Beekeeping Bee Colony Viral Diseases Treatment and Prevention
Posted on February 2, 2013
Amongst the viral ailments that might beleaguer a bee colony is Persistent Bee Paralysis. Resembling all of the various bee contaminations there is no cure or medicine that may well be made use of to take away the disease, the lone defensive measure is sanitation.
There are visibly defined warning signs of Recurring Bee Paralysis. The fully developed bees are the only ones affected by this. The symptoms are an abnormal trembling in the wings and body, the bee’s inability to fly which forces them to crawl on the ground and struggle up the blade of grass in front of the hive. The abdomens would be bloated and the wings would be partially spread or seem dislocated. The contaminated bees will appear shiny and oily because of the lack of hair, that has been confused with robbing bees.
What’s more, the infected grown bees are chewed on by the other bees and harassed by the guard bees at the entry to the hive, which is also confused with signs of robbing. Grown bees will die in a few days of the onset of the contamination. The infection is spread from bee to bee by means of lengthened physical contact or rubbing that causes many hairs to break revealing live tissue. The contamination can not be transmitted through food exchange of the bees. Many millions of virus particles are required to cause paralysis when given to a bee in food. If signs continue then it can be a good idea to requeen.
One more virus that bees are prone to is the Black queen cell infection. It is connected together with Nosema infection and causes the death of queen larvae or prepupae once their cells are sealed. Th larva will subsequently become black along with the walls of the cell. Treating colonies with Fumidil-B? to control Nosema might help keep prevent this infection.
The bee bred to be defiant to this infection may perhaps help minimize epidemic of this disease. Another method to cut down on the number of occurrences of the disease is to retain a warm, dry hive inside. If the hives are drafty, wet, lying in low parts or in heavily overgrown places, they are more susceptible to chalkbrood virus. Rain water ought to run out of the hive rather than accumulating, thus stand the hive with it leaning forward somewhat. If a hive gets moist, prop the top of the hive wide open to air out the interior. Old tools must be changed or fixed if they have huge holes that permit entry of dampness and drafts.
There is a chance of genetic susceptibility or old combs that are harboring spores of the virus if the colonies have chronic difficulties along with the infection that are not straightforwardly traced to season or management practices. Old combs must be changed occasionally to improve brood production.
