  Abstract: Abstract The sweet potato weevil ( Cylas formicarius Fab.) is one of the most damaging sweet potato pests. To prevent an economic crop loss, it is very important to develop a suitable and efficient integrated pest management strategy. A field experiment was set up with three replications at Jamalpur to select the best-integrated management package from eight different treatments against sweet potato weevil. The result showed that the lowest percentage of infestation by number (2.94%) and weight (3.22%) was found when the crop was planted on November 01; earthing-up for two times, Carbofuran 5G was sprayed @ 15 kg/ha at 60 days after sowing with irrigation and tuber was harvested at 130 days after planting. The marketable yield (23.75 kg) and percent increase of yield than control (50.86%) performed highest in the same combination. These findings suggested an effective integration of different management strategies to reduce sweet potato weevil infestation in Bangladesh successfully.
