Abstract
Abstract The work suggests importance of monitoring apple tree pests from moth group in growing conditions of Nitra, Slovakia. In 2014 there was observed occurrence of moths e.g. Codling moth (Cydia pomonella L.), Appleseed moth (Grapholita lobarzewskii Now.), Hawthorn berry moth (G. janthinana Dup.), and Summer fruit tortrix moth (Adoxophyes orana Fish. v. Roesl.) in the apple tree orchard located in the Botanical Garden of SUA in Nitra with help of pheromone traps. The date of first generation occurrence of Codling moth, Appleseed moth and Summer fruit tortrix moth was recorded on April 23. All the pests showed two peaks of flight activity, but with Hawthorn berry moth three periods of higher occurrence were recorded. The course of temperatures influenced number of pests trapped in traps remarkably. The number of pest individuals was highly influenced by rainy weather and lower temperatures in months when there was expected their highest harmfulness. The recorded values might be influenced by plant species diversity of the experimental orchard as well as that of the surrounding area.
