The studies on varietal resistance of cotton crop against mealybug were conducted at Experimental Field, Entomology Section, ARI, Tandojam from May to November 2007. Fifteen varieties of cotton crop viz. Cris-134, Chandi, FH-901, CIM-473, CIM-499, Shahbaz, TH-57/96, NIAB-111, CIM-496, Haridost, Okra leaf, Sindh-1, NIAB-78, Bt. and Okra desi were cultivated in a Complete Randomized Block Design with 4 replications. Results indicated that this was a new mealybug species in Pakistan known as Phenacoccus solenopsis Tinsley, which appeared on cotton crop two months after sowing and remained till harvest of the crop. Data indicated that there were two population peaks of the mealybug. The analysis of variance showed a highly significant (P less than 0.001) difference in the population of mealybug on 15 varieties.
