The phenomenon is particularly important for crops such as almond growing in California, where honey bees are the predominant pollinator and the crop value in 2006 was US$1.5 billion. In 2000, the total U.S. crop value that was wholly dependent on honey bee pollination was estimated to exceed US$15 billion.^[79]

Honey bees are not native to the Americas, therefore their necessity as pollinators in the US is limited to strictly agricultural/ornamental uses, as no native plants require honey bee pollination, except where concentrated in monoculture situations—where the pollination need is so great at bloom time that pollinators must be concentrated beyond the capacity of native bees (with current technology).

They are responsible for pollination of approximately one third of the United States' crop species, including such species as: almonds, peaches, soybeans, apples, pears, cherries, raspberries, blackberries, cranberries, watermelons, cantaloupes, cucumbers and strawberries. Many but not all of these plants can be (and often are) pollinated by other insects in small holdings in the U.S., including other kinds of bees, but typically not on a commercial scale. While some farmers of a few kinds of native crops do bring in honey bees to help pollinate, none specifically need them, and when honey bees are absent from a region, there is a presumption that native pollinators may reclaim the niche, typically being better adapted to serve those plants (assuming that the plants normally occur in that specific area).

However, even though on a per-individual basis, many other species are actually more efficient at pollinating, on the 30% of crop types where honey bees are used, most native pollinators cannot be mass-utilized as easily or as effectively as honey bees—in many instances they will not visit the plants at all. Beehives can be moved from crop to crop as needed, and the bees will visit many plants in large numbers, compensating via sheer numbers for what they lack in efficiency. The commercial viability of these crops is therefore strongly tied to the beekeeping industry.

Ironically, in some of the crops listed above, studies have shown that while the farmers pay for honeybee "pollination", in fact native pollinators do almost 100% of the work, the farmer's money being wasted. For example, cucurbits like cucumbers, melons, and squash are all pollinated within a few hours of sunrise by squash bees, before honeybees are even active for the day. Since female cucurbit flowers bloom days after the male ones, the cucurbit-loyal squash bees also are able to correctly deposit the pollen days later, while the honeybees may have dispersed most of the pollen to non-squash plants by then.[15][16]

Materials Needed:

Flexible tubing that is three feet long

Cotton

two and a half gallon bucket

Step one

Find a place to put your bumblebee box. Make a hole in the ground that is four to six inches deep and put the bucket in it with the bottom facing up.

Step two

Make a big enough hole in the side of the bucket. Put cotton inside the bucket. Do not put a lot of cotton in the bucket because it will get in the tubes and clog them up so the bumblebees will not be able to get in.

Step three

Take the three to four feet long tubing and stick it through the hole in the bucket and dig a hole big enough for the tube so it looks like the tube is going under ground because the bees like their homes under ground. This is so the bees can get into the bucket.

Step four

You have finished your bumblebee habitat!
