Abstract
Adult bean leaf beetles, Cerotoma trifurcata (Forster), were trapped as they entered Illinois woodlots during October 1979 and 1980. Soil litter samples and emergence traps detected the presence and distribution of overwintering beetles within woodlands. Spring beetle emergence from overwintering sites began in April and extended through May. In 1980 the majority of beetles emerged in May, but in 1981 the majority emerged during April. Beetle emergence and soybean planting dates were well synchronized in 1980, and poorly synchronized in 1981, resulting in a population crash. A simple predictive model for beetle emergence based on degree-day accumulation was developed. This proved superior to simple calendar date predictions of peak colonization flights.This publication has 4 references indexed in Scilit:
