BIOSYSTEMATICS OF THE GENUS EUXOA (LEPIDOPTERA: NOCTUIDAE): III. HEMOCYTOLOGICAL DISTINCTIONS BETWEEN TWO CLOSELY RELATED SPECIES, E. CAMPESTRIS AND E. DECLARATA

Abstract

AbstractThe shape of one single category of hemocytes served as a critically distinguishing character between larvae of two closely related species of Euxoa (Lepidoptera: Noctuidae) that were otherwise practically identical in external features. The ratio of length/width of fusiform plasmatocytes in heat-fixed blood films was significantly smaller in larvae of E. campestris (Grote) than in E. declarata (Walker).
