Commercial bees are the workhorses of modern agriculture, as they pollinate vast fields of crops on their quest for tasty nectar. And since they’re already making the journey from hive to stamen, says Les Shipp, a scientist for Agriculture and Agri-Food Canada, why not piggyback on their efforts even more? Shipp and his colleagues have worked out a way to get bees to carry pesticides right to where they need to be.
In an interview, Shipp explained to the CBC how his pest control-bees work:
What we have is a little tray, we have an inoculum tray that we attach to the hive. And, as the bees exit the hive they walk through this tray, picking up the inoculum on their hairs and on their feet. And then they leave this inoculum tray, go out to the plants and fly around, and when they’re buzz pollinating—they’re grabbing that flower and they’re vigorously shaking that flower—they’re releasing this inoculum on the flowers, and also it gets on the leaves too.
The pesticides and anti-fungal agents and other things that Shipp has coaxed the bees into carrying aren’t dangerous to the bees themselves. And, he says, this type of targeted delivery could actually help cut down on the amount of pesticides that end up blowing in the wind.
