The programme for this meeting is exceptionally rich and diverse and contains many interesting and exciting contributions. The numbers of offered oral and poster presentations (>200) is quite exceptional and well beyond our expectations. It demonstrates that Integrated Plant Protection in Fruit Crops remains an area of strong interest in the WPRS and beyond. We greatly appreciate the strong representation at the conference by delegates from the USA and Canada. We are sorry that we have not been able to accommodate all the offered oral papers in the programme. This has meant that we have requested >30 offered oral papers to be presented as posters. Furthermore, the number of posters is so great that 2 separate poster sessions are necessary. This is the 4 yearly meeting of our whole IOBC Working Group which comprises 5 sub- groups (pome fruit arthropods, pome fruit diseases, soft fruits, stone fruits and IFP guidelines). The decision to have parallel sessions for pests and diseases was taken to ensure that both entomologists and pathologists attended this conference. We hope the arrangement will be successful and that moderators and speakers will adhere strictly to the timetable to allow delegates to move between sessions. Our working group, formerly named the ‘Orchards Working Group’ is near to celebrating its 50th anniversary. Our group was a pioneer in Integrated Pest and Disease Management and has come a long way from its historical roots. We welcome Ernst Boller, Honorary member of the IOBC, and a person with a strong interest in and with good links with our past, who has kindly agreed to give a historical review of our Working Group’s origins, founder members and activities. The IOBC council has provided substantive funds to support this conference and we have used these funds mainly to support the attendance of 8 students and young persons starting their career at this conference who otherwise would have been unlikely to attend. We welcome them and hope this conference will cement their interest in our subject. Finally, we are especially indebted to our colleagues from INRA Avignon who have agreed to host this conference. We extend our grateful thanks to all our French hosts. And we wish you all a very fruitful, interesting and memorable conference Jerry Cross (convenor), Claudio Ioriatti, Christian Linder, Fabio Molinari, Carlo Malavolta, Jesus Avilla, Arne Stensvand, Benoît Sauphanor. Conference scientific committee IFP 2008 – Avignon, France – October 27-30, 2008 3 Proceedings and publication Two options of publication of the communications will be offered, ie the IOBC bulletin or a special issue of the refereed international journal Agriculture Ecosystems and Environment. The IOBC bulletin is the usual support for publishing the proceedings of the working group meetings, study group meetings and commission activities. The guidelines for the manuscripts are available at http://www.iobc-wprs.org/pub/. The length of a manuscript will be limited to 4 pages; the deadline for submission is on 31 January 2009. In addition, all the abstracts of the oral communications and posters that will have been presented at IFP 2008 will be available on the open archives of INRA, with author and key word indexation, and the full texts distributed as pdf files. As an example, see the proceedings of the last EUCARPIA International Meeting on Cucurbitaceae (Avignon 21-24 May 2008) at https://w3.avignon.inra.fr/dspace/handle/2174/164 Agriculture Ecosystems and Environment (AEE), as a special

  • Flight Pattern of Archips Podana (Lep.: Tortricidae) Based on Data from Pheromone Traps
    Plant Protect. Sci. Vol. 40, No. 3: 75–81 Flight Pattern of Archips podana (Lep.: Tortricidae) Based on Data from Pheromone Traps J���� STARÁ and F�������� KOCOUREK Department of Entomology, Division of Plant Medicine, Research Institute of Crop Production, Prague-Ruzyně, Czech Republic Abstract S���� J., K������� F. (2004): Flight pattern of Archips podana (Lep.: Tortricidae) based on data from pheromone traps. Plant Protect. Sci., 40: 75–81. In 9 years of the period 1993–1999 and 2001–2003 the flight activity of Archips podana was investigated by pherom- one traps placed in four apple orchards in Central and East Bohemia. The cumulative catches of A. podana males were plotted against time of the catch expressed in sum of degree-days (DD) above 10°C and approximated by Richards’ function. Common parameters of Richards’ function could be found for the overwintering generation of A. podana from all localities. The beginning, peak and end of flight activity of the overwintering generation of the A. podana population in Central and East Bohemia can be predicted by use of DD. Archips podana is usually bivoltine in the Czech Republic, rarely univoltine in cold years or cold localities. Construct the flight pattern of the summer generation could of A. podana not be constructed, because the course of flight of this generation in dependence on DD differed significantly in particular years and localities. Keywords: Archips podana; fruit tree tortrix moth; apple orchards; flight activity; monitoring; pheromone traps; flight pa�ern; degree-days� The fruit tree tortrix moth, Archips podana (Scopoli, generation may occur. In southern areas the species 1763), is a polyphagous species and widely distrib- is bivoltine (V�� ��� G���� & E������� 1991).

