16种杀虫剂对稻飞虱的田间防治效果

The Control Effect of 16 Insecticides Against Nilaparvata lugens

为进一步明确现有杀虫剂对水稻稻飞虱的效果。在大田中,以喷雾施药法对16种杀虫剂进行了防治稻飞虱的田间试验。结果表明:用药7d后,对稻飞虱控制效果最好的是氟虫睛,达96.6%,最差的是啶虫脒,仅24.9%。16个杀虫剂中防治效果≥90%的有氟虫腈、吡虫啉、噻嗪酮及辛硫磷4种;防治效果达80%～90%的有仲丁威、毒死蜱和异丙威3种;防治效果为70%～80%的有5种,防治效果在60%～70%的及防治效果<60%的各有2种。因此,目前能有效控制稻飞虱为害的杀虫剂仍然是吡虫啉、噻嗪酮、仲丁威EC和异丙威,以及氟虫腈、毒死蜱及辛硫磷。

To understand the control effect of imidacloprid preparations against NiIaparvata lugens, 16 insecticides were tested in rice through field spray. The resuhs showed that, 7 days after single spray, fipronil got the maximum control effect of 96.6% and asetamiprid got the minimum control effect of 24.9%. Among the 16 insecticides tested, fipronil, imidacloprid, buprofezin and phoxim got control effect above 90%; fenobucarb, chlorpyrifos and isoprocarb were between 80%-90%; 5 kinds were 70%-80%, 2 kinds were 60%-70% and 2 kinds were below 60%. It was concluded that, imidacloprid, buprofezin, fenobucarb, and isoprocarb, as well as fipronil, chlorpyrifos, and phoxim can effectively prevent the attack by Nilaparvata lugens in rice.
