ABSTRACT

There are numerous factors that cause reduction in cotton yield and quality, insect attack is one of the major limiting factors for optimum cotton production. Among cotton pest whitefly, jassid and thrips are more important in sucking pests while pink bollworm is very destructive among bollworms. Therefore, the present study was planned to work out the behavior of different cotton cultivars i.e., MNH-1086, WEAL-AG-10, SLH-CHANDI, FH-494, MNH-1050, FH-492, WEAL-AG-9, BH-224, VH-418, SLH-Afnan-II, WEAL-AL-AG-CKC3-01, FH-142, FH-414, RH-KING 20, WEAL-AG-20 1(ii), FH-ANMOL, SLH-55, BH-225, UAM-20, FH-498, and WEAL-AG-11 for insect pest infestation and cotton yield as well as its impact on fiber quality. The cultivars differed in their susceptibility to sucking insects and pink bollworm. The lowest whitefly population was observed on genotypes FH-492 (2.48), FH-498 (2.97), and ‘FH-494 (2.80) per leaf. The lowest jassid population was recorded on cultivars FH-494 (0.87), FH-498 (0.97), and FH-492 (0.68) per leaf. The lowest thrips infestation was recorded on FH-492, FH-494 and FH-498, having 1.05, 1.13, 1.20 per leaf, respectively. The cultivar FH-492 (0.20) had the lowest number of pink bollworms in left over bolls. The maximum number of bolls per plant was recorded for FH-492 (76.33) and the highest yield was observed in FH-492 (3052.95 Kg/ha). FH-492 has shown remarkable lenience of morphological and entomological features, and resistance to insect pests and CLCuD. The demands of farmers, laborers who harvest crops, and other investors including those in the cotton industry may be met by the introduction of this variety. The present study signifies for recommended as the most suitable commercial cotton cultivars for agro-climatic conditions of Faisalabad.
