Abstract
Medicinal and Aromatic plants (MAPs) belong to a large group of plants with a great interest due to its cosmetic, pharmaceutical and nutritional values. Origanum majorana L., Ocimum basilicmum L., Foeniculum vulgare Mill.and Coriandrum sativum L are the most important medicinal and aromatic plants belonging to families Lamiaceae and Apiaceae in Egypt and Kenya. These plants are desirable host plants to many insect pests. Therefore, this study was included the following:1-Survey of some pests that were infesting Medicinal and Aromatic plants (MAPs) belonging to Lamiaceae and Apiaceae families in the field during 2018-2019 seasons at Fayom governorate and Kenya. 2-Relation between population fluctuation and Evaluated effects of weather factors of some pests that were infesting families Lamiaceae and Apiaceae during the two successive seasons (2018-2019) at Fayum governorate.3- Effect of sap-sucking insects on the quantity and quality of some Medicinal and Aromatic plants (MAPs) essential oil. 4- Efficacy of entomopathogenic nematodes against Spodoptera littoralis (Boisd.) and Agrotis ipsilon (H.) (Lepidoptera: Noctuidae). 5- The efficiency of some treatments on the population density of some pests infesting family Apiaceae. Bioassays were conducted to evaluate the nematode{u2019}s efficiency in the laboratory to kill the insect larvae. The nematode, Steinernema monticolum has killed >90% of the Spodoptera littoralis & Agrotis ipsilon larvae at 400 (IJs)/dish. While mortality percent was 80 and 100% with 100 IJs/dish of Heterorhabditis bacteriophora (HP88) were used against A. ipsilon and of S. littoralis instar insect larvae respectively. These results indicate that the nematode H. bacteriophora (HP88) was more virulent than S. monticolum against S. littoralis & A. ipsilon in the laboratory
