The work has been conducted to study staying possibility and maintenance of Egyptian subterranean termite Anacanthotermes ochraceus and Ametermes desertorum, under laboratory conditions for research purposes under constant and variable temperatures (thermo-rhythm), in addition to study the termite susceptibility variable under the tested temperatures degrees. Data obtained revealed that, the constant temperature 25C° was the most favorable for termite survival and food consumption, followed by the temperature 30C°, but, when using of variable temperatures (thermo-rhythm), data obtained showed that, the temperature 25-30C° were the most favorable relatively for termite activities (termite life and food consumption). Under conditions, the constant temperature 25C° and the variable temperature 25-30C°, survival and food consumption recorded highly rates and the examined termites were lived more than 6th week. In addition to, the survival rates for all treatments were decreased gradually from 1st week to 6th week and vice versa, in case consumption rates. in comparison between the two tested subterranean termites, data showed that, the termite A. ochraceus, was the highly endurance, more than, A. desertorum, for life activities under the examined conditions. Throughout the data the using of thermo-rhythm around 25-30C° are the favorable condition for termite when the staying and maintenance of termite are desired.
