ALFALFA WEEVIL - Adults remain scarce in alfalfa fields. Only three weevils were swept from the 42 fields sampled from April 30-May 7. Weevil counts, and egg deposition in alfalfa stems, are expected to increase noticeably with warmer temperatures in the week ahead.

PEA APHID - Egg hatch was observed in Dane, Green, Juneau, Rock and Sauk counties, where nymphs were collected at the very low rate of 1-4 per 100 sweeps. Alfalfa sampled in La Crosse and Monroe counties this week contained no aphids.
