Seasonal flight of the potato tuber moth, Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae) in three regions in Bulgaria established by pheromone traps
Acta Phytopathologica et Entomologica Hungarica 48 (1), 75-86
Abstract: Two-year seasonal monitoring of the flight of Phthorimaea operculella using pheromone traps was organized at four sites in three districts in Bulgaria: Sofia, Kyustendil, and Plovdiv. Comparison between sticky traps and dry funnel traps has shown that sticky traps were much more effective in capturing of males of this pest than the dry ones. The results of our investigations showed that the pest could appear in the field as early as the end of March and also intensive flight could be observed up to the end of November. Single catches were registered even in January. However, because of the overlapping of the generations, their number and periods of moth emergence was not possible to be distinguished by the catches in pheromone traps. Analyses of climatic data (mean air temperature and mean rainfall) indicated that none of the climatic variables investigated strongly affected the P. operculella trap catches.
