All of the above

Vedclass · Answer

(D) Insects develop resistance to insecticides through various physiological and biochemical mechanisms. $1$. $Less$ $permeable$ $cuticle$: The insect cuticle acts as a barrier, and modifications that reduce its permeability prevent the insecticide from entering the body. $2$. $Ability$ $to$ $store$ $toxins$ $in$ $fat$: Some insects can sequester toxins in their adipose tissues, preventing them from reaching vital organs. $3$. $Enzymes$ $for$ $metabolism$ $of$ $toxins$: Insects often evolve or upregulate specific enzymes (like cytochrome $P450$ monooxygenases) that detoxify or break down the insecticide before it can cause harm. Since all these mechanisms contribute to resistance, the correct answer is $D$.
