摘要
通过对施用金龟子绿僵菌前后马尾松毛虫虫口密度的T测验、节肢动物群落的垂直分布格局及群落特征参数的分析,结果表明:金龟子绿僵菌对马尾松毛虫的种群控制作用明显,对非目标无脊椎动物不具有明显的影响,并且改善了整个马尾松林节肢动物群落的多样性和稳定性。
T test of the density of Pinus massoniana caterpillars,vertical pattern of arthropod community and communities character parameters were analysed before and after applying Metarhizium anisopliae.The results showed that M.anisopliae had obvious biocontrol effect on Pinus massoniana caterpillars,but it had no impact on the non-target invertebrates apparently.The diversities and stabilities of arthropod communities in Pinus massoniana stands were improved.
