英文摘要 | The release rates of three formulations of Z-8-dodecenyl acetate (Z-8-DDA) dispensed into rubber septa, polyethylene and teflon tubes respectively,for mating disruption of the carambola fruit borer, Eucosma notanthes (Meyrick) were determined under outdoor conditions by weighing the weight lose at weekly interval. Weight-loss measurements showed that the sex pheromone Z-8-DDA was released steadily from the rubber septum over an extended period, and its residual lure was 50.7% of the original amount after 10 weeks exposure. However, the release rate of Z-8-DDA from the polyethylene tube was initially faster and gradually became steady after 4 weeks exposure, and the residual lure was calculated to be 24.5% of the original amount after 10 weeks exposure. On the contrary, the release rate of Z-8-DDA from the teflon tube was the fastest among the three different carriers, and its residual lure was only 2.3 and 0% of the original amoung respectively, after 5 and 10 weeks exposure. In addition, The evidence shows for the 15 and 30 cm length of polyethylene tubes, their release rates of Z-8-DDA are similar, as well as, no matter their ends sealed or not, the release rate of Z-8-DDA will not be affected. |
