摘要/Abstract

摘要： 为筛选高毒农药替代药剂，采用Potter喷雾法测定了8类29种杀虫剂对广西南宁和江苏南京稻纵卷叶螟3龄幼虫的室内毒力。这8类杀虫剂的毒力顺序为：抗生素类杀虫剂≥苯基吡唑类杀虫剂≥噁二嗪类杀虫剂≥昆虫生长调节剂类杀虫剂≥有机磷酸酯类杀虫剂、拟除虫菊酯类杀虫剂≥有机氯类杀虫剂≥沙蚕毒素类杀虫剂。甲氨基阿维菌素苯甲酸盐（甲维盐）对两地区稻纵卷叶螟3龄幼虫的触杀毒力最高，其LC50值介于0.2~0.8 mg/L；氟虫腈、茚虫威、呋喃虫酰肼、丁烯氟虫腈、虫酰肼、氟啶脲和氟铃脲的LC50值介于1.8~53 mg/L。推荐对稻纵卷叶螟毒力最高的10种新型杀虫剂（甲维盐、依维菌素、阿维菌素、氟虫腈、茚虫威、呋喃虫酰肼、丁烯氟虫腈、虫酰肼、氟啶脲、氟铃脲）和一些有机磷杀虫剂（喹硫磷、辛硫磷、丙溴磷、毒死蜱、哒嗪硫磷）作为高毒农药替代的候选药剂进行大田药效试验。此外，还讨论了稻纵卷叶螟的药剂防治措施。

Abstract: To screen alternative insecticides for controlling the rice leafroller, Cnaphalocrocis medinalis(Guenée), the toxicities of 29 insecticides belonging to 8 classes against the thirdinstar larvae of the rice leafroller collected from Nanning City, Guangxi Zhuang Autonomous Region and Nanjing City, Jiangsu Province, China were measured by the Potterspraying method. The toxicity levels of the eight classes insecticides were as follows: antibiotic insecticides≥phenyl pyrazole derivative insecticides≥oxadiazine insecticides≥ insect growth regulator insecticides≥organophosphorus insecticides, pyrethroids insecticides≥organochlorine insecticides≥nereistoxin insecticides. Emamectinbenzoate had the highest toxicity against the thirdinstar larvae of the rice leafroller, with LC₅₀ ranging from 0.2 to 0.8 mg/L; while the LC50 of fipronil, indoxacarb, JS118, butylenefipronil, tebufenozide, chlorfluazuron and hexaflumuron were from 1.8 to 53 mg/L. Ten novel insecticides (i.e. emamectinbenzoate, ivermectin, abamectin, fipronil, indoxacarb, JS118, butylenefipronil, tebufenozide, chlorfluazuron, hexaflumuron) and a few organophosphates (i.e. quinalphos, phoxim, profenofos, chlorpyrifos, pyridaphenthion) were recommended to further field trials. Furthermore, the management strategies of the rice leafroller were discussed.
