I would like to say a few words about mosquitoes. They are very nasty insects. They parasites on all living beings: people, animals. In Russia, mosquitoes are relatively harmless, although there is a huge number of them in Russia. But, in southern countries, in the tropics, mosquitoes are very dangerous. Their bite can kill a person. Theу are malarial mosquitoes...  The disease that they carry is called malaria. The mosquitoes breed on a warm time..

В России комары относительно безобидны, хотя их огромное количество в России. Но, в южных странах, в тропиках, комары очень опасны. Их укус может убить человека. Это малярийные комары.. болезни, которые они переносят называется малярией. Комары размножаются в теплое время...

People often used horses as means of transportation, and  , for example, the sheep give us   wool which we so need.

About the question "Could animals be used as secret agent?", I think it's impossible. Animals can't be used as  secret agent, because the exchange of information is impossible.
