目的了解滞留喷洒和投放胶饵对农贸市场蟑螂的防治效果,为指导防治提供科学依据。方法选择2家农贸市场分别用1%氟虫胺和0.05%氟虫腈胶饵进行防治,另选择4家农贸市场采用滞留喷洒方法进行灭蟑,采用GB/T 23795-2009中的粘捕法调查施药前后不同时间的密度。结果 2家使用胶饵防治的农贸市场现场施药后3 d,蟑螂密度平均下降率达到60.0%以上,经连续补药20 d后下降率达到94%以上,而使用滞留喷洒的4家农贸市场蟑螂密度没有降低。结论 1%氟虫胺和0.05%氟虫腈胶饵对农贸市场蟑螂有较好的防治效果,而滞留喷洒对农贸市场蟑螂防治效果较差。
Objective To understand the prevention and control effect of stagnant spray and plastic bait on the market of cockroaches in order to provide a scientific basis for prevention and control. Methods Two farmer’s markets were selected for prevention and control with 1% Sulfluramid and 0.05% Fipronil, respectively. In addition, four farmer’s markets were selected to eliminate cockroaches by sticking method. The sticking method in GB / T 23795-2009 Investigate the density at different times before and after application. Results The average drop rate of cockroach density reached 60.0% 3 days after on-the-spot pesticide application in two farmers’ markets using rubber bait, and the rate of descending rate reached 94% after 20 days of continuous drug application. However, No decrease in density. Conclusion 1% selumetamit and 0.05% fipronil gum bait on the farmers market cockroaches have a better control effect, and the residual spray on the farmers market cockroaches control less effective.
