Sublethal Concentrations

The effect of sublethal concentrations 1/8 and 1/4 of LC50 at 24 h of five pesticides including three organophosphates, Dimethoate, Malathion and Quinalphos, one neonicotinoid Acetamiprid and one biopesticide Neem oil on acetylcholinesterase (AChE) activity in forager bees of Apis mellifera was studied. The specific activities of acetylcholinesterase (AChE) were measured in head and thorax of surviving foragers after 24 h of treatment. The data revealed that all the pesticides suppressed the AChE activity but organophosphates had more inhibitory effect on AChE activity as compared to neonicotinoid Acetamiprid. Among organophosphates Dimethoate proved to be most toxic at sublethal concentrations followed by Malathion, Quinalphos and acetamiprid. Significant changes were observed at 1/4 of LC50 at 24 hrs but did not have so well defined inhibitory effect at 1/8 of LC50 at 24 h Neem oil was found to be nontoxic.

Effect of quinalphos on the freshwater fish, Cyprinus carpio to elucidate inhibitory effect of quinalphos on acetyl cholinesterase activity associated behavioral changes. Fishes were exposed to one fifth (0.15 ?g/l) and one tenth (0.75 ?g/l) of the lethal concentration (7.5 ?g/l) of quinalphos for a period of 1, 7 and 14 days, and were allowed to recover for 7 days. Maximum decrement in acetyl cholinesterase activity of the exposed fish was recorded in brain followed by muscle, gill and liver. Recovery tenures witnessed increment in acetyl cholinesterase activity but significantly differed in comparison with control group. Depression of acetyl cholinesterase activity suggests decreased cholinergic transmission and consequent accumulation of acetylcholine in the tissues leading to cessation of nerve impulses. This has lead to behavioral and morphological changes due to impaired neurophysiology of the fish. .
