Question

The European red mite has been found in several early apple samples. You want to use an insecticide, but youre not sure which one to select. Insecticide 1 is known to kill all insects with one or two sprayings, but it takes a bit long to break down. Insecticide 2 breaks down to harmless components very quickly, but is more effective on arachnids than Insecticide 1. You want to kill mites, but not the predatory spiders that inhabit virtually every outdoor arena. Which insecticide would you use? Justify your reasoning.

Answer 1

1 because insecticide 2 breaks down harmless components and you only want to kill a certain insect, if you chose 2 then it would kill the harmless spiders.
