- Abstract
The article presents the results of a study which investigated the impact of low doses of the pesticides endosulfan, carbaryl and atrazine on acetylcholinesterase (AChE) activity and fluctuating asymmetry (FA) in the larvae of Coenagrion puella, also known as the damselfly. The impact on traits such as growth rate, body size and mortality was also studied. Larvae exposed to the pesticides averaged longer development times. AChE activity was stimulated by carbaryl, diminished by atrazine and unaffected by endosulfan. No reaction to FA was produced by atrazine or carbaryl, but increasing endosulfan concentrations decreased FA. In general, FA was traded off with size while AChE inhibition correlated with increased mortality.
