title: Sensitivity of Daphnia carinata sensu lato to the insect growth regulator, pyriproxyfen.
abstract: This paper reports the sensitivity of Daphnia carinata sensu lato to pyriproxyfen, a promising chironomid control agent. Neonates exposed to pyriproxyfen in acute toxicity trials produced 48-hr LC50 of 0.08 ppm, eight times the concentration known to control the emergence of nuisance chironomids. However, continuous exposure to pyriproxyfen (0.01 ppm) during a 3-brood, 14-day life cycle test, suppressed the growth of D.carinata and reduced reproduction by as much as 80%.
