Abstract

Pseudovadonia livida (F.) (Coleoptera Cerambycidae Lepturinae) is a widely distributed and common species across Europe. This study was undertaken to investigate some aspects of the sensory and behavioural ecology of P. livida adults in relation to flowering plants they visit. First, their electroantennogram (EAG) responses to 42 synthetic plant volatile compounds were recorded.The antennae gave the strongest EAG responses to methyl anthranilate, methyl salicylate and 2-phenylethyl alcohol. In a field trapping experiment, P. livida beetles preferred fluorescent yellow and yellow traps over white, blue and transparent traps. When we compared different chemical lures, loaded with EAG-active compounds and their blends, in fluorescent yellow traps, we found that the beetles responded stronger to the two-component blend of methyl anthranilate and 2-phenylethyl alcohol than to other lures tested. In a subsequent experiment testing different ratios of these two compounds, the highest number of P. livida adults was recorded in traps baited with a ratio of 1:1 (100 mg of each compound) of methyl anthranilate and 2-phenylethyl alcohol, followed by traps with the 10:1 ratio. Thus, 1:1 and 10:1 blends of methyl anthranilate and 2-phenylethyl alcohol in fluorescent yellow traps are suitable for detection and monitoring of P. livida.
