In: Alexandria Science Exchange Journal 2008.v.29(3)Summary: The effect of three insecticides; methomyl (carbamate), dimethoate and malathion(organophosphates) and one cupper-containing fungicide (Cupper hydroxide) was evaluated in vivo on acetylcolinesterease (AChE) isolated from earthworm Lumbricus feTrestirs to achieve a better understanding of AChE responses to agrochemicals in L. terrestirs. Three values of median lethal concentrations of the four compounds were determined from the acute toxicity (0.1, 0.5 of LC50 and the LC50). The three insecticides at the three levels of LC50 inhibited AChE activity and the inhibition was dose dependent.
