摘 要：
落叶松叶蜂是危害华北落叶松人工林的重要害虫,运用便携式撒布器发射3种无公害生物灭虫弹开展了防治落叶松叶蜂林间试验,结果表明,森得保6d后防效达到90%以上,阿维菌素8d后防效达到90%以上,Bt10d后防效达到80%以上,防治效果和速效性依次为森得保、阿维菌素、Bt;最佳防治期应在4龄幼虫占6.9%以下,并对非靶性生物影响小。最后指出了无公害生物灭虫弹及撒布器是一种新研制的森林病虫害防治设备,具有效率高、机动灵活、安全可靠等优点,适用于山区推广。

摘 要：
Larch Tenthredinidae is important pests against larch plantation in North China,we carried out the test in forest on using portable scatterable launching three kinds of bombs of pollution-free biological control pest to combat Larch Tenthredinidae,the results showed that the defensive efficiency of Sen exceed 90 percent after six days,the defensive efficiency of Abamectin exceed 90 percent after eight days,the defense efficiency of Bt has reached over 80 percent after 10 days,the defensive efficiency and quick result was followed by Bao Sen,abamectin,Bt;the best prevention period should be in the fourth instar larvae of below 6.9 percent,and the small impact on non-karget of biological.At last the author concluded that the pollution-free and biological control pest bombs and scatterable is a new development for the forest pest control equipment,with high efficiency,flexibility,safety and reliability advantages,the promotion applies to mountain.
