ترجمة الملخص

The two-spotted red spider mite Tetranychus urticaeKoch (Acari: Tetranychidae) is a serious pest and present worldwide on a wide range of host plants in both outdoor crops and greenhouses. Synthetic pesticides have been extensively used to control this pest. But the excessive use of these pesticides and their negative effects on human health and environment, in addition to the associated problems of resistance, led to an increasing public demand for natural pesticides. Plant extracts are one of several natural compounds control methods that have recently received increasing attention. In this context, this study aimed to evaluate the efficacy of different part aqueous extracts of 5 plant species against T. urticaeon eggplant (Solanum melongenaL.) under both laboratory and greenhouse conditions. Laboratory experiments were carried out at Faculty of Agriculture, Tishreen university in 2016 by using leaf disc method, and the greenhouse trials were done in eggplant greenhouse at Al-Basah, (5 Km from Lattakia) during 2016-2017 agricultural season by using vaseline rings method. These plant parts used were seeds and leaves of Chinaberry Melia azedarach Linnaeus 1753 (Rosidae: Meliaceae) and Cypress Lemon Cupressus sempervirens Linnaeus 1753 (Pinidae: Cupressaceae), seeds and fruits of River Red Gum Eucalyptus camaldulensis Dehnhardt 1832 (Rosidae: Myrtaceae), flowers and leaves of Oleander Nerium oleander Linnaeus 1753 (Asteridae: Apocynacea) and corms and leaves of Wild Arum Arum maculatum Linnaeus 1753 (Arecidae : Araceae). The effect of part plants extracts were tested for mortality means of studied stages (protonymphs, adult females and egg), and percentage oviposition means to indicate the fertility of females.1.Laboratory results showed that:1.1.The extract of N. oleander leaves was significantly higher than the rest extracts in the effect on the eggs (88.8%) followed by the flowers extracts of N. oleander(87.8%).1.2.Extract of M. azedarachseeds was more effective as toxic effectagainst adult females and protonymphs (74.5-78.4% respectively) followed by N. oleander leaves extracts (60.99-66.1%, respectively).1.3.The highest fertility was shown by extract of C. sempervirens leaves (47.3%).2.Greenhouse results showed that:2.1.Efficacy of the extract of N. oleander leaves on the eggs was 87.4 %, N. oleander flowers extract came second (85.3%). The effects of the rest of plant extracts on eggs hatching were lower than 50%.2.2.The highest death rates of T. urticae at adult females and protonymphs stages were found with M. azedarachseeds extract (65.4, 69.3% respectively).2.3.N. oleander leaves and its flowers and the M. azedarachseeds extracts exhibited the lowest oviposition deterrent activities to T. urticae through out the experiment (8.17, 11.3, 14.4%, respectively). 3.All plant extracts were more effective in the laboratory than in the greenhouse.4.Different Effectiveness of Plant Parts in Effect on T. urticae phases was observed, Seed, fruit and corma extracts were more effective than leaves, which in turn were more efficient than flowers
