Biology and Management of Cotton Grey Weevil: A Review

Cotton grey weevil is becoming a primary pest of agricultural and horticultural crops all over the world including Pakistan. The various management strategies such as chemical, biological and cultural have been adopted against this pest throughout the globe. The previous published literature was reviewed with the aim to evaluate the best strategy among all strategies to control the pest. Male is shorter as compared female with approximately 6.0 to 8.5 mm length. Adult feed on the leaves and cause huge crop losses. The current reviewed literature concluded that chemical control can give quick control of adult due to their fly ability while control of pupae, larvae and eggs is difficult due to their location in or on the soil. The excessive use of chemicals to control pest can caused mortality of other biological fauna. To avoid the excessive application of chemicals, biological and botanical control should be promoted and applied that will prove best option against the current pest.
