title: Morphometry of the midgut epithelium of Diatraea saccharalis Fabricius, 1794 (Lepidoptera) parasitized by Cotesia flavipes Cameron, 1891 (Hymenoptera).
abstract: The morphometric study of the midgut in Diatraea saccharalis (Lepidoptera) larvae parasitized by the Cotesia flavipes (Hymenoptera) showed that there was significant increase in the columnar, goblet and regenerative cells and their nuclei; the midgut lumen diameter and the epithelial height were also increased in the parasitized larvae. The multivariate analysis showed that parasitism affected the columnar cell only in the posterior region, and the goblet cells along the midgut length (anterior and posterior regions).
