Abstract
Summary Introduction: Potato ( Solanum tuberosum L.) is an important vegetable crop in Syria. Potato tuber moth Phthorimaea operculella is the main damaging pest of this crop. Many approaches were tried to control it. Objectives : This study evaluates the insecticidal activity of Juniperus foetidissima essential oil and two monoterpenes against potato tuber moth using fumigation bioassays. Methods: Essential oil was extracted from new plant branches of Juniperus foetidissima using Clevenger-type apparatus. Potato tuber moth Phthorimaea operculella , (adults, eggs, larvae, and pupae) were exposed to different concentrations of the essential oil of Juniperus foetidissima for various periods. The significance of differences between treatments at p <0.05 were evaluated by one-way analysis of variance using the mortality percentages data. The LC 50 and LC 90 were calculated by Probit analysis. Results : Essential oil vapor with LC 50 : 0.3 μ l/l air was very effective against potato tuber moth at the adult stage. However; adults sensitivity to monoterpenes varied: Nerol caused a 100% mortality at 0.025 μ l/l air after 6 h, while the same concentration of citronellol caused 98% mortality. The 0.125 µ l/l air concentration of the two compounds caused 100% mortality after 6 h. Conclusion: Results suggest the possibility of using Juniperus foetidissima essential oil as a fumigant to control potato tuber moth infestation in stores.
