Abstract
Spiders are among the most abundant predators recorded on date palm trees in Beni-Suif and Qaluobia Governorates. They are voracious predators, and combined with their high abundance, which play an important role in the reduction of different pests' populations. Field trials were conducted in QaluobiaandBeni–SuifGovernorates during the period of October 2013 to October 2014 to show he incidence of different spiders. Obtained data recorded that the collected predaceous spiders were identified into 14 families in Beni-Suif included 11 families recorded in Qaluobia as follows; Theridiidae, Philodromidae, Thomisidae, Lycosidae, Linyphiidae, Gnaphosidae, Dictynidae, Miturgidae, Araneidae, Tetragnathidae, Agelemidae, Scytodidae, Filistadae and  Uloboridae. Also a ratios of these count, indicated that an average of 25 % of spider families and spices were absent from palm in Beni–Suif Governorate. On the other hand, under these families recorded 19 species of predator. The most numerous spiders species collected from date palm phoenix dactylifera at Beni–Suif Governorate were 227 individuals of Steatoda pykuliama, while the high number of predators species collected from Qaluobia Governorate were 223 individuals of Filistata hibernalis.
