These occasions have been very important moments of confrontation that have led to very important results in the protection of the vine, so much so that most of our results have been included in local, regional and national directives and legislations. The agro-ecosystem of the vineyard with its interactions, phytoseids as controllers of mite populations, the finalization of forecasting models for diseases, the determination of threshold levels and the practical and widespread use of mating disruption methods are some of the undeniable results that have turned viticulture into a practice that can be defined highly integrated, fully respecting the environment. All this has been obtained thanks to the collaboration of researchers from different countries, to the constant exchange of information. As a matter of fact the international group has worked in the interest of the European Viticulture sector, and remains an example for the researchers because is one of the most long-standing working group of the IOBC/wprs, and its scientific production is relevant and regularly published by the IOBC/wprs bulletins.

It is noteworthy that new topics as biodiversity and IPM applications have become more and more important, as well as the influence of the cultivation activities. It would be very difficult to remember all the people who have worked and coordinated this group, from MARC BAJLOD to AUGUSTIN SCHMIDT and ERNST BOLLER. Many of them i ii have left, retired or passed away. I would like to remember my friend JACQUES STOCKEL and professor MINOS MARTELLI and MARIO BAGGIOLINI, who died last summer; they have been, together with others, two of the founders of the group. Fig. 2. Number of papers presented in the different Meetings from 1999 to 2007 in comparison with the Meeting at Gargnano. Fig. 3. Number of researchers attending to the Meetings at: Firenze (122), Ponte de Lima (138), Volos (217) and Darfo-Boario Terme (82). iii In the Meeting room I see many new faces…..of young people. They are the future, and this continuous change can only be positive for the future. I also see new additions from other countries such as Israel, the USA and Hungary, which give us the possibility to exchange viticultural knowledge and practices from other countries. In Fig. 3 are represented, for each Country, the participants to the different Meetings. Now, I don't think I can say what subjects will be faced in the future, but surely bio- diversity, the climatic changes and the new defense perspectives are all aspects that will be studied, as well as how new diseases or insects must be faced and eradicated in the next years. I'm sure this group will be able to face the new problems and to propose innovative and suitable solutions maintaining the role of guide for plant/vine protection. I would like to thank the local organizers of this meeting. I wish you all a good and profitable work. I also want to offer my congratulations and wishes for a good job on Agnes Calonnec, recently elected as new group convenor, hoping that all the colleagues will continue to help her as they helped me in the last years in the group management. Finally I’d like to offer my gratitude to CESARE GESSLER, a friend that worked with me to keep in touch with the General IOBC Committee. As far as I'm concerned, I will remain a member of this group and I will be very happy to take part to the next IOBC meeting on IPM of grapevine, with my usual working enthusiasm, not forgetting to have a drink with old friends. Maybe the wine will help us to produce new good ideas! Who knows??!?

  • On the Evolution of the Tymbalian Tymbal Organ: Comment On
    Cicadina 18 (2019): 17-26 17 Response to “On the evolution of the tymbalian tymbal organ: Comment on “Planthopper bugs use a fast, cyclic elastic recoil mechanism for effective vibrational communication at small body size” by Davranoglou et al. 2019” Leonidas-Romanos Davranoglou1, Alice Cicirello, Beth Mortimer, Graham K. Taylor Zusammenfassung: Kommunikation über Vibrationssignale in der Gruppe der Spitzkopf- zikaden (Hemiptera: Fulgoromorpha) ist allgegenwärtig, doch war der zugrundeliegende Mechanismus bis zu einem kürzlich erschienenen Artikel von Davranoglou et al. (2019) un- bekannt. In diesem Beitrag werden die funktionelle Morphologie, die Biomechanik des Ver- haltens und die systematische Verbreitung eines weitverbreiteten Vibrationsmechanismus´ beschrieben, den die Autoren als Schnapporgan („snapping organ“) bezeichneten. Der Me- chanismus dieses Schnapporgans unterscheidet sich prinzipiell von den einzigen vergleich- baren Vibrationsorganen innerhalb der Hemipteren, nämlich den Trommelorganen (Tymbal) der Singzikaden (Cicadidae, Cicadomorpha). Kurz nach der Veröffentlichung argumentier- ten Hoch et al. (2019), dass es „unnötig, wenn nicht sogar irreführend“ wäre, diesen Mecha- nismus als „snapping organ“ zu bezeichnen und führten aus, dass dieses vielmehr als tym- balähnliches Trommelorgan mit Schnappmechanismus („tymbalian tymbal organ with snap- ping mechanism“) bezeichnet werden sollte. Diese Bezeichnung bezieht sich auf die „Tym- balia“-Hypothese von Wessel et al. (2014), der zufolge alle bekannten abdominalen Vibrati- onsorgane der Hemiptera Modifikationen eines abdominalen Vibrationsorgans darstellen, das im letzten gemeinsamen Vorfahren der Fulgoromorpha, Cicadomorpha und Heterop- terodea vor 300 Mio. Jahren vorhanden war. In unserem Beitrag zeigen wir, dass die Krite- rien, die Wessel et al (2014) verwendeten, um das tymbalähnliche Trommelorgan zu definie- ren, auf fehlerhaften segmentalen Zuordnungen der Schlüsselmuskulaturen beruhen. Die „Tymbalia“-Hypothese muss daher neu evaluiert werden.

