摘　　要：[目的]为花生地下害虫大面积防治提供科学依据。[方法]采用不同用量15%乐斯本颗粒剂随花生种子穴施和花针期近根3 cm穴施,通过与高巧+普尊种衣剂组合拌种仁处理及空白区进行比较,研究15%乐斯本颗粒剂对泰州地区花生蛴螬的防治效果。[结果]15%乐斯本颗粒剂对泰州地区蛴螬具有显著的防治效果,其中花针期30 kg/hm2用量效果最佳。[结论]15%乐斯本颗粒剂花针期30 kg/hm2施药处理的效果与高巧种衣剂组合相当,但高巧组合产量较高。[Objective] To provide scientific basis for large area control of underground pest of peanut. [Method] Different doses of 15% chlorpyrifos granules with 3 cm cave peanut seed and flowering-pegging stage of peanut were used and compared with Gaucho＋Puzun seed coating agent mixed seed kernel treatment and the control. The prevention and control effects of 15% chlorpyrifos granules on white grub of peanut in Taizhou region were studied. [Result] 15% chlorpyrifos granules had significant prevention and control effects on white grub of peanut in Taizhou region. The effects of 30 kg/hm 2 was the best in flowering-pegging stage of peanut.[Conclusion] The control effect of 30 kg/hm 2 15% chlorpyrifos granules in flowering-pegging stage was the same with that of the combination of Gaucho seed coating agent, but the yield of Gaucho was higher.
