    摘要:

    采用校正趋色法在实验室条件下,研究了赤拟谷盗、杂拟谷盗、米象、玉米象、嗜卷书虱、无色书虱6种储粮害虫对黄色和蓝色的趋向性行为反应。研究发现,黄色和蓝色对不同储粮害虫的诱集效果大多存在显著性差异,黄色仅对赤拟谷盗表现出稳定的诱集效果,最高诱集率为19.76%;蓝色在无食源时对杂拟谷盗、玉米象、嗜卷书虱和米象均呈现明显的诱集效果,最高诱集率分别为39.9%、28.6%、24.6%和22.6%;书虱大多呈趋避反应。但食物源的存在对颜色的诱集作用具有明显的干扰效果。在加入食物源背景之后,黄色对赤拟谷盗的诱集率大幅下降,对杂拟谷盗和玉米象的诱集率明显上升;蓝色对赤拟谷盗的诱集效果上升为最强。而杂拟谷盗却由诱集变为趋避。研究表明,黄色和蓝色对储粮害虫的诱集效果会被外界因素干扰,可为利用色彩进行诱捕的设备研发提供思路。

    Abstract:

    The tropism of six kinds of stored grain pests,Tribolium castaneum, T.confusum,Sitophilus oryzae,S.zeamais,Liposcelis bostrychophila, L. decolor to yellow and blue was researched under laboratory condition by color correction. The results showed that there were significant differences among most of the trapping effect of yellow and blue to different pests. The trapping effect of yellow only appeared stable to Tribolium castaneum with the highest trapping rate of 19.76%. The significant trapping effect of blue appeared to T.confusum, S. zeamais, L. bostrychophila and S. oryzae as without food source, with the trapping rates 39.9%, 28.6%, 24.6%, 22.6%, respectively;Liposcelis most showed phobotaxis reaction. Food as a background has obvious interfere on the trapping effect. After adding a food source as a background, the trapping rate of yellow to T. castaneum, T.confusum and S. zeamais increased significantly; the increase of trapping effect of blue to T. castaneum was the top one. While to T.conf usum changed from trapping to elude. The results showed that the trapping effect of yellow and blue to stored grain insects was interfered by extraneous factors, which provided ideas for the research and development of equipment for trapping by color and light waves.
