The study aimed to use integrated control factors to control the life aspect of whitefly on crops and evaluate the efficiency of chemical and biological pesticides against pests. Chemical pesticides were sprayed on the leaves. Alafsket chemical pesticide recorded the highest mortality rate with the increase in the period of exposure to the pesticide, as it recorded mortality (5-15) days from the treatment of the plant with the pesticide. All pesticides were used on the plant with three concentrations of Baronas the treatment - Oxymatrin to test the effectiveness of the pesticide against the insect, and the chemical pesticides used (Alafsket - the corrected percentage mortality for egg mortality when using the Afiskat pesticide after five days of treatment reached 94.4 compared to the rest of the other chemical treatments. Either in the primary nymphal stages, the offset pesticide recorded corrected mortality within five days of treatment, with an average of 95.2. As for the adult experience, the corrected percentage of mortality during three days of treatment was 86.6. As for the biological pesticides used in the experiment (Bacillus thuriengiensis - Beauveria bassiana - Entomopathogenic nematodes for both sexes - Heterohabditis sp - Steinernema sp- Basilomyces lilacinus) The treatment results of the used biocides were revealed by the superiority of the suspension of insect-pathogenic nematodes of both sexes in giving them high mortality in eliminating the treated insect stages. The results of the treatment for the first stages of the nymphs were recorded with the superiority of the nematode suspension, which gave corrected mortality for the nymphs amounted to 93.6 within five days of treatment. As for the adult experience, the nematode suspension had higher mortality than other biological treatments. The adult mortality was 77.7 within three days of treatment
