Scientists in New Zealand are developing drones and small radars1 to follow insects to try to protect threatened species2.

The new technology involves attaching radars to the insects to follow their movements. The devices3 connect electronically to drones that will track the insects in real-time. The scientists are with the University of Canterbury on New Zealand's South Island.

The team says it hopes the technology will lead to a deeper understanding of the country's troubled insect populations.

The research builds on years of experience in the area of bird conservation, in which radio tracking methods have helped to protect many threatened species. But that technology had to be made much smaller for use on insects.

The researchers have now made about 20 small "harmonic" devices that can be attached to insects. The insects can then be tracked over wide areas by drones.

Steve Pawson, from the university's College of Engineering4, told VOA that bird-tracking technology is what made the researchers start looking for a similar solution to follow insects.

The information from tagged birds, Pawson said, "really informs conservation management."

The same system can help scientists learn more about many different insect behaviors, he added, like how far they move, where they look for food, and even, how long they live.

"If we have that knowledge, then we can incorporate5 it into our decision making and our planning for conservation management operations," Pawson added.

The researchers plan to begin tests of the system on ground-based insects before moving to the greater complexities6 of tracking insects in flight. They hope to begin field testing by 2023.

The team says the research could possibly be useful in other scientific fields as well, such as biosecurity or medical imaging.

Among New Zealand's endangered insects is the widely recognized Wētā. The creatures -- native to the South Pacific --have large bodies, legs with sharp points and rounded tusks7.

Several species of Wētā are under threat from animals that eat them and destruction8 of the places where they live.
