Rice leaffolder has become a serious pest in the last two decades. It causes up to 50 to 70 percent leaf damage and consequently up to 46 percent yield losses in case of severe infestation. A field experiment was conducted at Rice Research Institute, Kala Shah Kaku Punjab Pakistan in which population incidence of rice leaffolder and efficacy of different insecticides evaluated. Population observed form end August to termination of Kharif season. Highest population of rice leaffolder was recorded in September and October. Insecticides, proved, viz., Karate 2.5EC (Lambda cyhalothrin) @ 160ml 86.65%, Pravo 10EC (fipronil +lambda cyhalothrin) @ 300 ml 85.25%, Hoopoe 4G (cartap hydrochloride) @ 9 kg 85.85, Oncol 3G (Benfuracarb) @8 Kg 89.53%, Mover Plus 4.3G (cartap hydrochloride) @ 4.5 Kg 82.77%, Star 4G (cartap hydrochloride) @ 9 kg 78.40%, Padan 4G(cartap hydrochloride) @ 9 kg 86.83%, Virtako 0.6G (thiamethoxam + chlorantraniliprole) @ 4 kg 72.05%, Ferterra 0.4G (Chlorantraniliprole) @ 4 kg 91.21%, Paidan 8G (Cartap hydrochloride) 8 kg 84.18% effective. Insecticide treatedplots yielded higher than the control. Highest 3.62 t/ha was recorded with Hoopoe 4G and lowest with Star 4G 2.99 t/ha as compared to 1.95 t/ha of control. All treatments were statistically at par with each other but significantly different from control. In case of yield benefits, 34.78 percent to 46.27 percent increase was recorded. All the treatments were proved statistically at par against beneficial fauna.
