Abstract:

Food consumption by a Colorado beetle population on a potato field depends on the intensity of natural reduction; under the conditions prevailing in the optimum zone of occurrence of this species in Poland it forms 16-17% of potential consumption. Consumption does not appear to depend on density but on the initial number of eggs and can be defined as the simple function Cr = 0.18 No kcal. There is no serious threat to potato crops until the number of eggs laid exceeds 800 eggs/m2.
