The authors studied the number of Macrolepidoptera individuals and species caught by light-trap, in relationship with the geomagnetic M-index.A correlation was found between the averaged geomagnetic M-index values measured at night, and the number of individuals and species caught by light-trap in the Kámon Botanic Garden (Hungary).The authors studied the number of Macrolepidoptera individuals and species caught by light-trap, in relationship with the geomagnetic M-index.A correlation was found between the averaged geomagnetic M-index values measured at night, and the number of individuals and species caught by light-trap in the Kámon Botanic Garden (Hungary).

The study deals the efficiency of pheromone trapping of the seven harmful Microlepidoptera species depending on the ozone content of air. Between 2004 and 2011 Csalomon type pheromone traps were operating in Bodrogkisfalud (48°10’ N, 21°21’ E; Borsod-Abaúj-Zemplén County, Hungary, Europe). We calculated relative catch values from the number of caught insects. We assigned these to the ozone values, we averaged them, and we depicted the results together with the regression equation though. We established that the pheromone trapping of this species is most fruitful when the ozone content of the air is high. By contrast, low ozone values reduce the successfulness of the catching to a moderate level. Our results will be exploitable in plant protecting and environment conservation research.
