Resistance to Starvation of Triatoma rubrofasciata (De Geer, 1773) under Laboratory Conditions (Hemiptera: Reduviidae: Triatominae)

The present work aims at learning the period of resistance to starvation (molting/death) of Triatoma rubrofasciata in different stages of development and the respective loss of weight until death. Eggs of specimens from the greater area of the city of São Luis in the State of Maranhão, Brazil, yielded approximately 300 nymphs. These nymphs were placed in labelled Borrel glasses, in which they were weekly fed on rats (Rattus norvegicus), until reaching the stage to be observed. The experiments were conducted in a climatic chamber regulated at 29 ± 1° C, 70% relative humidity and 12 hr photoperiod. The resistance to starvation increased according to the stage of development, except for adult bugs, whose results were similar to the 3rd stage nymphs. In all these development stages there was an abrupt loss of weight in the first week, followed by a gradual loss until death. Comparing this work with those of other authors, it was observed that T. rubrofasciata is among the less resistant triatomine species.

Incidence of myiasis in Panama during the eradication of Cochliomyia hominivorax (Coquerel 1858, Diptera: Calliphoridae) (2002-2005)

We present the results of a study on myiasis in Panama during the first years of a Cochliomyia hominivorax eradication program (1998-2005), with the aim of investigating the behavior of the flies that produce myiasis in animals and human beings. The hosts that registered positive for myiasis were cattle (46.4%), dogs (15.3%), humans (14.7%), birds (12%), pigs (6%), horses (4%), and sheep (1%). Six fly species caused myiasis: Dermatobia hominis (58%), Phaenicia spp. (20%), Cochliomyia macellaria (19%), Chrysomya rufifacies (0.4%), and maggots of unidentified species belonging to the Sarcophagidae (3%) and Muscidae (0.3%). With the Dubois index, was no evidence that the absence of C. hominivorax allowed an increase in the cases of facultative myiasis.

Filmar la historia a partir de Peter Weiss

La lectura de La estética de la resistencia nos permite detectar una serie de operaciones que, durante el proceso de escritura, Peter Weiss pone en marcha y queencontraremos reflejadas a su vez en algunos cineastas contemporáneos en la aproximación al tratamiento de la Historia. La novela nos da pie a intentar sacar a la luz sus costuras: el entrecruzamiento de temporalidades como forma de hacer saltarel presente; la recuperación del archivo personal que permitirá el tratamiento de laHistoria en primera persona; la evolución desde la incorporación del registro enbruto a la escenificación de las discusiones entre partes; la descripción exhaustiva deacontecimientos y obras de arte y su continua puesta en relación con la vidacotidiana de los personajes, que configurará lo que Fredric Jameson entiende comouna “pedagogía del subalterno” y que coincide plenamente con la “emancipaciónintelectual” que propone Jacques Rancière.
