Abstract:
【Abstract】 Objective To study the evaluation methods of larvicides registration and field test. Methods Larvae were collected from breeding sites in the external environment or adult mosquitoes were trapped to oviposit in man-made areas. Results The relative population index (RPI) of larvae from breeding sites was under 5 after treatment by 1% temephos granules for 4 weeks, which had a good control effect. RPI of larvae from wasted tyres was also less than 5 after treatment for 4 weeks, while it was under 10 after treatment for 3 weeks in cement pool. Conclusion The field control effect and registration of quick-acting insecticides could be evaluated by the above mentioned two methods.

【摘要】 目的 研究灭蚊幼剂获证登记和现场评价方法。方法 外环境孳生地采集幼虫和人为孳生地诱卵孳生幼虫的现场试验方法。结果 现场试验用药为1%双硫磷颗粒剂;孳生地采集幼虫试验方法, 4周内相关密度指数(RPI)<5, 控制效果良好, 且蚊虫在试验场所能形成种群; 人为创建孳生地中的轮胎法4周内 RPI<5, 水泥池法3周内 RPI<10。结论 2种试验方法均可作为速效灭蚊剂的现场效果评价或获证登记评价的试验方法。
