Criação e manutenção de Tenebrio molitor L. (coleoptera, tenebrionidae): um relato de caso

Abstract

The search for alternative protein sources has driven studies on socio-environmentally and sustainably produced food. In this scenario, Tenebrio molitor L. presents itself as an excellent option for animal and human food, combining very high protein content with economic viability. Therefore, this study aimed to report the practical experience gained in the laboratory management and maintenance of mealworm colonies. Cultivation was carried out in plastic boxes measuring 30 cm long by 18 cm wide and 10 cm high, using wheat and corn as substrate and food source. The moisture necessary for the insects' development was provided through tubers, vegetables, and alternative means of water supply, with food changes and cleaning performed almost daily. The management routine consisted of manually separating the insect's life stages, as well as cleaning the boxes and removing feces/frass. During the experience, it was observed that the main challenges for maintaining a healthy colony were moth infestation and high pupal mortality caused primarily by flies, requiring frequent interventions. It is concluded that mealworm management has great practical viability, but it is evident that the success of entomoculture depends directly on the rigorous control of environmental and sanitary factors on a daily basis.
