Effects of 2,4-Dichlorophenol on the Net-Spinning Behavior of Hydropsyche slossonae Larvae (Trichoptera; Hydropsychidae), an Early Warning Signal of Chronic Toxicity
In order to assess the potential of hydropsychid capture net anomalies as a bioindicator of chronic toxicity in streams and rivers, the effects of 2,4-dichlorophenol (2,4-DCP) exposure on the net-spinning behavior of Hydropsyche slossonae were examined for anomalies after 0, 5, 10, 15, and 20 exposure days to gradient concentration of 2,4-dichlorophenol. The net-spinning behavior was significantly
