摘　　要：研究了植物挥发性有机化合物α-蒎烯对重要储粮害虫杂拟谷盗成虫的控制作用。结果表明,α-蒎烯对杂拟谷盗成虫具有较强的驱避、触杀和熏蒸作用。其驱避作用随着处理时间延长和处理剂量的增加而增强,在α-蒎烯与乙醇按体积比1.6∶1处理剂量下处理72 h后驱避率达到90.91%,驱避活性达到Ⅴ级。其触杀作用随着处理时间延长和处理浓度增加而显著增强,α-蒎烯在3.00μL/cm2处理浓度下处理48 h后触杀作用校正死亡率即达到100%。α-蒎烯在10、20、40、80μL/L处理浓度的熏蒸作用平均校正死亡率分别达到94.96%、99.16%、100%和100%。The controlling effect of α-pinene,a plant-derived organic volatile,against Tribolium confusum adults,an important stored-grain insect,was investigated.Results：α-pinene possesses extremely strong repellent,contact and fumigation activities against T.confusum adults.The repellent activity increases with increasing exposure time and treatment dosage,and the percentage repellency of α-pinene reaches 90.91% with repellency class V after 72 h treatment at a volume proportion of α-pinene and ethanol 1.6 ∶ 1.The contact toxicity also significantly enhances with increasing exposure time and treatment concentration,and the corrected percentage mortality reaches 100% after 48 h exposure time at concentration 3.00 μL/cm2.The mean corrected percentage mortality of fumigation toxicity of α-pinene at 10,20,40,80 μL/L reaches 94.96%,99.16%,100% and 100%,repectively.
