About the Book

Na zona de Meskine (Maroua, Camarões), foram efectuadas observações (estação seca) sobre espécies inventariadas de Hoverflies em função da diversidade dos recursos alimentares disponíveis. O principal objetivo era encontrar conhecimentos entomológicos que pudessem facilitar o aumento dos rendimentos nas práticas agrícolas, preservando simultaneamente o ambiente no local agrícola. Os inquéritos foram efectuados de três em três dias sob a forma de transectos. As espécies de plantas atractivas para os Syphidae são removidas e o papel funcional de cada espécie de Hoverfly é determinado. Os resultados obtidos permitiram identificar 21 espécies de moscas varejeiras. Estas espécies foram agrupadas em 8 géneros, dos quais se destaca o género Eristalinus com 12 espécies. Outros géneros foram reduzidos a 40%, nomeadamente Toxomerus, Melanostoma, Phytomia, Mesembrius, Asarkina, Paragus e Episyrphus. Foram determinados três grupos com base na frequência de ocorrência destes Syrphidae: espécies constantes, espécies incidentais e espécies acidentais. As visitas florais das moscas listadas foram avaliadas em 26 espécies de plantas, incluindo 8 culturas camponesas fora de época e 20 espécies em torno e entre o espaçamento entre linhas das culturas.
