[Responses of biological markers of larval Propsilocerus akamusi to phenol].

Taking the 4th-instar larval Propsilocerus akamusi as test object, this paper studied the acute toxicity of phenol, and the body mass, pupation rate, protective enzyme activities, and detoxifying enzyme activities of the larvae under exposure to phenol. The LC50 value of phenol to the larvae after exposure for 6, 24, 48, 72, and 96 h was 222.52, 134.
