摘要:

为优化性信息素迷向袋的释放性能并明确其与化学防治联用对芦笋夜蛾类害虫的综合防控效果,本研究于2024—2025年开展了迷向袋释放性能测定与田间防控试验。通过调控缓释膜释放面积制备3种迷向袋(3 cm2、7 cm2、10 cm2),采用气相色谱法定期测定信息素残留量并计算日均释放速率;在江苏涟水设施芦笋田设置迷向+化学防治联用区、常规化学防治区2个处理,监测成虫诱捕量、计算迷向率,调查芦笋被害枝率,统计农药施用频次、折百用量并核算亩均生产成本、产量与投入产出比。结果表明,缓释膜释放面积与信息素日均释放速率呈正相关,释放面积为10 cm2平均释放速率最高,为5.31 mg/d;迷向与化学防治联用对两种夜蛾类害虫的迷向率均在70%以上,芦笋全生育期被害枝率显著低于常规化防区;与常规化防区相比,联用技术每月减少用药2次,化学农药折百用量减少约50%,且投入产出比为1∶2.67,优于常规化防区1∶2.26。综上,释放面积10 cm2规格迷向袋信息素释放性能稳定,与化学防治联用可实现农药减量、控害增效,适用于芦笋夜蛾类害虫的综合防控,具备良好的推广应用前景。

Abstract:

To optimize the release performance of sex pheromone mating disruption bags and evaluate the comprehensive control efficacy of their combination with chemical control against asparagus noctuid pests, a series of experiments were conducted from 2024 to 2025. Three types of mating disruption bags with release areas of 3 cm², 7 cm² and 10 cm² were fabricated by adjusting the release area of slow-release membranes. Gas chromatography was used to periodically detect residual pheromone contents and calculate the daily release rate. Two treatments, mating disruption combined with chemical control and conventional chemical control, were established in greenhouse asparagus fields in Lianshui, Jiangsu Province. We monitored the number of trapped adult moths, calculated mating disruption rates, surveyed the damaged shoot rate of asparagus, recorded pesticide application frequency and the dosage of active ingredients, and calculated the production cost, yield and input-output ratio per 667 m². The results showed that the daily pheromone release rate was positively correlated with the release area of slow-release membranes. The bag with a release area of 10 cm² had the highest average release rate of 5.31 mg/d. The mating disruption rate of the combined treatment against the two noctuid species exceeded 70%, and the damaged shoot rate of asparagus throughout the growing season was significantly lower than that in the conventional chemical control plot. Compared with the conventional chemical control area, the combined technology reduced pesticide application twice per month, with a approximately 50% reduction in the amount of active ingredient, and achieved a better input-output ratio (1:2.67) than conventional chemical control (1:2.26). In conclusion, the mating disruption bag with a release area of 10 cm² exhibits stable pheromone release performance. Combined application with chemical control can reduce pesticide usage and improve pest control efficiency, which is suitable for integrated management of noctuid pests on asparagus and has promising prospects for large-scale popularization.
