“…Jales et al, analizaron la presencia de organofosforados en restos cadavéricos, observando que, a mayor dosis, se produjo la descomposición cadavérica con mayor rapidez en las primeras 24 horas, se redujo el número de insectos que aparecieron en el cadáver, hubo cambios en el patrón de sucesión, y demoró la llegada de especies importantes para la determinación del IPM; además, se vio un incremento en la mortalidad de las especies (38).…”

Resumen Introducción: la entomotoxicología se enfoca en la aplicación del análisis toxicológico a los insectos que se encuentran en los cadáveres, para identificar la presencia de drogas y toxinas en los tejidos o restos cadavéricos. Objetivo: realizar una revisión sobre la utilidad de la entomotoxicología como herramienta para las Ciencias Forenses, en cadáveres que se encuentran en estado de descomposición avanzada, cuando no es factible la recolección de muestras biológicas. Materiales y métodos: se realizó una búsqueda en Pubmed, Scopus, Scielo y Google Académico con las palabras clave: Forensic entomology / entomología forense, Forensic entomotoxicology / entomotoxicología forense, Criminology / criminología, Forensic toxicology / toxicología forense, Poisoning / envenenamiento y Postmortem interval determination / determinación del intervalo postmortem. Se incluyeron publicaciones de acceso libre, en español e inglés; publicados desde 1992 hasta marzo 2021. Resultados: la búsqueda inicial arrojó 3476 referencias (Pubmed: 50; Scopus: 402; Scielo: 114; Google académico: 2910). Quinientas sesenta y seis publicaciones fueron excluidas por duplicación; 49 fueron incluidas en esta revisión. Conclusiones: los insectos permiten un análisis fiable de toxinas y drogas cuando no es posible realizarlo directamente desde los restos cadavéricos. En Ecuador, se requieren estudios que indaguen la aplicación y desarrollo de esta rama para determinar su precisión y utilidad a nivel local, provincial y regional. A nivel global, se debe expandir la investigación entomotoxicológica en escenarios acuáticos o de incendios; así como el impacto del cambio climático sobre la entomofauna y sus repercusiones en el análisis toxicológico de las distintas especies.

“…Therefore, insect colonization in carcasses decomposing with abiotic factors influence (e.g. temperature and moisture) and carcass conditions (e.g., completeness, toxicology, and pathology) may determine the decomposition rates in an ecosystem (Andrade-Herrera et al, 2020;Jales et al, 2020;Moretti et al, 2008;Von Hoermann et al, 2021).…”

“…The genus Mus was introduced in Brazil in the European colonization, and was the main representative the species Mus musculus that can inhabit both urban and rural areas (Feng & Himsworth, 2014). However, despite many studies in the tropical region (Cruz & Vasconcelos, 2006;Jales et al, 2020;Oliveira-Costa, 2013;Pujol-Luz et al, 2006), few studies were carried out in the Neotropical subtropical region on the survey of cadaveric fauna (Trivia & Carvalho, 2018).…”

We evaluated the insect succession in small rodent carcasses on the soil extracts (surface vs. buried) in two areas (riparian vs. agricultural) and two seasonal periods (spring vs. summer). Daily, the rodent carcasses were weighed and the insects present were collected in them for counting and family level identification. We also measured the air and soil temperature daily, in addition to the physical and chemical characteristics of the soil. The total of 11,059 individuals from 28 taxa was collected. The most abundant taxa were Calliphoridae (70%), Formicidae (20%), Muscidae (2%), and Sarcophagidae (2%). Insect richness was higher in spring in riparian vegetation areas; however, decomposition and insect abundance were greater in spring in agricultural areas by the high temperature measured. Vespidae, Sarcophagidae, Muscidae, and Calliphoridae decreased over time with abundance peaks respectively at 3, 7, 7, and 8 days in riparian vegetation areas. Calliphoridae decreased abundance over time with a peak at five days, but Armadillidiidae increased with peak at 6-9 days in agricultural areas. Decay and insect abundance was high in agricultural areas, mainly on the soil surface. Insect richness was high in riparian vegetation areas, especially on the soil surface. Only the superficial layers of soil presented taxon indicators and all decreased over time with abundance peaks of Calliphoridae, Sarcophagidae, and Muscidae at 5-8, 7, and 7 days, respectively. This abundance peak of insect families help to understand the degradative succession of the insect community in small rodents in subtropical systems of the neotropical region.

“…A careful examination of the collected material, patterns of entomological succession, and the rate at which insects develop can aid in determining the post-mortem interval (PMI), which is the time between death and the body's disclosure 2 3,4 . A careful examination of collected material, patterns of entomological succession, and the rate of development of insects can assist in determining the post-mortem interval (PMI), which is the shortest period of time between death and disclosure of the dead body [5][6][7] . Thus, forensic science is bene cial in determining the time of death, as well as in determining the location and cause of death, particularly when poisoning or drug overdose are suspected 8 .…”

Assessing the post-mortem interval (PMI) based on the growth and development of insects is a critical task in forensic entomology. The rate of larvae development can be affected by a variety of toxins, including pesticides. Aluminum phosphide (AlP) is a low-cost insecticide that has yet to be entomotoxicologically tested, despite the fact that it is frequently the cause of fatal poisoning. In this study, we measured the body length of Chrysomya albiceps larvae reared on the carcasses of rabbits poisoned with AlP and analyzed the morphological changes of the larvae reared on the carcasses of rabbits poisoned with AlP. The concentration of AlP in the body of the larvae was significantly lower than in rabbit tissues. Insects from the AlP group had a significantly lower gain in body length. Furthermore, deformities in the larvae were found. Small respiratory spiracles were found, as well as a deformed small posterior end with hypogenesis of the posterior respiratory spiracles. Thus, disturbed growth and development of carrion flies found at a crime scene could indicate pesticide poisoning, such as aluminum phosphide.
