Spiders play a crucial role in reducing the infestation ratio of field crop pests. These arachnids act as natural predators, effectively controlling pest populations that would otherwise damage crops. Their presence in agricultural fields helps maintain a balanced ecosystem, reducing the need for chemical pesticides and promoting sustainable farming practices. By preying on various pests, spiders contribute significantly to the health and productivity of field crops, ensuring better yields and healthier plants. The sucking pests are favorable prey for it, as are the first and second instars of cotton leafworm. This study was carried out during two successive years 2022-2023 to survey the spider species associated with some field crops in Dakahlia Governorate in Egypt. A survey study was conducted to determine the presence of 19 families, 43 genera, and 49 spider species associated with the bean plant crop (Phaseolus vulgaris). The relationship between temperature and the number of spiders in El Dakahlia Governorate was studied.
