We evaluated the degree of reproductive isolation between laboratory populations seed beetle (Acanthoscelides obtectus) selected to reproduce early (E) or late (L) in life, where different levels sexual activity and discrimination have been detected. found a significant level behavioral among within E selection regime which beetles showed enhanced early-life fitness traits low activity. In contrast, substantially higher an indiscriminate mating system inhibited rather than promoted pre-zygotic L populations. Our results indicate that study may be crucial for understanding first steps allopatric subjected uniform selection.
