Title: Sex Pheromones of Noctuid Moths. XXVI. Female Release Rate, Male Response Threshold, and Communication Distance for Trichoplusia ni1,2

Those releasing pheromone typically did so for about 40 minutes per night in 2 or more separate periods. A gas-liquid chromatographic and a bioassay method were developed, allowing measurement of pheromone emanating from single females. The mean pheromone release rate for females was about 7×l0−3 µg/minute. The minimum male threshold of response to pheromone, determined by laboratory bioassay, was found to be at about 8 molecules/mm3 of air. These data are used to estimate potential female to male communication distances in the field.Read More
