摘要：Ants have a positive impact on agricultural land as predator on thrips. This study aims to evaluate the association between thrips and ants on chili and watermelon plantations which were conducted in the Maros Regency, South Sulawesi. Samplings of the thrips from the chili and watermelon plants were carried out by using a plastic lid that was placed under the plants, which were then patted by hand until the thrips fall onto the plastic lid and was then counted. The ants were captured using pitfall traps. The results showed that there were two types of thrips, namely Thrips parvispinus and Thrips palmi. The population with the highest average number of thrips was found on farmers' land averaging at 20.4 thrips, with T. parvispinus averaging at 6.4 thrips/observation and T. plami at 14 thrips/observation. Meanwhile, the lowest average population was found on watermelon plants with only 10.3 thrips/observation with T. parvispinus at 1.1 thrips/observation plus T. plami at 9.2 thrips/observation. The highest ant population was found on chili plants combined with watermelons ie 373.3 ants/observation, while the lowest ant population were found on chili plants on farmers' land averaging around 104.3 ants/observation. Based on the data, it can be concluded that the ants play a role in reducing the population of thrips.
