[Structural changes in the gypsy moth (Ocneria dispar L.) hemogram in polyhedrosis].

Structural changes in hemogram of Gypsy moth larvae from a population in the phase of quantity increase are studied morphometrically and cytochemically. The counts of granulocytes and prohemocytes are increased, as are the counts of hemocytes possessing phenol oxidase activity and hemocytes reducing nitroblue tetrazolium. Atypical virus morphogenesis is observed.
