Wat weten we eigenlijk over bijensterfte en neonicotinoiden?

Heldere uitleg van de stand van kennis over het vraagstuk van bijensterfte en neonicotinoiden in een Studium Generale college van 90 minuten door Prof. dr. Jeroen P. van der Sluijs.

Update of the Worldwide Integrated Assessment (WIA) on systemic insecticides

The Task Force on Systemic Pesticides — an international group of independent scientists convened by the International
Union for Conservation of Nature — produced the world’s first comprehensive scientific assessment of the ecological effects of neonicotinoids in 2015. This landmark review, which considered more than 1,100 peer-reviewed studies, as well as data from manufacturers, identified clear evidence of harm to honeybees as well as to a large number of other beneficial species, including aquatic insects at the base of the food chain, soil arthropods such as earthworms, and common birds (by cascade effects).
In 2017, the Task Force updated its assessment to take into account hundreds of new peer-reviewed studies (published since 2014) on systemic insecticides in the environment and their ecological effects. The new assessment reveals broader impacts that reinforce the conclusions of the original 2015 review: neonics and fipronil represent a major worldwide threat to biodiversity and ecosystems/ecosystem services.
The 2017 update is now published in the scientific journal Environmental Science and Pollution Research in 3 parts.

Summary: Highlights from the 2017 update to the Worldwide Integrated Assessment of the effects of systemic pesticides on biodiversity and ecosystems

Part I Part 1: new molecules, metabolism, fate, and transport

Part 2 Part 2: impacts on organisms and ecosystems

Part 3 Part 3: alternatives to systemic insecticides

Worldwide Integrated Assessment of the Impact of Systemic Pesticides on Biodiversity and Ecosystems

The Worldwide Integrated Assessment of the Impact of Systemic Pesticides on Biodiversity and Ecosystems (WIA) has examined over 800 scientific studies spanning the last five years, including industry sponsored ones. It is the single most comprehensive study of neonics ever undertaken, is peer reviewed, and published as free access so that the findings and the source material can be thoroughly examined by others.

Global scientific review reveals effective, affordable alternatives to neonicotinoid and fipronil insecticides

Report finds systemic pesticides not as effective as once thought, cites pest resistance as key reason to end mass uses of the harmful substances.

Overview
A new study published in the academic journal Environmental Science and Pollution Research calls into question the value of neonicotinoid insecticides (“neonics”) in agriculture. The research, conducted by the international Task Force on Systemic Pesticides, reviews more than 200 studies on the performance of neonics in controlling a wide range of insect pests on agricultural crops worldwide, including corn, wheat and many types of fruits and vegetables, as well as the available alternatives.

Neonicotinoid pesticides are a huge risk – so ban is welcome says EEA

The European Commission has decided to ban three neonicotinoid insecticides. These chemicals can harm honeybees, according to a large body of scientific evidence, so the European Environment Agency (EEA) commends the precautionary decision to ban them.
