The 3rd European Workshop on Sea Buckthorn (EuroWorkS2014) was held in Naantali, Finland on 14th to 16th of October 2014 under the theme “Producing Sea Buckthorn of High Quality”. Conference concentrated on three topics that were recognized to be current under the theme: sea buckthorn fly, cultivation technology and standardization of sea buckthorn. A special attention was paid to sea buckthorn fly because of its rapid and destructive invasion to Europe. Protective measurements need to be studied fast to get this new pest under control. Also long-term strategies are needed in order to continue efficient berry production, also without pesti- cides. Dr. Ljubov Shamanskaja has a long research experience with sea buckthorn fly in Barnaul, Rus- sia, where the fly has been a problem over 20 years.

  • Identification Key to the Subfamilies of Ichneumonidae (Hymenoptera)
    Identification key to the subfamilies of Ichneumonidae (Hymenoptera) Gavin Broad Dept. of Entomology, The Natural History Museum, Cromwell Road, London SW7 5BD, UK Notes on the key, February 2011 This key to ichneumonid subfamilies should be regarded as a test version and feedback will be much appreciated (emails to [email protected]). Many of the illustrations are provisional and more characters need to be illustrated, which is a work in progress. Many of the scanning electron micrographs were taken by Sondra Ward for Ian Gauld’s series of volumes on the Ichneumonidae of Costa Rica. Many of the line drawings are by Mike Fitton. I am grateful to Pelle Magnusson for the photographs of Brachycyrtus ornatus and for his suggestion as to where to include this subfamily in the key. Other illustrations are my own work. Morphological terminology mostly follows Fitton et al. (1988). A comprehensively illustrated list of morphological terms employed here is in development. In lateral views, the anterior (head) end of the wasp is to the left and in dorsal or ventral images, the anterior (head) end is uppermost. There are a few exceptions (indicated in figure legends) and these will rectified soon. Identifying ichneumonids Identifying ichneumonids can be a daunting process, with about 2,400 species in Britain and Ireland. These are currently classified into 32 subfamilies (there are a few more extralimitally). Rather few of these subfamilies are reconisable on the basis of simple morphological character states, rather, they tend to be reconisable on combinations of characters that occur convergently and in different permutations across various groups of ichneumonids.

In many countries, Aphidoletes aphidimyza (Rondani) has been used effectively as a biological control agent against aphids, particularly in greenhouses. In Japan, A. aphidimyza was reg- istered as a biological control agent in April 1999, and mass-produced cocoons have been imported from The Netherlands and United Kingdom since mass-rearing methods have not yet been estab- lished. In recent years, the effect of imported A. aphidimyza on aphid populations was evaluated in greenhouses at some Agricultural Experiment Stations in Japan. However, no striking effect has been reported yet from Japan. The failure of its use in Japan seems to be caused chiefly by the lack of detailed ecological or behavioral information of A. aphidimyza. Therefore, we investigated its ecological and behavioral attributes as follows: (1) the survival of pupae in relation to the depth of pupation sites; (2) the time of adult emergence in response to photoperiod during the pupal stage; (3) the importance of a hanging substrate for successful mating; and (4) the influence of adult size and nutrient status on adult longev- ity and fecundity. (1) A commercial natural enemy importer in Japan suggests that users divide cocoons into groups and put each group into a plastic container filled with vermiculite to a depth of 100 mm. However, we believe this is too deep for A. aphidimyza pupae, since under natural conditions mature larvae spin their cocoons in the top few millimeters to a maxmum depth of 30 mm.

A total of 4982 specimens be­ longing to 475 different species \vere collected. Extrapolations from double-log functions revealed that there may be as many as 1330 parasitoid species present per year. 455 of the 475 species were parasito­ ids. 155 of them attack dipterans. 48 lepidopterans. 36 beetles. 23 wasps, 22 plant hoppers and 13 ap­ hids. 47 of the species are egg-parasitoids and parasitoids of miners. ectophytophages count for 44 of 2 the \V asp species. The abundance of the wasp fauna was rather high ( 1120 ± 53 in d. m- a- I ( 1986) and 2 1 335 ± 42 ind. m - a- ( 1988). Most abundant were the parasitoids of miners, gall-makers and the egg­ parasitoids. Compared \vith the high abundance the biomass was low. In 1986 the wasps weighed a total 2 1 2 1 of 194 ± 24 n1gDW m- a- and in 1988 only 69 ± 20 mgDW m- a- . The parasitoids of ectophytopha­ gous lepidopterans and coleopterans counted for n1ore than half of the whole biomass.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).
