	abstract = {The weekly intensive survey showed that two major aphid species, are widely prevalent in the alfalfa agroecosystem including the black alfalfa aphid Macrosiphum sp. and the spotted alfalfa aphid Therioaphis trifolii (Monell). A rich fauna of true spiders (Araneae) was also recorded as foliage-dwelling spiders that belong to 6 major families. Three major predominant spider families arranged by their percentage presence included Philodromidae (24.09\%), Thomisidae (21.09\%), Salticidae (16.58\%). However, other less predominant families included Zodariidae (4.68\%) Gnaphosidae (4.22\%), N Therididae (3.80\%), Lycosidae (3.01\%). Araneidae (2.51\%), Cithaeronidae (0.40\%), Agelenidae (0.88\%), Pholcidae (0.38\%) and Clubionidae (0.33\%). A linear correlation existed between the total numbers of spider complex and the total number of the spotted alfalfa aphid showed an appreciable synchrony with the population of the highly prevalent host (prey) throughout the year.},
