A monumental and ongoing important scientific battle is the controlling of mosquito populations that cause premature deaths, and wrought pestilence in all corners of this planet, can now become a significant scientific victory. A natural predator against mosquito larvae is the arthropod, Copepoida. Because of their overwhelming numbers, the use of the Cyclopoida species was examined as they are wholly or primarily free-living, and found throughout all the natural waterways on Earth. This microscopic predator has shown: they can reduce the amount of mosquito larvae in its infested habitat, more effectively then that of the Gambusia affinis, either alone or in a combination. Direct observation has shown that the copepod generally eats detritus material but prefer to eat the bellies out of the larvae instead. The use of two types of mosquito larvae (Anopheles and Culex spp.) has shown whether or not the copepod and/or Gambusia prefer one species of mosquito larvae to the other. The mosquito fish was used for comparison as past research has shown that it is significant at reducing mosquito larvae. Resulting laboratorial research and recorded data has shown there is conclusive scientific proof that these copepods alone can significantly and naturally reduce the amount of mosquito larvae, over that of the Gambusia.
