<p>Scientists hope to turn the tables on bedbugs after unravelling their genetic make-up.</p>
<p>The bloodsucking insects have recently undergone a major resurgence around the world, with some experts fearing a bedbug pandemic.</p>
<p>In parts of the UK infestations have tripled in the last decade, according to local authority figures.</p>
<p>Now experts in the US hope the first detailed genetic study of bedbugs will reveal chinks in their armour and lead to new methods of pest control.</p>
<p>Study author Dr Omprakash Mittapalli, from Ohio State University, said: &#8220;While bedbugs are poised to become one of the major household pests across the United States in the coming years, we know very little about their genetic make-up and their mechanisms of resistance to insecticides.</p>
<p>&#8220;This is the first study to elucidate the genetic make-up of the insect and obtain fundamental molecular knowledge regarding potential defence pathways and genes that may be involved in metabolic resistance to commonly used pesticides.&#8221;</p>
<p>International travel, the exchange of used furniture and a shift away from powerful but dangerous insecticides such as DDT have all contributed to the rise of the bedbug.</p>
<p>In addition, bedbug populations have developed strong resistance to currently used pesticides such as pyrethroids.</p>
<p>The scientists analysed the DNA of both laboratory-reared bedbugs susceptible to pesticides and &#8220;wild&#8221; bedbugs collected from an apartment in Columbus, Ohio.</p>
<p>They identified two genes that may play a role in pesticide resistance. The research is published in the online journal Public Library of Science ONE.</p>
