This study was Keywords conducted on twenty five of the most important medicinal Survey, medicinal and and aromatic plants in two gardens Zoheria in Cairo and aromatic plants, insects, Orman in Giza Governorates. The results indicated that spiders and Egypt. presence of twenty four species of insect pests belongs to fourteen families and five orders. Moreover, eighteen species of spiders belong to nine families and one order (Araneae) were recorded. All these insect pests were presented in low to medium numbers causing moderate damage. From Zoheria garden the largest number of insect pests belonging to orders, Hemiptera, Thysanoptera and Lepidoptera were recorded on sweet marjoram, mints, Jasminum azoricum and rosemary. The dominant spider families recorded with largest number of species . These are : Philodromidae and Theridiidae on jasmine flower, lavender and night-blooming jasmine at Zoheria garden whereas, the same families was dominant on rose, rose geranium and chamomile at Orman garden. The dominant insect orders Hemiptera, Thysanoptera, Diptera and Lepidoptera were recorded on rose, sweet basil and calendula at Orman garden. Introduction According to the World Health variety of insect pests in a single crop. Organization, 80 percent of the Like other plants, medicinal plants too population of developing countries relies have to bear the devastating effects of on traditional plant based systems of injurious insect pests, which are not only medicine to provide them with primary harmful for the plant but also, deteriorate health care needs (Agarwal and the quality of the produce, thus Upadhyaya, 2006). The large scale hampering its medicinal value. The cultivation of these plants in countries majority of the pests caused in feeding may face the problem of sudden damage on reproductive or vegetative appearance of large populations of organs (those under Thysanoptera and 368 Abo-Zaed et al., 2019 Heteroptera, including the Thripidae, to record the insect pests and spiders Miridae, Pentatomidae and associated with important medicinal and Pseudococcidae families), whereas aromatic plants in countryside. others cause erosion or tunnels on heads Materials and methods (Noctuidae), leaves (beetles) or roots This work was conducted on (Elateridae) (Conti, 2003).

Thirteen species of insect kill insects, piece of cotton moistened pests belong to eight families and five with chloroform put in each sample and orders were recorded on Calendula left for 15 minutes. The sample was plants. While twelve insect pests belong emptied in Petri dish and cleaned from to nine families under six orders were plant residues. Then it was examined recorded on chamomile plants under stereomicroscope to separate and (Solaiman, 2015). count the major insect pests. This True spiders are one of the most process was performed at weekly abundance predatory groups in terrestrial intervals throughout the entire period of ecosystems.
