摘要: 稻水象甲是一种检疫性害虫,近年来在宁夏地区发生频繁,为害面积持续扩大,严重影响当地水稻生产和贸易。本研究旨在筛选出既适合当地防控需求又具有低毒性、低残留性和高效能的防治药剂。通过田间试验对比了几种化学与生物农药对稻水象甲防控效果。结果表明,氯虫苯甲酰胺的防效始终最高,药后1 d达到63.98%,药后15 d更是达到91.6%的防效,其速效性和持效均优于其他几种药剂。防效次之的是乙基多杀菌素,15 d防效达到86.31%。而阿维菌素和除虫菊素15 d防效也能达到80%以上,并且有一定的速效性。白僵菌对稻水象甲15 d的防效为76.8%,而且其防效持续上升。氯虫苯甲酰胺、乙基多杀菌素、白僵菌、除虫菊素、阿维菌素这5种农药,对稻水象甲防效较好,而且白僵菌、除虫菊素、阿维菌素属于生物农药,具有较高的推广价值。

Abstract:

Rice water weevil (Lissorhoptrus oryzophilus) is a quarantine pest that has occurred frequently in Ningxia in recent years, with its harmful area continuing to expand, seriously affecting local rice production and trade. The current focus of research and development is to select Lissorhoptrus oryzophilus control agents that are suitable for local prevention and control, with low toxicity, low residue, and high control efficiency. The study selected several chemical and biological pesticides with excellent pest control effects, and verified their effectiveness in controlling Lissorhoptrus oryzophilus through field experiments. Through field experiments, the results showed that the control effect of chlorantraniliprole was always the highest, reaching 63.98% on the first day after treatment, and 91.6% on the 15th day after treatment. Its rapid and sustained effectiveness were superior to other pesticides. The second most effective fungicide was spinetoram, with a 15 day efficacy of 86.31%. Abamectin and pyrethrin could also achieve a control effect of over 80% after 15 days, and had a certain degree of quick effect. The control effect of Beauveria bassiana on Lissorhoptrus oryzophilus for 15 days was 76.8%, and its control effect continued to increase. The five pesticides, chlorantraniliprole, spinetoram, Beauveria bassiana, pyrethrin, and abamectin, have good control effects on Lissorhoptrus oryzophilus. Moreover, Beauveria bassiana, pyrethrin, and abamectin belong to biopesticides and have high promotion value.
