Laboratório de Tecnologia Educacional BIBLIOTECA DIGITAL               DE CIÊNCIAS

Coletar insetos em locais de convívio dos alunos e classificá-los, utilizando uma chave taxonômica de identificação.

Com 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...

O objetivo é ilustrar e mostrar de forma simples como se dão alguns aspectos da vida dos insetos, como eles são caracterizados, suas principais estruturas e como eles se comportam em conjunto, como é o caso da vivência das formigas e seus papéis dentro de um fomigueiro.

Imagem ilustrando uma mosca detetive, fazendo um trocadilho com legistas que atuam na área forense de entomologia, onde os insetos fornecem informações para interpretação de situações investigativas voltadas a área em questão.

IMAGEM COM VARIOS INSETOS, COM FUNDO COM ALGUMAS FOLHAS E NO CENTRO OS DIZERES

Diversos 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...

ESTE EPISÓDIO DO PODCAST VOZES DA NATUREZA É VOLTADO PARA DIVULGAR CONHECIMENTO SOBRE O INCRIVEL MUNDO DOS INSETOS.

Muitos pensam que insetos não possuem utilidade alguma. Mas você sabia que eles podem nos ajudar a resolver crimes? Eles podem ser extremamente úteis em investigações de casos de homicídio, negligência e maus-tratos, contaminação alimentar, tráfico de drogas e até crimes ambientais, por meio da

Podcast acerca do tema Entomologia Forense. Neste podcast, iremos conversar com uma doutoranda na área de entomologia forense, que irá esclarecer algumas dúvidas sobre o tema, explicando como os insetos podem nos ajudar a desvendar crimes!

Infográfico voltado para o público infantil mostrando as fases do desenvolvimento de um inseto com desenvolvimento holometábolo

Distribution: Eastern South America from French Guyana to northern Argentina and as far west as Mato Grosso and eastern Bolivia. Habitat: Lives in humid grasslands, wetlands and ponds. Diet: Feeds mainly on insects and seeds, but also on fruits. Reproduction: Often nests in groups. The nest is built in a fork of a tree. Both male and female build the nest watering the material before using it. The nest is a deep basket. Natural history: The vocalization is melodic and commonly the predomi...

Physical appearance: 40 cm. The feet are red and webbed. The chest is brown, as well as the face that is a bit darker. There is a patch of iridescent feathers in the wings. When flying it shows a large white spot at the back of the wing. The male has a red beak and the female’s is blue. The Female also has white spots on the face. Distribution: From Venezuela to Argentina. Habitat: Wetlands, lakes, ponds and rivers even in polluted places. Diet: Feeds on seeds, leaves and small invertebrates. The hatchlings are goot at catching insects. Reproduction: Lays up to 14 bluish or greenish eggs. When the adult realizes the presence of a potential predator it distracts its attention...

Physical appearence: 12cm. The upper parts are grayish with black and ferruginous stripes The chest is light brown with spots in the immature. There are yellow ribbons above the eyes and in the wings. The coloration may change when it is dirty due to contact with earth. Distribution: The Grassland Sparrow is found east of the Andes from Colombia to central Argentina but is missing from the Amazon Basin upstream from the Tapajós river. Habitat: Dry fields with grass, cerrado and crops. Diet: Feeds on grains and small insects. Reproduction: During the breeding season they live in pairs in a territory defended by the male. The nest is opened and placed on the ground. The eggs are s...

Physical appearance: 36 cm. The legs are short and yellow. The body is predominantly grey, darker in the back. The top of the head is black. The immature is striated and brownish. Distribution: American Continent, Africa, Asia, Australia and islands in the Pacific. Habitat: Rivers, lakes and mangroves of different sizes. Diet: Aquatic insects, mollusks, amphibians, reptiles and fish. Reproduction: The nest is a platform on the top of tall trees. Lays three eggs. Natural history: Solitary and migratory. There are saw-like structures inside the beak to help holding slippery food. May be eaten by carnivorous fish such as the trahiras (Hoplias sp.) when walking on flooded land....

Length: 20cm Identification: nightjars are always very difficult to identify as they are nocturnal birds, rarely seen during the day due to their camouflage. On the other hand there are few species inhabitting urban areas and among these the little nightjar is usually the smallest and with the lightest color pattern. Distribution: it is distributed through all the South American countries east to the Andes. Habitat: occurs in a wide range of ecosystems, but is specially common in forest edges surrounded by crops and wetlands. This nightjar spends the whole day quiet and very well camouflaged on the ground and thus is rarely seen at daylight. It only flies during the day ...

Physical appearance: 11 cm. The upper parts are dark and the inferior parts yellow. There is a white bar in the supercilium. The females are smaller than the males.

35cm Similarly to other Brazilian jays, the Curl-crested jay has white lower parts and blue and black upper parts. It may be confused with the Plush-crested jay (Cyanocorax chrysops), but while the last presents the crest in the back of the head, the yellow iris and a blue patch around the eyes, the Curl-crested jay presents the crest on the forehead, the red iris and the head is entirely black. Whereas the Old World ravens are mostly black, as well as the crows, the Brazilan corvids are colorful and most of them have white lower parts. There are 6 species of jays in Brazil, all of them extremely beautiful. The Curl-crested jay is one of Brazilian’s noisiest jays. To make the noise ...
