Pine wilt disease is a severe threat to the native pine forests in East Asia. Understanding the natural regeneration of the forests disturbed by pine wilt disease is thus critical for the conservation of biodiversity in this realm. We studied the dynamics of composition and structure within different plant functional types (PFTs) in Masson pine forests affected by pine wilt disease (PWD). Based on plant traits, all species were assigned to four PFTs: evergreen woody species (PFT1), deciduous woody species (PFT2), herbs (PFT3), and ferns (PFT4). We analyzed the changes in these PFTs during the initial disturbance period and during post-disturbance regeneration. The species richness, abundance and basal area, as well as life-stage structure of the PFTs changed differently after pine wilt disease. The direction of plant community regeneration depended on the differential response of the PFTs. PFT1, which has a higher tolerance to disturbances, became dominant during the post-disturbance regeneration, and a young evergreen-broad-leaved forest developed quickly after PWD. Results also indicated that the impacts of PWD were dampened by the feedbacks between PFTs and the microclimate, in which PFT4 played an important ecological role. In conclusion, we propose management at the functional type level instead of at the population level as a promising approach in ecological restoration and biodiversity conservation. © 2012 Hu et al.

New data on Chinese Tersilochinae are provided: one species, Tersilochus scutatus sp. n., is described from Liaoning province of China and the Russian Far East, and two species, Barycnemis bellator (Müller) and Tersilochus curvator Horstmann, are new records from China. Thus, this work raises the total number of known Chinese species to 31. Two close species, Diaparsis pulchra Khalaim and D. rara (Horstmann), are compared; specimens previously treated as D. rara, var. from the Russian Far East are found to belong to D. pulchra. Tersilochine faunas of China, South Korea and Primorskiy region of Russia are discussed. The fauna of Palaearctic China is still poorly known, being represented by an equal number of genera and somewhat fewer species than the fauna of South Korea, and it is half the size of the fauna of Primorskiy Region of Russia; the Oriental fauna of China, with only four described species, is virtually unknown.

Eight species of the genus Cryptopimpla Taschenberg, 1863 are reported from China, five of them new to science: C. flavipedalis Sheng, sp. n., collected from Ningxia Hui Autonomous Region, and C. rufipedalis Sheng, sp. n. collected from Jilin Province, both from the Palaearctic part of China. Cryptopimpla carinifacialis Sheng, sp. n., C. flavifacialis Sheng, sp. n. and C. maculifacialis Sheng, sp. n. were collected from Jiangxi Province in the Oriental part of China. A key to the species of Cryptopimpla known from China is provided.

Four species of Mastrus Förster, 1869 are reported from China. Two, Mastrus nigrus Sheng & Zeng, sp. n. reared from Arge pullata (Zaddach) and Mastrus rugotergalis Sheng & Zeng, sp. n. reared from Diprion jingyuanensis Xiao & Zhang, are new to science. One, M. deminuens (Hartig, 1838), is a parasitoid of Pachynematus itoi Okutani. A key to species of Mastrus Förster known in China is provided. © M.-L. Sheng, X.-F. Zeng.
