痣鳞鳃金龟的生物学特性与防治

BIOLOGICAL CHARACTERISTICS OF LEPIDIOTA STIGMA AND ITS CONTROL

痣鳞鳃金龟二年发生一代 ,此虫在砂质土壤的林地密度大 ,为害严重。造林时在每株根际施 5g 3 %呋喃丹颗粒剂 ,可有效地控制此虫的危害并兼治其它地下害虫和造林初期的食叶害虫。

Lepidiota stigma annually produces two generations. The density of this pest is often high in plantations with sandy soils, which lead to heavy damage to the growth of trees. During planting, putting 5 g of granular carbofuran (3%) at the bottom of trees would effectively control the damage of Lepidiota stigma .It is a effective way to control other underground insects and foliage eaten insects of young trees as well.\;
