The Faculty of Agriculture at the University of Zagreb has been dedicated, for almost 100 years, in the education of agriculture and its related sciences; to producing highly qualified experts and developing and broadening professional knowledge in this area. In addition to teaching, scientific research is a fundamental activity undertaken in pursuit of our mission – the improvement of the Croatian agricultural sector. Our faculty holds a leading position in Croatian agricultural science due to success of the large number of scientists, scientific projects and publications. Plant protection and ‘phytomedicine’ takes a very important place in the University studies at the Faculty of Agriculture at all three educational stages: at Undergraduate level, and via Graduate and Postgraduate studies; but also in our other activities connected to life- long learning, and services which support the private sector of Croatian agriculture. In our work we strongly support all activities of our scientists, teachers and students in international cooperation. On behalf of this, I am pleased to thank you for your participation in this meeting. I am delighted to welcome all 60 participants of this meeting who come from 11 different European countries to the 17th IOBC Working Group Meeting on Integrated Control in Oilseeds (ICOC) which we are proud to host in our Faculty. I hope you are going to have successful discussions on your topics regarding the current problems encountered in the production, entomology and plant pathology of oilseed crops in Europe. I believe that this meeting will be a stimulus for all of us to establish further cooperation on improving agricultural production with greater efficiency of plant protection. Dean of Faculty Prof. Zoran Grgić, PhD I II Preface The IOBC Working Group on Integrated Control in Oilseeds (ICOC) will meet for the 17th time in Zagreb, Croatia, September 18-20, 2018, to discuss the current problems encountered in the production of oilseed crops in Europe. As we have already noticed in previous years, the problems observed by us in Europe are very similar to those reported in the other parts of the world: problems with pests and diseases, resulting in crop damage and yield loss. The meeting will comprise both joint and separate sessions devoted to entomology and plant pathology of oilseed crops, with the final get-together summarizing our respective discussions. In such a way, we can discuss the technical and experimental details of our work in subgroups of specialists, but also share the most current knowledge on problems in oilseed production with the specialists of the other sub-group. The result – we are double winners, as we can dwell on very detailed aspects of studies that interest us directly, without losing much of the general picture. As usual, the main crop to be discussed is oilseed rape (Brassica napus) – an amazingly versatile crop grown on all continents, from Europe through Asia to North America and Australia. Europe is still the world’s leader with 21.7 million tons harvested in 2015 representing nearly 70% of global production (EuroStat). However, the leading position may be lost, if we do not manage to counteract the yield losses due to increasing pest damages. This year entomologists will dwell on the increasing pressure on insecticidal active ingredients; on one hand the continued development of pest resistance to available compounds and on the other, revocation of the neonicotinoid seed treatments by the EU. Entomologists like to joke that pathologists don’t need to worry about clubroot if farmers live in a hotspot area for cabbage stem flea beetle, as these pests can completely devastate the crop before proper establishment. But it is no joke that many farmers (particularly in UK) are giving up growing oilseed rape due to these problems. We must work together to develop sustainable, alternative control strategies for insect pests of oilseeds that minimize insecticide use and reduce the risk of resistance. Current problems discussed by plant pathologists primarily concern clubroot of oilseed rape caused by the microorganism classified as belonging to the Kingdom of Rhizaria. Ever heard of this Kingdom? If not, please read in this volume of the IOBC Bulletin about the havoc it can cause. Problems with the stem canker of oilseed rape have partially been overcome by the introduction of the Rlm resistance genes and the current step is to combine them with quantitative resistance to biotic and abiotic stress. Also, new molecular techniques will be presented to enable quantification of the pathogens in plant tissues as well as in the soil. But the pathogens ‘never sleep’; new races, pathotypes, lineages as well as resistances to current chemistry and resistance genes are regularly found which pose new threats to oilseed rape production. Against this background, both sub-groups discuss methods for ecology-based IPM strategies that can be realized and that are currently viewed as a need, not just an option! This year we will also meet the newcomer to our group; hemp. Plant breeders obtained dioecious and monoecious hemps, free from hallucinogenic compounds, but producing big quantities of seeds with interesting oil composition. As usual, however, these oilseeds also have many enemies, among them insects, fungi, bacteria and viruses. And they are loved by birds! III Similar to our previous meetings, this meeting will include nearly 60 participants from 11 countries, including Austria, Croatia, Czech Republic, Denmark, Estonia, France, Germany, Poland, Sweden, Switzerland and the United Kingdom. So many people and countries, but we mostly know each other well. It is not an exaggeration to say we are one big family. As usual in any family, one can expect hot discussions and many different views on the same topic…. but this is why we meet! Surely, it will not be boring!

