A new species,first report of a male and new distributional records for five species of Oligosita Walker(Hymenoptera:Trichogrammatidae) from China

Seven species of the genus Oligosita, a wellknown cosmopolitan genus of the family Trichogrammatidae that comprise egg parasitoids of coleopteran, hemipteran, lepidopteran and thysanopteran insects, are reviewed. Oligosita xinyangensis sp. nov.(Hymenoptera, Trichogrammatidae) is described in detail and illustrated;the male of O. nigroflagellaris Lin is reported for the first time. New distributional data are provided for O. japonica Yashiro, O. mediterranea Nowicki, O. pallida Kryger, O. polioptera Lin and O. shibuyae Ishii from China, and a key to all the Chinese species of the genus is given.

Serological marking of <Emphasis Type="Italic">Pnigalio agraules</Emphasis> (Hymenoptera: Eulophidae) for field dispersal studies

The parasitoid wasp Pnigalio agraules (Wlk.) is a key natural enemy of the horsechestnut leafminer Cameraria ohridella Deschka and Dimić (Lepidoptera: Gracillariidae). As a basis for mark-release-recapture studies, aimed at investigating the dispersal of this parasitoid in the field, adults of P. agraules were marked using a vertebrate-specific immunoglobulin (IgG). The marker was later detected by double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA). The IgG was either applied externally by spraying or internally by feeding an IgG-enriched diet. Different concentrations of the marker were used and the influence of abiotic (climatic conditions, time elapsed between marking and marker examination) and biotic factors (sex and age of the parasitoids) on the detection of the immunomarker was tested. External marking by spraying led to more homogeneous labelling than feeding the marker. Parasitoids labelled with 0.25 mg rabbit IgG per ten individuals contained enough immunomarker to be easily distinguished from unmarked ones. Neither the climatic conditions nor the sex or age of the insects had an influence on the detection of the marker. The IgG remained well detectable during the entire lifespan of the parasitoids, which was not negatively affected by the marking procedure. Serological marking can be used to investigate the dispersal behaviour of beneficial insects within mark-release-recapture studies.
