An attempt to control Cameraria ohridella using an attract-and-kill technique
Journal of Pest Science 84 (2), 207-212
Abstract: This study estimates the efficacy of an attract-and-kill (AandK) technique to control the horse chestnut leaf miner, Cameraria ohridella Deschka and Dimic (Lepidoptera, Gracillariidae), an invasive insect pest of the horse chestnut, Aesculus hippocastanum L. (Hippocastanaceae). The AandK formulation was dispensed as 50 μl droplets of paste-like matrix, containing C. ohridella sex pheromone, (8E,10Z)-tetradeca-8,10-dienal (85% + pure; 0.16% w/w) and a fast acting contact toxicant, pyrocides (94% pure; 6% w/w), applied directly to the bark of the trees. It was tested in 2003 at rates of 30 and 45 droplets/tree at the Ostrobramska site and at rates of 30, 60 and 90 droplets/tree at the Woloska site in Warsaw, Poland, for the first insect generation. A set of untreated plots (0 droplets/tree) was established at each site as well. The treatment efficacy was estimated using two indices: (1) moth catches in pheromone traps and (2) the number of mines per leaf. Trap catches were significantly higher in the untreated plots than in the treated plots regardless of the application rate in all sites. However, there were no significant differences in leaf damage amongst all plots on each site. At the "Lazienki Krolewskie" park the attractiveness of two types of pheromone sources were compared: traps were baited with rubber septum lures or with AandK droplets. The catches of C. ohridella in traps baited with lures were lower than captures in AandK droplet-baited traps, but the difference was not significant. Possible reasons for the low efficacy of the AandK method in management of C. ohridella and reducing leaf damage are discussed.
