Abstract
The results of an investigation of scale insects (Hemiptera, Coccoidea) in Estonia, Latvia and Lithuania are presented. The majority of samples were collected during 10 days in August 2012; further data is included based on samples collected from Estonia in November 2006, and Lithuania in January 2011 and July 2012. The following are new country records: 18 species for Estonia, species collected outdoors, Asterodiaspis variolosa (Ratzeburg), Aulacaspis rosae (Bouché), Chionaspis salicis (L.), Diaspidiotus bavaricus (Lindinger), Eulecanium tiliae (L.), Newsteadia floccosa (De Geer), Orthezia urticae (L.), Parthenolecanium corni (Bouché), P. pomeranicum (Kawecki), Peliococcus calluneti (Lindinger), Phenacoccus aceris (Signoret) and Physokermes hemicryphus (Dalman), and on indoor plantings, Aspidiotus nerii (Bouché), Coccus hesperidum L., Planococcus citri (Risso), Pseudococcus longispinus Targioni Tozzetti, Rhizoecus dianthi Green and Spilococcus mamillariae (Bouché); five species for Latvia, species collected outdoors, Diaspidiotus bavaricus, D. gigas (Thiem & Gerneck), D. ostreaeformis (Curtis), Eriococcus pseudinsignis Green and P. pomeranicum; and one species for Lithuania, on indoor plantings, Chrysomphalus aonidum (L.). Revised checklists of scale insects are presented for each of the three countries.

Didžioji dalis duomenų surinkta 2012 metų rugpjūtį visose šalyse, Estijoje 2006 metų lapkritį bei Lietuvoje – 2011 metų sausį ir 2012 metų liepą. Nauji duomenys: 18 registruotų rūšių Estijoje, skydamariai surinkti atvirose cenozėse, Asterodiaspis variolosa (Ratzeburg), Aulacaspis rosae (Bouché), Chionaspis salicis (L.), Diaspidiotus bavaricus (Lindinger), Eulecanium tiliae (L.), Newsteadia floccosa (De Geer), Orthezia urticae (L.), Parthenolecanium corni (Bouché), P. pomeranicum (Kawecki), Peliococcus calluneti (Lindinger), Phenacoccus aceris (Signoret), Physokermes hemicryphus (Dalman), ir uždarose cenozėse, Aspidiotus nerii (Bouché), Coccus hesperidum L., Planococcus citri (Risso), Pseudococcus longispinus Targioni Tozzetti, Rhizoecus dianthi Green, and Spilococcus mamillariae (Bouché); penkios rūšys Latvijoje, skydamariai surinkti atvirose cenozėse, Diaspidiotus bavaricus, D. gigas (Thiem & Gerneck), D. ostreaeformis (Curtis), Eriococcus pseudinsignis Green, and P. pomeranicum; viena rūšis Lietuvoje, skydamariai surinkti uždaroje cenozėje, Chrysomphalus aonidum (L.).
