The field research was conducted for the Evaluation of some treatments in banana scarring beetles, Basilepta sp., Colaspis sp over 35 days in banana cv. Grand Naine (G9) during January 2024 at NARC, Tarahara, Sunsari, Nepal. Leaf and fruit-eating chrysomelid beetles cause significant damage to banana crops in Tarahara, impacting both yield and market value. Five treatments modules comprising Chlorantraniliprole(T1), Thiamethoxam(T2), Dimethoate(T3), Neem oil(T4), Emamectin benzoate(T5), and an untreated control(T6). The research was conducted using a Randomized Complete Block Design with four replicates. Beetle counts and leaf scar were recorded weekly from the top leaves of 24 randomly selected banana plant. The results demonstrated significant differences in the effectiveness of the treatments. Application of Thiamethoxam(0.5ml/lit) or Chlorantraniliprole(0.4ml/lit) in a weakly interval emerged as the most effective, significantly reducing both beetle counts and scarring by day 35. Neem oil showed moderate control, offering a valuable organic alternative with additional benefits for integrated pest management. Dimethoate and Emamectin benzoate were less effective, with limited reduction in beetle populations and scarring. The untreated control maintained high beetle and scarring counts throughout the study period. These findings support the use of these treatments to enhance the health and productivity of banana crops while promoting sustainable agriculture.
