Improving the floral attractant to lure Epicometis hirta Poda (Coleoptera: Scarabaeidae, Cetoniinae)

Abstract

In order to improve the eYciency of the known Xoral attractant of Epicometis hirta [(E)-anethol and (E)-cinnamyl alcohol in a ratio of 1:1], candidate synergist compounds for Weld tests were selected through electroantennographic tests using the antennae of female and male E. hirta adult beetles. Among synthetic Xoral compounds 4-methoxyphenethyl alcohol and methyl salicylate evoked high responses from the antennae and were chosen for further Weld studies. In trapping tests in Bulgaria, the addition of 4-methoxyphenethyl alcohol to the E. hirta bait in the ratio of 1:1:1, in Hungary in ratios of 1:1:0.3 and 1:1:1 signiWcantly increased catches. The addition of methyl salicylate was without eVect in both countries. A high-capacity trap supplied with this ternary attractant could be more eYcient for mass trapping purposes of E. hirta in environment-friendly plant protection.

An improved female-targeted semiochemical lure for the European corn borer Ostrinia nubilalis Hbn.

“…It is a component (together with indole) of the floral attractant of Diabrotica barberi Smith and Lawrence (Coleoptera: Chrysomelidae) (Metcalf et al, 1995). In Epicome tis hirta Poda (Coleoptera: Scarabaeidae) the addition of 4METH to the floral attractant consisting of (E)-cinnamyl alcohol+(E)-anethol was synergistic (Vuts et al, 2010).…”

“…Also, in case of different insect species which use plant volatile cues to locate hosts, reports of effective synthetic baits are available (e.g. Tóth et al 2009;Vuts et al 2010). Behavioural response to plant volatiles have also been reported in mirid species (e.g.…”

The Capturing of the Apple Blossom Beetle, Tropinota hirta (Poda) (Coleoptera: Scarabaeidae), by Different Traps in Afyonkarahisar

“…This study drew the same conclusions as the study by Toth et al (2003a) as regards the attractant that the use of (E)-cinnamyl alcohol and (E)-anethol at a ratio of 1:1 are effective in capturing T. hirta. Vuts et al (2009) reported, according to their study, that the addition of (E)-anethol, (E)-cinnamyl alcohol and 4-methoxyphenethyl alcohol, the most common attractant for T. hirta, at a ratio of 1:1:1 increased the rate of capture significantly. The commercial preparation, which was provided for present study as ready-to-use, contains 2-propanol, 1,1-oxybis and dibutylene glycol in addition to (E)-anethol and (E)-cinnamyl alcohol.…”

“…According to the study of Schmera et al (2004), using of light blue traps combined with (E)-cinnamyl alcohol and (E)-anethol at a ratio of 1:1 lures these insects into captivity. Vuts et al (2009) reported that the most effective mixture in arresting T. hirta consists of (E)-anethol and (E)-cinnamyl alcohol and 4-methoxyphenethyl alcohol at a ratio of 1:1:1. Also, Sivcev et al (2006) reported that the most effective color for the capture of T. hirta was light blue.…”
