Masten Milek, T., Šimala, M., Koric, B., Xiong, J.J., & Bjeliš, M. 2007 Status of scale insects (Coccoidea), family Coccidae, on grapes in 2006 in Croatia with emphasis on rariry of second generation of Parthenolecanium corni (Bouche) and Parthenolecanium persicae (Fabricius).. Lectures and papers presented at the 8th Slovenian conference on plant protection, Radenci, March 6-7 2007. Plant Protection Society of Slovenia Ljubljana, Slovenia
Notes: During monitoring of Coccoidea on grapes in 2006 we noticed mass outbreaks of Parthenolecanium corni (Bouche), Parthenolecanium persicae (Fabricius), Pulvinaria vitis (Linnaeus) and Neopulvinaria innumerabilis (Rathvon). Neopulvinaria innumerabilis is a new insect species in Croatia. P. corni and P. vitis were present in many vineyards in continental part of Croatia in very high population, but mass outbreaks of P. persicae and N. innumerabilis was in Istria. Different varieties of grape vine weren't equally subservient to different species of scales of family Coccidae. In 2006. we recorded 2 generations of P. corni and P. persicae even though our literature has data only about 1 generation of this species.
