摘要
红脂大小蠹、松六齿小蠹、松十二齿小蠹、松八齿小蠹、果小蠹是2008年太原市滨河东西路、龙城大街、太榆路、晋祠迎宾路及动物园、玉门河等35个地段所栽植油松上暴发的主要害虫种类。小蠹虫以其隐蔽性强、繁殖速度快给防治带来困难。从物理屏障、环保角度出发,利用陶土的致密性加入胶性成分,配合渗透性药剂研制出药陶土复配水溶胶涂干技术,在试验地与高脂膜、石灰、药剂涂干进行对比试验,结果表明,药陶土复配水溶胶对小蠹虫的防治效果显著;同时进行药陶土复配水溶胶不同月份涂干试验和不同配比、涂抹厚度试验,旨在验证药陶土的防效,用于实践的推广应用。
Dendroctonus valens LeConte,Ips acuminatus Gyllenhal,Ips subelongatus Motschulsky,Ips sexdentatus Boerner and Scolytus japonicus Chapuis are dominant pest insects broke out in Chinese pine trees in 2008 in the East and the West Binhe Road,Longcheng Street,Taiyu Street,Jinci Yingbing Street,zoo and 35 road sections along Yumenhe River in Taiyuan.Dut to its rather good concealment and fast propagation,Bts's control is fairly difficult.In the control,permeatable drug chemicals and glue were combined with fine pottery clay and then spreaded over tree trunk stem.On the experiment site,comparison was conducted with the other spreading substance like lipid membrance,lime and other drugs,and the results of the technology of drug + pottery clay + glue showed remarkable control effect.In addition comparisons with the other application months and various spreading thickness were also made.
