How to Manage Pests

Pests in Gardens and Landscapes

Identification and confirmation: Low temperatures

Temperatures below about 60 F during flowering may prevent pollination of some simple, one-seeded fruits, resulting in distorted, "catfaced" berries. The damage appears identical to the catfacing caused by lygus bugs, but lygus bug damage occurs in late spring and early summer and low-temperature injury symptoms develop in early to mid-spring.
