abstract
Present paper deals with incidence of Uzi fly in different seasons of West Bengal under laboratory condition during silkworm rearing. The result clearly indicates that Uzi infestation in West Bengal is more in rainy season followed by summer. But in winter season infestation is almost negligible. Present investigation also suggests that control rearing where all precautionary measures are taken in a rearing room to prevent the entry of Uzi fly is more beneficial than experimental batch where no precautionary measures are indicated to prevent Uzi fly. Present experiment also reveals that infestation of Uzi fly varied due to different position of rearing trays and infestation of Uzi fly was more in the upper part of the rack.
