bẫy pheromone tình dục có thể giúp Mỹ ngăn chặn sự lây lan của 'ong bắp cày'... :)

“Murder hornets” have been a not-so-tiny terror (sự kinh hoàng, sự khiếp sợ) plaguing the western United States over the last few years. Now, scientists may finally have a way of trapping these insects before they devastate (tàn phá, phá hủy, phá phách) local bee colonies. Researchers say sex pheromone traps could help stop the Asian giant hornet from invading more states and wreaking havoc.


A team from the University of California-San Diego says stimulating (kích thích) odors  (mùi hương) produced by a hornet queen (ong chúa) can bait (mồi nhử) and trap (bẫy) the invasive insects. Asian giant hornets, more commonly known as “murder hornets,” have been spreading across parts of North America and Europe.

While their nickname is misleading, they are threatening bee populations along with millions of pounds worth of crops. Honeybees, some of the world’s most important pollinators (thụ phấn), have few defenses against these destructive insects, which can quickly destroy an entire colony.

...The secret mix is the queen’s pheromone
The team identified three of the major chemicals found in the giant hornet queen’s sex pheromone, including hexanoic, octanoic, and decanoic acid. They then captured male hornets by laying traps near their nests and places where they typically reproduce.

The study finds the hornets’ brain activity and antennae were highly sensitive to the pheromone. Researchers add that it’s possible to easily purchase and deploy these compounds in the field immediately.
