"1991"^^ . "This paper deals with the impact and distribution of phytophagous insects of the family Tephritidae (Diptera) in the flower heads of C. solstitialis registered on the sandy sites in the vicinity of Belgrade. The C. solstitialis flower heads were attacked by the 4 insect species of the family Tephritidae, as follows: Urophora sirunaseva Hg., U. quadrifasciata Mg., Chaetorellia hexachaeta Hering and Achantiophilus helianthi Rossi. Intensity of the attack and number of all the insect species registered in the C. solstitialis flower heads during the summer period ranged from 14% (average: 0.34 insects per flower head in 1989) to 39% (0.73 insect per flower head in 1987). Of all the insect species registered in the C. solstitialis flower heads U. sirunaseva was a predominant species. C. sirunaseva appears to be the predominant in the overwintered ones." . . . .
