Abstract:Synthetic sex pheromone of the cabbage looper, Trichoplusia ni(Hübner), was released at various constant rates from several trap designs. An open, horizontal, cylindrical trap (A), 11 em 10, was used as the standard for comparison. A circular trap (B) consisted of a 60- em-radius circular roof supported 4 em above a circular base. A double cone trap (C) consisted of an upright cylinder having a metal base and wire screen lid plus 2 screen cones through which attracted male moths flew. Males were ensnared in Stickem® in traps A and B and were captured alive in trap C. Optimal pheromone release rates varied among the traps, being about 0.3 kg per minute from trap A and about 1kg per minute from traps Band C. Rates about 3 times higher or lower than the optimum for each trap generally resulted in reduced captures. When evaluated at their optimal release rates, traps Band C captured 4 and 26 times, respectively, more males than trap A.
