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.
