Resumo
A Entomologia Forense é uma ciência que tem como base o uso de insetos para fornecer evidências que possam auxiliar no desdobramento de processos judiciais, sendo um dos seus principais objetivos a estimativa do intervalo pós-morte (IPM). Um dos ramos da Entomologia Forense, a Entomotoxicologia, tem como princípio utilizar insetos como matrizes para a detecção de drogas, metais pesados, pesticidas e outras substâncias, bem como analisar os efeitos destas no desenvolvimento dos insetos, podendo ser uma ferramenta muito útil em casos forenses em que matrizes como urina, sangue e órgãos internos não estão mais disponíveis, além de aumentar a precisão do IPM. Apesar das possibilidades, a Entomotoxicologia é uma ciência relativamente nova, possuindo algumas limitações. Nesse contexto, esta pesquisa teve como intuito analisar artigos de autores que atuam no Brasil relacionados à Entomotoxicologia, buscando identificar os principais avanços recentes dessa ciência, suas limitações metodológicas, bem como perspectivas futuras nessa área de investigação científica no Brasil. Para tanto, foi realizada uma pesquisa bibliográfica utilizando a palavra-chave “Entomotoxicology” nas plataformas Google Acadêmico, Periódicos Capes, PubMed e Scielo. Foram selecionados 30 artigos correspondentes à pesquisa. A análise dos estudos demonstrou que as moscas do gênero Chrysomya foram as mais presentes nos estudos e, entre elas, Chrysomya megacephala foi a mais estudada. Ademais, foram encontradas algumas lacunas de conhecimento na área, além de uma falta de padronização entre os estudos. Consequentemente, são necessários mais estudos, uma maior integração entre profissionais da criminalística e pesquisadores, bem como mais investimentos na área para sua devida consolidação no Brasil.
Forensic entomology is a science based on the use of insects to provide evidence that can be helpful in the unfolding of legal proceedings and one of its main purposes is the estimate of the post-mortem interval (PMI). One of the branches of forensic entomology, entomotoxicology has as principle the use of insects as matrices for detecting drugs, heavy metals, pesticides and other substances as well as analysing the effects of these substances on theit development of the insects and it can be a very useful instrument in forensic cases in which matrices such as urine, blood and internal organs are no longer available, in addition to increasing the accuracy of the PMI. Despite the possibilities, entomotoxicology is a relatively new science and has some limitations. In this context, this research aimed to analyse articles related to entomotoxicology by authors who work in Brazil seeking to identify the main recent advances of this science, its methodological limitations, as well as future perspectives in this field of scientific investigation in Brazil. For this purpose, a bibliographic search was carried out using the keyword “entomotoxicology” on Google Academic, Capes Periodicals, PubMed and Scielo platforms. Thirty articles corresponding to the research were selected. The analysis of the studies showed that flies of the genus Chrysomya were the most present in studies and among the flies Chrysomya megacephala was the most studied. Moreover, some knowledge gaps in the area were found in addition to lack of standardization in the studies. Therefore, more studies are necessary as well as greater integration between forensic science professionals and researchers and more investments in order to properly consolidate this field in Brazil.
