Abstract
Third larval instar of Culex pipiens were
exposed to sub-lethal concentration LC25 of Black and White liquors
(waste extract from rice straw) for 24 hours to study its effect on some
enzymes activity along different developmental stages of mosquito.Acetylcholinesterase
(AchE) enzyme showed high activity in all stages
of mosquito treated in the larval stage with black and white liquors. Treatment with black
and white liquors showed lower in enzyme activity of esterases (a-est, β-est) and Glutathione s-transferase (GST). While, mixed function oxidase (MFO) enzyme showed high activity in all developmental
stages of C. pipiens larval treatment with black and white liquors in
comparing with control except in pupal stage low activity and not affected, respectively
