Cotton Mealybug, Phenacoccus solenopsis Tinsley

Mealybug, Phenacoccus solenopsis Tinsley, is emerging as a key insect pest on Bt cotton since 2005. White waxy build-up on terminals, stems and branches of infested plants accompanied by intense activity of ants is a sure sign of mealybug attack. The bugs suck sap from plants leading to stunted growth and drying. Black moulds grow on the honeydew secretions of the mealy bug. Its natural spread by wind, water, ants, intercultural operations and other human activities like movement of infested material contributed to its quick colonization of new areas. High temperatures along with low humidity are congenial for its rapid growth and multiplication, while high intensity rains and wet spells adversely affect its infestation.
