Female choosiness and mating opportunities in the blood-sucking bug Rhodnius prolixus

We investigated the relationship between female choosiness and mating opportunities in the blood sucking bug Rhodnius prolixus. Rhodnius prolixus females exhibit active discrimination behaviour to male mating attempts which delays or prevents copulation. Female rejection behaviours can be beneficial...

Female rejection behaviours can be beneficial if mating opportunities are readily available and the pool of males varies in their quality.

Since the availability of mating opportunities is affected by the ratio of sexually active males to females, we randomly assigned focal pairs to arenas with a sex ratio biased toward males, females or without other individuals.
