Abstract
The pheromone releasing behavior of Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae) females was greatly influenced by prevailing air velocities. The length of time per night that females spent releasing pheromone when exposed to air velocities ranging from 0.3 to 1.0 meter per second was about 2 times that of females held in calm air. Release time per night gradually approached zero as the wind velocity was increased to 4.0 meters per second. Each female that released pheromone typically did so on several separate occasions per night. The length of individual pheromone release periods increased with decreasing wind velocity. The precopulatory behavior of T. ni females is described in detail and adaptive features of this behavior as related to wind velocity are discussed.Keywords
