States Must Adopt EU Pesticide Regulations to Stop Insect Extinction

The world is in the midst of an insect extinction crisis.  We've all heard about the plight of bees, but the plight of all insect fauna is much less widely appreciated.  The figure below is from a report in Science  a few years ago showing the precipitous decline in insects worldwide.[1] What beekeepers and naturalists [...]

Threshold mechanisms in acetylcholine pathway insecticides and environmental safety

Overview Previously we looked at some of the basic principles of nervous system function and how chemicals from several pesticide classes disrupt normal function.  This time we will look in detail about what we can expect for a dose-response characterization of acetylcholine pathway insecticides based upon their mode of action and properties of the nervous system. [...]

Blog post gets Published!

What started out as a bit of curiosity about the time-dependent toxicity of insecticides led to a blog piece I did a little over a year ago titled Time-dependent Toxicity of Imidacloprid in Bees and Ants.  I thought my results were interesting enough to get a comment from other scientists that were looking at the time-dependent [...]

The Mechanisms of Neuro-toxic Pesticides

Agricultural pesticides have become part of the chemical landscape that we all  live in.  To be able to make intelligent decision about the use and regulation of these chemicals, it's important to understand how they work.  Almost all modern pesticides are chemicals that interfere in some way with the nervous system. The characteristics of the [...]

Environmental Implications of Pesticides with Delayed Toxicity

The debate about the environmental safety, or lack there of, for the neonicotinoid insecticides begs us to ask what would be the characteristics of an environmentally safe or benign pesticide?  Despite a growing and flourishing organic agriculture movement, industrial agriculture is not going away any time soon.  Hence it is important to understand how to [...]

Neonics and Bees — Political Inaction Persists Despite Mounting Evidence

Over the course of the last year, the issue of bees and the neonicotinoid pesticides has finally begun to appear in the popular press in this country.  A campaign by Friends of the Earth in the UK resulted in major garden center chains removing the neonics from their shelves in February of last year.  Early [...]
