ABSTRACT

The egg-to-adult viability and the developmental time of Drosophila subobscura is strongly modified by the accumulation of larval biotic residues of D. pavani, D. immigrans, and D. melanogaster. This effect could be an important regulatory factor for this species in nature.

Keywords: Larval interactions; Drosophila subobscura; Drosophila in Chile.
