Leia MaisCom o objetivo de diminuir ainda mais as barreiras que impedem a aprendizagem dos alunos de EAD em Ciências Biológicas, produzimos este manual simplificado de coleta de insetos e formação de insetário, complementado com informações sobre entomologia forense e técnicas alternativas utilizadas pelos biólogos no preparo e armazenagem dos insetos. Esperamos que através deste manual produzido com informações obtidas em sites universitários, artigos científicos e livros didáticos os alunos tenham a oportunidade de aprofundar seus conhecimentos em entomologia além de verificarem a disponibilidade de informações confiáveis em diferentes sites sugeridos ao final do manual. Todas as críticas e sugestõ...

Leia MaisDiversos insetos podem nos ajudar muito na investigação e resolução de diversos crimes, como casos de homicídios. Mas como exatamente eles participam deste processo? Insetos necrófagos são atraídos ao corpo em decomposição, alimentando-se de sua matéria orgênica e depositando ovos e larvas aque ali se desenvolverão. Em uma cena de crime, o perito criminal coleta larvas, ovos e pupas para identificá-los posteriormente e com base no ciclod e vida de cada espécie, é possível estimar o tempo mínimo que se passou desde a morte da vítima, o que pe muito importante para descartar e confirmas suspeitos. Além disso, os insetos podem nos trazer a informação de consumo de substâncias tóxicas pela vítim...
