather. Caterpillars and beetles that feed on foliage have been occasional problems. Stinkbugs, plant bugs, and sap beetles may become a problem on berries.

It appears that a regular spray program may be desirable in some areas. The application of malathion at weekly intervals beginning just as the plants flush out in the spring and continued through harvest is a possibility. Apply malathion at the rate recommended for thrips. Use only the emulsifiable concentrate near harvest to avoid visible residues on harvested berries by wettable powder. See Table 1.
