Systematics, speciation, insect-plant coevolution
Berlocher is interested in insect-plant coevolution and the effect it has on insect systematics. His research concentrates on the fruit flies of the family Tephritidae (Diptera), particularly the economically important genus Rhagoletis. In an effort to understand speciation and host race formation in these flies, he has used behavioral, chromosomal, ecological, and genetic approaches. He has made much use of the technique of gel electrophoresis of enzymes to study the genetic differentiation of populations. His interests in addition to Rhagoletis include coevolution between the Tephritidae and the Compositae, insect biogeography, and the general use of biochemical methods in insect systematics.
