目的观察灭蟑毒饵、胶饵联合应用对旅客列车德国小蠊的综合防制效果。方法采用1%乙酰甲胺磷灭蟑毒饵粉单独施放、1%晔康灭蟑胶饵单独施放以及2种药物联合应用于旅客列车,进行灭前及灭后蜚蠊密度监测。结果毒饵、胶饵联合应用与单独使用毒饵进行比较,差异有统计学意义(χ2=17.146,P=0.000),毒饵、胶饵联合应用与单独使用胶饵进行比较,差异也有统计学意义(χ2=15.499,P=0.000)。结论毒饵、胶饵联合应用对快速杀灭旅客列车德国小蠊,并持久保持德国小蠊低密度具有显著效果。
Objective To observe the integrated control effect of cockroach-killing bait and gel bait on German cockroach in passenger trains. Methods 1% acephate cockroach bait powder was applied alone, 1% Ye Kang cockroach rubber bait alone and two kinds of drugs were jointly applied to passenger trains for pre-off and off cockroach density monitoring. Results The combined use of bait and gel bait was statistically significant (χ2 = 17.146, P = 0.000). The combination of bait and gel bait compared with single use of bait, the difference was also statistically significant (χ2 = = 15.499, P = 0.000). Conclusions The combined application of bait and bait has a significant effect on quickly killing German cockroach in passenger trains and maintaining the low density of German cockroach for a long time.
