    Nyckelord :reproductive interference; habitat selection; modelling; phytophagous insects;

    Sammanfattning : Host plant selection is an important process during the life cycle of lepidopterans, providing ovipositing sites for adults and food resources for the larvae. The processes behind host plant selection have been extensively studied, especially in closely related species in the context of niche separation. LÄS MER
