UNA LISTA COMENTADA DE LOS SPHINGIDAE DE BOLIVIA (INSECTA: LEPIDOPTERA)
2001
An annotated checklist of the Sphingidae (hawkmoths) of Bolivia is presented. A total of 189 species and subspecies are confirmed. Locality data derived from specimens in the collections of the Department of Entomology of the Natural History Museum Noel Kempff Mercado of Santa Cruz de la Sierra; the Bolivian Collection of Fauna, La Paz; The Natural History Museum, London; and the Carnegie Museum of Natural History, Pittsburgh, are given. A map of these localities and a synoptic discussion of their geography and ecology are also provided. Data on species not represented in these collections are collated from the publications of J. Haxaire and D. Herbin and presented. Diagnostic features to e…
Hypoxia and anoxia in insects: microcalorimetric studies on two species (Locusta migratoria and Manduca sexta) showing different degrees of anoxia to…
1995
Abstract Microcalorimetry was used to study the effects of graded hypoxia and anoxia on two species of insects that differ in their tolerance of anoxia. Locusts (Locusta migratoria) can survive an atmosphere of pure nitrogen for not more than 4 h (at room temperature), whereas hawk moths (Manduca sexta) can recover from more than 24 h of anoxia. To produce graded hypoxia, air and pure nitrogen were mixed and this mixture was passed through the cells of a twin calorimeter equipped with circulation cells. A gas flow containing 2% or more of oxygen had no significant effect on behaviour (as observed in parallel experiments using transparent cells) or heat flow rate. If oxygen content was reduc…
