In the search for new, cheaper and environmentally sustainable sources of protein-rich food, much research has shown the alternative role that insects could play in animal feed. Fly larvae or maggots have been identified as a food source that is very rich in protein, dietary fat, vitamins and minerals. The most commonly used maggots in animal feed are those of the housefly (Musca domestica L. 1758) and the black soldier fly (Hermetia illucens L. 1758). Different maggot production systems for these two fly species have been developed and others are still being developed in different contexts around the world. The production of these maggots does not require much expenditure as they can be easily obtained from animal and/or plant waste available free of charge or at low cost. This study summarizes the available literature on the methods of production of maggots of these two fly species and their use in animal feed. Also, the zootechnical performance of animals fed with maggots and the importance of maggots were discussed in this study.
Bobo-Dioulasso city in Burkina Faso was subject to research conducted on the effects and uses of information and communication digitization in a context of personal, cultural and social change where Internet users freely express their opinions on websites commonly known as social networks. Therefore, what are the effects and logics behind the use of social networks? Is not digitization of information and communication a virtual transposition of actual daily life? Is this freedom of expression part of e-democracy in Burkina Faso? This research which lasted three (3) months raises the issue of users’ styles and their logic behind the use of social networks. The research methodology is based on a rational choice of thirteen social actors. Tools used for data collection include semi-structured interview guide and participant observation. Based on the results obtained, it appears that the effects and uses of information and communication digitization update the anthropological theory of « homo communicators ». It also appears that the uses and logic of the use of social networks show a pluralism of the global-local (glocal) expression. Lastly, the pluralism of the « glocal » expression does not stem from e-democracy but rather from the technical / technological, individual and collective logic.
