摘要
沙棘是重要的防风固沙和水土保持树种,同时沙棘果实具有重要的经济价值。沙棘绕实蝇是钻蛀性危害沙棘果实的重要检疫害虫。为给将来的无公害防治研究打下基础,对沙棘绕实蝇在内蒙古磴口县的发生与危害进行了初步调查。结果表明:沙棘绕实蝇在当地发生严重,1年发生1代,以预蛹越冬,幼虫对沙棘果实的危害率在93%以上。为了采用耕作等措施除治害虫的茧蛹,调查了沙棘绕实蝇茧蛹在沙棘林地土层内的分布规律,发现茧蛹在土壤内的水平分布只与投影上方是否有沙棘果实有关,且大部分均分布在地表深度为6 cm内的沙土层内。
Hippophae rhamnoides is an important tree the fruits have important economic value. Rhagoletis fruits of Hippophae rhamnoides. The occurrence and species for sand fixation and soil and water conservation, and batava obseuriosa is an important quarantine pest of damaging damage caused by Rhagoletis batava obseuriosa in Dengkou, Inner Mongolia have been investigated in order to lay a foundation for harmless control in future. The results show that Rhagoletis batava obseuriosa occurred in local area seriously with one generation a year and overwintering as prepupa. And the damage rate of larva on fruits of Hippophae rhamnoides is more than 93%. The distributing law for the pupae of Rhagoletis batava obseuriosa has been investigated in soil layer of Hippophae rhamnoides forestland. It has been found that the fruits of Hippophae rhamnoides above the soil can influence the horizonal distribution of the pupae of Rhagoletis batava obseuriosa in soil, and most of the pupae of Rhagoletis batava obseuriosa distribute in the soil layer from 0 to 6 cm.
