The Effects Of Neonicotinoids On Bees
Neonicotinoids, nicotine-similar pesticides, threaten bee populations, which pollinate agricultural crops, ensure food security and maintain biodiversity. Scientists Sebastien Kessler and Maj Rundolf sought to understand pesticide effects on bees. Through a laboratory study, Sebastien Kessler tested abilities of honeybees and bumblebees to taste common neonicotinoids. Unlike Kessler, Maj Rundolf assessed neonicotinoid impacts on bee colonies’ near canola fields. Each scientist had a unique plan. Kessler introduced both bees’ species to neonicotinoid-treated (realistic dosages) and untreated-sugar water. Neither species avoided treated solutions, rather preferred it to untreated solutions, indicating bees weren’t able to taste neonicotinoids.

    The Vanishing Bees

    There are more than 20,000 bee species known around the world, with the honeybee being the most common. These important bees are disappearing rapidly (Lynn Hermann, 2011). Honeybees are the most important pollinator on the planet. In North American, a third of fruits, nuts, and vegetables require pollination of the honeybee (Seeley, 3). The loss of our black-and-yellow pollinators would mean the serious decline of agricultural products, which directly threatens civilization’s food supply. Research has linked several factors to the rapid decline in honeybees; these factors included over use of chemically treated crops, the Colony Collapse Disorder, and environmental factors.…

    $9 billion of agriculture is pollinated by bees annually (Karimi). Bees pollinate many plants around the world, some of these plants grow fruit, nuts, and vegetables. The pollination process happens when bees transfer pollen from one plant to another so that the plants can make seeds and reproduce. Bee populations are rapidly declining. There are threats against the bee colonies which are causing a decrease in the population, including : pesticides, habit loss, wildfires, and monoculture. Some ways to stop the decrease is to make a pesticide that does not harm bees, decrease the amount of habitat loss, and plant more than one crop in an large agricultural area. Because bees are an essential part of the pollination process, saving theses black and yellowed stripped bugs is essential for the earth’s environment.…
