目的观察绿叶杀蟑胶饵现场防制德国小蠊的效果。方法按照实际施药面积以0.3g/m2的剂量,将绿叶杀蟑胶饵以注射的方法,间断性点状施药于德国小蠊出没处及隐蔽处,观察施药前后德国小蠊密度变化,评价杀灭效果。结果施药前现场德国小蠊平均密度(只/张)为11.2,施药后1d、3d、5d、10d、30d平均密度(只/张)分别为6.2、2.0、0.7、0.1、0.4,平均密度下降率分别为44.6%,82.1%,93.8%,99.1%,96.4%。结论绿叶杀蟑胶饵杀灭率高,持效期长,适用于防制德国小蠊,值得推广应用。
Objective To observe the effect of green leaf-killing gel bait on-site control of German cockroach. Methods According to the actual application area of 0.3g / m2 dose, the green leaf to kill cockroach gel bait injection by intermittent punctatus applied to the German cockroach infested and hidden place, before and after treatment to observe the changes in the density of German cockroach , Evaluation kill effect. Results The average density (only / sheet) of German cockroach was 11.2 before application. The average density at 1d, 3d, 5d, 10d and 30d after application was 6.2, 2.0, 0.7, 0.1 and 0.4 respectively The density reduction rates were 44.6%, 82.1%, 93.8%, 99.1%, 96.4% respectively. Conclusion Green leaf kill cockroach gel bait kill rate, long duration, suitable for the control of German cockroach, it is worth promoting the application.
