Drosophila suzuki: Matsumura (Diptera: Drosophilidae): analysis of experimental conditions for its rearing and study in the laboratory

Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is an invasive pest species that uses a wide variety of commercial fruit as breeding and feeding resource. The damage to the generated by D. suzukii´ oviposition causes considerable economic losses. Therefore, maintenance in lab conditions constitutes fundamental tool for research proposal. Two determining factors affecting rearing are culture medium density. In this study, we evaluated impact these on three components associated with fitness: development time, larval-adult viability body size, comparing effects media: cornmeal (polenta), mashed potato plum when flies were reared at densities: 10, 30 50 larvae per 5ml medium. Our results revealed lower densities provide better under conditions.
