Morphometric variations in the grasshopper, Chromacris speciosa from two localities of Pernambuco in northeastern Brazil.

Abstract The present study describes morphometric variations in the grasshopper, Chromacris speciosa (Thunberg, 1824) (Orthoptera: Acridoidea: Romaleidae) from two locations in the state of Pernambuco, Brazil. The distance between the sites chosen for collections (Recife and São Lourenço da Mata) is approximately 16 km. The investigation was based on a comparative study of external morphological characteristics of the grasshoppers.

Metabolism by grasshoppers of volatile chemical constituents from Mangifera indica and Solanum paniculatum leaves.

The chemical volatiles from plant leaves and their biological activities have been extensively studied. However, no studies have addressed plant-chemical volatiles after undergoing the digestive process in host insects. Here we describe for the first time chemical profiles of volatile constituents from Solanum paniculatum and Mangifera indica leaves metabolized by grasshoppers.

[From animal medical practitioners to veterinarians: historical note on animal medicine and the São Bento de Olinda Graduate School of Veterinary Medicine, Pernambuco (1912-1926)].

The historical aspects of animal medicine indicate an epistemological break with the old practices of animal medical treatment, with introduction of the principles of rationality in the eighteenth century in the formation of veterinary doctors. These healing practices, meanwhile, did not begin with the implementation of graduate courses in animal medicine. In colonial Brazil and, in particular, in the State of Pernambuco, historical records can be found of animal medical practices that were later incorporated into the curriculum of the São Bento de Olinda Graduate School of Veterinary, marked by the presence of a unique evaluation in Brazil: the physicum examination.
