ABSTRACT
Gossypium hirsutum L. is referred as the “king of fiber”, “white gold” cash crop with prominent economic value. This study aims to seek out and examine the potential resistance against infestation of sucking and bollworm insect pests on promising transgenic and non-transgenic cotton genotypes in farmer’s field condition, Naushahro Feroze. The seeds of three popularly grown genetically hybrid cotton varieties namely; KMG-1, KMG-2, KMG-3, and non-Bt NIAB-78 were sown on 8th May 2023. After 6th week of cotton sowing, the data of pest infestation were gathered through randomized complete block design on a weekly interval basis on recommended cotton cultivars. The maximum infestation of the thrips population per leaf was recorded on KMG-3, 1.66, followed by KMG-2, 1.35, KMG-1, 1.12, and 1.01 on NIAB-78. The population of spotted bollworms at 1.63, 0.96, 0.89, and 0.84 were counted. Jassid infestation was recorded at 1.24, 1.02, 0.96, 0.93, and whitefly population fluctuations at 1.18, 0.95, 0.83, and 0.79. Overall maximum pest infestation of thrips was recorded at 1.29 compared to spotted bollworms at 1.08, jassid 1.04, and whitefly 0.94, respectively. Present studies are planned to carry out and collect data for the information of the farming community and to fill the scientific information gap on these cotton genotypes in Sindh, Pakistan. Cotton growers immediately take some control measures before to avoid pest infestation. This study also have significant implications for pest management against destructive insect pest species of the cotton crop in future endeavors.
