Abstract

We describe a trap comprised of both chemically and visually attractive stimuli for the alfalfa longhorn beetle, Plagionotus floralis (Pallas) (Coleoptera Cerambycidae Clytini), a pest causing increasingly serious damage each year in alfalfa fields in Central and Eastern Europe. Fluorescent yellow funnel traps caught significantly more P. floralis than traps with other colours, although in some tests non-fluorescent yellow traps also attracted more beetles than non-yellow traps. Fluorescent yellow reflects at a high intensity at wavelengths of 500 to 550 nm, which may account for the far better response of P. floralis. A ternary synthetic chemical lure of (E)-anethol, 1-phenylethyl alcohol, and 3-methyl-eugenol (TERN lure) generally increased the catches of P. floralis in the fluorescent yellow traps. 1-phenylethyl alcohol or 3-methyl eugenol used alone in fluorescent yellow traps caught significantly more P. floralis beetles than fluorescent yellow traps with no odour bait. The establishment of a threshold for fluorescent yellow traps with the floral attractant to monitor P. floralis populations would assist in decision making regarding the optimal application of agrotechnical measures. This protocol would improve plant protection practice with respect to both an economic and an environmental concern.
