The European red mite has been found in several early apple samples.  You want to use an insecticide, but you're 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.

 

The European red mite is a new introduced pest. It brings damage to nuts, pome, stone fruits, and even with berries. It destroys leaves and force the fruits to russet. If I want to eliminate them, I'll use the insecticide 2 which breaks down to harmless components in a short period of time. This insecticide will help the deterioration of mites in a safe and careful way. It is manifested in an instant, which makes it more reliable than the other insecticide. It is said that it's more effective on arachnids, therefore, it will also have the same effects on mites. Why? Because mites and arachnids are related, distantly. They both belong to the same class. Additionally, you don't want to harm other insects while eliminating these mites. Given that supplementary fact, insecticide 2 is a better choice rather than insecticide 1.
