Abstract
The importance of Creontiades pallidus (Rambur) as a pest of cotton grown along the Euphrates river in Syria, was evaluated during 1979 to 1983. Cotton plants grown in cages and exposed to large numbers of the species suffered a yield loss of 54.3%. In field trials, shedding of fruiting bodies was significantly higher in locations with large populations of C. pallidus than in areas where infestations were low. A mean population level of seven specimens per 50 sweeps, from early July till mid‐August, resulted in a yield loss of 50.4%. Control is recommended when C. pallidus reaches a level of seven specimens per 50 sweeps in June or July, but control is not justified when this pest is found in August or later.Keywords
