Effect of Controlled Temperature on Biological Cycle of Cochliomyia Macellaria Fabricius, 1775; Chrysomya Rufifacies Macquart, 1843 Y Phaenicia Eximia Wiedemann, 1819 (Diptera: Calliphoridae)

Abstract

Cochliomyia macellaria Fabricius, 1775; Chrysomya rufifacies Macquart, 1843 y Phaenicia eximia Wiedemann, 1819, they belong to the family Calliphoridae and they are considered by the international scientific community of criminalistic interest; because they are frequent in most of the states of decomposition of a carcass. The studies on the taxonomy and influence of climatological factors in the development of immature stadiums of blowflies, it is an investigative slope without precedents in the Cuba. The insufficient ones relating on this faune in particular, they impede the use of these species to determine the interval postmortem in the Cuban Criminalistic. The objective of this investigation was to evaluate the influence of the temperature under controlled conditions of laboratory to (30° C and 70-90 % of relative humidity), in the duration of the biological cycle of these species. The adult blowflies was gathered by means of the jameo technique and they were identified by means of key dichotomous of group in Neotropic. The morphological characteristics of the immature stadiums observed under the optic microscope were described and cultured for later on to be identified. They are presented curved of larval growth for each one of those selected. The morphology of the immature stadiums allowed it facilitated in a correct way its identification taxonómica, as well as the determination of the transition of its larval stadiums. This study is the first one carried out with Calliphoridae. The obtained results enrich the taxonomy on this family of insects; strengthens the knowledge of these in support to their practical utility and it constitutes an alternative and novel tool for the estimate of the interval postmortem.
