A MELANIC FORM OF THE EUROPEAN GRAPE VINE MOTH, LOBESIA BOTRANA DEN AND SCHIFF (LEPIDOPTERA, TORTRICIDAE), AND ITS GENETIC BASIS

摘要

A melanic form of the European grape berry moth, Lobesia botrana, is described from a rearing colony maintained at INRA, Bordeaux, France. From the offspring of the crosses with the typical form, F-1, F-2 and backcrosses, it is established that the melanic form is genetically determined and its inheritance controlled by a single recessive non sex-linked gene (Roe). Likewise, possible practical uses of the genetic marker in field and laboratory tests are discussed.
