Abstract

Pollen beetles (Coleoptera: Nitidulidae) rank among the most important pests of oilseed rape (Brassica napus). For their timely detection in early spring, yellow sticky or water pan traps are used; however, it has been suggested that the addition of chemical lures to attractive visual cues could improve trap efficacy. During the course of field trials in Hungary, we have developed a 3-component synthetic floral lure consisting of (E)-anethol þ (E)-cinnamyl alcohol þ (E)-cinnamyl acetate, which attracted large numbers of pollen beetles into large capture-capacity fluorescent yellow funnel traps. There was no apparent difference between the pollen beetle species Brassicogethes aeneus F. 1775 (earlier Meligethes aeneus), Brassicogethes viridescens F. 1775, Brassicogethes coracinus Sturm 1845 and Fabogethes nigrescens Sturm 1845 in their responses to the 3-component lure, which can therefore be used to trap all of them. Funnel traps with the new ternary floral lure were more efficient in catching beetles than those with lures containing 2-phenethyl isothiocyanate, a previously described plant-derived attractant for pollen beetles. However, the effect of the
addition of the isothiocyanate to the ternary blend was not completely clear from these experiments and thus requires further studies.
