摘要
目的 观察和评价功夫菊酯杀虫剂的灭蚤效果。方法 选择 2个自然村作为灭蚤试点 ,1个自然村为对照点 ,以灭蚤前后蚤指数的变化计算灭效 ,以空白对照点蚤指数的变化校正灭蚤率。结果 使用浓度为 0 .0 3 %的试区灭蚤率为 94.66% ,校正灭蚤率为 94.2 1% ;印鼠客蚤灭蚤率为 81.3 0 % ,校正灭蚤率 79.71%。使用浓度为 0 .0 5 %的试区灭蚤率为 10 0 .0 0 % ,校正灭蚤率为 10 0 .0 0 %。结论 该杀虫剂在德宏鼠疫疫区有较好的灭蚤效果。
Objective To observe and evaluate the effect of cyhalothrin against flea.Methods To chose two natural villages as experimental units and one village as control unit. The change of flea index before and after the treatment was used to count the killing effect. The change of flea index of the control unit was used to rectify the effect of killing flea. Results The rate of killing flea in 0.03% experimental area was 94.66%. The rectified rate of killing flea was 94.21%. The rate of killing xenopsylla cheopis was 81.30%.The rectified rate of killing flea was 79.71%. The rate of killing flea with 0.05% was 100.00%. The rectified rate of killing flea was 100.00%. Conclusion The cyhalothrin had better effect against the flea in the plague endemic area of Dehong prefecture.
