Abstract

Fatty acids (FAs) from nymphs, females and males of Ixodes ricinus were analysed by gas chromatography/mass spectrometry. Ticks were collected from May to October 2013. The most abundant FAs were 18:1, 18:0, 16:0 and 18:2 which are also dominant FAs of insects. Adults contained higher concentrations of FAs in general than nymphs because they contain more fat body and probably a thicker layer of epicuticular lipids. Larger quantities of FAs > 20 carbon atoms in the carboxylic chain were present in females, which generally show higher content of lipids essential for oogenesis, whereas there were similar amounts of 14–18 in both sexes. In September and October, ticks contained large concentrations of the majority of FAs except for 18:1, the most abundant one in ticks collected from May through August. Thus, most FAs, especially those with more than 20 C atoms, tend to increase at lower temperatures.
