摘　　要：灯光诱捕是一种环境友好的害虫监测方法。深入了解不同波长和光强的发光二极管(LED)光源对储粮害虫趋向性的影响可以提高灯光诱捕效果。在试验室条件下研究了米象、赤拟谷盗、烟草甲、锈赤扁谷盗、杂拟谷盗和玉米象等6种常见储粮害虫成虫对不同波长和强度的LED光的趋性。研究表明,米象对波长590 nm、光照强度为170 lx的LED灯趋光率最高,达到81.11%;赤拟谷盗对波长520 nm、光照强度为120 lx的LED灯趋光率最高,达到92.22%;烟草甲对波长460 nm、光照强度170 lx的LED灯趋光率最高,达到77.78%;锈赤扁谷盗对波长356 nm的LED灯趋光率最高,达到93.33%;杂拟谷盗对波长460 nm、光照强度120 lx的LED灯趋光率最高,达到84.44%;玉米象对波长365 nm的LED灯趋光率最高,达到88.89%。研究结果对科学利用储粮害虫趋光性开展害虫综合治理具有参考价值。Light trapping is an environmentally friendly pest insect monitoring method.Deeply understanding the influence of different wavelengths and light intensities of light source on the phototaxis of stored grain insects is very helpful for improving light trapping effectiveness.Thus,the phototaxis of adults of Sitophilus oryzae(Linnaeus)(Coleoptera:Curculionidae),Tribolium castaneum(Herbst)(Coleoptera:Tenebrionidae),Lasioderma serricorne(F.)(Coleoptera:Ptinidae),Cryptolestes ferrugineus(Stephens)(Coleoptera:Laemophloeidae),Tribolium confusum(Jacquelin du Val)(Coleoptera:Tenebrionidae)and Sitophilus zeamais(Motschulsky)(Coleoptera:Curculionidae)to LED lights of different wavelengths and intensities were investigated in laboratory,respectively.The results showed that S.oryzae adults had the highest phototactic ratio(81.11%)to LED lights with a wavelength of 590 nm and a light intensity of 170 lx.T.castaneum adults had the highest phototactic ratio(92.22%)to LED lights with a wavelength of 520 nm and a light intensity of 120 lx.L.serricorne adults had the highest phototactic ratio(77.78%)to LED lights with a wavelength of 460 nm and a light intensity of 170 lx.C.ferrugineus adults had the highest phototactic ratio(93.33%)to LED lights with a wavelength of 365 nm.T.confusum adults had the highest phototactic ratio(84.44%)to LED lights with a wavelength of 460 nm and a light intensity of 120 lx,and S.zeamais adults showed the highest phototactic ratio(88.89%)to LED lights with a wavelength of 365 nm.These results have reference value for effectively designing integrated pest management(IPM)strategies utilizing the phototaxis of stored grain insects.
