1噻虫啉微胶囊粉剂林间防治松褐天牛试验

摘要

林间用1%噻虫啉微胶囊粉剂进行防治松褐天牛试验。结果表明,该药剂对松褐天牛有较强的杀灭效果,且持效期达30 d以上。在喷洒1%噻虫啉微胶囊粉剂的林区,平均每个诱捕器的成虫诱捕量为32.4头,诱木上平均成虫产卵刻槽数为19.6个/m2;而在对照区,平均每个诱捕器的成虫诱捕量为93.8头,是喷药区的2.83倍,平均刻槽数达191.02个/m2,是喷药区的9.75倍。施药的相对防治效果可达86.3%。%The effect of 1% Saichonglin powder was measured to control Monochamus alternatus in Pinus massoniana plantations in Ji＇an County,Jiangxi Province.Results showed that this pesticide has strong killing effect on Monochamus alternatus for 30 d persistence.Only an average of 32.4 JPS adults was captured in each trap in the sprayed pine plantations while 93.8 adults captured in the CK.An average of 19.6 ovi-position holes digged by the JPS adults per m2 were found in the baited woods of the sprayed plantations but 191.02 holes in the CK.Applying in the plantations,the relative control effect was achieved by 86.30%.
