Mosquito control with Bioinsektisida

So far for controlling Aedes aegypti mosquito and Anopheles, there are still many people who use chemicals (insecticide). In fact, it's not environmentally friendly and had no indication of resistance of mosquitoes Aedes aegypti and Anopheles in various places on certain types of insecticides.

"To Aedes aegypti is a tendency organofosfat tolerant of compounds," said Head of Research Center of Disease Vectors and Reservoir, Ministry of Health, Dr MS Damar Tri Boewono in Republika. This is Organofosfat chemicals to control mosquitoes and larva. For this reason, he continued, the Research Center of Disease Vectors Reservoir bioinsektisida efficacy test Bacillus thuringiensis and Bacillus sphaericus against mosquito larvae of malaria vectors and dengue hemorrhagic fever (DHF). "The result was good enough," said Rosin.

Research carried out is an oasis (as much as a cotton buds) from cultured spores of Bacillus thuringiensis inserted into the coconut water. Coconut intact opened slightly. Having entered the spores then closed again. After one week left in the coconut, Bacillus sphaericus and Bacillus thurigiensis is already a lot, obviously the laboratory Damar already recommended by the WHO (World Health Organization) for testing insecticides that will be performed by a program or households.

He further said that if the target of bioinsektisida is the Anopheles mosquito larvae, the spores must be floating. Conversely, if the target Aedes aegypti mosquito larvae spores must then be at the bottom. Now, bioinsektisida is already used by Newmont and Freeport. Thus, Damar said, when bioinsektisida will be used to control the Anopheles larva and Aedes aegypti, the material must be designed as such in accordance with the behavior of the mosquito larva is. He admitted that bioinsektisida is safe, no side effects, and environmentally friendly.

According to him, never existed in the public demonstration to prove the security bioinsektisida. Way, bioinsektisida incorporated into drinking water, then drink. Proved that people who drink do not die, he explained. In another part he says with organofosfat mosquito control can still be, but should increase the dose. Thus the cost is more expensive and resistance will be higher. "If I am telling the truth from the farm, this organofosfat more toxic to the soil," said Rosin.

Once insekstisda material goes into the ground, he will carry the rain water and will be collected in one place. Mosquitoes will breed there and will adapt to the environment so that the resistance will emerge. Both these spores, he explained, was sold in the market. These spores must be stored in a cool place so as not to die.
