摘要
2016年在福建省沙县选用4种植物源杀虫剂,对毛竹林下套种的多花黄精上的豆芫菁成虫进行室内毒力测定、野外防治试验。室内毒力测定结果表明:5%桉油精可溶液剂、4%鱼藤酮乳油、1.2%烟碱·苦参碱乳油、1%苦参碱可溶液剂对豆芫菁成虫的LC50分别为3.9、1.32、0.583、0.279 mg·L^(-1),4种植物源杀虫剂对豆芫菁成虫均有毒性,以1%苦参碱可溶液剂对豆芫菁成虫毒性最强。野外防治试验结果表明:用药3 d后,4种药剂防治效果均可达90%以上,其中2种苦参碱类药剂防治效果最佳使用倍数均为1500倍;5%桉油精可溶液剂林间防治最佳使用倍数为1000倍;4%鱼藤酮乳油林间防治最佳使用倍数为1200倍。供试的4种药剂均可以作为防治豆芫菁成虫的无公害药剂。
In 2016 in Fujian Province, Shaxian County, with 4 kinds of botanical insecticides on bamboo under interplanting Polygo- nature cyrtonema on Epicauta gorhami adult field control test, toxicity test. The indoor toxicity test results showed that：5% cineole solution,4% rotenone EC, 1.2% matrine nicotine missible oil, matrine 1% LC50 solution of Epicauta gorhami adults were 3.9, 1.32,0. 583,0. 279 mg L- 1 ,4 kinds of botanical insecticides on Epicauta gorhami are toxic to adults, 1% matrine the strongest so- lution of Epicauta gorhami adult toxicity. Field test results showed after 3 days ,4 kinds of chemical control effect was up to 90%, of which 2 kinds of matrine type chemical control effect is the best, the best use of multiples were 1500 times;5% eucalyptol solution in the forest is best to use a multiple of 1000 times;the control oil milk 4% rotenone best use ratio 1200 times. 4 kinds of chemicals can be tested as a pollution-free chemical control of Epicauta gorhami aduhs.
