ABSTRACT
Due to the lack of literature dealing with the histology of the heart in insects, specifically in Orthoptera, the present research was aimed at describing the histology of the heart of the Tropidacris collaris grasshopper (Stoll, 1813), which can be significantly harmful to cultivated plants and, for this reason, economically important from the agricultural point of view. The histology of this organ was carried out by means of light microscopy, with staining by Mallory’s trichrome and by hematoxilyn-eosin (H-E), at the Laboratory of Histology of the Department of Morphology and Animal Physiology of the Rural Federal University of Pernambuco (UFRPE). The insects were obtained from the insect rearing facilities of Laboratory of Entomology of the Department of Biology of UFRPE. The collected material was fixed in Boüin’s liquid and processed for inclusion in paraplast. The results revealed that the heart of T . collaris is constituted by a layer of muscular tissue, being covered internally by conjunctive tissue.
