摘要

rudnevi Oobius（Nowicki，1928）（膜翅目：Encyrtidae）首次在伊比利亚和南欧使用哨兵蛋报道。2016年7月，在埃斯特雷马杜拉（西班牙西南部）的三片橡树空地上发现了这种寄生蜂，这三片空地分别位于阿尔门德拉尔（La Jara）和梅里达（La Serrana和Cornalvo自然公园）。O.rudnevi对尾角Cerambyx cerdo Linnaeus，1758（其迄今为止唯一已知的宿主）和C.welensii（Kuster，1845）的卵进行了对位，后者构成了一个新的宿主-寄生蜂组合（C.welensii-O.rudnavi）。寄生虫率在不同地点和日期之间变化很大（范围为0-93%），cerdo的患病率高于welensii。在野外和实验室进行了新的研究，以探索O.rudnevi在地中海橡树开放林地的生态、行为和寄生潜力。

Primer registro en la Península Ibérica de Oobius rudnevi (Nowicki, 1928) (Hymenoptera: Encyrtidae), un parasitoide oófago poco conocido de Cerambyx sp. (Coleoptera: Cerambycidae)

Oobius rudnevi (Nowicki, 1928) (Hymenoptera: Encyrtidae) is first reported from Iberia and southern Europe using sentinel eggs. The parasitoid was detected in July 2016 in three oak open woodlands in Extremadura (SW Spain), located in Almendral (La Jara) and Merida (La Serrana and Cornalvo Natural Park). O. rudnevi para-sitized both the eggs of Cerambyx cerdo Linnaeus, 1758 (its only known host to date) and C. welensii (Kuster, 1845), which constitutes a new host-parasitoid association (C. welensii-O. rudnevi). Parasitism rate was quite variable among sites and dates (range 0–93%), with a higher prevalence in C. cerdo than in C. welensii. New studies are conducted in the field and laboratory to explore the ecology, behaviour and parasitic potential of O. rudnevi in Mediterranean oak open woodlands.

期刊介绍： Graellsia was fist published in 1943 and the journal name honours Mariano de la Paz Graells. For 44 years the journal was devoted to Iberian entomology, but in 1987 it started publishing papers on zoology in general. More recently, Graellsia has restricted its scope and currently publishes original and unpublished papers on Zoological Diversity, including taxonomic, faunistic, biogeographic, chorological, evolutionary and conservation studies. Notes, news and book reviews are also published in the corresponding sections. Formerly Graellsia was published by CSIC with financial support from the Ministry. When this financial support for spanish scientific journals ceased, Sociedad de Amigos del Museo Nacional de Ciencias Naturales stepped in to take care of journal edition, with the goal of contributing to the advance of knowledge in Zoology.
