Bees play a crucial role in the ecosystem of the world and the food supply, but bees are dying more rapidly than ever before. There are many factors to why bees are dying off; however, one of the main reasons is neonicotinoids. In the U.S, crops are planted with over 143 million acres of seeds filled with clothianidin and imidacloprid each year (Bleifuss). These are two of the most popular types of neonics used today on farmland. But neonics do not just affect the bees, they affect their hives as well. In 2006, many hives started to become empty, with all the bees vanishing or dead. This was called colony collapse disorder, or CCD. In a study by experts at Harvard School of Public Health, in cases when bees abandoned their hives near the winter …show more content…

Bees all over the world are being harmed by toxic neonicotinoids. First, in 2010, an experiment was done by the EPA’s Environmental Fate and Effects Division, and what they found was shocking. The experts said, “Acute toxicity studies to honeybees show that clothianidin is highly toxic on both a contact and an oral basis. ... Information from standard tests and field studies ... suggest the potential for long term toxic risk to honey bees” (Bleifuss). Because the seeds were being injected with neonics, there are many long terms effects that bees can contract from eating or even touching the neonics. Likewise, Christian Krupke, a professor of entomology at Purdue University Indiana did a study on the corn-planting machines on farms used with neonics and found staggering results. The professor said, “Krupke explained how he tested that planter exhaust and found amazing levels of neonic pesticides: 700,000 times more than what it takes to kill a honeybees. That toxic dust lands on nearby flowers, such as dandelions. If bees feed on pollen from those flowers, that dust easily can kill them” (Charles). Evidently with all of the machine dust floating in the …show more content…

First at Harvard University, associate professor of environmental exposure biology in the Department of Environmental Health Chensheng (Alex) Lu, held an experiment of 5 groups of beehives, four with different doses of imidacloprid, a type of neonic, and one hive without. They monitored the hives for 23 weeks to see if the bees would experience CCD. Lu said, “After 12 weeks of imidacloprid dosing, all the bees were alive. But after 23 weeks, 15 out of 16 of the imidacloprid-treated hives—94%—had died... The characteristics of the dead hives were consistent with CCD, said Lu; the hives were empty except for food stores, some pollen, and young bees, with few dead bees nearby... Strikingly, said Lu, it took only low levels of imidacloprid to cause hive collapse—less than what is typically used in crops or in areas where bees forage” The study shows that even small doses of neonics have a huge impact on bees, which can lead to CCD. All of the hive abandoned had experienced signs of CCD because of the neonicotinoids. Moreover, in an interview by Neal Conan with Dan Charles, NPR's food and agriculture correspondent, talked about how neonics had negatively affected bumblebees behavior. Charles stated, “there were some scientific studies that came out that indicated that it might actually change their behavior in subtle ways. So there was a study done with bumblebees, where the
