| Abstract | ||
| This work aims to carried out a study in Algeria on the isolated reproduction between two different populations of Calliptamus barbarus one with three spots on their posterior femoral hind (3 S) living in wet region Jijel, the other with one spot (1 S) collected in the semiarid zone (Djelfa and Kasr El Boukhari). After sampling, the insects were placed in wooden rearing cages on the laboratory. The insects were fed on wheat seedlings mixed with barley bran. The reproductive isolation was positif, but the sexual act is not confirmed. Despite the apparent success in reproductive isolation, the obtained reproductive isolation data do not allow us to corroborate that the two geotypes of C. barbarus are distinct taxa or are experiencing a segregation process. | ||
