Rice is a seed of the grass species Oryza sativa (Asian rice) or Oryza glaberrima (African rice). As a cereal grain, it is the most widely consumed staple food for a large part of the world's human population, especially in Asia. The pooled data indicates that all insecticides were effective over control in reducing the population of coccinellids recorded at 3rd, 7th and 14th days after insecticidal applications. Chloropyrifos was found significantly superior (.65, .50, .77) followed by Cypermethrin (.78, .66, .85), Carboryl (.85, .69, .82), Cartaf (.85, .68, .86), Imidaclorpid (.87, .64, .83), Tiomethoxam (.90, .60, .80), Triazophos (.85, .90, .95) as compared to control (1.18, 1.31, 1.44) at 3rd, 7th and 14th days respectively. Percentage population reduction of coccinellids recorded at 3rd, 7th and 14th days after insecticidal applications. Chloropyrifos found significantly superior (41.31, 59.70, 43.18) followed by Thiomethoxam (30.25, 58.50, 50.33) as compared to other treatments Cartaf (28.78, 49.15, 58.88), Imidachlorpid (29.64, 53.80, 45.14), Carborfuran (29.57, 46.81, 37.28), Carboryl (24.00, 44.93, 40.07) and Triazophos (17.65, 22.18, 29.79) respectively. The data for the efficacy of different treatments were evaluated on the basis of percentage population reduction. All the treatments were effective. The pooled data indicates that all insecticides were effective over control in reducing the population of Spider recorded at 3rd, 7th and 14th days after insecticidal applications. Imidachloprid was found significantly superior (.31, .22, .48) followed by Carboryl (.41, .36, .63) Triazophos (.64, .45. .60), Cartaf (.75, .43, .84) Thiomethoxam (.75, .62, .88), Cypermethrin (.86, .65, .93) and Chloropyrifos (.88, .77, 1.28) as compared to control (1.16 1.37, 1.41) at 3rd, 7th and 14th days respectively.
