Speciation occurs when gene flows between groups of individuals of one species is reduced to such an extent that the genetic differences that have accumulated over time produce barriers to reproduction between the groups. A number of different factors, such as differentiation in food choice and mate choice, can contribute to such a process of reproductive isolation. In her research, Sabine Hänniger investigates the mechanisms underlying the three prezygotic isolation barriers between the corn and rice strains of the noctuid moth Spodoptera frugiperda, to determine possible interactions between these barriers and how they contribute to the speciation process.
