A researcher sprays a new pesticide on thousands of insects of the same species that live in a large field a few of the insect survive what can be concluded by the researcher?

The researcher can conclude that a small percentage of the insects possess traits that confer resistance to the new pesticide. This could indicate a genetic variation within the population that allows some individuals to survive despite the pesticide application. Further investigation would be necessary to understand the mechanisms of resistance and the implications for future pesticide use.
