近年来,大袋蛾(布袋虫)在我省猖獗成灾。虽经大力防治,但未制止其扩散蔓延。主要原因是:灾害分布范围广、虫口密度大、个体生殖繁育力强,加上树木高纵挺拔,现采取的根部注入内吸剂、叶面喷洒化学农药、手工摘袋除虫等防治措施均不易根除,难免有漏株、漏喷、漏虫现象。因此,虽投入了大量人力、物力,终因防治不彻底而功亏一篑,致使害虫再度成灾,为此,在进行化学防治和人工摘袋的同时,辅以生物防治是十
In recent years, the big bag moth (Bugs insects) rampant disaster in our province. Despite vigorous prevention and control, but did not stop its spread. The main reasons are: a wide range of disaster distribution, population density, individual reproductive and reproductive power, coupled with tall tree vertical and vertical pull, now take the root into the endosiloxane, foliar spray chemical pesticides, manual removal of insects and other measures are Not easy to eradicate, it is inevitable that leakage strains, leakage spray, leftover phenomenon. Therefore, although a great deal of manpower and material resources have been put into operation, due to the incomplete prevention and treatment, the pests will be disastrous again. Therefore, while carrying out chemical prevention and artificial removal of bags, supplemented by biological control is ten
