CHANGE OF STRUCTURAL VARIETY OF HEMIPTERCOMPLEX (HEMIPTERA, HETEROPTERA) IN AGRICULTURAL SYSTEMS UPON ARABLE DIGRESSION ^{[№ 11 ' 2008]}
The work shows that under man\s impact, namely upon arable digression, variety of life forms, in particular diversity of hemipterofauna species, sharply decreases. The most depleted are life forms of hemipterous fauna on the last stages of arable digression. The most vulnerable to different types of impact are phytophages geobionts, herpetobionts and epigeobionts. On the whole, the strongest alterations upon arable digression might be observed with systematic groups of insects which live or reproduce themselves in soil. These changes affect not only faunistic composition of insects, but the number of certain species that in turn can make some species of insects the plant pests.
