A study done by British researchers shows that bees can get sick and recover after the immune system actively fights off viruses or parasites. Researchers said on Wednesday that bumblebees can get ill and seems to lose a bit of their buzz in that duration.

Like humans, the bee will also have a tougher time doing daily tasks when it's sick, and will revert back after recovery. However, the study also finds that bees have memory problem when the immune system kicks into action. This might be a huge problem since most bees fly to places where their memory tells them food is at (through scent).

Honeybees with activated immune systems also have memory problems, according to evolutionary biologist Eamonn Mallon of the University of Leicester, who said his findings can boost efforts to save dwindling bee colonies.

"This is an animal that lives on its memory," he said. "If even a minor infection hurts its memory that is a major cost."


This was how the research went:

The researchers divided bees into two groups and injected half with a substance that stimulated the immune system. They then offered the bees the choice of blue and yellow flowers but only one color contained sugar water.

Eventually all the bees spent their time feeding from the correct flower but it took the stimulated bees 10 percent longer to reach this point, showing that an active immune response when ill affects memory, the researchers said.

Maybe this is one of the reasons, apart from the farming methods that have deprived bumblebees of their traditional food sources, that explains why bumblebee populations are declining and under threat.

Three of Britain's 25 native species of bumblebees have been lost in the past fifty years, with several under threat. However, sickness in bees most likely have prevailed for thousands of years. There is certainly a lot of ambiguity when one is trying to find out why the bee population is declining. We should watch out for more possibilities in upcoming studies.

Why did the bees go on strike?
Because they wanted more honey and shorter working flowers!

Don't quite get this. Why did the bees who had the stimulus taker longer? Were they sick because their immune system had been stimulated or was it to simulate an illness that they were injected?

My garden is filled with flowers that attract insects. I purposely plant, shade, sun and water my garden to provide the ultimate attraction for insects.

This happy bumble bee is pollinating my dahlia flower in San Luis Obispo, California. This bumble bee is not sick today!! We have lots of bumble bees in our garden and they seem to work hard even in the early morning when the honey bees are still back in the hive. Bumble bees are welcome in my garden!!

Bombus Impatiens, the Common Eastern Bumblebee. There is one other species I'm trying to photograph currently in the yard. Here's a great site to help you ID them, even if you're not in Illinois.

Currently I'm obsessed with taking pictures of non-social wild bees, along with the bumblebees and honeybees.

A North American bumblebee busy pollenating in a botanical garden in Ringwood, New Jersey. With the lack of honey bees this year, these fellows have been picking up the slack and doing most of the job.

This is a bumblebee photographed near Des Moines, Iowa. It is crawling around a common thistle in a pasture. Though the blooms are extremely beautiful, the plant is intrusive to grazing areas, hard to eradicate, and painful to the touch.

Actually, I did not know bees could get sick. This really is interesting.

My bumble bee was still buzzing, so I think it is still alright.

Very interesting coverage of a topic that definitely needs more in-depth study.  Not many people realize how important the honeybees are to our environment & existence. 


I captured this bee hard at work and coated with pollen along the Foss Waterway in Tacoma, WA.  We were amazed at how much pollen it was carrying!

Bees have been in the news recently with the hive death syndrome in the US threatening agriculture and the diversity of bumble bees in decline everywhere. Many people do not realise, or do not often think about, just how dependent we are on these complex, usually social, insects. In Europe it has become common to see bumble bee nest boxes in parks along with bird boxes. It's possible to equip your own garden with nest sites - they only need holes such as in dry stone walls and log piles, but you can make more effective nest sites by burying a porous narrow-necked china bottle or jug up to the neck in earth - look for online sources of information on this.

Bees are members of the Hymenoptera, a group which provides an interesting test of evolutionary theory, as in this one group three lineages have evolved eusocial (hive) behaviour independently at least once - the ants, bees and wasps. The peculiarity which leads to this is haplodiploidy - the females are diploid, having pairs of chromosomes, but the males develop from unfertilised eggs and are therefore haploid, having only one set of chromosomes. This means that, assuming that the queen mated with only one male, the workers share 3/4 of their sisters' genes but only 1/2 of their daughters'. This generates a bias to cooperate with the reproduction of their sisters and predicts that the Hymenoptera should have a strong tendency to evolve colony-formation and sibling altruism.

The bumble bee shots were taken hand-held with a Konica-Minolta A200 in macro and auto-exposure modes, on a sunny day in Überlingen am Bodensee.

This was taken in my front garden... I've always strived to get a decent photo of a bumble bee...

This isn't too bad, although far from perfect. I'm happy with the depth of field though..

These happy Greek bumblebees are from May 2005. In the meantime, though, bees of all kinds everywhere remain under threat from pollution, disease, and habitat destruction (fires, construction projects &c). Let's make sure bees will always be in the picture!

This bumblebee was captured on my trip through a Norwegian forrest this summer. Me and the bumbleebee had a long chase, with lots of shots, until it deceided to give me a pose long enough for me to capture the moment. Just love the furry, unbrushed look of it.

This is a Golden Bumblebee, found in the North Isles - this was on Sanday, one of the Northern Orkney Islands. I don't know much about them, but I do know they are quite rare. And vrey beautiful!

Lovely summer day in England. I belive the bee was working not taking the sun bath. Hard working bee. As most of the people are at holidays and you will not find doctors in hospital, MPs in there offices.

Reporting from London.

I took this photo on a very rainy day in the Highlands of Scotland. I was out walking by the riverbank and decided to take some shelter under a tree, when I spotted this very busy bumblebee on a wildflower.

While visiting Shaw Nature Reserve in Gray Summitt, Missouri I walked through a wildflower area and noticed so many bees. It's a welcome site as I hardly see any in my own yard any longer.
