摘要
樟叶蜂是香樟树的主要食叶害虫,其幼虫取食香樟树嫩叶,危害香樟及幼苗。2014年在福建省沙县采用1.1%苦参碱粉剂22.5 kg/hm2喷粉和1%苦参碱可溶性液22.5 ml/hm2喷雾方式,在圃地田间和香樟行道树对樟叶蜂3龄幼虫进行防治试验。结果表明:药后2 d,2种药剂防治效果均可达90%以上,且二者之间无显著差异。说明这2种药剂均具有高效杀虫效果,可在樟叶蜂危害时应用。
Mesonura rufonota Rohwer is a leaf-eating pest ofCinnamomum camphora （L.） Presl. Its larvae feed on tender leaves of Cinnamomum camphora and cause danger. In 2014 1.1% matrine powder 22.5 kg/hm^2 and 1% soluble matrine liquid 22.5 ml/hm^2 were used to control the 3 instar larvae in the nursery field and on roadside camphor tree in Shaxian county, Fujian province. The results showed that： the control efficiencies of the two chemical agents reached more than 90%; and there were no significant difference between the two agents. It showed that 2 kinds of agents are highly effective insecticides, and can be used to control the sawfly.
