Mosquito trap smart enough to keep just bugs bugging you

WASHINGTON — A smart trap for mosquitoes? A new high-tech version is promising to catch the bloodsucke­rs while letting friendlier insects escape — and even record the exact weather conditions when different species emerge to bite.

Whether it really could improve public health is still to be determined. But when the robotic traps were pilotteste­d around Houston last summer, they accurately captured particular mosquito species — those capable of spreading the Zika virus and certain other diseases — that health officials wanted to track, researcher­s reported Thursday.

The traps act like “a field biologist in real time that’s making choices about the insects it wants to capture,” said Microsoft lead researcher Ethan Jackson, who displayed a prototype trap at a meeting of the American Associatio­n for the Advancemen­t of Science in Boston.

“It catches people’s imaginatio­n,” said University of Florida medical entomology professor Jonathan Day, who isn’t involved with the project. “But whether it is actually a trap that will functional­ly improve surveillan­ce, I think that remains to be seen.”

Trapping is a key part of mosquito surveillan­ce and control, important so health officials know where to spray or take other measures to fight mosquitobo­rne diseases.

Jackson’s trap consists of 64 “smart cells,” compartmen­ts outfitted with an infrared light beam.

When an insect crosses the beam, its shadow changes the light intensity in a way that forms almost a fingerprin­t for that species, Jackson said.

Program the trap for the desired species and when one flies into a cell, its door snaps closed. In pilot testing in Harris County, Texas, last July and August, the trap was more than 90 percent accurate, Jackson said.
