Abstract | ||||
A glass vial technique was developed to estimate the insecticidal activities of some organophosphorus, carbamate, pyrethroid and (OP + IGI) insecticides to both pink and spiny bollworms. Also, monitor of field populations for resistance to tested insecticides was followed. Responses of susceptible strain were compared with those collected from the fields at Kafr EI-Dawar . El-Bouheira Governorate during 1997 and 1998 . Data indicated high resistance levels to the pyrethroid fenvalerate, the OP chlorpyrifos and the carbamate thiodicarb and to the two insecticides11G1 mixtures namely delfos and empire in pink bollworm field strain showing a: 34.84, 101.4, 105.5, 104.6 and 129.58 fold, of resistance, respectively. While spiny bollworm was in the tolerant stage with : 3.31, 2.81, 2.75, 3.89 and 3.45 folds, respectively. The calculated LC90 from Lc-p lines were used as discriminating concentration to determine resistance in both PBW and SBW in 1998. | ||||
