[目的]初探不同剂量的吡虫啉毒饵对台湾乳白蚁的灭治效果和其对台湾乳白蚁的引诱力。[方法]利用限制活动空间的无选择取食法和供试不同剂量的毒饵的选择性取食法,分别测定吡虫啉毒饵对台湾乳白蚁的致死率和引诱率。[结果]所有剂量的吡虫啉毒饵对台湾乳白蚁都有良好的毒杀效果,致死率为100%,致死时间在18~22个观察周期(12 h)间。其中质量分数为0.04%、0.08%的吡虫啉毒饵的致死中时较长,符合白蚁群体灭治的要求,而质量分数为0.04%、0.08%、0.16%的吡虫啉毒饵对台湾乳白蚁的引诱力最强。[结论]0.04%和0.08%的吡虫啉毒饵可作为有效的白蚁防治有效手段进一步研究。
[Objective] The research aimed to study the effect of different dosages of imidacloprid bait on the killing of Taiwan’s termites and its attraction to Taiwan’s termites. [Method] The lethality and the inducing rate of imidacloprid bait on the termites were determined by the selective feeding method which limited the activity space and the selective feeding method of the bait with different dosages. [Result] All the doses of imidacloprid baits had a good toxin killing effect on Taiwan termites. The lethal rate was 100% and the lethal time was between 18 and 22 observation cycles (12 h). The mass fraction of 0.04% and 0.08% of the imidacloprid bait was longer, which was in line with the requirements of the termite community killing. The luring power of the imidacloprid bait was 0.04%, 0.08% and 0.16% Strong. [Conclusion] The imidacloprid baits 0.04% and 0.08% could be used as effective control measures for termite control.
