Fennica 23: 121–126. In recent years, there have been significant outbreaks of the European sunflower moth (ESM) Homoeosoma nebulella in northern China, causing enormous agricultural losses to local farmers. Although some control measures have been investigated,thereislimitedknowledgeaboutgeneticstructureamongESMpopulations which may be related to pest outbreak. In this study, we analyzed the geneticvariationandgeneticstructureofESM.Ourresultsshowedthatgeneticdifferentiation was low among populations (2.73%), while it was high within individuals (60.73%), and among individuals within populations (32.59%). DendogramsbasedonF st andgeneticdistancerevealedthatpopulationsfromInnerMongoliaandXinjiangUyghurAutonomousRegionwerefirstclusteredand subsequently grouped with populations from Heilongjiang province. The outbreaks of ESM in Inner Mongolia may be caused by dispersal of ESM from Xinjiang Uyghur Autonomous Region.
