What does cross-resistance refer to in the context of pesticide resistance?

A formulation with the active ingredient enclosed in capsules of polyvinyl
A pest population that is already resistant to one pesticide becomes resistant to a related chemical
Organisms whose population has been reduced to near extinction
All the features that surround and affect an organism

The correct answer is: A pest population that is already resistant to one pesticide becomes resistant to a related chemical

Cross-resistance in the context of pesticide resistance refers to a scenario where a pest population that is already resistant to one pesticide becomes resistant to a related chemical. This phenomenon occurs because pests that have developed resistance mechanisms to one pesticide may also exhibit the same resistance to other chemicals that have a similar mode of action or chemical structure. This is an important consideration when developing pest management strategies to combat resistance effectively. Option A, which mentions a formulation with the active ingredient enclosed in capsules of polyvinyl, is not related to the concept of cross-resistance in pesticide resistance. Option C, describing organisms whose population has been reduced to near extinction, does not align with the definition of cross-resistance. Option D, referring to all the features that surround and affect an organism, is a broad definition not specific to the concept of cross-resistance in pesticide resistance.
