JLSO 6(1):95-105. Crickets (Gryllus bimaculatus) are an important pests on rice that can reduce productivity. The application of Bacillus thuringiensis bioinsecticide is expected to be an alternative methode to control these pest. The objective of the study was to investigate optimal dose of B. thuringiensis in suppressing rice damage was caused by G. bimaculatus. The observation were conducted on rice cultivation in Pelabuhan Dalam Village, Pemulutan Subdistrict of Ogan Ilir Regency.