Damit ergibt sich, daß in der Zeit 1838 — 1990 im untersuchten Gebiet ca. 1 800 Käferarten registriert wurden. Nach der Veröffentlichung der ersten Ergänzung im Jahre 1989 mit dem Stand der faunistischen Erfassung bis zum 31. 12. 1986 kann nun die zweite Ergänzung der „Fauna Coleoptera des Kreises Altenburg“ vorgelegt werden. Ich halte es für sinnvoll, auch für die zweite Ergänzung die bisherige Form bcizubchaltcn. Wenn bei verschiedenen Arten die Fundjahre noch in die Zeit der vorangegangenen Zusammenstellungen gehören, ist das darin begründet, daß die Determination dieser Exemplare erst später erfolgte oder die Fundmeldungen vorher nicht bekannt waren. Wie bisher weisen die Abkürzungen im Anschluß an die Fundort-Angabe daraufhin, daß Erwin Naumann (N) oder U lrich Poller (P) diese Art nachwiesen. Gehen Fundnachweise auf andere Personen zurück, ist das namentlich oder in Fußnoten vermerkt. Zwei Kreuze (+ + ) weisen darauf hin, daß diese Art erstmals im Kreisgebiet nachgewiesen wurden.

SCHMIDT Abstract Two new species of Ground Beetles (Coleoptera: Carabidae: Platynini) are described: Anchomenus bellus sp.n. from southern and eastern Turkey, and A. alcedo sp.n. from northern Israel and Lebanon. In external characters they are very similar to the western Turkey endemic A. dohrnii FAIRMAIRE, 1866, but differ distinctly each in male genitalic characters. A third new species of Anchomenus BONELLI is described from eastern Afghanistan: A. kataevi sp.n. The relationships of the new species are briefly discussed, and a key to the Palaearctic representatives of the genus Anchomenus is pro- vided. Anchomenus dorsalis infuscatus CHEVROLAT, 1854, formerly considered a junior synonym of A. dorsalis PONTOPPIDAN, 1763, is here regarded as a good subspecies.

Cyril and Methodius University, Skopje, Macedonia 2 Macedonian Ecological Society, Skopje, Macedonia Received: 10.04.2014 Accepted/Published Online: 12.08.2015 Final Version: 07.04.2016 Abstract: The aim of this investigation was to analyze the effects of microhabitats and forest fragmentation on the composition and species abundance of a ground beetle community from three different beech forest patches on Mt. Osogovo (Macedonia), as well as to analyze the mobility (based on mark-recapture of individuals) and seasonal dynamics and sex ratio of the ground beetle community. The study site included three localities (A, B, C), one of them fragmented (A), with four microhabitats (open area, ecotone, forest stand, and forested corridor). Ground beetles were collected using pitfall traps during four sampling months (June–September 2009) that were operational for three continuous days per month. Species richness, abundance, diversity, homogeneity, and dominance were compared between the localities. Dissimilarities in carabid assemblages between localities and microhabitats were analyzed with Bray–Curtis UPGMA cluster analysis. In total 1320 carabid individuals belonging to 19 species were captured. The carabid assemblage structure of the continuous forest locality was substantially different from the other two smaller forest patches, indicating that microhabitat structure affects ground beetle communities through changes of species composition and richness.

Phytomyza linguae Lundqvist, 1947 is recorded as new to Finland. Keywords Checklist, Finland, Diptera, biodiversity, faunistics Introduction The Agromyzidae are called the leaf-miner or leaf-mining flies and not without reason, although a substantial fraction of the species feed as larvae on other parts of living plants. While Agromyzidae is traditionally placed in the superfamily Opomyzoidea, its exact relationships with other acalyptrate Diptera are poorly understood (see for example Winkler et al. 2010). Two subfamilies are recognised within the leaf-mining flies: Agromyzinae and Phytomyzinae. Both are now recognised as natural groups (Dempewolf 2005, Scheffer et al. 2007). Unfortunately the genera are not as well defined: at least Ophiomyia, Phy- toliriomyza and Aulagromyza are paraphyletic in DNA sequence analyses (see Scheffer et al.

