The Government is being asked to investigate a possible link between a new generation of pesticides and the decline of honey bees. It is suspected that the chemicals may be impairing the insects' ability to defend themselves against harmful parasites through grooming.
The Environment Secretary, Caroline Spelman, will have to answer a question in the Commons from the former Home Office minister David Hanson about whether the Government will investigate if the effect of neonicotinoids on the grooming behaviour of bees is similar to its effect on termites.
The pesticides, neonicotinoids, made by the German agribusiness giant Bayer and rapidly spreading in use, are known to be fatal to termites by damaging their ability to groom themselves and thus remove the spores of harmful fungi.
In a leaflet promoting an anti-termite insecticide, Premise 200SC, sold in Asia, the company says it is the direct effect on the insects' grooming abilities of the neonicotinoid active ingredient, imidacloprid, which eventually kills them. Now bee campaigners in Britain want to know if this mechanism could also be at work on European honey bees and other pollinating insects which are rapidly declining in numbers.
