Pesticides neurotoxicity

It is very clear, therefore, that there have been many examples of neurotoxic effects, both lethal and sublethal, caused by pesticides in the field over a long period of time. Far less clear, despite certain well-documented cases, is to what extent these effects, especially sublethal ones, have had consequent effects at the population level and above. Interest in this question remains because neurotoxic pesticides such as pyre-throids, neonicotinoids, OPs, and carbamates continue to be used, and questions continue to be asked about their side effects, for example, on fish (Sandahl et al. 2005), and on bees and other beneficial insects (see, for example, Barnett et al. 2007). 

Many of these tests gave evidence for changes in behavior following exposure to neurotoxic pesticides. The author concludes that significant behavioral effects were often recorded down to one order of magnitude below the LCjo in question. Some tests, such as operant tests, were relatively simple and gave reproducible results, but it was difficult to evaluate the relevance of these to survival in the wild. Other tests, such as breeding behavior and prey capture, were more complex and less reproducible, but more relevant to the natural world.
