杀虫单和杀虫双联合使用对草鱼车轮虫病的防治效果

Study on Control Effect of Combined Use of Monosultap and Dimehypo on Trichodiniasis of Grass Carp

[目的]研究杀虫单和杀虫双联合使用对草鱼车轮虫病的防治效果。[方法]将杀虫单和杀虫双与环烷酸铜、氯化钠、壬基酚聚氧乙烯醚、聚氧乙烯失水山梨醇单油酸酯、十二烷基硫酸钠、壬基酚聚氧乙烯醚硫酸钠、月桂氮酮按不同比例联合配比,用甲醇和水将其充分混合后制成液体药物,观察其对草鱼车轮虫的杀虫效果。[结果]当杀虫单和杀虫双的含量分别为15.5%和34.0%时,按10 mg/m L的剂量对车轮虫作用24 h后其杀虫效果达100%,并且在不同用药浓度下其混合药物的杀虫效果要显著高于其他组。[结论]将杀虫单和杀虫双2种药物联合使用可以达到最佳的杀虫效果,研究结果可为水产养殖中寄生虫病的防治提供用药参考。

[Objective]To study the control effects of combined use of monosultap and dimehypo on trichodiniasis of grass carp.[Method]Monosultap and dimehypo were mixed with copper naphthenate,sodium chloride,nonylphenol polyoxyethylene ether,polyoxyethylene sorbitan monooleate,sodium dodecyl sulfate,nonylphenol polyoxyethylene ether sodium sulfate and l-dodecylazacycloheptan-2-one in different mixing proportions to prepare liquid drugs after they were fully mixed with methanol and water. And their insecticidal effect on Trichodina sp. in grass carp was observed.[Result] When the contents of monosultap and dimehypo were 15. 5% and 34. 0% respectively,the insecticidal effect reached 100%after they were conducted on Trichodina sp. at a dose of 10 mg/m L 24 h. The insecticidal effect of mixed drugs at different concentrations was significantly higher than that in other groups.[Conclusion]The combined use of monosultap and dimehypo could achieve the best insecticidal effect,and the research could provide medication reference for the prevention and control of parasitosis in aquaculture.
