Question

which factor is least likely to lead to the development of pesticide resistance in pests? surviving pests passing on resistant genes use of the same pesticide repeatedly low genetic variation in the pest population frequent pesticide application

Explanation:

To determine the factor least likely to lead to pesticide resistance, we analyze each option:

• "Surviving pests passing on resistant genes" contributes to resistance as resistant genes spread.
• "Use of the same pesticide repeatedly" selects for resistant pests over time.
• "Low genetic variation in the pest population" means there are fewer genetic differences, so there's less chance for resistance - causing mutations or variations to exist. With low variation, the population has limited genetic material to develop resistance.
• "Frequent pesticide application" exerts strong selection pressure for resistance.

So, low genetic variation in the pest population is least likely to promote resistance development.

Answer:

low genetic variation in the pest population
