Elm leaf beetle is one of the most important pests of Elm trees at adult stage and especially at larval stages. In this research work, the contact toxicity and nutritive indicators of Cinnamon, Peppermint, and Eucalyptus have been investigated. The experiments were performed in five densities with three repetitions for each essential and for each life stage of the elm leaf beetle at 25±1C0 and relative humidity of 60±5 percent for 16 hours in daylight and 8 hours in darkness in vitro. The results obtained from biometry data showed that with an increase in density of the essential oils, the mortality rate of elm leaf beetle at different stages of their life increased for all the three essential oils. Based on these results, the essential oil of Cinnamon proved to have the most effect at different stages of elm leaf insect by creating 80 percent mortality relative to the two essential oils of eucalyptus and peppermint after 24 hours. Furthermore, with an increase in the density of the essential oils, the nutritive indicators at the second. instar larva were also reduced. Statistical analysis of variance showed that the relative rate of second instar larva (PCR) in cinnamon essential oil in three concentrations of LC25, LC35 and LC50 compared with the control group was more meaningful compared with the two other essential oils at 5 percent and nutrition inhibition was positive for all the essential oils especially for cinnamon essential oil.  The findings indicate that Cinnamon essential oil compared to Peppermint, and Eucalyptus essential oils is a more suitable candidate to control this pest.   Manuscript profile

2 - Investigation of effects of toxicity and healthy eating (nutritional) index of Cinnamomum, Rosmarinus officinalis L. and Lavandula angustifolia L. essential oils on biological stages of Xanthogaleruca luteola (Coleoptera: Chrysomelidae)

Xanthogaleruca luteola (Coleoptera: Chrysomelidae) is considered as one of the most important pests of Ulmus trees at the adult insect stage, especially at the larval stages. The effect of toxicity and nutritional indicators of essential oils of Cinnamomum zeylanicum L., Rosmarinus officinalis L. and Lavandula angustifolia L. on different biological stages of X. luteola investigated under standard environmental conditions. Four replications were considered and after 24 hours, losses were counted. LC50 values for toxicity of C. zeylanicum L., R. officinalis L. and L. angustifolia L. essential oils on adult X. luteola were estimated to be 11.57, 28.83 and 737.87 ppm, respectively, indicating that Cinnamomum essential oil is more toxic than other essential oils. With increasing concentrations of essential oils, eating indicators of second-instar larvae reduced. The relative consumption rate (RCR) of second-instar larvae in Cinnamomum essential oil at concentrations of LC25, LC35 and LC50 showed a significant difference with the control treatment at the level of 5%. The results of essential oil analysis showed that cinnamaldehyde (91.8%), 1, 8-cinnamol (37.8%) and borneol (8.4%) are the predominant compounds in C. zeylanicum L., R. officinalis L. and L. angustifolia L. essential oils, respectively. Increased nutritional inhibition in Cinnamomum essential oil compared to R. officinalis L. and L. angustifolia L. essential oils can be attributed to the strong toxicity of cinnamaldehyde available in this essential oil. The study results show that Cinnamomum essential oil is a more suitable option for controlling this pest than R. officinalis L. and L. angustifolia L. essential oils. Manuscript profile

Mulberry whitefly Aleuroclava jasmini sensu lato is the most important pest of trees in recent years in Tehran. Many plants have physiological and behavioral effects, such as repellency and deterioration of pests. Their effects were first evaluated with direct planting of plants Rosmarinus officinalis, Lavandula angustifolia and Pelargonum hortorum, and the method of establishment of Mulberry whitefly on them. In this research, with the release of Mulberry whitefly in wooden cages under controlled conditions for three days, the number of adult and egg whitefly laying on the leaves of the plants listed in a completely randomized design with four replications was investigated. Based on the results, the level of pest deposition on the tested plants was lower than the control. Also no egg was observed on any of the treatments. Therefore, these plants, in addition to preventing the laying of pests, have a good repellency and deterrent effect and can be used as a control solution in urban green space. Manuscript profile
