support: wafer, non nutritive support: sawdust). For the tests with nutritive support the concentrated extract and four dilution were evaluated (1/2, 1/4, 1/6, 1/8). For the non nutritive support, a quantity of 1g for 4ml of each concentrated extract was tested. A coupling between the extracts was carried out to evaluate the effect of synergy. The tests were realized on adult insects. Concerning the first support, the results did not show any insecticidal effect. Some extracts especially from toxic plants showed death rates between 20 and 80% by using the sawdust. The coupling of the extracts did not increase the insecticidal effect. This study has demonstrated that the extracts of certain plants contain bioactive substances which can be used as source of bioinsecticide against Blattella germanica. Key words: Bio-insecticide, Blattella germanica, medicinal plants, poisonous plants, sawdust. 5.14 Digestive Tract Histological Disorder of L5 Locust Schistocerca gregaria (Orthoptera, Cyrtacanthacridinae) After Ingestion of Peganum harmala L.

In the present work, we tested the effect of this plant on the gut histology of the 5 th nymphal instar of the desert locust. Because, is insect since consumes this plant despite that it be toxic. As the result, there was significant histological disorder in the digestive tract of the treated insect compared to the control. Such disorders were manifested mainly in the midgut. However there was no similar disorder observed in the foregut and hindgut of the treated insects. The present results revealed the effectiveness of the Peganum harmala against the desert locust in causing detrimental histological disorders in its mesenteron. Keywords: Peganum harmala, Schistocerca gregaria haemolymph. 5.15 Preliminary Study of the Effects of Rootstocks and Viroids on the Essential Oil Composition of the Sweet Orange “The Maltaise Demi Sanguine” Chammem Nadia 1 , Najar Asma 2 , Sifaoui Ines 3 , Jribi Chokri 3 , and Ben Abderrabba Manef 3 1 Institut National des Sciences Appliquées et de Technologie (INSAT), Centre urbain Nord.

The presence of E.O in the different tree organs may be influenced by factors affecting the plant status. In the present work, this influence has been studied in relation with viroid infection and the root stock species in the case of Tunisian Maltaise cultivar that was grafted on Citrumelo swingle and Citrus macrophylla and inoculated with exocortis and cachexia viroids. The analysis of terpenic composition of those E.O in the fruit exocarps showed that (i) Maltaise/Citrumelo swingle association of trees infected by exocortis gave two folds less of terpinen-4-ol and terpineol than the control. At the qualitative level, exocortis infection in this case induced biosynthesis of new molecules e.g. n-decanal, cis- 115
carveol and δ- selinene, but inhibited others e.g. valencene. (ii) In the case of Maltaise/ Citrumelo macrophylla, cachexia reduced three times the quantity of limonene and nootkatone than exocortis and (iii) Maltaise/ Citrumelo swingle contained five folds more of linalol and two folds more of terpinen-4-ol and terpineol, than Maltaise/ Citrus macrophylla. Keywords: Cachexia, essential oils, exocortis, maltaise, rootstocks. 5.16 Repellence and Anti-Oviposition Activities of Plant Products on Greenhouse Whitefly Dehghani , Mahsa 1, 2 ., and Ahmadi , Kamal 1 1 Department of Plant Protection, Faculty of Agriculture, Shahid Bahonar University of Kerman. 2 Member of Young Researchers Society, Shahid Bahonar University of Kerman, Kerman, Iran. <strong>Abstract</strong>: The greenhouse whitefly, Trialeurodes vaporariorum Westwood (Homoptera: Aleyrodidae), is an important cosmopolitan pest of many crops. Chemical control for the management of greenhouse whitefly has resulted in development of resistance and outbreak of population. So, Secondary metabolites of some plants have been successfully used for integrated control of the pests. The present study investigated the repellent and anti-oviposition activities of essential oils and aqueous extracts from Achillea millefolium and Thymus vulgaris against this pest in greenhouse condition. The cucumber plants with 5 fully expanded leaves were sprayed with the chemicals at 40 µl/ml concentration and control plants were treated with distilled water. Also, the essential oil of A. millefolium at the same volume (5 ml) (for avoid the phytotoxicity effect on the cucumber plant) were sprayed on the special filter paper (2×4 cm) attached at the petiole plant. Four treated plants with the plant derived chemical and four control plants were placed randomly in to a cage (60 × 60 × 80 cm). Three days after spraying with the plant products, approximately 250 whitefly adults were released into the cages. Then three and six days after infesting with the greenhouse whitefly, the number of eggs and adults on detached cucumber leaf were recorded. Each experiment was repeated two times at the same greenhouse condition. The results revealed that all plant products affected on the oviposition and tropism behaviors of greenhouse whitefly. Among different treatments, the highest anti-oviposition effect was calculated by aqueous extracts of T. vulgaris (62.87%) six days after treatments. After 9 days, the anti-oviposition effect caused by all the chemicals ranged from 41.80% to 49.33% in aqueous extract and essential oil of A. millefolium, respectively. Moreover, the aqueous extract of A. millefolium had highest repellent effect (52.54%) six days after treatments. Also, to compare repellent effect of the chemicals on greenhouse whitefly, the highest repellent effect observed with the essential oil of A. millefolium (48.07%) nine days after treatments. These results showed that A. millefolium and Thymus vulgaris had relatively long lasting repellent and anti-oviposition activities on the adults of the greenhouse whitefly. Key words: Achillea millefolium, anti-oviposition activities, greenhouse whitefly, Thymus vulgaris., 5.17 Insecticidal Activities of Five Plant Derived Chemicals on Thrips tabaci Lindeman Hakimeh Najmizadeh 1,2 , Kamal Ahmadi 1 , and Asieh salari 1,2 1 Department of Plant Protection, Faculty of Agriculture, Shahid Bahonar University of Kerman. 2 Member of Young Researchers Society, Shahid Bahonar University of Kerman, Kerman, Iran. <strong>Abstract</strong>: Natural compounds originating from plants might be potential alternative pesticide that are not persistent in the environment and are safe to non-target organisms and human for use in sustainable agriculture. During this project, ethanolic extracts (30 µl mL -1 ) of Melia azedarach L. (Fruits), Peganum harmala L. (seeds), Calendula officinalis L. (seeds), Ferula assafoetida L. (Resin) and Cercis siliquastrum L. (seeds) were applied against 1-2 and 5-6 day old of Thrips tabaci Lindeman. All the experiments were conducted by spray test bioassay in laboratory and ethanol (95%) was used as control treatments. The results indicated that all the used plant derived 116
