Recurrence of mass reproduction of sugar beet pests has
been studied. Investigations proved that mass reproduction
of sugar beet pests was observed cyclically rather
than periodically. Synchronism of population cycles with
sudden changes of of solar activity has been snown. Solar
activity is recommended to use for prediction of the
beginning of next mass reproduction.
