 abstract={The joint effect of the whole phytophagous invertebrate fauna on the amount of biomass produced by vascular plants was investigated in two meadow associations: Stellario-Deschampsietum, ord. Molinietalia, and Arrhenatheretum elatioris, ord. Arrhenatheretalia. In a field experiment the crop of plants in areas from which insects had been eliminated (by insecticides) was compared with the crop of plants infested by insects. The presence of this fauna resulted in a noticeably lower growth rate of plants; the maximum of biomass was retarded, and consequently the crop was lower.},
