Colorado potato beetle, Leptinotarsa decemlineata Say., belongs to the category of insects that showed the fastest resistance development against almost all insecticides. Therefore in recent years growing trend of application of alternate methods in protection of potato plant from this pest was observed.

The aim of this study was to investigate anti feeding effect of essential oil of Tanacetum parthenium (L.) Schultz-Bip. (Asteraceae), and their constituents (camphor and alpha-pinene) on potato beetle.

The essential oil used in our investigations was submitted to qualitative and quantitative analysis by GC-FID and GC-MS on two different fused silica capillary columns (DB-WAX and HP-1).

The experiment with Colorado beetle was conducted in laboratory condition at 26°C. The influence of the essential oil and their components was tested, both with adults and larvae, with five repetitions each. The results were evaluated statistically.

It was found that camphor gave the best protection of potato leaf mass from pest. The protective effect of the essential oil was lower, while alpha-pinene did not posses any statistically significant protective activity. Although the anti feeding effect on both developing stages of investigated pest, adults and larvae, was observed, it was much more expressed
