Artvin, Erzincan ve Erzurum illerinden 1992-1996 ve daha önceki y›llarda toplanan Chrysomelinae (Coleoptera, Chrysomelidae) türleri üzerinde yürütülen bu faunistik ve sistematik çal›flma sonucunda; 12 cinse ait 34 tür tespit edilmifltir. Bunlar ars›nda Chrysolina cuprina (Duftchimit), C.geminata (Paykul), C. hyrcana Weise, C. trapezicollis Bechyné, ve Timarcha hummeli Falderman türleri Türkiye faunas› için yeni kay›tt›r. Chrysomela collaris L., C.populi L., C.salceti (Weise) ve Plagiodera versicolora (Laicharting)’n›n kavak ve sö¤üdün tomurcuk, yaprak ve sürgünlerinde, Gonioctena linnaeana (Schrank), Phratora vitellinae (L.) ve P. tibialis (Suffrian)’in sögüt yapraklar›nda, Gonioctena fornicata (Brügg.)’n›n yoncada, Leptinotarsa decemlineata (Say)’n›n ise patates bitkisinde zarar yapt›¤› tespit edilmifltir. Di¤er taraftan, Gastrophysa viridula caucasica Jolivet’in ladin fidan üretim alanlar›nda problem oluflturan Rumex alpinus L. yabanc› otu ile biyolojik mücadelelde kullan›labilece¤i ortaya konmufltur.

This faunal and systematic study on the subfamily Chrysomelinae (Coleoptera, Chrysomelidae) is based on material collected from Artvin, Erzincan and Erzurum provinces during 1992-1996 and previous years. 34 species belonging to twelve genera were recorded. Among them, Chrysolina cuprina (Duftchimit), C. geminata (Paykul), C. hyrcana Weise, C. trapezicollis Bechyné and Timarcha hummeli Falderman are new records for Turkish fauna. Chrysomela collaris L., C. populi L., C. salceti (Weise) and Plagiodera versicolora (Laicharting) were determined as willow and poplar pest, Gonioctena linnaeana (Schrank), Phratora vitellinae (L.) and P. tibialis (Suffrian) as willow pest, Gonioctena fornicata (Brügg.) as alfalfa pest and Leptinotarsa decemlineata (Say) as potato pest. Furthermore, Gastrophysa viridula caucasica Jolivet has a potential use in the biological control of Rumex alpinus L., that is a significant weed species in spruce (Picae sp.) plantations. A short description was made for each species, and drawings of body parts having taxonomic importance were enclosed. Keys to the genera and species were prepared . The host plants of some species were recorded. Their distribution in the research area, other parts of the country and in the world was included.
