In 2007 reports of โcolony collapse disorderโโswift, terrible deaths of entire coloniesโsuddenly mushroomed across Europe and the Americas. News reports called it a โthreat to global agricultureโ and an โunprecedented catastrophe for the planet.โ The headlines were justified: Insect pollination, mostly from honeybees, is critical to one-third of the worldโs food supply.
A potentially nontoxic treatment is envisioned by Beeologics, an arm of the agribusiness giant Monsanto, which uses RNAi (the last letter stands for โinterferenceโ). In the Beeologics version, bees would be fed sugar water containing RNAi, which disables mite RNA. In theory the doctored sugar water should not affect the bee. But when mites drink the beesโ hemolymph, the mites will also take in RNAiโand it should affect them. Itโs as if you could kill vampires by eating pizza with garlic sauce.
Jerry Hayes of Monsanto Honey Bee Health hopes to have something on the market within five to seven years.
A consortium of more than a hundred researchers decoded the honeybee genome in 2006. Geneticist Martin Beye at Heinrich Heine University in Dรผsseldorf, Germany, was part of the group. The next step, in his view, would be to identify genes that influence certain behaviorsโand, if needed, modify them.

Although scientists had produced transgenic insects since the early 1980s, all attempts to insert genes into Apis mellifera had failed. With Beye and two other collaborators, Christina Vleurinck gradually developed a successful technique. Still, it will take years of work before the method can be used to develop a better bee. And releasing genetically modified bees is bound to be controversial.
