Malathion is a vital agent and indicator that kills targeted (harmful) organic of flora and fauna. Word ‘pest’ has comprised of detrimental animals, plants and microorganisms. These are widely used all over the world in agriculture. several agricultural pesticides nowadays in the trend in which organisms toxicity and harmful alterations are noticeable. Malathion pesticides used as agricultural benefits for crop production. This type of pesticide mostly affects the histological and biochemical parameters of the organism. This study focuses on alterations of malathion observing special site tissues of freshwater fish Clarias batrachus (Linn.,1758). Malathion (50% EC) was ordered from super ford insecticides limited, Sikandrabad (BSR) and a volumetric practical performed to result out the LC50 96 hours of malathion. Value of malathion LC50 96 hours calculated 0.25 ppm. The SLC as 0.025 parts per million was fixed by using 1/10th of LC50 at 96 hours [1]. The effect of malathion SLC (1/10 of 96 hours of LC50) was investigated on the histology of the liver in treated groups of host fish. Specific changes were checked in liver histology using control and treated groups. Histological observations as hepatocytes degeneration, Necrosis in hepatocytes, vacuolar degeneration, congestion were recorded and analyses as per experimental requirement. The main objective of this article is to carry out a histological study to check the impacts of the Sublethal concentration of Malathion (EC50%) on the liver of “Clarias batrachus.”

Objective: The objective of the present study is the evaluation of the effect of the sublethal (40% and 60% of 48h LC50) binary combination (1:5 ratios) of molluscicides deltamethrin+MGK-264 on the endogenous levels of protein, amino acid and nucleic acid in different tissues of snail Lymnaea acuminata. Methods: The snails were treated with 1:5 mixtures of sub-lethal concentration of (40% and 60% of 48h LC50) deltamethrin+MGK-264 on the protein, amino acid and nucleic acid levels in gonadal, nervous and foot tissue of L. acuminata. In order to study the effect of withdrawal from treatment, the snails were first exposed to the above concentrations for 96h, after which they were transferred to freshwater. Water was changed every 24h for the next seven days, after which different biochemical parameters were estimated. Results: There was a significant change in the levels of protein (sublethal concentration of 60% of 48h LC50 after 96h) gonadal, nervous and foot tissues are 48.1, 12.1 and 14.5%, respectively, amino acid are 273, 234 and 252%, respectively, DNA are 25.1, 38.9 and 42.1%, respectively and RNA are 12.2, 30.7 and 30.5%, respectively. These changes were time and concentration-dependent. In the withdrawal experiment, the snails were treated for 96h to transfer in freshwater for 7 d, which caused significant recovery in all the biochemical parameters. Conclusion: The present study concluded that the high molluscicidal activity of deltamethrin+MGK-264 simultaneous decrease in the levels of proteins, DNA, RNA and increase in the level of amino acids.
