| 摘 要： | 目的观察使用不同剂量甲基嘧啶磷现场灭蚊幼效果,为今后灭蚊幼提供科学依据。方法选择实验场地同时设对照区并测量其水体体积,分别按0.012、0.02、0.1、0.2 g a.i/m3剂量施药,定期用勺捞法分别观察其密度。结果施药剂量在0.012 g a.i/m3时,施药后1~14 d杀灭率为63.03%~92.13%;在0.02g a.i/m3时,施药后1~26 d杀灭率为94.93%~99.45%;0.1 g a.i/m3时,施药后1~30 d杀灭率为75.52%~100%;在0.2 g a.i/m3时,施药后1~16 d杀灭率为74.15%~100%。结论实验证明,甲基嘧啶磷是控制蚊虫孳生的一种良好的有机磷杀虫剂。但在现场使用时,应根据水体污染状态选择合适的剂量,以达到预期效果。

| Abstract: | Objective To study the efficacy of different dosages of actellic against mosquito larvae in field and provide scientific data for controlling mosquito larvae in future. Methods The experimental sites(including treatment and control area)were selected and the volume of body were measured.Different dosages of actellic(0.012,0.02,0.1,0.2 g a.i/m3) were sprayed respectively into the experimental spots.Assessment of pretreatment and post-treatment density was carried out periodically with the ladle catching meth... |
