毒饵及胶饵对旅客列车德国小蠊综合防制效果研究

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％哗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（χ^2=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（χ^2=15．499，P=O．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。

Studies on the control efficacy of poison bait and gel bait to Blattella germanica in the passenger trains

Objective To study the synthesis control effects of the poison bait and the gel bait to Blattella germanica in the passenger trains. Methods One percent acephate and 1% Yekang gel bait were applied exclusively or both were jointly used in the passenger trains. The density of B.germanica was monitored before and after treatment respectively. Results There was significant difference between the combined application of poison bait and gel bait and single application of poison bait （χ^2= 17.146, P=0.000）. The combined application of poison bait and gel bait also significantly differed compared to that of the single gel bait （χ^2= 15.499, P=0.000）. Conclusion The combined application of cockroach poison bait and gel bait had a remarkable efficacy to the fast killing of B.germanica and the maintenance of low cockroach density in the passenger trains
