| 摘 要： | ＸＲＰ－４７３是灭幼脉类杀虫剂，试验结果表明，对柑桔潜叶蛾和柑桔木虱有较好的防治效果，对一些柑桔害虫的天敌较安全。用７０ｐｐｍＸＲＤ－４７３防治潜叶蛾１－２龄幼虫，校正死亡率为７８．７％和９３．６％，作为对比的杀灭菊酯为２２．％。用５０ｐｐｍ防治柑木虱初龄若虫校正死亡率９１．１５％，但对上述两种害虫的老龄幼、若虫效果稍差。用５０ｐｐｍ对脯食性天敌草蛉、蜘蛛、瓢虫捕螨田间施药试验，１０天后几种天敌数

| Abstract: | XRD-473 is a kind of diflubenzuron pesticide. The results of field efficacy test showed that the correct mortality with 70ppm was 98.7% and 93.6% to first instar and second instar larva of citrus leaf miner, Phyllocnistis citrella respectively.But spraying with fenvalerate as the control pesticide, the correct mortality was only 22%.The correct mortality With 50ppm was 90.5%to the younger nymph of citrus psylla, Diaphorina citri. But the efficacy to the older larva and nymph of these two pests was lower.The result of field efficucy test of XRD-473 to predacious natural enemies, ladybirds,spiders, green lacewings and predatory mites showed that the number of insect enemies was trot significantly different with ths control(water) 10 days after spraying. XRD-473 is a good prospect pesHcid) ?n the integrated management of citrus pests. |
