Abstract:

A Y-tube apparatus was developed for quantitative bioassay of the synthetic sex pheromone of the cabbage looper, Trichoplusia ni (Hübner). When 3- to 7-day-old (inclusive) male cabbage looper moths were used, the attractive concentration for 50% response (AC₅₀) was 1.08µg pheromone on filter paper. Based on the dissipation rate of 5µg on filter paper, the actual concentration of pheromone in the airstream at AC₅₀ was calculated to be about 91 ng/m³ air. No increase in response was noted between 5 and 5000µg
