Foreign media said that a new study in New Zealand showed that the pesticide "chlorpyrifos" (chlorpyrifos) can make bees "dumb"
.
This discovery can explain to a certain extent the phenomenon of the decrease in the number of bees worldwide
.
According to a report on the website of Singapore’s "Lianhe Zaobao" on March 7, researchers from the University of Otago in New Zealand recently announced the results of the study.
As long as a small dose of "chlorpyrifos" is ingested, bees may suffer serious learning and memory deficits, and even A direct threat to the survival of bees
.
According to the report, the researchers selected 51 hives in 17 locations in the Otago region of New Zealand's South Island as the study samples, and traces of "chlorpyrifos" were detected on bees in 6 hives in 3 locations
.
The researchers also exposed the bees in the laboratory to the same dose of "chlorpyrifos" as in the natural environment.
Even if this dose is not enough to kill the bees, their ability to find odors and recall familiar odors is significantly worse
.
Bees rely on their own memory of smells to find flowers
.
Once exposed to a small amount of "chlorpyrifos", this ability is significantly degraded, thereby threatening the survival of bees
.
According to the report, "Chlorpyrifos" is an organophosphorus insecticide.
Because it can effectively kill crop pests, it is used all over the world
.
Previously, researchers from the school found that even in areas where “chlorpyrifos” has not been sprayed, “chlorpyrifos” can still be found in air, water, and plant samples, indicating that this pesticide has a strong ability to spread over long distances
