@paulpeace Unfortunately, to discover this, healthy bees were treated with the pesticides and then underwent several procedures (not sure whether any bees survived).
At least, the research was done for the benefit of the species. Although, indirectly it was of course done for the benefit of humans, because we need bees to pollinate our food.

Research on insects is not subject to animal ethics committee approval.
Honeybees use wide-field visual motion information to calculate the distance they have flown from the hive, and this information is communicated to conspecifics during the waggle dance. Seed treatment insecticides, including neonicotinoids and novel insecticides like sulfoxaflor, display detrimental effects on wild and managed bees, even when present at sublethal quantities. These effects include deficits in flight navigation and homing ability, and decreased survival of exposed worker bees. Neonicotinoid insecticides disrupt visual motion detection in the locust, resulting in impaired escape behaviors, but it had not previously been shown whether seed treatment insecticides disrupt wide-field motion detection in the honeybee. Here, we show that sublethal exposure to two commonly used insecticides, imidacloprid (a neonicotinoid) and sulfoxaflor, results in impaired optomotor behavior in the honeybee. This behavioral effect correlates with altered stress and detoxification gene expression in the brain. Exposure to sulfoxaflor led to sparse increases in neuronal apoptosis, localized primarily in the optic lobes, however there was no effect of imidacloprid. We propose that exposure to cholinergic insecticides disrupts the honeybee’s ability to accurately encode wide-field visual motion, resulting in impaired optomotor behaviors. These findings provide a novel explanation for previously described effects of neonicotinoid insecticides on navigation and link these effects to sul...
@[email protected] I don't want to get complacent but I feel this country is finally safe for a long time ahead!
Twitter may be about to fold but here in Australia it it has been now a huge factor in keeping the hard right out in two Australian elections now
The next challenge is take on media
Government owned utilities and services. How I miss thee.
Just imagine if we’d nationalised all our natural resources. What lost opportunity. Imagine no Gina Rinehart.
Why do Australians accept mediocrity? We could be the best in the world at so many things.
