Honey Bee

Researchers have found the cause of possible increase in the deaths of the honey bees these days.

This research has been published online in the American Chemical Society‘s Environmental Science & Technology journal.

This research provides insight into the colony collapse disorder or the mass die-off of honeybees.

This research shows that neonicotinoid insecticides “are among the most widely used in the world, popular because they kill insects by paralyzing nerves but have lower toxicity for other animals.” Beekeepers found die-offs at the time of corn planting while using this specific kind of insecticide.

Researchers are of the opinion that the released particles of insecticide into the air by the machines at the time of spray could be the cause of the honeybees’ mass die-offs. They used different ways to use the chemical, so that coating could be achieved on the seeds but they found that the mass die-off was continuous on the use of the neonicotinoid insecticides.

Honeys bees are important in pollination of food crops and their mass die-off would harm the entire ecosystem. The researchers wrote in the study, “In view of the currently increasing crop production, and also of corn as a renewable energy source, the correct use of these insecticides within sustainable agriculture is a cause of concern.”
