Honey bees are disappearing all over the world.  The loss is increasing: 15 percent 10 years ago reaching as high as 40 per cent today.  Oddly, production has not fallen  mainly because more apiaries are being established to counter losses.  This is despite reduced habitat due to building, pesticides, parasites, pests and pathogens.
Australian Varroa Resistant Bees
The main killer identified is the Varroa mite which latches on to bees during the formation process.  The mite is in most countries except Australia.  The "Australians" are being bred for introduction to other places.  Unfortunately, they do not do well in cooler climates.

Pesticides are suspected of causing bee decline.  It is recommended that pest chemicals only be sprayed at night when apis return to hives.  If one gets poisoned thousands can die when it goes back to the hive - if it gets that far.  Anyway, they forage in the same area so many succumb.

Genetic Improvement of Honey Bee Output

The worldwide threat to the survival of honey bees is still here, but work on improving honey production continues. Selection of the best queen bees ironically has not been done in the past. If breeding queens only of the highest yielding hives is done, output per hive could increase by a kilogram a year.
Genetic improvement to honey bee output by selection of only the best queen bees
Genetic improvement in cattle has not been a one-off. The gain is cumulative each year. For this gain to be achieved small producers will have to come on board so old poor stock will not be "kept alive". Tests show that the queen bee is the main depository of better genes. Input from males is relatively stable with little change.

External factors such as hive location and length of season do affect the quantity of honey, but gene selection would raise output overall. The Genetic Evaluation of Australian Honeybee report recommends the method of data collection and evaluation. Breeders must get into the habit of keeping data. The industry needs to be reformed away from small ad hoc production toward uniform management.

Bees Calculate Energy Expended When Getting Pollen

Bees calculate how much energy they need to get pollen. To survive, bees must run on a "profit" basis. They must not use more energy in obtaining nectar than energy the nectar provides. Bees were given the choice of travelling along two pathways to get nectar. One pathway was 10 meters long, the other 20 meters. However, the "scenery" of the 10 meter pathway was designed to trick the bees into perceiving that it was the furthest distance away.

When the bees returned to their fellows in the nest they told them with a waggle dance which pathway to use to get more pollen. Despite the 10 meter pathway appearing to the bees to be further away they told other bees to go to the feeder in the 10 meter pathway. Somehow, they had worked out that it used up less energy to go to this feeder than the one on the other pathway.

It is believed that bees have "calorimeters" built into their brains. They do not judge energy expenditure solely based on distance travelled. A partly covered pathway would be given the okay over a pathway out in the weather for example.

Bees are smart little critters and we can learn a great deal from them.
