Abstract

As a result of years of research considered alfalfa pollinator species composition agrocenosis and observed their effects on seed performance in Right-bank Forest Steppe of Ukraine. Found that entomokompleks insects that pollinate alfalfa consists of 16 species, but numerically dominate 5—8 species. Studied their daily activity, which has two peaks. Proved that reserve of natural pollinators of alfalfa is enough to implement biological yield potential of varieties at 800 kg/ha.