Carabids, conservation, dispersal, forests, habitat fragmentation, habitat heterogeneity, metapopulations, species richness, generalists, specialists Abstract. I review the effects of habitat fragmentation on carabid beetles (Coleoptera, Carabidae) and examine whether the taxon could be used as an indicator of fragmentation. Related to this, I study the conservation needs of carabids. The reviewed studies showed that habitat fragmentation affects carabid assemblages. Many species that require habitat types found in interiors of frag­ ments are threatened by fragmentation. On the other hand, the species composition of small fragments of habitat (up to a few hec­ tares) is often altered by species invading from the surroundings. Recommendations for mitigating these adverse effects include maintenance of large habitat patches and connections between them. Furthermore, landscape homogenisation should be avoided by maintaining heterogeneity ofhabitat types. It appears that at least in the Northern Hemisphere there is enough data about carabids for them to be fruitfully used to signal changes in land use practices. Many carabid species have been classified as threatened. Mainte­ nance of the red-listed carabids in the landscape requires species-specific or assemblage-specific measures. INTRODUCTION HABITAT FRAGMENTATION AND CARABID ASSEMBLAGES Destruction and fragmentation of habitats, overkill, introduction of alien species, and cascading effects of Effects of fragmentation on carabid assemblages species extinctions have been labelled the “evil quartet”, Habitat fragmentation is the partitioning of a con­ i.e.

The morphological variability and different modes of life result from beetle ability to adapt to all kinds of habitats. Terrestrial and soil living forms dominate. Beetles undergo a complete metamorphosis and most species live in soil during at least one of the stages. They include predators, herbivores, parasites and sapro- phagans, playing a fairly significant role in nature and in man’s economy. Our knowledge of beetles, even of the common species, is insufficient. In spite of the fact that the beetle fauna of Central Europe has been studied relatively well, the knowledge accumulated is generally limited to the adults, while the immature stages have not been adequately studied.

Coleoptera, Carabidae, ectoparasitic fungi, Ascomycetes, Laboulbenia, microhabitat, overwintering sites Abstract. The prevalence of obligate parasitic fungi may depend partly on the environmental conditions prevailing in the habitats of their hosts. Ectoparasitic fungi of the order Laboulbeniales (Ascomycetes) infect arthropods and form thalli on the host’s body sur- face. Although several studies report the incidence of infection of certain host species by these fungi, quantitative data on laboulbe- nialean fungus-host arthropod interactions at the host assemblage level are rarely reported. To clarify the effects of host habitats on infection by ectoparasitic fungi, the incidence of infection by fungi of the genus Laboulbenia (Laboulbeniales) of overwintering carabid beetles (Coleoptera: Carabidae) in three habitats, a riverside (reeds and vines), a secondary forest and farmland (rice and vegetable fields), were compared in central Japan. Of the 531 adults of 53 carabid species (nine subfamilies) collected in the three habitats, a Laboulbenia infection of one, five and one species of the carabid subfamilies Pterostichinae, Harpalinae and Callistinae, respectively, was detected. Three species of fungus were identified: L. coneglanensis, L. pseudomasei and L. fasciculate. The inci- dence of infection by Laboulbenia was higher in the riverside habitat (8.97% of individuals; 14/156) than in the forest (0.93%; 2/214) and farmland (0%; 0/161) habitats.

  • Target-Site and Metabolic Resistance Against Λ-Cyhalothrin in Cabbage Stem Flea Beetles in Denmark
    Bulletin of Insectology 71 (1): 45-49, 2018 ISSN 1721-8861 Target-site and metabolic resistance against λ-cyhalothrin in cabbage stem flea beetles in Denmark Dorte H. HØJLAND, Michael KRISTENSEN Department of Agroecology, Aarhus University, Slagelse, Denmark Abstract The cabbage stem flea beetle, Psylliodes chrysocephala (L.) (Coleoptera Chrysomelidae) is a major pest of oilseed rape through- out Europe. Pyrethroids has been widely used for control of P. chrysocephala, but in recent years control failure has occurred, possibly due to resistance. Thirteen out of 15 populations collected in Denmark were susceptible to λ-cyhalothrin. Just two popu- lations, both from the south of Denmark had decreased susceptibility. The target site resistance allele, kdr, was found in a fre- quency from 0.00 to 0.76. There seemed to be a good relationship of the frequency of the target site mutation and resistance levels with some regional differences. Based on the data presented here target site mutation is a good indicator of decreased λ-cyhalothrin susceptibility. However, it is not the sole contributor to pyrethroid resistance in Danish P. chrysocephala, and the potential involvement of metabolic resistance should be investigated. Key words: Psylliodes chrysocephala, pyrethroid, insecticide resistance, kdr, knockdown resistance.
