(Reuters)-Australian scientists are attaching tiny sensors to thousands of honey bees to track their movements in a trial aimed at stopping the spread of diseases that have wiped out populations in the northern hemisphere.
Scientists at the Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia's national science agency, said the chips could help follow socalled colony collapse disorder, a situation where bees mysteriously disappear from hives, and the invasion of other harmful insects.
Scientists will use a small tool to glue on the sensors, weighing about 5 milligrams and measuring 2.5 millimeters square, after leaving the bees to sleep by refrigeration. Some young bees, which tend to be hairier than older bees, need to be shaved before the sensor can be glued on. Scientists will examine the effectiveness of pesticides(害虫) in protecting the bees from colony collapse disorder.
The study will also enable farmers and fruit growers to understand and manage their crops, given the honey bee's important role in the pollination(授粉) of crops globally, the CSIRO said in a statement issued on Wednesday.
“Honey bees play a vital role in the landscape through a free pollination service for agriculture, which various crops rely on to increase yields，” the CSIRO's Paulo de Souza, who is leading the project, said in the statement, “Using this technology, we aim to understand the bee's relationship with its environment.”
Scientists plan to fit sensors on 5,000 bees in the southern island state of Tasmania over the Australian summer. The radio frequency identification sensors work like an electronic tag for cars on a toll road, recording when insects pass a checkpoint. That will allow scientists to build a threedimensional(三维) image of the insects' movements, a process described as “swarm sensing”.
The scientists are working on shrinking the sensor to 1 mm square so they can be attached to smaller insects, including mosquitoes.
