ABSTRACT

Phytochemicals have long been touted as alternatives to synthetic chemicals for pest control and especially interest has grown for the search of antifeedants effects over the last decades. Similarly, we tested antifeedant activity of essential oils obtained from four different Lamiaceae species; Thymus transcaucasicus RONNIGER, Thymus pseudopulegioides KLOKOV and DES.-SHOST, Thymus leucotrichus HAL. and Teucrium polium L., against Agelastica alni L., Coleoptera: Chrysomelidae larvae. Thymus leucotrichus showed the most powerful antifeedant effect of the four plant species during the three days (r = 0.481, P < 0.01) the highest AFI value (AFI = 41.055) was obtained on the second day at 2000 ppm (P < 0.05). At the same time, the first and third day's treatments showed strong positive correlation between dose and AFI indices [1th day; r = 0.890, P < 0.01 and 3th day; r = 0.918, P < 0.01]. According to these results, Thymus leucotrichus essential oil is the most effective phytochemical against A. alni larvae.
