When Drone bees take over of the bee colony, how could the beekeeper possibly intervene? (Distinguish between 2 cases: A. Early detection B. Late detection)
Varroa destructor a mite parasite can kill the drone more easily and preferably that why to control the drone in later stage one can use this parasite.
In early state , the drone will be killed automatically by worker if they got less nectar and grains because normally , worker don't give sufficient food to drone and thus when their will be less supply they will not get any food . And eventually they will be died.
Thank you

“We should investigate further. Maybe something new about Colony Collapse Disorder has been found,” Mark said. He was worried, not only because of the effects this was having on the emotional and economic standing of his family, but for what this meant for pollinating honeybee colonies all over the United States. Tanya entered the room reading an article titled “Solving the Mystery of the Vanishing Bees” that she had found inScientific American. “Look at this excerpt from an article by...

A 29-year-old and a 68-year-old. How much could they possibly have in common? And what could they learn from each other? At Randstad USA’s Manhattan office, such employee pairings are common. One such pair of colleagues sits inches apart facing each other. “They hear every call the other makes. They read every e-mail the other sends or receives. Sometimes they finish each other’s sentences.” Randstad Holding NV, a Dutch company, has been using this pairing idea since its founding more...
