bonsoir
est ce qu il y aurais un bon englich men pour traduire en bon francaid ce texte sur nosema!!! merci !!cold extremes.
Nosema is the scourge of the beekeeping industry and I truly believe it is the route factor which is causing so much death and stress on our honeybee hives. Nosema is a fungal gut infection which latches onto the cell wall of the bees gut lining and injects itself into the bee where it carries out its vegetative process. The symptom most noticed by beekeepers is dysentery. Spotting of poop will appear inside and outside of the hive usually followed by death. What beekeepers do not usually associate Nosema with is mal nutrition and viral infection. With millions of spores infecting the host, the competition for available nutrients puts a higher demand on the bees to maintain a high quality diet. Through times of poor forage or dearth the bees can be put into a prolonged ‘starving’ state which compromises their immune system allowing other diseases to take hold. With the spores penetrating the bee’s gut lining, it creates a pathway for viral diseases to infect the bee. You can imagine the snow ball effect as infection increases as other types of pathogens are readily available for infection.
There is a lot of talk among beekeepers on the efficacy of Nosema monitoring because of the huge disconnect associated with hive spore counts and relating it to actual poor hive performance. Colonies can and will maintain a high level of health and performance even with a high infection with Nosema present. The point is looking at the entire picture to fully understand what that nosema infection actually represents. Alone, Nosema only represents a small issue, causing your hives some difficulty utilizing all its digestible food. The bees can still fly out and expel the spores and keep on top of the disease effectively though a shortened life span of infected adult bees is a concern. The concerning issues comes in when other compounding factors enter into the equation. Slight decrease in feed uptake creates competition for digested nutrients. Dirty mite loads carrying viruses expose the apiary to a ‘hive to hive’ spread of virus. The virus then uses opportunities like that of the nosema infection as an efficient mode of transmission to infect the bee’s system. That virus effectively exploits these conditions to effectively infect the bees system! Chalk brood, Foul Brood… drop a hit of pesticide into the equation and with a shortened adult life span all of a sudden your thriving hive has hit the skids.
I have been telling beekeepers to know their nosema counts as part of their disease severance plan. All pest pressures and other types of outside influence need to be considered to be able to create a well developed understanding on how it is having an influence on our hives. Our current health related issues in the bee industry is not a one thing or another type of problem. I challenge anyone who I hear point fingers to pesticides as being THE issue facing our bee industry to tell me their current pest levels in their hives. Most of these finger pointers have no idea of the diseases present and nutritional status of their hives…
salut mika
merci pour la rapidité !!
tu utilise quoi comme traducteur! j ai essayé avec sistran je crois !!! pas terrible.a+bonsoir
ca confirme bien ce que je pensais !!!!a+
