James Cook University scientists have discovered a common honey bee disease can be deadly to native Australian wild bees and can be transmitted by flowers—the first time this link has been made.

JCU's Associate Professor Lori Lach oversaw the study investigating the susceptibility of Australian stingless or "sugar bag" bees to Nosema ceranae—a parasite that causes European honey bees to become less active, develop an increase in appetite, and die prematurely.

"Pathogen spillover from bees kept by bee keepers to wild bee populations is increasingly considered as a possible cause of wild pollinator decline. Spillover has been frequently documented, but not much is known about the pathogen's virulence in wild bees or how long pathogens can survive on a flower," said Terence Purkiss, the honors student who conducted the study.

[...] "About two thirds of the flowers exposed to infected European honey bees were found to be carrying Nosema ceranae spores. In every case, at least one stingless bee that foraged on the flowers contracted the pathogen. What this means is that wild bees can be infected with the disease by sharing a flower with an infected European bee ," said Dr. Lach.

Five out of the six stingless bee hives the researchers monitored over five months tested positive for the pathogen at least once.

    pond dwelling creatures' diseases spread through water, what other astounding scientific "discoveries" await in today's publication pile?

    Or Israelite moon landers, as one of the yesterday's publication pile [soylentnews.org] revealed.
