Invasion Dynamics of A Termite, Reticulitermes flavipes, at Different Spatial Scales in France

摘要: Termites are social insects that can also be major pests. A well-known problem species is the subterranean termite, Reticulitermes flavipes. It invasive in France and thought to have arrived from Louisiana during 18th century. While putative source of French populations has been identified, little known about how termite spread following its establishment. Here, we examined expansion patterns at different spatial scales urban areas clarify R. flavipes France. Based on our analyses phylogeography population genetics, results suggest a scenario successive introductions into Charente-Maritime region, Atlantic Coast. Two fronts formed: one toward northeast other southeast. At regional scale, genetic distribution were observed: there was heterogeneity Ile-de-France aggregation Centre-Val de Loire. local found three focal sites each formed single large colony contained several secondary reproductives. Our findings represent second step efforts reconstruct termite’s invasion dynamics. They highlight role may played by railway network transporting termites over long distances.
