Gypsy Moth Responses to Pheromone Enantiomers as Evaluated in a Sustained-Flight Tunnel

(−)-Disparlure reduced: (1) the durations of anemotactic flights of male gypsy moths, Lymantria dispar (L.), in plumes of (+)-disparlure; (2) the rate of moth flight with respect to a moving floor pattern; and (3) the percentage of moths initiating anemotactic flights. The effects of (−)-disparlure were much more apparent on in-flight than pre-flight behavio
