How to Manage Pests

Pests in Gardens and Landscapes

Dryberry mite—Phyllocoptes gracilis

Adult mites have an oval body. They lack antennae and body segmentation. They are found on ripe fruit, in cracks, and in crevices.

Damage

Dryberry mites may damage both raspberries and blackberries. Ripening berries with dryberry mite infestations become dry.

Solutions

Tolerate damage or prune out and destroy damaged fruit. Pesticides should be avoided in home gardens. If sprays are needed, apply sulfur at the delayed-dormant stage, just before buds break. Several applications of horticultural oil spaced two to three weeks apart after green fruit stage may also provide control. Don't apply oil within one month of a sulfur treatment.
