“…), suggests that the compound may not have a strong attractive eVect on E. hirta when presented alone. The improved ternary attractant described in the present study may improve eYciency of mass trapping From the two EAG-active compounds which were tested in Weld experiments, methyl salicylate is a very widespread Xoral scent constituent, and has been found in many plant families Tollsten 1993, 1995;Jakobsen et al 1994;Flamini et al 2002;GrisonPigé et al 2002). Methyl salicylate has been described as an attractant for several beetles (Wolde-Havariat et al 2007;Maekawa et al 1999;Rutledge and Young 2007;Hammack 2001;Kamm and Buttery 1984;Dickens 2006).…”

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.

Behavioural and chemical ecology underlying the success of turnip rape (Brassica rapa) trap crops in protecting oilseed rape (Brassica napus) from the pollen beetle (Meligethes aeneus) Abstract There is increasing interest in the use of trap crops as components of integrated pest management (IPM) strategies. Understanding the mechanisms underlying host plant preferences of herbivorous pests can lead to improved effectiveness and reliability of the trap crop. We investigated the behavioural and chemical ecology underlying the success of turnip rape, Brassica rapa, trap crops in protecting oilseed rape, Brassica napus, from the pollen beetle, Meligethes aeneus, which feeds in the flowers and lays its eggs in the buds causing yield loss. Using a semi-field arena bioassay, plant growth stage was found to be a major factor in the preference of this pest for B. rapa over B. napus. Plants at early-flowering growth stages were preferred over plants in the bud stage, irrespective of species. No preference was found when both species were flowering. As B. rapa develops faster than B. napus in the field, this could explain part of the mechanism of its success as a trap crop. However, B. rapa was preferred over B. napus when both species were in the bud stage, indicating some inherent preferences for B. rapa. Responses of M. aeneus in olfactometer tests to the odours of B. napus and B. rapa at the bud and flowering growth stages, reflected those of the semi-field arena bioassay. These behavioural responses can be explained by volatile compounds associated with the flowering stage. Phenylacetaldehyde, indole and (E,E)-a-farnesene were found to be present in air entrainment samples of both plant species at the flowering growth stage, but only in those of B. rapa at the bud stage. The former two compounds were behaviourally-active in olfactometer tests. These compounds are likely to be involved in host location by M. aeneus, and, at least partially, responsible for the attractiveness of B. rapa and its success as a trap crop to protect B. napus from this pest.
