Abstract
Three morphological mutations were detected in the Mediterranean fruitfly. The mutations involve eye color, color of the pupae, and number of cephalic chaetae. All 3 mutations are recessive and autosomal. The eye color mutation and pupae pigment mutation are single-gene mutations. The mutation involving the cephalic chaetae may also be a single-gene mutation, but requires further confirmation since it leads to decreased viability. The results of the various crosses suggest that all 3 mutations lead to lowered viability. Two of the mutations, eye color and number of cephalic chaetae, are linked. It is proposed that these morphological mutations can serve as markers for ecological studies and genetic control of the fruitfly.
