As a gardener or landscaper, you’ve probably already become aware of the disappearing honey bees. Along with this has come a boatload of theories as to why. Cell phone usage, global warming, sunspots, UFOs, terrorist plots, insecticide use, Russian scientists gone mad, etc. etc. etc.
Most of these theories do not have enough merit to even comment upon because they are so ridiculous, except for one: insecticide use. But in this case, it is a lack of insecticide use that may well be the cause.
Our bee population has had a problem with the varonna mite over the past several years. Most bee keepers were aware of this problem and most have been treating for this infestation. The key word is “most bee keepers”. Some have not.

There are basically 2 types of honey bee colonies in America: commercial or hobbyist types of colonies, and natural bee colonies that live in hives they create on their own.
The hobby bee keepers are usually small scale with hives they maintain on their property year round. However, the commercial bee keepers are much larger and they move their colonies around the country 1000s of miles during the year as they follow the blooming cycle of different plants. They are paid by farmers to set up their hives on their farm so many dollars per hive. This is done so there will theoretically be enough bees to help pollinate their crops so the farmer will be insured their fruit crops will be adequately pollinated.
Now, imagine one commercial bee keeper’s hive becomes infected with a veronna mite infestation and he does not know it. This mite infection usually can only be detected with a large infestation. Smaller infestations may well go undetected. Here is the problem: an infected hive, say in Florida, is moved north as the season progresses. Every day the infected bees leave the hive and go out and do what bees do– they pollinate flowers, along with the 1000s of other bees from local natural bee hives. These local bees then pick up this varonna mite and take it back to their natural bee hive. In time the varonna mite sucks the life out of the hive since there is no insecticide controls around to kill the mite in these hives. The cycle repeats itself over and over and soon we are faced with “a great honey bee mystery.”
I don’t know if the varonna mite is the sole problem. It is very likely to be the case. If it’s not the varonna mite, then it could very easily be some other problem similar to that and spread in the exact same way already described. What we are faced with is an adjustment period. In time, a new breed of honey bees will arise that is resistant to whatever the infestation cause is. It will take time.