The impact of climate change on biological phenology in the UK Tim Sparks1 & Humphrey Crick2 1 Faculty of Engineering and Computing, Coventry University, Priory Street, Coventry, CV1 5FB 2 Natural England, Eastbrook, Shaftesbury Road, Cambridge, CB2 8DR Email: [email protected]; [email protected] 1 Sparks Pheno logy Biodiversity Report Card paper 12 2015 Executive summary Phenology can be described as the study of the timing of recurring natural events. The UK has a long history of phenological recording, particularly of first and last dates, but systematic national recording schemes are able to provide information on the distributions of events. The majority of data concern spring phenology, autumn phenology is relatively under-recorded. The UK is not usually water-limited in spring and therefore the major driver of the timing of life cycles (phenology) in the UK is temperature [H]. Phenological responses to temperature vary between species [H] but climate change remains the major driver of changed phenology [M]. For some species, other factors may also be important, such as soil biota, nutrients and daylength [M]. Wherever data is collected the majority of evidence suggests that spring events have advanced [H]. Thus, data show advances in the timing of bird spring migration [H], short distance migrants responding more than long-distance migrants [H], of egg laying in birds [H], in the flowering and leafing of plants[H] (although annual species may be more responsive than perennial species [L]), in the emergence dates of various invertebrates (butterflies [H], moths [M], aphids [H], dragonflies [M], hoverflies [L], carabid beetles [M]), in the migration [M] and breeding [M] of amphibians, in the fruiting of spring fungi [M], in freshwater fish migration [L] and spawning [L], in freshwater plankton [M], in the breeding activity among ruminant mammals [L] and the questing behaviour of ticks [L].

ABDUL-NOUR Key-words: Homoptera, Auchenorrhyncha, Cicadellidae, biology, ecology, zoogeography, Lebanon, Near East, Middle East. Abstr‘aet: Up to now, 47 species of Auchenorrhyncha (among which only 24 species of Cicadellidae) were known in Lebanon. This work is the result of intensive collecting, trap­ ping, field observations and laboratory breeding carried on by the author since the beginning of 1983 , along with some observations and results of previous work (unpub­ lished data) already done between 1972 and 1975* 73 species of Cicadellidae are listed, 60 of them being new records for Lebanon. The oldest records on the Lebanese Auchenorrhyncha that were available to the author is the very curious book "Voyage Zoologique d 1 Henri GADEAU de KERVILLE en Syrie (avril-juin 1908)", published in 1926. In a delightful nineteenth century literary style,this eccentric gentleman describes his zoological journey in the mountains of Lebanon and in Syria, giving the complete list of the Arthropoda he collected and had them identified by specialists. Ln the chapter 170 Hemiptera, he points out that the identifications and descriptions of new species were made by Dr. G. HORVATH in 1911. Thirteen species of Auchenorrhyncha are mentionned as being collected in Lebanon (Beit-Mery, Broummana and Baalbeck). In NAST's check list (1972) some of them have been omitted from the Syro-lebanese region, while others are said to exist only in Syria.

E-mail: [email protected]; [email protected] 2corresponding author Abstract Two new genera and species of empoascine leafhoppers, Luodianasca recurvata and Treufalka lamellata are described from southern China. A key to these and other Empoascini genera from China is also provided. Key words: Auchenorrhyncha, Empoascini, Luodianasca gen. nov., Treufalka gen. nov., taxonomy, distribution Introduction The leafhopper tribe Empoascini, with more than 1000 described species worldwide, is a large group within the subfamily Typhlocybinae and can most readily be identified by the forewing lacking an appendix, hind- wing with all longitudinal veins ending at the submarginal vein, and the submarginal vein reaching but not exceeding the vein R+MP (Zhang, 1990). At present 65 genera have been recognized distributed worldwide. Many species of the group are major pests of crops, such as cotton, grape and eggplant (Oman 1949, Vidano 1962, Nielson 1968, Zhang 1990). The cotton leafhopper, Amrasca biguttula, is a destructive pest in southern China (Kuoh, 1966, Zhang 1990). The empoascine fauna of China remains inadequately studied, more than 100 species in 18 genera are known, mainly treated in the works of Matsumura (1931), Kuoh (1966), Zhang (1990) and Dworakowska (1982).

