Özet

In this study, the toxic effects essential oils obtained from six Satureja species (Satureja cilicica P. H. Davis, Satureja cuneifolia Ten, Satureja hortensis L., Satureja spicigera (C. Koch) Boiss., Satureja thymbra L. and Satureja montana L.) were investigated on the adults and larvae of Colorado potato beetle (Leptinotarsa decemlineata (Say, 1824)). All tests were executed in glass petri dishes and vacuum desiccators including 15 individual for each period with 3 replicates under laboratory conditions. All doses of essential oils conducted in the petri dishes and the desiccators showed that depending on concentration increase and duration of exposure time resulted between 0.0% and 100% toxic effect on the potato beetle larvae and adults. In petri trials, S. thymbra essential oil at the doses of 15 and 20 I per petri and at the first larvae stage after application of 96 hours gave 100% mortality ratio while S. hortensis and S. spicigera essential oils 20 IF per petri dose and at the second larvae stage gave 100% toxic effect. The highest dose (20 I) of essential oils in all times was found to be effective in both petri dishes and desiccators experiment. The mortality ratios were found between 0.0% and 97.7% on all larvae stages and adults in desiccator experiment using essential oils. Among the tested six oils, S. thymbra essential oil was found to be effective in all searched biological periods. The results obtained from this study suggested that the essential oils of tested Satureja species might have use for L. decemlineata larvae and adults as bio-larvicides and insecticides.