Between 2004 and 2013 Csalomon type pheromone traps were operating in Bodrogkisfalud (48°10’N; 21°21E; Borsod-Abaúj- Zemplén County, Hungary, Europe). The data were processed of following species: Spotted Tentiform Leafminer (Phyllonorycter blancardella Fabricius, 1781), Hawthorn Red Midged Moth (Phyllonorycter corylifoliella Hübner, 1796), Peach Twig Borer (Anarsia lineatella Zeller, 1839), European Vine Moth (Lobesia botrana Denis et Schiffermüller, 1775), Plum Fruit Moth (Grapholita funebrana Treitschke, 1846), Oriental Fruit Moth (Grapholita molesta Busck, 1916) and Codling Moth (Cydia pomonella Linnaeus, 1758). The relation is linear, logarithmic and polynomial functions can be characterized. Keywords: Microlepidoptera, pests, pheromone traps, air pollution 1. INTRODUCTION Since the last century, air pollution has become a major environmental problem, mostly over large cities and industrial areas (Cassiani et al. 2013). It is natural that the air pollutant chemicals influence the life phenomena of insects, such as flight activity as well.

  • New Apple Pest, Hedya Nubiferana (Haworth), Discovered in Ohio1
    BRIEF NOTE New Apple Pest, Hedya nubiferana (Haworth), Discovered in Ohio1 ROY W. RINGS, Department of Entomology, Ohio Agricultural Research and Development Center, The Ohio State University, Wooster, OH 44691 ABSTRACT. The green budworm, Hedya nubiferana (Haworth), was collected in Ohio for the first time in 1991- A total of five specimens was collected at three sites in Portage County, OH. The collection of the green budworm at these widespread localities in Portage County in such numbers indicates that this potential pest species is now well established in Ohio, at least in the northeastern part. The identification of this species was made by Dr. William E. Miller, Department of Entomology, University of Minnesota, St. Paul, MN. Further studies in unsprayed, abandoned orchards and arboretums are suggested to more accurately determine the geographical distribution of this new species in Ohio. OHIO J.

Christian Schmidt Æ Jennifer Derhousoff Æ John A. McLean Æ Leland M. Humble Received: 3 November 2008 / Accepted: 18 June 2009 Ó Springer Science+Business Media B.V. 2009 Abstract To facilitate future assessments of diversity following disturbance events, we conducted a first level inventory of nocturnal Lepidoptera in Stanley Park, Vancouver, Canada. To aid the considerable task, we employed high-throughput DNA barcoding for the rough sorting of all material and for tentative species identifications, where possible. We report the preliminary species list of 190, the detection of four new exotic species (Argyresthia pruniella, Dichelia histrionana, Paraswammerdamia lutarea, and Prays fraxinella), and the potential discovery of two cryptic species. We describe the magnitude of assistance that barcoding presents for faunal inventories, from reducing specialist time to facilitating the detection of native and exotic species at low density.

  • Towards Classical Biological Control of Leek Moth
    ____________________________________________________________________________ Ateyyat This project seeks to provide greater coherence for the biocontrol knowledge system for regulators and researchers; create an open access information source for biocontrol re- search of agricultural pests in California, which will stimulate greater international knowl- edge sharing about agricultural pests in Mediterranean climates; and facilitate the exchange of information through a cyberinfrastructure among government regulators, and biocontrol entomologists and practitioners. It seeks broader impacts through: the uploading of previ- ously unavailable data being made openly accessible; the stimulation of greater interaction between the biological control regulation, research, and practitioner community in selected Mediterranean regions; the provision of more coherent and useful information to enhance regulatory decisions by public agency scientists; a partnership with the IOBC to facilitate international data sharing; and progress toward the ultimate goal of increasing the viability of biocontrol as a reduced risk pest control strategy.

  • Pests of Apple Leaf and Flower Buds in the Region of East Sarajevo
    IV International Symposium „Agrosym 2013“ 10.7251/AGSY1303546T PESTS OF APPLE LEAF AND FLOWER BUDS IN THE REGION OF EAST SARAJEVO Dejana TESANOVIC1*, Radoslava SPASIC2 1 Faculty of Agriculture, University of East Sarajevo, Bosnia and Herzegovina 2University of Belgrade, Faculty of Agriculture, Belgrade, Serbia *(Corresponding author: [email protected]) Abstract Insect species that feed with leaf and flower buds of apple are significant pests in all areas where this kind of fruit-trees is cultivated. Feeding with buds as imago and/or larvae these insects make damages manifesting in buds drying, disturbing normal development of leaves and flowers, reduction in the yield and quality of fruits. Exeminations were carried out in apple orchards in three locations on the region of East Sarajevo. Two extensive plantations over 40 years old were situated in the localities of Kasindo and Pale, while one intensive and youngish orchard with sorts Idared, Jonagold and Gold Delicious, was in the locality of Kula. Presence and harmfulness of buds pests was observed in the period of 2007- 2008. Seven species of harmful insects have been reared and determined on apple leaf and flower buds. Six Lepidopterous species were from the families Tortricidae and Geometridae, and one Coleopterous species was from the family of Curculionidae. Torticidae was represented with four species: Hedya nubiferana Haworth, Spilonota (Tmetocera) ocellana Fab., Archips podana Scopoli and Pandemis heperana Den.et Schiff. Two Geometrid species were Hibernia defoliaria Clerck and Cheimatobia brummata Linne. Only one beetle from the family Curculionidae was Anthonomus pomorum Linne. In extensive plantations the most numerous species on leaf buds during both years was Ch.
