ABSTRACT: The study investigated the insect pest management practices of summer vegetables and profitability of the practices in Sirajgonj district of Bangladesh through survey among the growers. In total fifteen groups of insect under 7 orders attacked 5 vegetable crops in the study area. Among the status groups, a total of 9 were found as major and 6 as minor groups. Chemical control, physical and hand picking, integrated pest management (IPM), field cleaning, botanical pesticide, biological control, twig or leaf cutting, crop rotation, mulching and intercropping methods were practiced to manage insect pests. Farmers apply tactics dealing with other farmers, agricultural dealers, agricultural extension officers or obtaining ideas from agricultural fair and demonstration also with their experience. The findings showed that the highest total return was obtained from the bitter gourd (532170 Taka/ha) and lowest in okra (374250 Taka/ha). Variable and total cost bases benefit cost ratios (BCR) were the highest in brinjal (2.7 and 2.4, respectively) and the lowest in okra (2.5 and 2.1, respectively). Among five vegetable crops, brinjal was more profitable in terms of gross margin, net return and benefit cost ratio compared to other summer vegetables.
