The objective of this study was to determine if Roundup (active ingredient: Glyphosate) causes negative effects on behavior, growth, and mortality of larval Pachydiplax longipennis. Larvae were captured from rainwater-filled mesocosms at Hancock Biological Station in Murray, KY. Larvae were exposed to one of four concentrations of Roundup (0mg/L, 2.5mg/L, 5mg/L, or 10mg/L). Daphnia consumption, seek refuge, and anti-predator trials were conducted at 7 and 14 days post-exposure. Growth and survival trials were carried out for eight weeks using different larvae. There were no significant differences among treatments for whether or not larvae ate offered Daphnia for Day 7 …
