The effects of sucking insect-pests on the morpho-physiological and biochemical changes in the leaves of four cotton genotypes-Bio 100 BG-II and GCH-3 (highly tolerant); KDCHH-9810 BG-II and HS-6 (highly susceptible)-were examined. Compared to tolerant genotypes, susceptible genotypes showed a decrease in relative water content, specific leaf weight, leaf area, photosynthetic rate, and total chlorophyll content, with an increase in electrolyte leakage. Hydrogen peroxide and total soluble sugar content were higher in susceptible plants. In contrast, resistant plants had higher levels of total soluble protein, total phenolic content, gossypol content, tannin content, peroxidase activity, and polyphenol oxidase. The findings demonstrated that the Bio 100 BG-II and GCH-3 genotypes effectively offset the impact of sucking insect-pests by modifying the factors mentioned above. The KDCHH-9810 BG-II and HS-6 genotypes could not completely negate the effects of sucking insect-pests. Customized metabolites and total soluble protein are more efficient in protecting cotton plants from damage brought on by infestations of sucking insects and pests.

研究了吸食性害虫对四种棉花基因型（Bio 100 BG-II和GCH-3，高耐受性；KDCHH-9810 BG-II和HS-6，高敏感性）叶片形态生理和生化变化的影响。与耐受性基因型相比，敏感性基因型的相对含水量、比叶重、叶面积、光合速率和总叶绿素含量降低，电解质渗漏增加。敏感性植株中的过氧化氢和总可溶性糖含量较高。相比之下，抗性植株的总可溶性蛋白、总酚含量、棉酚含量、单宁含量、过氧化物酶活性和多酚氧化酶水平较高。研究结果表明，Bio 100 BG-II和GCH-3基因型通过改变上述因素有效抵消了吸食性害虫的影响。KDCHH-9810 BG-II和HS-6基因型不能完全消除吸食性害虫的影响。定制的代谢产物和总可溶性蛋白在保护棉花植株免受吸食性昆虫和害虫侵害方面更有效。
