Zusammenfassung

Hybrid incompatibility (HI), the inviability or sterility of interspecific hybrids, is a ubiquitous phenomenon that hinders the genetic exchange between species. Thus, by acting as a reproductive isolation barrier, HI plays an important role in speciation. Several genes causing HI have been recently identified and characterized in Drosophila and even in higher taxa. HI in lepidopterans however has hardly been studied on a molecular level. Using two lepidopteran genera whose representatives either belong to two distinct species or to two strains of one species that are believed to be in...
