Atrazine exposure increases time until cannibalistic response in the widow skimmer dragonfly (Libellula luctuosa)

Canadian Journal of Zoology, Volume 0, Issue 0, Page 113-117, e-First articles.

Agricultural runoff containing herbicide is known to have adverse effects on freshwater organisms. Aquatic insects are particularly susceptible, and herbicide runoff has the potential to affect behavior in this group. Here we examine the effects of short-term exposure to the herbicide atrazine on cannibalistic behavior in larvae of the widow skimmer dragonfly (Libellula luctuosa Burmeister, 1839). Large larvae (>12 mm length) were exposed to concentrations of 0, 1, 10, or 100 μg/L atrazine for 96 h. A smaller (
