- | Reproductive interference may be defined as any kind of sexual interaction between individuals from different species that reduces the fitness of at least one of them. Even though it is relatively common, reproductive interference is usually ignored as an ecological process than can influence species coexistence and exclusion. | + | Reproductive interference may be defined as any kind of sexual interaction between individuals from different species that reduces the fitness of at least one of them.

- | Reproductive interference can occur for many reasons, one of which is failure to discriminate conspecifics from heterospecifics. This sort of failure is more common among closely related species, which also commonly compete for resources. Such is the case with the ladybug sister species //Harmonia yedoensis// and //Harmonia axyridis//.

This sort of failure is more common among closely related species, which also commonly compete for resources. Such is the case with the ladybug sister species //Harmonia yedoensis// and //Harmonia axyridis//. These species compete and also interfere reproductively with each other. The interference is asymmetrical, |
