吡虫啉杀蚁饵剂杀灭小黄家蚁效果及试验方法研究

目的研究蚂蚁饵剂的试验方法,并观察吡虫啉杀蚁饵剂杀灭小黄家蚁的效果。方法实验室、模拟现场和现场试验。结果 0.03%吡虫啉杀蚁饵剂对小黄家蚁的LT50为21.10h,7d死亡率100%;模拟现场4只蚁后第5天全部死亡,工蚁第6天死亡率100%;现场试验第14天小黄家蚁密度下降率为98.42%。结论采用的室内及模拟现场小黄家蚁为试虫的蚂蚁饵剂试验方法可行;0.03%吡虫啉杀蚁饵剂杀灭小黄家蚁控制居家蚁害效果良好。

Toxicity of imidacioprid baits against Monomorrium pharaonis and test methods

Objective To explore the test methods for ant bites and to determine the killing effect of imidacloprid baits against Monomorrium pharaonis. Methods Laboratory test, simulated field test and field test were carried out. Results The LT50 value of 0.03% imidacloprid baits for M. pharaonis was 21.10 h, with a 7 d mortality of 100%. In the simulated field test, all of 4 queen ants were killed at day 5, while 100% of ergates died at day 6. In the field test, the density of M. pharaonis reduced to 98.42% at the 14 day. Conclusion Using M. pharaonis as the subject, the laboratory and simulated field test were applicable for ant baits, and 0.03% imidacloprid baits had favorable killing effect against M. pharaonis, which could be used for residential termite control.
