Abstract The role of two mite species (Oribatida) in biological control of Rhizoctonia solani damping off and root rot diseases in cotton Oribatid mites (Acari: Oribatida) are considered to be the most diverse and species richness of soil micro-arthropods inhabiting most soils. Soil oribatid mites have a great importance in improving the soil structure; that by, motivating soil fertility, regulating decomposition rate, affecting nutrient cycling, and controlling soil pathogens. On the other hand, the soil inhabiting fungus Rhizoctonia solani is plant pathogen causing sever disease symptoms and crop losses in many agriculture host plants around the world. The present study was attempted to deal with the pathogenic fungus R.solani as a nutritional regime for different genera of soil mites under laboratory conditions and if tested soil mites would utilize R. solani as a food resource. Understanding of the nutritional relationship between R.solani and soil inhabiting mites is a crucial issue for the development of agricultural and horticultural growing systems that enhance plant health and influence on plant pathogens through a biological control method concerned suppression of disease symptoms in field situations. Therefore, that encourages a close interdisciplinary cooperation between soil zoologists, soil microbiologists, and agriculturalist to perform a good integrated pest management. |
