title: Field responses of redheaded pine sawfly males to a synthetic pheromone and virgin females in Florida.
abstract: Field tests using the sawfly pheromone [3,7-dimethylpentadecan-2-ol acetate with (-)-erythro configuration (2S,3S)] were conducted near Gainesville, Florida, during 1978-1981 to determine the attraction ofNeodiprion lecontei males to baited traps with respect to time of year and time of day. Greatest numbers of males were caught during May, July, and September in traps placed within a pine stand from July 1978 to July 1979. Males were only caught between 1400 and 2000 hr on 10 dates in June and 10 dates in September-October 1980, and 10 dates in June 1981, with greatest catches from 1600-1800 hr. Catches in a synthetic-baited trap and in virgin female-baited traps were similar with respect to time of day.
