Mosquito

The whine of a mosquito is not just annoying. In some regions it’s menacing. Mosquitos can carry serious diseases such as Zika and Dengue, which are spreading.

Roberto Barrera at the Centers for Disease Control and Prevention in Puerto Rico says we need better ways to control mosquitoes. So he’s invented a new trap with simple components: a bucket, hay, a screen, and water. Inside a special chamber …

Barrera: “… there is a sticky board with a special insect glue.”

Barrera and his team installed traps at the majority of houses in four urban areas in southern Puerto Rico. Each house received three traps. He found that they reduced the population of one mosquito species by almost 80 percent.

The bucket traps are chemical free and Barrera says they could be used with other methods of mosquito control.

Barrera: “They can be used as an alternative in areas where the mosquito has developed resistance to insecticide.”

Mosquitoes thrive in warm, wet conditions, which are expected to increase as the climate changes. That means new approaches like Barrera’s traps could be critical to reducing mosquito-borne disease.
