Neonicotinoids are a group of insecticides used widely on farms and in urban landscapes. They are absorbed by plants and can be present in pollen and nectar, making them toxic to bees.
Do neonicotinoids kill bees?
ӧ Neonicotinoid residues found in pollen and nectar are consumed by flower-visiting insects such as bees. ӧ Direct contact from foliar applications of the most toxic neonicotinoids has caused bee kills; additionally, foliar residues on plant surfaces may remain lethal to bees for several days.
What is the number one cause of death for bees?

What are neonicotinoid pesticides used for?
Neonicotinoids are used to manage many honeydew-excreting pests, which are primary pests in most agricultural systems, including field crops, vegetables, fruit and nut production, tree plantations, and urban forests, suggesting that neonicotinoids used in these systems have strong potential to pass to nontarget species …
Is Neonicotinoid banned?
In May 2013, the European Commission (the EU’s executive branch) banned the use of three neonicotinoids—imidacloprid, thiamethoxam and clothianidin—on flowering crops attractive to pollinators as well as cereals. This is because EU regulation on pesticides has built-in wriggle room.
How many bees have died from neonicotinoids?
Exposure to pesticides containing neonicotinoids and fipronil caused the deaths of more than 500 million bees in four Brazilian states between December 2018 and February 2019, according to an investigation by Agência Pública and Repórter Brasil.
What will happen if bees go extinct?
Without bees, the availability and diversity of fresh produce would decline substantially, and human nutrition would likely suffer. Crops that would not be cost-effective to hand- or robot-pollinate would likely be lost or persist only with the dedication of human hobbyists.
What is causing bees to go extinct?
There are three main reasons for the bees’ extinction and they are parasites, habitat loss, and cell phones.
Why the bees are dying?
Scientists know that bees are dying from a variety of factors—pesticides, drought, habitat destruction, nutrition deficit, air pollution, global warming and more. Typically, a bee hive or colony will decline by 5-10 percent over the winter, and replace those lost bees in the spring.
