用7种杀虫剂对云南云杉长足大蚜若虫进行室内毒力测定,5种杀虫剂开展田间防治试验,结果表明:供试杀虫剂对云南云杉长足大蚜的毒力大小依次为:0.5%藜芦碱可溶性液剂>1%苦参碱可溶性液剂>4.5%联菊·啶虫脒乳油>4.5%高效氯氰菊酯乳油>10%阿维·毒死蜱乳油>4%甲维.氟铃脲微乳剂>30%吡虫啉·噻嗪酮乳油。在田间防治若蚜时,施药24h后,0.5%藜芦碱可溶性液剂0.025%药液、1%苦参碱可溶性液剂0.033%药液和4.5%联菊·啶虫脒乳油0.017%药液防治效果均达95%以上。
Seven kinds of insecticides were used to determine the indoor toxicity of the spider mites in Yunnan Spruce. Five insecticides were tested in field. The results showed that the virulence of the tested insecticides to Spider mites As follows: 0.5% veratridine soluble liquid> 1% matrine soluble liquid> 4.5% lianryside / acetamiprid EC> 4.5% beta-cypermethrin> 10% AVV chlorpyrifos> 4% Benthonil microemulsion> 30% imidacloprid · buprofezin EC. In the field of prevention and treatment of aphids, after application of drug 24h, 0.5% veratridine soluble solution 0.025% solution, 1% matrine soluble solution 0.033% liquid and 4.5% Lian Chuan · acetamiprid EC 0.017% drug Liquid prevention and control effects are up to 95%.
