摘　　要：为寻找轻简、高效、安全控制花生主要害虫蛴螬的技术模式,连续4年对六种防治方法进行了评价,对解决蛴螬防治难题、提高防治技术水平提供参考和依据。辛硫磷微囊悬浮剂(辛硫磷CS)+性诱剂及毒死蜱微囊悬浮剂(毒死蜱CS)+性诱剂的防虫效果、保果效果、产量及增产率呈逐年增加趋势,连续使用4年后,两混剂与单独使用辛硫磷CS或毒死蜱CS的各指标间无显著差异。辛硫磷CS+性诱剂及毒死蜱CS+性诱剂对蛴螬的防治效果分别为82.51%和82.4%,保果效果分别为79.99%和79.46%。不同施药方式下,花生产量均有所增长,但各处理间稍有差异。辛硫磷CS+性诱剂配合使用,产量较高,达到204.5kg/667m2,增产23%。辛硫磷CS+性诱剂或毒死蜱CS+性诱剂两混剂的农药用量均为250g/667m2,分别比单独使用两化学农药低100g/667m2;成本为37元/667m2,比单独使用两化学农药高2元/667m2。在不降低防治效果的前提下,前者能降低农药用量,符合国家两减趋势。The study tried to find the suitable reagents and methods for prevention and control of white grub.6application methods were carried and evaluated in peanut field for 4years.During the 4years,the grub control infect,peanut pods preservation,peanut-yield and yield increasing rate under the treatment of phoxim CS＋sex lure or chlorpyrifos CS＋sex lure were continuously elevated.The control indexes of phoxim CS＋ sex lure or chlorpyrifos CS＋ sex lure showed no significant differences to phoxim CS or chlorpyrifos CS.The grub control effect of phoxim CS＋sex lure or chlorpyrifos CS＋ sex lure was 82.51% and 82.4%,respectively.The peanut pod preservation effect of phoxim CS＋ sex lure or chlorpyrifos CS＋ sex lure was 79.99% and 79.46%,respectively.Peanut yield were all increased under different treatments.Peanut yield under the treatment of phoxim CS＋sex lure was higher than other treatments,which was 204.5kg/667m2,with the yield increasing rate as 23%.The dosage of phoxim CS＋ sex lure or chlorpyrifos CS＋ sex lure were both 250g/667m2,which were 100g/667m2 lower than phoxim CS or chlorpyrifos CS.The cost was phoxim CS＋ sex lure or chlorpyrifos CS＋ sex lure were both 37yuan/667m2,which were 2yuan/667m2 more expensive than phoxim CS or chlorpyrifos CS.The former methods with higher control effect and lower pesticide dosage were much worthy to be promoted.
