The mealybug Phenacoccus gossypiphilous (Stanley) played havoc with the cotton crop in Pakistan during 2005. To control this pest, insecticides of different groups were evaluated in both the laboratory and in field conditions. In the laboratory, bifenthrin, profenofos and chlorpyrifos proved to be the best insecticides for mealybug control, based on their susceptibility with the leaf dip method for their LC₅₀. In field conditions, the recommended application rates of methomyl, profenofos and chlorpyrifos provided the best control: the lethal time studies proved their efficiency for better and timely control of this sporadic pest. The present study has shown that the insecticides tested, in particular profenofos, chlorpyrifos, methomyl and bifenthrin, provide satisfactory control of the cotton mealybug. The control of the insect pest complex throughout the cotton crop predominantly depends on wise and justified use of these chemicals, and necessitates development of an integrated pest management strategy.
