摘要
目的观察评价滞留喷洒与饵膏杀灭蟑螂的效果。方法采用粘捕法监测投药前后蟑螂密度，用蟑螂密度下降率来评价灭蟑螂效果。结果第1次灭蟑后蟑螂密度能得到迅速控制，密度下降率在50．00％～92．11％；第2次灭蟑后密度已控制在较低水平，密度下降率在98．79％～100．00％。结论通过现场灭蟑观察，证明采用滞留喷洒与饵膏杀灭蟑螂效果显著，值得推广。
Objective To observe the efficacy of residual spray and gel bait against cockroaches. Methods Adhesive killing method was applied in density investigation. Efficacy of gel bait against cockroaches was calculated by contrasting the density reduction rate. Results The cockroach density decreasing rate was from 50. 00% to 92. 11% after the first killing,and 98.79% - 100. 00% after the second killing. Conclusion The method of using residual spray and gel bait against cockroaches is of high efficacy. It should be generalized.
