Are Robo Bees the Answer to Bee Decline?

Posted under  Better Planet, Nature's Path on
Bees are vital to the health of all life on Earth. They are responsible for pollinating 70 per cent of vegetable, fruit and nut plants. They also pollinate 80 per cent of all plants, which act as food, shelter, and nesting sites for wildlife. It is normal for beehives to lose 5-10 per cent of a population over winter, but that number has risen to as much as 50 per cent in recent years. Bee reproduction is not keeping up with winter die-off. Consequently, their numbers are falling. This is a crisis since bee loss is the equivalent of food loss. Bee decline is caused by pesticide use, habitat loss from monoculture and construction, erratic weather patterns, flooding, drought, wildfires, and extreme weather events associated with climate change. Pesticides affect pollinators physiologically and neurologically. After exposure, bees will not develop properly as they grow, and their ability to learn foraging and flower identification gets impaired. If they can’t find flowers, they can’t pollinate them. Pesticides can also reduce the number of eggs queen bees lay. So is there a fix?


The simple solution seems to be ecosystem restoration and maintenance and getting back to organic farming. Excessive and unnecessary pesticide use needs to stop, and habitat needs to be planted. In Europe, farmers are experimenting with strips of wildflowers on the edges and interiors of large fields. Bees find the flowers and in turn pollinate the surrounding crops. This is a sensible and natural solution to bring bees back to sustainable numbers. The Garden Media annual Garden Trends Report predicts that robo farming will become more mainstream. Drones and robots are being developed for all phases of a growing season - planting, weeding, watering, and monitoring for soil moisture, insects, and disease. Automation can be a cost-effective way to monitor and maintain a farm. Send out a drone instead of using man-hours to walk or drive the long distances of large farms. That seems practical. Because we live in such a tech-driven society, it was inevitable that someone would come up with a tech solution to bee decline - robo bees. From Japan to the Netherlands and, closer to home, Harvard, Savannah, and Walmart, experiment with drone bees. And pollination are in full swing. Some of these gizmos look like tiny drones, and others more closely imitate actual bees with a body and wings. They are programmed to move from one flower to the next, vibrating enough for the flower to release pollen. Surface design attracts and holds the pollen to be deposited on the next flower, just as bees do.

Is it practical?

This may seem ideal, but for robo bees to meet the need for the scale of necessary pollination seems impossible. Billions of bees are brought to California to pollinate the almond crop every year. That is a lot of drones to be manufactured, monitored, and maintained. They also need to be remotely controlled and programmed to exactly hit the flower they are intending to pollinate. In the Netherlands, drone bees are being developed to pollinate crops grown in greenhouses, a smaller and more workable area than millions of acres of field. As greenhouse production gains in popularity to combat erratic weather patterns, robo bees could be a viable solution to pollination. Drone bees need to be fine-tuned and financed. They wouldn’t be widely available for many years, but could be part of a solution to a huge problem. A more sensible and cost-effective way to make sure our food crops are being pollinated, though, is to encourage bees to visit farms, by offering them the food and shelter they need.
