background: malathion (mal) is a choice insecticide in the stored grain in different countries. the aim of the present study is to evaluate toxicological effects of 30-day intake of mal on the male reproductive system of wistar rats. methods: this research was ethically approved by the local authority at faculty of medicine, monastir, tunisia. three mal treated groups received 1 ml corn oil con...
The specimens of Oreochromis niloticus were exposed to Malathion to determine the lethal concentration (LC50) value and effects of sub-lethal concentrations on haematological and biochemical parameters. The LC50 value was registered as 1.06 mg/l. Fishes exposed to sub-lethal concentrations (0.12, 0.23 and 0.46 mg/l) for 6 weeks revealed that the pesticide causes alterations in various blood par...
An investigation was carried out to evaluate the relative toxicity of selected newer insecticides viz., deltamethrin, spinosad, abamectin and emamectin benzoate in comparision with the organophosporus insecticide malathion to the maize weevil, Sitophilus zeamais Motschulsky, in an attempt to find out a safer and effective seed protectant. The LC50 values based on bioassay studies indicated that...
Background: Organophosphorus pesticides has been widely used in agriculture fields to control various crop insects and their extensive use pose human life at threat because of their adverse effects on human health. In this study, we checked the effects of GST polymorphism on ameliorative effect of curcumin and carvacrol against DNA damages. Methods: Comet assay was used to assess the DNA dam...
Abstract. Sayono, Nurullita U, Handoyo W, Tyasningrum WS, Chakim I, Budiharjo A. 2023. Bioassay and molecular detectionsof insecticides resistance of Aedes aegypti, vector dengue in Central Java Province, Indonesia. Biodiversitas 24: 300-307. The emergence insecticide-resistant strains among aegyptipopulations hampered Dengue control programs the endemic areas. Moreover, to understand current s...
Environmental exposures generally involve chemical mixtures instead of single chemicals. Statistical models such as the fixed-ratio ray design, wherein the mixing ratio (proportions) of the chemicals is fixed across increasing mixture doses, allows for the detection and characterization of interactions among the chemicals. In this study, we tested for interaction(s) in a mixture of five organop...
Background: German cockroach, Blattella Germanica, is a mechanical vector of various pathogenic agents such as viruses, bacteria, protozoa and parasite eggs. The purpose of this study was to determine the susceptibility level of German cockroach to bendicarb and carbaryl from carbamate insecticides, and malathion and chlropyrifos from organophosphorous insecticides. Methods: In this study, ...
Thermally treated egg shell materials were prepared at different temperatures. The samples were investigated by means of FT-IR and thermogravimetric analysis (TGA). The adsorption behaviour of malathion on egg shell and its thermally treated samples was studied using batch method and gave uptake capacities up to 0.964 mmol/g. Adsorption kinetics as well as the adsorption isotherms were discusse...
The effect of sub-lethal doses of Malathion and Methyl-Parathion was studied on the rat liver enzymes. Intravenous administration of both insecticides at weekly interval for four weeks resulted in increase in weight of various tissues, i.e., heart and spleen. Short term (24 hr) and long term (4 weeks) treatment with insecticides resulted in increased specific activities of liver enzymes, Acid p...
