ANDRADE-HERRERA, K.; RUIZ-GONZALEZ, C.  y  CORDOVA-ESPINOZA, M.. Comparative study of insects associated with guinea pig corpses in two forms of death in Castilla, Piura (Perú). Cuad. med. forense [online]. 2018, vol.24, n.1-2, pp.6-13.  Epub 21-Sep-2020. ISSN 1988-611X.

The insects associated with corpses of guinea pigs were determined, in the two forms of death with the highest incidence in Piura: poisoning (rat poison) and white weapon (knife); using as a witness, a death due to cardiorespiratory arrest. For this purpose, female guinea pigs, of similar weights and from the same farm, were slaughtered in three repetitions (one per month), exposed in an area of dry forest in the district of Castilla, in metal mesh cages, and separated 60 meters between them. The collection of adult diptera was carried out with an entomological network, and the sacrifice of these, in a deadly vial with cyanide. Coleoptera were collected by manual sampling around the body, and sacrificed in a deadly vial with 70% alcohol.

All individuals were determined and quantified with a stereoscope and taxonomic keys, always trying to reach the lowest taxonomic level. The SPSS program Vs.22 was used to calculate the differences in the entomofauna between the forms of death, through the analysis of variances (ANOVA). There were a total of 24 species, corresponding to 22 species for the control, 17 for poisoning and 19 for weaponry, at an average temperature and humidity of 25.94 °C and 63.19% respectively, there being no statistically significant differences between the forms of death at a significance level of 0.05.
