外来入侵害虫稻水象甲在宁夏发生及田间防治效果初探
Preliminary Study on Occurrence and Field Control Effects of Invasive Pest Lissorhoptrus oryzophilus in Ningxia
摘要
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.关键词
