Abstract

The stability of the rice field ecosystem is not only determined by the diversity of community structures but also by the characteristics and interactions of the components. This study aims to determine the diversity of insects pests and its natural enemies in the rice field ecosystem in Marannu village, Mattirobulu district, Pinrang regency, South Sulawesi Province, from July to October 2020. The types of pematang plants were treated, namely cucumbers (Cucumis sativus), corn (Zea mays), long beans (Vigna unguicula) and zinnia flowers (Zinnia elegans). Sampling using a insect net and a pitt-fall trap is then put into a plastic tick and identified.
The results showed that there were three parasitoid species from the same order and ten predatory species from six different orders. The dominant parasitoid species was Trichogramma sp., While the largest predator was Lasius niger. In addition, 18 species of pests from six orders were found.
