Wild Bees Are Good For Crops, But Crops Are Bad For Bees
by Dan Charles, NPR March 1, 2013


the article in part:

"Some of the most healthful foods you can think of — blueberries, cranberries, apples, almonds and squash — would never get to your plate without the help of insects. No insects, no pollination. No pollination, no fruit. Farmers who grow these crops often rely on honeybees to do the job. But scientists are now reporting that honeybees, while convenient, are not necessarily the best pollinators.

A huge collaboration of bee researchers, from more than a dozen countries, looked at how pollination happens in dozens of different crops, including strawberries, coffee, buckwheat, cherries and watermelons. As they report in the journal Science, even when beekeepers installed plenty of hives in a field, yields usually got a boost when wild, native insects, such as bumblebees or carpenter bees, also showed up.

"The surprising message in all of this is that honeybees cannot carry the load. Honeybees need help from their cousins and relatives, the other wild bees," says Marla Spivak, a professor of entomology at the University of Minnesota. "So let's do something to promote it, so that we can keep honeybees healthy and our wild bee populations healthy."
