As a result of our researches on the fauna of the strawberry and the raspberry which took place in the period 1999-2002, started the overall examination of the fauna in the bigger industrial strawberry and raspberry plantations, grown in the most typical regions of the country. We determined the content of species and the quantity of the harmful, useful and the neutral fauna(insects, mites, spiders, nematodes and other kinds of animal otganisms) as well in the vegetation period as in the period of rest of plants. We expose the results for their number, the distribution by classes, families and gender in tables to obtain more clearness.
