          Abstract

          Aproceros leucopoda, the zig-zag sawfly, an invasive pest of elms (Ulmus spp.), was found in two separate areas of Germany through July 2014, i.e., a northern area including the states of Berlin, Brandenburg, Mecklenburg-West Pomerania, Saxony and Saxony-Anhalt, and a southern area in Bavaria. A speed of self-dispersal of 45–90 km/yr has been calculated from earlier and present records. Observations of A. leucopoda in Belgium and the Netherlands during 2013, which are 360–610 km distant from records in Germany of that year, are interpreted as resulting from human-mediated jump dispersal. Larvae, feeding traces and cocoons were frequently found on the native elm species U. minor and U. glabra, whereas none could be detected on U. laevis. Other occurrences were often on Resista® elms, causing severe defoliation in a recent planting. New host plant records for A. leucopoda are: U. minor ‘Webbiana’, U. minor var. suberosa, and the Resista® cultivars U. ‘New Horizon’, U. ‘Regal’ and U. ‘Rebona’. The future dispersal of A. leucopoda throughout most of Germany is expected, because at least U. glabra and U. minor are widespread in this country.

          World Catalog of Symphyta (Hymenoptera)

          The first complete World Catalog of sawflies (Hymenoptera, suborder Symphyta) for over 100 years is presented. It contains references to the original descriptions and provides brief distributional data for 803 genera, 8353 species (123 with two or more subspecies) and 161 subspecies in addition to the nominal subspecies. 15245 proposed names are treated, including replacement names, infrasubspecific names and nomina nuda, of which only 22 could not be checked in the original publications. Current taxonomic placement of genera and species and occurrence in zoogeographic regions are indicated. The list of names contains 31245 name combinations, variant spellings and family-group names. The authors attempted to consult all publications with taxonomic content referring to Symphyta that have appeared up to 31.12.2009. The 2960 cited references include all those that are known to contain original descriptions of taxa. Short biographical data and portraits of 168 symphytologists as well as images of representatives of extant sawfly taxa are included.

              Sawfly poisoning in sheep and goats.

              In September 1984 some sheep in a flock of 250 suffered depression, anorexia, incoordination and difficulty in rising; 50 ewes and weaners died. Post mortem examination revealed petechial bleeding, massive acute liver necrosis and in some animals degeneration of the kidney tubules. The rumen and gut contained many larvae of the blue-black birch sawfly (Arge pullata). Laboratory and field observations indicated that these were the cause of the illness.
