摘要

板栗瘿蜂(Dryocosmus kuriphilus，膜翅目:板栗瘿蜂科)是一种危害板栗的外来害虫。这种害虫在西班牙的第一次记录是在2012年的加泰罗尼亚，现在它几乎分布在该国所有的栗子种植区。在这项研究中，我们概述了4年期间(2013-2016年)在加泰罗尼亚ACGW中寄生蜂的招募情况，比较了寄生蜂群落对同一地点橡树和栗树瘿虫的攻击。在ACGW虫瘿中共发现了22种通常攻击栎木的本地寄生蜂，以及非本地的中华桃蚜。最丰富的种类是背肉蝇、黄桃蝇、鸭梨桃蝇和绿绒桃蝇。研究还发现，在ACGW的22种原生寄生蜂中，有20种也是由13种栎瘿诱变剂(12种栎瘿科，1种柞蚕科)的瘿中饲养的。

The invasive ACGW Dryocosmus kuriphilus (Hymenoptera: Cynipidae) in Spain: native parasitoid recruitment and association with oak gall inducers in Catalonia

The Asian chestnut gall wasp (ACGW), Dryocosmus kuriphilus (Hymenoptera: Cynipidae), is an invasive pest that affects chestnut trees. The first record of this pest in Spain was in 2012, in Catalonia, and it is now distributed in virtually every chestnut growing area in the country. In this study, we present an overview of parasitoid recruitment by ACGW in Catalonia over a 4-year period (2013–2016) comparing parasitoid communities attacking galls on oak and chestnut trees at the same sites. A total of 22 species of native parasitoids that normally attack oak cynipids emerged from ACGW galls, together with the non-native Torymus sinensis. The most abundant species were Bootanomyia dorsalis, Torymus flavipes, Ormyrus pomaceus and Eupelmus urozonus. The study also found that 20 of the 22 native parasitoids in ACGW galls were also reared from galls of 13 species of oak gall inducer (12 Cynipidae, 1 Cecidomyiidae).

期刊介绍： The journal is inclusive of all subjects, geographical zones and study locations, including trees in urban environments, plantations and natural forests. We welcome papers that consider economic, environmental and social factors and, in particular, studies that take an integrated approach to sustainable management. In considering suitability for publication, attention is given to the originality of contributions and their likely impact on policy and practice, as well as their contribution to the development of knowledge. Special Issues - each year one edition of Forestry will be a Special Issue and will focus on one subject in detail; this will usually be by publication of the proceedings of an international meeting.
