利用蜘蛛防治稻飞虱的技术及防效研究

Control Effect on Rice Planthopper by Using Spider

为测定应用人工饲养的蜘蛛防治稻飞虱的防治效果及实施该技术的可行性,项目组连续3 a人工饲养并释放蜘蛛,测定了蛛虱比、稻株的被害情况等指标,结果表明,以5 m2为单位,放蛛50、80、150三个不同密度的粽管巢蛛,10 d后防效均可达到84%以上,效果显著。

In order to validate feasibility of control effect on rice planthopper by using spider, the project team hand-rearing and release spider to validate percentage of spider-planthopper and affected plant, the result indicated that clubiona japonicola which density were 50, 80, 150 can achieve better control effect over 84%In ten days based on 5 m2 unit.
