Mosquito-borne diseases kill approximately 725,000 people a year. But scientists are cracking down on these pests with some high-tech tools.
每年大約有725,000人死于蚊子傳播的疾病。但科學(xué)家正在用一些高科技工具來對(duì)付這些害蟲。
One group of inventors created a mosquito-killing laser. The device can detect insects in its view and choose which ones to shoot down.
一組發(fā)明家發(fā)明了一種滅蚊激光。該裝置可以在其視圖中探測(cè)昆蟲，并選擇將哪些擊落。
Another firm created mutant mosquitoes. Scientists genetically modified males with faulty genes that cause their offspring to die soon after birth. And it's already had some success: Field studies showed this caused an 82 percent decline in mosquito populations.
另一家公司制造變異蚊子。科學(xué)家對(duì)有缺陷基因的雄性進(jìn)行基因改造，使它們的后代出生后不久就死亡。而且已經(jīng)取得一些成功，現(xiàn)場(chǎng)研究發(fā)現(xiàn)這使得蚊子種群下降了82%
Researchers have also proposed infecting mosquitoes with fungus, since mosquitoes have developed resistances to lots of insecticides.
研究人員還建議用真菌感染蚊子，因?yàn)槲米訉?duì)許多殺蟲劑產(chǎn)生了抗性。
One group of scientists took a strain of mosquito-killing fungi and combined it with toxins from spiders and scorpions to make it work more quickly. After five days, nearly none of the mosquitoes infected with the fungus could transfer malaria.
一組科學(xué)家采集了一株消滅蚊子的真菌，并將其與蜘蛛和蝎子的毒素結(jié)合起來，使之更迅速的發(fā)揮作用。五天之后，感染真菌的蚊子幾乎都不能傳播瘧疾。