  • 1 Demographic Study of the Green Leafhopper, Empoasca Decipiens
    Appl. Ent. Phytopath. Vol. 77, No. 2, March 2010 Demographic study of the green leafhopper, Empoasca decipiens (Hemiptera: Cicadellidae) on four sugar beet cultivars A. A. Talebi 1∗, A. Izadpanah 1, S. Moharramipour 1, Y. Fathipour 1 and B. Naseri 2 1- Faculty of Agriculture, Tarbiat Modares University, Tehran 2- Faculty of Agriculture, University of Mohaghegh Ardabili, Ardabil (Received: July 2008; Accepted: May 2009) ABSTRACT The green leafhopper, Empoasca decipiens Paoli (Hemiptera: Cicadellidae) is one of pests of sugar beet, Beta vulgaris L. in Iran. In this research, life table, reproduction and population growth parameters of E. decipiens were studied on four sugar beet cultivars: Shirin, Rasool, PP8 and IC. The experiments were conducted in a growth chamber at temperature of 25±1 ºC, 50-60% RH and a photoperiod of 16:8 (L:D) h. The survival rate of individuals developed into adults from the initial cohort stage was estimated 0.78, 0.81, 0.78, and 0.76 on Shirin, Rasool, PP8 and IC, respectively. The life expectancy was 13.75, 14.89, 14.46 and 15.72 days, respectively at the first day of adult emergence. The highest gross and net fecundity rates were on IC and Shirin, respectively. Gross reproduction rate were 22.03, 20.07, 22.06 and 22.31 female per female per generation, on Shirin, Rasool, PP8 and IC, -1 respectively. Intrinsic rate of increase ( rm) were 0.099 and 0.104 (day ) on Shirin and IC, respectively. The mean generation time ( T), net reproduction rate ( R0), doubling time ( DT ) and finite rate of increase ( λ) on these cultivars were estimated by Jackknife method: 29.14- 31.75 days, 20.07-22.31 female per female per generation, 6.62-7.01 days, and 1.103-1.110 offspring per female per day, respectively.

A total of 46 species of Auchenorrhyncha are reported from the Maltese Islands. They belong to the following families: Cixiidae (3 species), Delphacidae (7 species), Meenoplidae (1 species), Dictyopharidae (1 species), Tettigometridae (2 species), Issidae (2 species), Cicadidae (1 species), Aphrophoridae (2 species) and Cicadellidae (27 species). Since the Auchenorrhyncha fauna of Malta was never studied as such, 40 species reported in this work represent new records for this country and of these, Tamaricella complicata, an eastern Mediterranean species, is confirmed for the European territory. One species, Balclutha brevis is an established alien associated with the invasive Fontain Grass, Pennisetum setaceum. From a biogeographical perspective, the most interesting species are represented by Falcidius ebejeri which is endemic to Malta and Tachycixius remanei, a sub-endemic species so far known only from Italy and Malta. Three species recorded from Malta in the Fauna Europaea database were not found during the present study. KEY WORDS. Malta, Mediterranean, Planthoppers, Leafhoppers, new records. INTRODUCTION The Auchenorrhyncha is represented by a large group of plant sap feeding insects commonly referred to as leafhoppers, planthoppers, cicadas, etc. They occur in all terrestrial ecosystems where plants are present. Some species can transmit plant pathogens (viruses, bacteria and phytoplasmas) and this is often a problem if the host-plant happens to be a cultivated plant.

  • Distribution, Food Plants and Control of Asymmetrasca Decedens (Paoli, 1932) (Hemiptera: Cicadellidae)
    DISTRIBUTION, FOOD PLANTS AND CONTROL OF ASYMMETRASCA DECEDENS (PAOLI, 1932) (HEMIPTERA: CICADELLIDAE) N. FREITAS 1 & D. AGUIN-POMBO 1, 2 With 3 figures and 1 table ABSTRACT. Asymmetrasca decedens is a polyphagous species and a pest of many cultivated plants. Although it is mainly distributed in the Mediterranean region, recently it has been reported also from Madeira Island. So far here it has been found mainly in southern coastal areas on a reduced number of plants; this suggests that the species might have been introduced recently. In Oceanic islands as Madeira free vacant niches and reduced competition are common features that can favour the establishment of invasive species. Thus, if this leafhopper were introduced recently, it would be expected to increase its food plant range and distribution subsequently. Although the flora of Madeira is different from that of the Mediterranean region, the potential risk of attacking new plants should be not underestimated. To become aware of which plants are more likely to be attacked in this new ecosystem, it is necessary to know the actual host plant range of this species. Because such data are greatly scattered, we compile here the published information on food plant associations, distribution and control. According to this information, A. decedens is widely distributed in the Palaearctic region and is associated with many cultivated plants. It has been recorded on sixty-one different plants species, of which 75% are present in Madeira. KEY WORDS: Hemiptera, leafhoppers, Asymmetrasca, Madeira, distribution, food plants, control. 1 Department of Biology, University of Madeira, Campus da Penteada, 9000-390 Funchal, Madeira, Portugal.
