Abstract

Linalool was identified as the main component of the mandibular gland secretion in females and males of four species of Colletes bees, viz., C. cunicularius, C. daviesanus, C. impunctatus and C. succinctus. It was also shown to be the dominant volatile compound in the same gland in male C. floralis (the female of this species has not yet been investigated). Further, in another species, C. similis, linalool is present in the mandibular gland secretions of females and males, but the dominant volatile component in these secretions is geranial, together with neral. Females of the species C. fodiens seem to lack monoterpenes altogether; nonadecane is the dominant volatile compound of the cephalic secretion (based on analysis of a single individual). When linalool is put out in the area of nest aggregation of C. cunicularius, where the males are "patrolling", a distinct increase in flight activity is noted. The function of linalool is discussed on the basis of field observations.
