Abstract

The application of insecticides in rice ecosystems not only significantly reduces the population of pest insects but also affects the populations of predatory arthropods, parasitoids, and neutral insects. Therefore, an alternative that is safer for the environment, non-target organisms, and humans is necessary. One such alternative is the use of biological agents, such as the entomopathogenic bacterium Bacillus thuringiensis. The aim of this study was to suppress pest populations in rice plants as well as preserve populations of predatory arthropods and natural enemies. The research was conducted in Muara Enim Regency from July to October 2023. Observations of arthropod diversity and roles in rice fields were carried out using pitfall traps, insect nets, and visual surveys. Agronomic characteristics observed included plant height, number of tillers, and yield. The study used a Randomized Complete Block Design (RCBD) with three treatments: bioinsecticide B. thuringiensis enriched with biourine, synthetic insecticide with active ingredient abamectin, and a control, each repeated five times every two weeks. The results showed that the Shannon-Wiener diversity index (H') for the application of B. thuringiensis enriched with biourine was 3.31, for the synthetic insecticide was 2.51, and for the control was 3.11. The application of B. thuringiensis enriched with biourine influenced plant height, number of tillers, and crop yield. Based on observations using pitfall traps and insect nets, the highest number of species was found in the orders Coleoptera and Hemiptera.
