Research Interests

I am interested in finding the honey bee's (Apis mellifera) QTLs of resistance to Varroa destructor. The aim of the study is to find practical ways to manage honey bees by fighting the parasite in the hive system using the resistance traits of the host rather than using external sources of parasite control like acaricides.
