Rice (Oryza sativa L.) is a major carbohydrate source for a significant portion of the global 
population, including Indonesia, where nearly 95% of the population consumes rice as a staple 
food. The demand for rice continues to rise with the increasing population. One of the major 
challenges in rice cultivation is pest infestation, particularly the rice bug (Leptocorisa acuta), 
which can cause substantial damage to crops. This study aimed to evaluate the effect of 
different doses of the biological agent Beauveria bassiana in controlling the rice bug 
population in rice plants. The research was conducted at the UPT Plant Protection and 
Horticulture Mojokerto, from January to December 2023. A Completely Randomized Design 
(CRD) was used, with four treatment groups of Beauveria bassiana concentrations: P0 (no 
treatment), P1 (9 ml/L), P2 (12 ml/L), and P3 (15 ml/L), each repeated four times, resulting in 
16 experimental units. The results showed that the application of Beauveria bassiana
effectively reduced the rice bug population. Mortality started at 5 days after application (DAA) 
for P2 and P3, while mortality for P1 occurred at 6 DAA. The fastest mortality was observed 
in P3 (15 ml/L), followed by P2 (12 ml/L), and P1 (9 ml/L), while no mortality was observed 
in P0. Infected rice bugs showed signs of mummification, with their bodies hardening and 
being covered with white fungal mycelium. Based on the findings, the optimal dose for 
controlling rice bugs was 15 ml/L. Further field studies are recommended to assess the 
effectiveness of Beauveria bassiana in controlling pest populations under varying 
environmental conditions.
