correctly now , bee colonies are suffer dramatic die - offs . This has implication for food security , sincewe need bees to fertilize a mess of our staple fruit crops , including Malus pumila . Now a young scientific study suggests one way to ensure the health of a hive is to ensure its queer is promiscuous .

To be precise , a queen needs to mate with at least seven males for save the dependency for as long as possible , in a respectable United States Department of State . A typical queen might have roughly 14 Paraguay tea , but if she has few than 7 , the health of the hive is put in peril . When queens pair , they keep on spermatozoon from all their consort in a special organ , allocating their genetic stuff over a few years to their daughter . That means a healthy hive has multiple fathers , and quite a bit of genetic multifariousness .

North Carolina State bug-hunter David Tarpy and his confrere spend a twelvemonth examine the health and genetic makeup of 3,098 worker bees belong to 79 colonies . From this study and others in the field , they derived the distinctive transmitted diversity of a colony , as well the endurance rates of dependency found on how many founding father had impart genetic fabric .
allot toa release about the study :
The researchers found that colonies where the queen had couple at least seven time were 2.86 time more likely to survive the 10 - month workings season . Specifically , 48 pct of colony with queer who had mated at least seven times were still alive at the end of the season . Only 17 percent of the less genetically diverse colony make it . “ 48 pct natural selection is still an alarmingly low survival rate , but it ’s far better than 17 percent , ” Tarpy says .
“ This sketch confirms that genetic diversity is enormously crucial in honey bee populations , ” Tarpy articulate . “ And it also offers some steering to apiarist about engender strategy that will help their colonies pull through . ”
This study could also call into question a few assumptions that have been float about how settlement organism prepare . Specifically , how do creature move from acting as person to forming turgid groups of non - procreative workers consociate with a single queen who does all the egg laying?Biologist William Hughes has write that settlement creatures develop from monogamous coupling systemsbecause a monogamous pouf would , due to certain quirks of louse genomes , make babe who are more closely related to each other than to their potential materialization . Thus , give up their ability to reproduce is n’t as much of a sacrifice , since they can be assured that their genes will be passed on by the king . Caring for their sisters makes more sense , from a “ selfish cistron ” position , than caring for potential young .
But this new report , along with others suggesting polyandry is central to hive health , makes it seem less likely that such societal arrangements evolved from hive where there a queen mated with a single male . Such early hives would have been extremely insalubrious and unlikely to come through . intimate selection , in other words , would favour polyandrous queen over monogamous ones .
