The seasonal activity of flea beetles in Bulgaria
Journal of Pest Science 82 (3), 295-303
Abstract: Using allyl-isothiocyanate-baited traps, we recorded six species of flea beetles in cabbage and horseradish crops in the region of Sofia, Bulgaria in 2006 and 2007. The most abundant species in the traps was Ph. cruciferae (92-96%) followed by Ph. vittula, Ph. undulata and Ph. nigripes. The overwintering adults of these species emerge before the beginning of April and are active to the end of May-beginning of June. Catches of adults of the new generation occurred from the end of June-beginning of July to the second half of October-beginning of November. In 2006, air temperature and humidity strongly influenced the catches of the flea beetles. Investigations of the reproductive status of field collected females of Ph. cruciferae showed that this species develops one generation per year in the region. The results of this study can be used in integrated pest management approach to flea beetles control.
