Very least amount of Copper is recognized as a constituent of living system. Detection and estimation of Copper in various living systems have been done and reported by various workers time to time. The presence of Copper is reported more or less in all forms of life. The reported data of work done so far details are available everywhere. This review work is concentrated on its significance of the presence of optimum amount of Copper in living systems. The required particular amount of copper in physiological cycle results thriving, whereas the deviated amount of copper leads to menace in living system, this deviation from the optimum amount makes unhealthy and creates an abnormal condition of metabolic activities in the living systems. This work is totally based on the reports examined the effect of Copper on cellular cycle till today.展开更多

For this purpose, 40% and 80% of 24 hrs of LD50 values of various formulations were provided for treatment of termite workers. Observations were taken at 4 hrs time interval up to 16 hrs to know inhibitory activity of these combinatorial mixtures on termite species Odontotermes obesus. Significant (p > 0.05) alterations were observed in the level above mentioned bio-molecules when termites were treated with different combinatorial essential oils ingredients of Citrus maxima. Combinatorial mixtures of Tagetes erecta essential oils have shown synergistic activity against termites. This study will provide an overall sustainable way to termite control in crop field, gardens and houses. It also suggests use of essential oils as better alternative of synthetic termiticides as these are safer for environmental and human health.展开更多

In present investigation, various bio-molecules i.e. glycogen, protein, amino acid, DNA, RNA and lipid were evaluated to determine the anti-termite efficacy of Citrus maxima essential oil based combinatorial formulations against Indian white termite Odontotermes obesus. For this purpose, termites were treated topically with 40% and 80% of 24 hr LD<sub>50</sub> values of various combinatorial formulations. A significant (p > 0.05) alteration was noted in all the above biomolecules at various time intervals. Both dose response and time period was found important in physiological alteration in levels of various bio-molecules. Combinatorial mixtures of Citrus essential oils have shown synergistic activity against termites. The research outcomes of present investigation would help to open sustainable way to termite control in crop field, gardens and houses.展开更多
