ABSTRACT: The study was conducted in four districts viz., Rajshahi, Noagaon, Chapainawabganj and Natore under Barind areas of Bangladesh during July to November 2020 through pre-tested questionnaire survey among the target farmers, i.e. 30 farmers per district to gather information on existing socio-economic aspects of T. Aman rice farmers as well as their opinion on insect pests and insecticide application against insect pest. Most of the farmers were middle to old aged with illiterate to primary level of education having small to medium farm size, small to medium family size with high farming experiences and medium to high level of annual income. According to the farmers’ opinion in selected areas, stem borer (Scirpophaga incertulas), leaf folder (Cnaphalocrosis medinalis) and brown plant hopper (BPH) (Nilparvata lugens) were detected as severe while ear cutting caterpillar (Mythimna separata) and rice gall midge (Orseolia oryzae) were the major insect pests of T. Aman rice. For combating those insect pests’, farmers mainly use Thiamethoxam (20%) + Chlorantraniliprole (20%), Chlorpyrifos (20%), Chlorpyrifos (50%) + Cypermethrin (5%), Acephate (45%) + Imidacloprid (25%), Cartap (50%) and Carbofuran (3% or 5%). Number of insecticides use, number of sprays and number of insects pests manage by farmers were positively correlated with the education level, farm size, farming experience and annual income of the respondents.
