Collembola, an important group of soil Microarthropods are usually associated with moist habitats, However, some species show an adaptation to ecosystems subject to periodic desiccation. This study examined population structure of collembola communities in its native natural site at Firozabad Soil apterygotes were dominated by collembolans belonging to the families, Isotomidae and Entomobryoidae. The highest density was of Entomobryoidae found during rainy season followed by Isotomidae. However the least population was that of Poduridae and Tomoceridae. The present study establishes a direct effect of high atmospheric temperature and low soil moisture on the population density of these microarthropods and this population is also affected by the soil management practices. These soil microarthropods especially collembola are of great significance for the health of the soil and its fertility. The details have been discussed in this paper.
