THE PHEROMONE TRAP CATCH OF HARMFUL MOTHS IN CONNECTION WITH SOLAR ACTIVITY FEATURED BY QINDEX

The paper deals with connections between solar flare activities and pheromone trap collection of harmful moth species. The authors have worked out the pheromone catch data of Spotted Tentiform Leafminer (Phyllonorycter blancardella Fabricius, 1781), Peach Twig Borer (Anarsia lineatella Zeller, 1839), European Vine Moth (Lobesia botrana Denis et Schiffermiiller, 1775), Oriental Fruit Moth {Grapholita molesta Busck, 1916), and Plum Fruit Moth (Grapholita funebrana Treitschke, 1846) as were operated for the period of 1988 and 1993-2007 in Borsod-Abauj-Zemplen County (Hungary). The results proved that the daily catches were significantly modified by the Q-index, expressing the different lengths and intensities of the solar flares. On days with high Q-index relative to the ones of the average swarming periods, the number of catches is considerably lower.
