中文摘要:

为探明红火蚁Solenopsis invicta工蚁对颜色信号的选择与利用，本研究测定了不同颜色色卡对工蚁的趋向行为以及不同颜色饵料对工蚁觅食行为的影响，以期为红火蚁的高效监测与防控提供重要基础。结果表明颜色显著影响了红火蚁工蚁的趋向行为，黑色对工蚁的引诱率最高，可达32%；黄色对工蚁的引诱率最低，仅为7%。研究也发现不同颜色的饵料显著影响了红火蚁工蚁的觅食。在5 min时间内，工蚁在黄色、绿色以及蓝色饵料上觅食的数量最多，显著高于在紫色和黑色上饵料的觅食工蚁数；工蚁对红色、橙色、黄色、绿色、蓝色饵料的搬运量最大，显著高于紫色与黑色的饵料。综上，红火蚁工蚁可以识别与利用颜色信号，在制备红火蚁监测与防控饵剂时，可以考虑将饵剂染色红、橙、黄、绿、蓝等反射波长较长的颜色，以便工蚁能快速定位到饵剂并搬运更多的饵剂到蚁巢中。

英文摘要:

To explore the selective behavior and utilization of Solenopsis invicta workers to chromatic cues, the effect of different color cards on the tendency behavior and different color baits on the foraging behavior of worker ants were examined to provide an important basis for the effective monitoring and control of S. invicta. The results showed that color significantly affected the tendency behavior of S. invicta workers. The black card had the highest attraction rate to the workers, which was up to 32%. The yellow card showed the lowest attraction rate, which was 7%. The results also indicated that different color baits obviously influenced the foraging behavior of workers. Within 5 min, more worker ants foraged on the yellow, green and blue baits, which was significantly more than that on purple and black baits. The weight of red, orange, yellow, green and blue baits transported by the worker ants was obviously more than that of purple and black baits. In conclusion, S. invicta workers can discriminate and utilize the chromatic cues. In the preparation of monitoring and control baits, the baits can be dyed with the color had long reflective wavelength such as red, orange, yellow, green and blue, so that the workers can quickly locate the baits and transport more baits to their nests.
