Researchers believe we could use a microscopic fungi to control the actions of insects
While mind control has long been a staple of?science fiction films, many people don't realize that there are organisms capable of just such a feat. The genus of fungi known as?Ophiocordyceps contains several of these parasites, and while they mainly target small ants, scientists believe they could be put to use as tiny biological soldiers to fight against mosquitos that carry?deadly malaria.
When a spore of the fungus Ophiocordyceps camponoti-balzani?lands upon an unsuspecting ant, it begins burrowing deep within its exoskeleton. Once inside, it weakens its victim, and consumes the ants insides in order to grow. When the microscopic organism has reached maturity, it literally takes control of the ant's brain. With its mind in shambles, the ant searches for a hanging leaf and when a suitable spot is found, the insect locks its jaws onto the plant's underside in a death grip. The parasite then finishes off its victim, and breaks free of the bug's now hollow shell, spreading more spores and starting the cycle in motion again.
As gruesome as its methods are, scientists are beginning to learn that?Ophiocordyceps and other similar parasites could be reprogrammed and put to work for human benefit. One such theory posits that if we could tweak a fungi which targets mosquitos, and instead of killing the insects outright ? which could topple an entire ecosystem ? the parasite could make the bugs crave only a certain type of animal or species. Then, over time, mosquitos would no longer hunger for human blood, and malaria-prone areas could breathe a sigh of relief.
However, not everyone is on board with this type of?biological manipulation, and given the inherent nature of playing with traits that have been programmed by?nature, the skepticism is understandable. Unfortunately, the natural habitat of these mind-altering parasites ? which mainly reside in specific rain forests ? is quickly shrinking, and researchers are racing to determine what benefits and risks would be associated with such an ambitious endeavor.
