Abstract :
Wheat sawfly larvae, Dolerus puncticollis (Tenthredinidae; Hymenoptera) were detected in wheat fields of Moghan (Ardebil province, Iran) for first time. A bioassay experiment was carried out to determine the susceptibility of D. puncticollis to an entomopathogenic nematode species Steinernema carpocapsae and indoxacarb. Probit analysis showed high susceptibility of D. puncticollis larvae to S. carpocapsae with LC , LC and LC values of 20 50 80 1.1, 4.5 and 18 infective juveniles per larva, respectively. The LC , LC and LC values of 20 50 80 indoxacarb for D. puncticollis larvae were 0.1, 1.15 and 12.2 ppm, respectively. Due to the extremely low value of LC , this species is very sensitive to indoxacarb possibly reflecting 50 the lack of chemical control history against the pest.
