The result &#8211; they made no physical contact with females, even after three days in the same cage.<!-- --><\/p>\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">Female mosquitoes are the ones that spread diseases to people, and so trying to prevent them having babies would help reduce overall numbers. <!-- --><\/p>\n<\/div>\n<div data-component=\"text-block\" class=\"sc-18fde0d6-0 dlWCEZ\">\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">The team from the University of California, Irvine studied Aedes aegypti mosquitoes, which spread viruses to around 400 million people a year. <!-- --><\/p>\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">They closely observed the insects&#8217; aerial mating habits &#8211; that can last between a few seconds to just under a minute &#8211; and then figured out how to disrupt it using genetics. <!-- --><\/p>\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">They targeted a protein called trpVa that appears to be essential for hearing.<!-- --><\/p>\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">In the mutated mosquitoes, neurons normally involved in detecting sound showed no response to the flight tones or wingbeats of potential mates. <!-- --><\/p>\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">The alluring noise fell on deaf ears.<!-- --><\/p>\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">In contrast, wild (non-mutant) males were quick to copulate, multiple times, and fertilised nearly all the females in their cage.<!-- --><\/p>\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">The researchers from the University of California, Santa Barbara, who have <!-- --><a target=\"_blank\" href=\"https:\/\/www.pnas.org\/cgi\/doi\/10.1073\/pnas.2404324121\" class=\"sc-c9299ecf-0 bZUiKB\" rel=\"noopener\">published their work in the journal PNAS<!-- --><\/a>, said the effect of the gene knock-out was &#8220;absolute&#8221;, as mating by deaf males was entirely eliminated.<!-- --><\/p>\n<\/div>\n<div data-component=\"text-block\" class=\"sc-18fde0d6-0 dlWCEZ\">\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">Dr Joerg Albert, from the University of Oldenburg in Germany, is an expert on mosquito mating and I asked him what he made of the research.<!-- --><\/p>\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">He said attacking sense of sound was a promising route for mosquito control, but it needed to be studied and managed. <!-- --><\/p>\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">&#8220;The study provides a first direct molecular test, which suggests that hearing is indeed not only important for mosquito reproduction but essential. <!-- --><\/p>\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">&#8220;Without the ability of males to hear &#8211; and acoustically chase &#8211; female mosquitoes might become extinct.&#8221;<!-- --><\/p>\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">Another method being explored is releasing sterile males in areas where there are pockets of mosquito-spread diseases, he added. <!-- --><\/p>\n<p class=\"sc-eb7bd5f6-0 fYAfXe\">Although mosquitoes can carry diseases, they are an important part of the food chain &#8211; as nourishment for fish, birds, bats and frogs, for example &#8211; and some are important pollinators. <!-- --><\/p>\n<\/div>\n<\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/www.bbc.com\/news\/articles\/c207gvrn65do\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Getty Images Scientists believe they have found a quirky way to fight mosquito-spread diseases such as dengue, yellow fever and Zika &#8211;
