Oberea

Abstract: New faunistic data are presented on Cerambycidae of the subfamilies Lepturinae, Cerambycinae and Lamiinae of Turkey. The faunistic data in the present paper on almost all species add to knowledge of their distribution in Turkey. In the present paper specimens were studied of Lepturinae, Cerambycinae and Lamiinae in T. C. Ministry of Agriculture-Nazife Tuatay Plant Protection Museum, Ankara, Turkey. Preliminary study of the specimens in the Museum has been done by Tuatay et al. Thirty one species were recorded belonging to nineteen genera from the Museum. However, we have recorded eighty four species and five subspecies belonging to forty three genera for Turkey from the Museum with our paper. Opsilia uncinata (Redtenbacher, 1842) is reported for the first time for Turkey with exact locality. Cortodera humeralis (Schaller, 1783), Pogonocherus hispidus (Linnaeus, 1758), Coptosia sancta (Reiche, 1877), Helladia pretiosa ssp. fatima (Ganglbauer, 1884), and Agapanthia detrita Kraatz, 1882 are the second records for Turkey. Dorcadion albolineatum Kuster, 1847, D. bangi Heyden, 1894, D. lameeri Thery, 1896, D. semilineatum Fairmaire, 1866, D. septemlineatum ssp. septemlineatum Waltl, 1838, D. septemlineatum ssp. abanti Braun, 1976, D. crux Bilberg, 1817, Oberea (s.str.) ressli Demelt, 1963 and Agapanthia fallax Holzschuh, 1973 are endemic taxa for Turkey. Also, many taxa are new records for the provinces of Turkey.

Abstract: The beetle Oberea erythrocephala, whose larvae mine stems and roots of leafy spurge (Euphorbia esula L. # EPHES), was introduced into Oregon, Montana, and Wyoming between 1980 and 1984. Although it was not recovered in Oregon and Wyoming, it became established at two of three release sites in Montana and appears to be accepting leafy spurge plants at a fourth.

Abstract: In many parts of the world where soybean is grown, a few species of Coleoptera have adapted to feeding, during the larval stage, within the stems of soybean plants. Most of these species are in the Cerambycidae, but at least one species, in southern Brazil, is in the Curculionidae. The following cerambycid species have been recorded in association with soybean: in the United States, Hippopsis lemniscata (F.) (Genung and Green 1965) and Dectes texanus texanus LeConte; in Peru, Grammopsoides rufipes Breuning (M. E. Irwin, personal communication); in India, Oberea brevis Swederus (Gangrade 1974); and in Australia, Zygrita diva Thomson (Jarvis and Smith 1946). The curculionid recorded as a stem borer in southern Brazil is Sternechus subsignatus Boheman (Corseuil et al. 1974).

Abstract: The taxonomy, distribution, life-history and host plant relationships of the cerambycid Oberea erythrocephala (Schrank), an oliphagous, univoltine stem- and root-miner of Euphorbia spp. are discussed. The results of feeding and oviposition tests with 43 plant species in 20 families, and of larval transfer tests with 31 plant species are presented, and show that O. erythrocephala is restricted to certain species of the genus Euphorbia, not including the ornamental species E. pulcherrima and E. milii. In Europe the beetle is widely distributed and locally quite destructive. It accepts the target weed, Canadian leafy spurge, and develops normally on it and therefore should be relatively easy to establish in the field. The release of O. erythrocephala in Canada is recommended. Zusammenfassung Studien uber Oberea erythrocephala (Schrank) als moglichem Mittel zur biologischen Bekampfung von Euphorbia spp. in Kanada Es werden die Taxonomie, Verbreitung und Lebensweise des Bockkafers Oberea erythrocephala, eines oligophagen, univoltinen Stamm- und Wurzelminierers bei Wolfsmilch, Euphorbia spp. in Kanada erortert. Die Ergebnisse von Futterungs- und Eiablage-Versuchen an 43 Pflanzenarten aus 20 Familien sowie von Larven-Obertragungen auf 31 Pflanzenarten zeigen, das die Existenz von O. erythrocephala auf bestimmte Arten der Gattung Euphorbia, z. B. nicht auf E. pulcherrima und E. milii, beschrankt ist. In Europa hat der Kafer weite Verbreitung. Er entwickelt sich auch in der kanadischen Wolfsmilch und konnte daher in Kanada relativ schnell auf den Feldern Verbreitung finden. Seine Freilassung in Kanada zur biologischen Unkrautvernichtung wird daher empfohlen.
