10种杀虫剂对红棕象甲高龄幼虫的毒力测定

The efficacy of 10 pesticides against red palm weevil Rhynchophorus ferrugineus(Oliver)

为了筛选出对红棕象甲高龄幼虫防治较好的杀虫剂,在室内采用浸泡法测定了啶虫脒、三唑磷等10种杀虫剂对红棕象甲高龄幼虫的毒害作用。结果表明:啶虫脒对红棕象甲高龄幼虫致死作用最强,其次是三唑磷、高效氯氰菊酯和敌敌畏3种杀虫剂,除虫脲、毒死蜱、阿维菌素、吡虫啉、甲氰菊酯和高效氯氟氰菊酯对红棕象甲高龄幼虫的致死效果较差;啶虫脒、三唑磷、高效氯氰菊酯和敌敌畏这4种杀虫剂可能在田间防治红棕象甲有较好的应用前景。

In order to screen out the pesticides for controlling red palm weevil Rhynchophorus ferrugineus（Oliver） effectively,the toxicity of 10 pesticides （emamectin benzoate etc.） to red palm weevil was determined.The results showed that acetamiprid,triazophos,beta-cypermethrin and DDVP were much more efficacy than diflubenzuron,chlorpyrifos,imidacloprid,fenpropathrin and lambda-cyhalothrin to larvae in laboratory conditions,which showed that acetamiprid,triazophos,beta-cypermethrin and DDVP may have efficacious control to red palm weevil in the fields.
