Abstract
The A.A. refer a recent experience about the isolation and identification of same species of storaged timber mites. They believe that these mites are responsible of dermatitis at the trunk and the arms of timber workers. Mites are the most elderly living species on the earth, they can live and grow in different environments, such as plants, flowers, animals, men, earth, lake and sea waters, organical rubles, houses, mattresses, old books etc. There are free-living, saprophitic, parasitic and predator mites. Generally, primary mites live either freely or as commensals feeding on conserved foodstuff and on what they find available. Secondary mites, i.e. parasites and predators, live off primary mites and insects infesting foodstuff. Direct damage to foodstuff are not to be considered important, whereas indirect damages are more serious, due to the contamination of bodies and stools of mites that are rich in nitrogen. Some secondary mites may attack foodstuff workers causing characteristic dermatitis: they can act either directly, by sting and bites, or indirectly, provoking on allergic hypersensitivity. In this study the A.A. used the floating method to isolate timber mites, and then, these have been photographed at the microscop...Continue Reading
