Simone Tosi, a postdoctoral researcher in biology at the University of California, San Diego, James Nie, a professor of biology, and Giovanni Bull, an associate professor at the University of Bologna in Italy, demonstrated for the first time that pesticides can damage the flying ability of bees
.
Related research papers have been published in the April issue of "Scientific Reports"
.
In the past, studies have shown that if bees consume nicotinic pesticides that are widely added to insecticides during foraging, they are unlikely to fly back to the hive, directly leading to the reduction of search team members in the colony
.
The new research takes the nicotine pesticide Actai as the research object, which is an insecticide commonly used in crops such as corn, soybeans, and cotton
.
In order to test the degree of pesticide damage to the flight ability, the researchers put Actai into the field where the bees fly, and ensure that the test environment is within a controllable range
.
A few months later, the researchers discovered that even if healthy bees found only a small amount of Actai in the flowers of crops, their flying ability would be extremely impaired
.
The main effect after ingestion is that the flight distance, flight time and speed of bees are all weakened
.
Especially after being exposed to pesticides for one to two days, bees will be very active in a short period of time and fly farther, but after long-term observation, their flying ability will be greatly reduced, and the flight will tend to be irregular
.
Bees rely on flying ability to survive, especially after discovering nectar sources, they need to "dance" to convey the location information of nectar sources.
Therefore, flying ability is actually the only way for bees to collect food
.
Although nicotine pesticides will not kill bees immediately, they can cause irregularities in long-distance flight of bees, thereby disrupting the social stability of the bee colony and causing lethal damage to the bee colony
