【摘要】 目的测定氟氯氰菊酯处理土壤对台湾乳白蚁和黄胸散白蚁的抗穿透效果。方法将药液混在土壤中,测定土壤对白蚁穿透的阻止效果。结果200 mg/L氟氯氰菊酯药液处理土壤可完全阻止台湾乳白蚁穿透5 cm长的毒土柱,但完全阻止黄胸散白蚁穿透5 cm长的毒土柱,处理土壤的药液浓度需达250 mg/L以上。结论利用5.7%氟氯氰菊酯乳油作为土壤处理剂防治白蚁时,为保证防治效果,应采用较大的浓度。更多还原

【Abstract】 ObjectiveTo determine the anti-tunneling effect of cyfluthrin on the workers of Coptotermes formosanus and Reticulitermes flaviceps.MethodsThe cyfluthrin solution was mixed into soil and the anti-tunneling effect of toxic soil on termites was evaluated.ResultsThe concentration of cyfluthrin solution retarded completely termites to pass through 5 cm length of toxic.Soil pillar was 200 mg/L for C.formosanus and 250 mg/L for R.flaviceps.ConclusionIf 5.7% cyfluthrin Ec was used in soil for termite control in practice,in order to ensure the control effect,the higher concentration of solution should be used.更多还原
