Abstract

The present investigation aims to study the monitoring of the whitefly B. tabaci adult susceptibility (Genn) in five Governorates, Giza, Behira, Gharbia, Faiyoum and Dakahlia. by evaluation the efficacy of some insecticides from organophosphorus compounds which still used in controlling some pests, such as Pirimiphos-methyl, Profenofos, Chlorpyrifos-methyl, Cyanofenphos and Diazinon. Dakahlia Governorate strain was the most susceptible one among all, followed by Giza, strain while Gharbia strain was the most resistant one.
In addition survey of pesticide residues in cabbage samples collected at random from local markets of the same Governorates in Egypt showed that, some pesticides were detected, however, others were not detected. The results revealed that cabbage samples were contaminated with different amount of pesticide residues. No pesticide exceeded the MRL in samples.
