Pollinators their survival is threatened- World .

The latest data shows that 30 percent of honeybee colonies perished last winter. Researchers have developed new technologies that could change how beekeepers manage their hives. Here are four emerging tech tools aimed at helping beleaguered bees.

Meadow mics

Researchers placed small microphones in alpine meadows to record the buzzing of bees. According to the 2017 study, the acoustics allowed scientists to gauge the number and species of bees in the meadows. Researchers hope that farmers could place microphones in their fields to monitor the pollination of fruits, vegetables and nuts and, in the absence of sufficient bee activity, rent additional hives.

BuzzBox

For $199, beekeepers can attach sensors to their beehives that monitor sound signatures, which can signal issues like missing queens, swarming and parasites. The BuzzBox hive health monitor sends alerts via smartphone app if something is amiss. “Early detection is the next best thing after prevention,” says Aaron Makaruk, co-founder of OSBeehives, the start-up behind BuzzBox.

Thermosolar hive

Chemical treatments are the first defense against the Varroa mites that decimate bee colonies. Czech beekeeper Roman Linhart designed a beehive with a rooftop solar panel that heats up the interior of the hive to temperatures that can be tolerated by bees but not Varroa mites. A 2016 crowdfunding campaign raised more than $70,000 for the project; the patented hives were sent to backers who pledged at least $650. The Thermosolar Hive isn’t yet available to the general public.

Robot bees

If honeybee populations plummet, drone pollinators could pick up the slack. Designs for robot bees are varied: Japanese scientists retrofitted a drone with gel-coated horsehair bristles to collect pollen grains, while the RoboBee developed at Harvard University has flapping wings. The working prototypes are a good “plan B,” according to Shashi Shekhar, a computer science professor at the University of Minnesota. “If there are unanticipated surprises or if other measures of protecting bees aren’t effective and we have a real shortage of bees in the future, we’ll need artificial pollinators,” says Shekhar.
