Neonicotinoid traces in honey – Expert Reaction

Sarah-Jane O'Connor posted in on October 6th, 2017.

A global study of honey found 75 per cent of samples had traces of neonicotinoid pesticides, which have been implicated in the global decline of pollinators, particularly bees. Published today in Science, the research found concentrations of the pesticide were below the amount authorised by the European Union for human consumption. Concentrations were highest in […]

Warming puts the squeeze on bumble bees – Expert reaction

John Kerr posted in on July 10th, 2015.

A new comprehensive study, published in Science, tracks the impact of climate change on bumblebees, finding global warming is rapidly shrinking the area where these bees are found in both North America and Europe. Researchers examined more than 420,000 historical and current Northern Hemisphere records of many species of bumblebees–and confirm that the critical pollinators […]

Wild pollinators crucial – experts respond

John Kerr posted in on March 1st, 2013.

A massive international study of 600 field trials from around the globe (including New Zealand) highlights the importance of wild insects in spreading pollen for agricultural crops, and warns of excessive reliance on honeybees. The study, published in Science, found that wild insects pollinate crops more effectively than managed honeybees, leading to twice as much […]

Pesticide harms bees at ‘safe’ levels – experts respond

John Kerr posted in on March 30th, 2012.

Two new studies published in Science this week show that honey and bumble bees are negatively affected by a widely-used class of pesticides – even at supposedly safe doses. The pair of research articles examines the effects of neonicotinoid pesticides, insect neurotoxins which were introduced in the early 1990s and have now become one of the […]
