The male japanese beetle detects and destroys the female pheromone molecule. what tells the male protein to destroy the female pheromone molecule?

The correct answer will be- coded instructions from the genetic material (DNA).

Explanation:

The interaction between the male and female beetles during the reproductive phase of the life cycle is mediated by the production of pheromone chemicals.  These chemicals like other chemicals are coded by the instructions in the DNA.

In the case of Japanese beetles, male pheromone destroys the female hormone which is a part of the survival mechanism. Since it is beneficial for the survival, therefore, evolution has imprinted this behavior in the genes of these beetles.

Thus, coded instructions from the genetic material (DNA) is the correct answer.
