There were 12 ant species be found to remove seed of Codariocalyx motorius in Xishuangbanna and Simao districts of Yunnan Province of China. Scientific and effective monitoring to these ant population dynamics is of important significance in analyses the mutuality between the ants and seed disperse of C. motorius. In the study, pitfall trapping method was used to compare attractive efficiency of 4 baits(candy, fish, meat and seed of C. motorius)and 2 no bait controls (water and 3% formaldehyde + water) to the ants. The results showed that the differences in preference and reaction of the ants to different baits were significant. The species and number of ants collected with candy, fish and meat are obviously more than seed of C. motoriu, water and water+3% formaldehyd. Pheidologeton affinis did prefer candy and fish to the rest baits, and consequently the collection of other ants and their numbers was impacted, and however it played little role in dispersing of the seed of C. motorius. A common bail of 3% formaldehyde water did not affect collecting other ants but P. affinis, and could prevent them from decay. Pheidole yeensis, plays a major role in removing the seed, had the same preference to candy, fish and meat, and also a little favorite to the seed. Ants were lazy in looking for food in rainy day, and left their nests to act only when foods were given as an alluring. Our experiment indicated that the baits of candy, fish and meat were not suitable method to estimate real population and species number of ants, but 3% formaldehyde water was a exciting bait for collecting ants, however, it should not be carried out in raining days.
