Vedclass · Answer

(D) Pests develop resistance to insecticides through various physiological and biochemical mechanisms. $1$. Less permeable cuticles: This reduces the rate of absorption of the insecticide into the pest's body. $2$. Faster storage of toxin in fat: This sequesters the toxin away from the target site,preventing immediate harm. $3$. Enzymes for metabolising toxin: Many resistant pests possess specific enzymes (like cytochrome $P450$ monooxygenases) that break down the insecticide into non-toxic metabolites. Since all these mechanisms contribute to insecticide resistance,the correct answer is $D$.
