Volume 57 Number 5 Date 05/10/2012 SOYBEAN APHID - The DATCP Pest Survey Program, in partnership with the UW-Madison, is seeking volunteers for its 2012 Soybean Aphid Survey. Participants will be asked to provide exact field locations and basic production information, including: 1) Soybean variety and number, 2) Seed treatment chemicals, 3) Planting date, 4) Seeds planted per acre, 5) Row spacing, 6) Fertilizer and herbicide use, 7) Foliar pesticide applications, and 8) Average yield (bu/acre). In exchange, volunteers will receive current aphid counts as fields are sampled. The program expects to check each soybean field 2-3 times from June through August. Consultants, agronomists, county agents and growers interested in taking part in the annual survey should email or call Krista Hamilton by June 1 at krista.hamilton@wi.gov or 1-866-440-7523. Specific counties in which fields are needed are Columbia, Dane, Dodge, Green, Iowa, Jackson, Jefferson, Lafayette, Manitowoc, Richland, Rock, Sauk and Walworth, although all sites will be considered for the survey. BEAN LEAF BEETLE - Surveys of alfalfa found overwintered beetles in Dane, Lafayette and Rock counties since the last report. This insect is economically unimportant to forage crops, but its abundance can be an indicator of soybean defoliation potential. The earliest-planted soybean fields are highly attractive to overwintered beetles and should be checked for feeding injury beginning at emergence. --Krista Hamilton, DATCP Entomologist
