Via The Japan Times: Device to catch 500 mosquitoes in 3 hours a hit amid Japan's dengue fever outbreak.
A low-priced device that can collect up to 500 mosquitoes in three hours and was developed by a former university professor in Nagoya has been drawing keen attention amid the spread of dengue fever in Tokyo parks.
The only way to curb infections is to reduce the number of mosquitoes, said Kenzo Iwao, a former professor of bioenvironmental engineering at the Nagoya Institute of Technology.
“I hope the trap can be placed at spots where people gather,” he said.
The black, triangular-shaped device measures about 40 cm long and is made from waterproof plastic cardboard. To a mosquito, the shape of the device resembles a crouched dog or cat.
It has a replaceable adhesive sheet attached to its surface that emits a smell similar to animals or human beings, drawing and trapping mosquitoes.
Iwao has been working to develop a mosquito-collecting device for more than 20 years, following a request from the Thai government.
His prototype did not sell well, as it was priced at as high as ¥100,000 [US$913]. But the latest version, Iwao’s fourth-generation device, costs an affordable ¥3,000 [US$27] and can be handled easily.
A firm established by the Nagoya Institute of Technology started selling the device on Aug. 1. It has drawn attention, selling 500 units to a variety of customers, including homes, kindergartens, factories and shrines.
