Country-specific effects of neonicotinoid pesticides on honey bees and wild bees

Field results confirm that neonicotinoids negatively affect pollinator health under realistic agricultural conditions. Read the full publication here.

Bee Experts Dismantle Touted 'Harvard' Neonics-Colony Collapse Disorder Study As 'Activist Science'.

Chensheng Lu was in his element last month at a speech before a green group at Harvard Law School. The School of Public Health professor was lecturing on his favorite topic--his only subject these days, as it has become his obsession: why he believes bees around the world are in crisis.

Lu is convinced, unequivocally, that a popular pesticide hailed by many scientists as a less toxic replacement for farm chemicals proven to be far more dangerous to humans and the environment is actually a killer in its own right. "We demonstrated that neonicotinoids are highly likely to be responsible for triggering Colony Collapse Disorder in bee hives," claimed Lu. The future of our food system and public health, he said, hangs in the balance. Read more

Colony Collapse Disorder exacerbated by stressed-out bees

Though no one cause has been identified for CCD, poor diets, exposure to pesticides and parasites are all on the list of potential causes. Now, the University of London says, pressure on young bees could also be a factor. Read more

The first comprehensive survey of CCD-affected bee populations

The first comprehensive survey of CCD-affected bee populations that suggests CCD involves an interaction between pathogens and other stress factors. We present evidence that this condition is contagious or the result of exposure to a common risk factor. Potentially important areas for future hypothesis-driven research, including the possible legacy effect of mite parasitism and the role of honey bee resistance to pesticides, are highlighted.

EU bans three pesticides belonging to the neonicotinoid family for a period of two years

The European Commission has adopted a proposal to restrict the use of three pesticides belonging to the neonicotinoid family (clothianidin, imidacloprid and thiametoxam) for a period of two years.

The Commission's action was in response to the European Food Safety Authority's (EFSA) scientific report, which identified "high acute risks" for bees as regards exposure to dust in several crops such as corn, cereals and sunflowers, to residues in pollen and nectar in crops like oilseed rape and sunflower and to guttation in corn.

In the US, the EPA is not currently banning or severely restricting the use of the neonicotinoid pesticides. The neonicotinoid pesticides are currently being re-evaluated through registration review.

Health Canada pushed to force pesticide makers to release bee-death studies

Four major environmental groups are demanding that Ottawa force pesticide makers to provide scientific studies looking at whether their products are killing off bees.

Health Canada's Pest Management Regulatory Agency has been asking registered pesticide manufacturers for the studies since 2004.

But despite several notices, the studies haven't been produced, while the pesticides in question continue to be manufactured and sold.

Graham White's Presentation on the Effect of Insecticides on Bees

An excellent presentation by Graham White, which covers the effect of neonicotinoids on bees.

Method, apparatus and compositions for the prophylaxis and treatment of colony collapse disorder

This invention concerns a method for preventing and treating Colony Collapse Disorder, consisting in the use of an automated device that delivers a diet specifically calibrated for consumption by farm colonies of bees to be treated. The apparatus comprises a box-like container accommodating in its interior at least one reservoir for liquid-tight, accessible from outside through a nozzle, an atomizing device of a liquid solution or suspension contained in the reservoir, means for the delivery of the liquid atomized solution or suspension into micrometric drops outside the apparatus, and a control unit programmed for timing the delivery of the solution or suspension to the outside, for the determination of the quantity of solution or suspension delivered and for emitting alarm signals in case of malfunction, the apparatus being powered DC with the energy supplied by a solar panel located outside of the container. The liquid solution or suspension comprises tonic and nutrient ingredients, mainly consisting of milk powder, sugars and lower organic acids, antioxidant and antiseptic ingredients contained in plant extracts and healing ingredients to bees, such as essential oils of thyme and oxalic acid.

Bee afraid, bee very afraid - Neonicotinoids and the nAChRs family

The reasons for the decline are currently not clear. However, some studies have linked the reduction in bee numbers to a widely-used class of pesticides, neonicotinoids, that have been broadly administered in large-scale crop production since the mid 1990’s – the same time that mass bee disappearances started to be reported 2. These nicotine-like chemicals, which include three key neonicotinoids: thiamethoxam 3, clothianidin 4,5 and imidacloprid 6,7,8, are considered safe for mammals, but are highly toxic to insects.

Methods for controlling Varroa mites

The present invention relates to methods and compositions comprising cyromazine for the control of bee mites and for the reduction of bee mite infestations, such as the control and reduction of infestations of parasitic bee mites, such as Varroa destructor in bee, preferably honey bee, colonies, and to the treatment of varroatosis in bees.
