We ’ve distrust for quite some time now that cutting - bound insect powder were responsible for for the ruinous beehive crashes that are inflicting honey bee populations . But recent evidence hint that this may not be the case — instead , Colony Collapse Disorder is the solution of a highly transmittable virus that ’s being carry by parasitic tinge .
Early last yearwe reported that clothianidin , an insecticide sold in the USA , disrupts the nervous system of worm , head it to be a prime suspect in the mass death of honey bees . And just a few months agowe reportedon a Science clause reaffirm the suspicion that insecticide , particularly neonicotinoids , may be responsible .
Do people know perfectly well what ’s pour down bees ?
New Evidence that Our Insecticides are Killing Off the bee
But new enquiry coming out of Hawaii suggests that this may not be the event .
It turns out that the parasitic Varroa pinch – long known to torture honey bee populations – may be the culprit behind CCD . Or more accurately , it ’s the Deformed Wing Virus ( DWV ) that ’s being transmit by these mites that ’s stimulate all the bother .
The virus is transmitted between bees when they feast or mate . It ’s particularly tight in that it enters into a bee ’s bloodstream , make a young viral contagion route that electrical shunt many of the bees ’ natural defensive roadblock . DWV , which has only 9 factor , is like in anatomical structure to polio and the foot - and - mouth virus .
The research , which was conducted in Hawaii by investigator at Sheffield University , the Marine Biological Association , FERA and University of Hawaii , show that Varroa increases the relative frequency of DWV in bee colony from 10 % to an dumfounding 100 % . accompany this is a million - fold addition in the number of virus particle infecting each honey bee and a monolithic reduction in viral strain diverseness . It ’s this combination of factors that is head to the emergence of a single virulent DWV strain .
Disturbingly , the researchers are describe that the jot is permanently altering the dear bee viral landscape in Hawaii , a trend that they trust is being mirrored across other parts of the planet . Their finding suggest that this could be a cardinal gene in excuse the prevalence and devastation of dependency collapse disorderliness around the worldly concern .
