چکیده
Microcerotermes diversus Silvesteri is the most destructive termite pest among subterranean termites in tropical and subtropical regions, including Khuzestan province, southwest Iran, feeding on wood products used in residential areas and structures. Use of large amounts of pesticide to combat this pest has harmful effects on the environment. In previous studies, sublethal concentrations of some pesticides caused biochemical and physiological disturbances in the storage of carbohydrates, lipids and proteins. Imidacloprid, a neonicotinoid, affects postsynaptic acetylcholine receptors. Pesticides that disrupt the nervous system, stimulate or inhibit enzyme activity, or induce or reduce the synthesis of enzymes, can decrease or increase termite energy reserves. In this study, we studied the in vitro effects of imidacloprid concentrations of 5, 10, 25 and 50 ppm on the reserves of lipid, carbohydrate and protein in termite workers. Imidacloprid induced a significant effect on the amount of protein, lipid, sugar and glycogen energy in treated termites. The concentration of 50 ppm had the greatest effect on energy sources with decreases in the amount of protein by 39.58%, lipid 51.93%, glycogen 63.73%, sugar 58.59% and energy content 59.93% compared to the controls.
