[交流] 【Share】A Possible Safe New Way to Kill Mosquitoes That Spread Malaria

Israeli researchers say they have developed a substance that attracts and kills mosquitoes infected with the malaria parasite. However, the sweet smelling substance is said to be harmless to people and animals.
Scientists at Hebrew University in Jerusalem developed the sugary bait by combining fruit juice oils and boric acid. The fruit juice gets the attention of the mosquitoes. Boric acid kills the insects when they eat it.
The scientists took the boric acid sweet bait to the West African nation of Mali. They sprayed it on plants near man-made ponds. Villagers use water from the ponds during the dry season. But the area is also home to Anopheles gambiae, the mosquito that carries the most deadly form of malaria.
The researchers also placed a sweet-smelling spray on grasses near other ponds. But that spray contained no boric acid.
Both substances also contained a substance that would mark any mosquito that came in contact with it. This way the scientists could count the mosquitoes that fed on the bait.
Yosef Schlein is an expert on insects that affect human health. Professor Schlein led the sweet bait research. He says thirty-eight days of results show the sweet boric acid bait proved very effective at killing mosquitoes.
YOSEF SCHLEIN:" In Mali, we got down by some eighty percent, the females, and ninety percent of the males. But the area is full of little ponds in there, so it is impossible to stop mosquitoes from flying from an untreated pond to a treated pond."
