【摘要】 采用高效氯氰菊酯EC作为防治药物,进行毒饵诱杀、混沙触杀以及蚁巢浇灌3种方法防治红火蚁的试验。结果表明:用4.5%高效氯氰菊酯EC作防治药物时,灌巢触杀的效果最佳,混沙触杀次之,毒饵诱杀最差。灌巢触杀药后第5天,蚁巢全部被杀灭,减退率高达100%。在红火蚁的化学防治实践过程中,高效氯氰菊酯EC可作为一种红火蚁的灌巢触杀剂。更多还原

【Abstract】 The efficacy ofβ-cypemethrin(β-CP)4.5%EC against the red imported fire ant,Solenopsis invicta Buren was studied through drenching,casting toxic sand and toxic baits.Results showed that the most effective form was mound drench with the solution ofβ-cypemethrin 4.5%EC;and theβ-CP toxic sand was more effective thanβ-CP toxic baits.Five days after drench treatments,all the treated colonies were completely killed.It was suggested that β-cypemethrin 4.5%EC could be a contact insecticide for the fire ant mound drench.更多还原
