Volume 58 Number 1 Date 05/02/2013 ALFALFA PESTS - Surveys in alfalfa have not yet started. Most of the state's alfalfa acreage remains dormant or too short to sweep. Sampling for alfalfa weevil adults and other early-season alfalfa pests is planned for next week if the weather improves. PEA APHID - The degree day accumulation above base 40°F is appropriate for hatching of overwintered eggs. Pea aphids were first observed last season on March 19 and are usually active by mid- to late April. This insect is of primary concern in early spring as alfalfa stands are becoming established and about the time first crop hay is harvested. -- Krista Hamilton, DATCP Entomologist
