Experiments were conducted in Qaha, Qalubiya governorate under field conditions during two successive seasons (2020-2021 and 2021-2022). This work aims to study the impact of eco-friendly methods in controlling the population density of pests that infest cucumber crops. Data showed a significant difference between the general weekly mean number of the pests (Bemisia tabaci (Genn.), Thrips tabaci (Lind.), Aphis gossypii glover, and Tetranychus urticae Koch) investigations, whereas the F values were 31.85 and 23.48 individuals for two successive seasons, respectively. The results showed, in general, that the number of pests was greater in the second season compared to the first season, and it was found that the whitefly B. tabaci was the most prevalent pest on the cucumber crop during the two seasons studied. According to the results, the use of the recommended pesticide, N-P-K 20-20-20, N-P-19-19-19, was followed by the use of amino acids, then humic delta, which was the most affected compound and had the lowest yield compared to the other compounds.
