目的 研究 15 %吡·氯乳油对台湾乳白蚁、黑胸散白蚁的共毒系数和防治效果。方法 采用毒力测定、击倒法 (药膜法 )、土壤法和木材试块接触法。结果 15 %吡·氯乳油对台湾乳白蚁致死有明显的增效作用 ,共毒系数达 2 16 .88,0 .15 %以上浓度对台湾乳白蚁、黑胸散白蚁的击倒速度很快 ,台湾乳白蚁、黑胸散白蚁不能穿越用 0 .15 %浓度处理过的土壤 ,用 0 .15 %以上浓度处理过的木材对白蚁有很强的抗蛀能力。结论 15 %吡·氯乳油对台湾乳白蚁、黑胸散白蚁有很好的防治效果 ,可在白蚁防治上推广应用。
Objective To study the co-toxicity coefficient and the control effect of 15% pyrithione against termites and black-throated termites of Taiwan. Methods Toxicity determination, knockdown method (membrane method), soil method and wood test block contact method. Results 15% of the chlorine · chlorine EC had a synergistic effect on the death of Taiwan’s termites, the co-toxicity coefficient reached 2 16.88,0. The concentration of 15% Taiwan termites, black thompson termites can not cross the soil treated with 0.15% concentration, with 0.15% concentration of wood treated termites have a strong anti-moth ability. Conclusion 15% of the chlorine-chlorine EC has good control effect on the white termite and black-throated termites of Taiwan, and can be widely applied in termite control.
