Arboridia erecta (Ribaut, 1931) (Hemiptera, Cicadellidae), a new leafhopper to the fauna of the Iberian Peninsula, and data on the distribution of Arboridia parvula (Boheman, 1845)

The genus Arboridia comprises about fifteen species in Europe. Of these, only two species, A parvula and A. ribauti, had been recorded to Spain. This work reports Arboridia erecta for the first to the Iberian Peninsula. Food-plant associations, preferable habitats and data on distribution on the Northwest of Spain are provided for A. parvula and A. erecta.El género Arboridia comprende alrededor de quince especies en Europa. Sólo dos de ellas: A. parvula y A. ribauti, habían sido citadas para España. En este trabajo se cita por vez primera la presencia de Arboridia erecta en la Península Ibérica. Para esta especie y para A. parvula se dan datos sobre las plantas nutricias, hábitats preferenciales y distribución en el noroeste de España.info:eu-repo/semantics/publishedVersio

Validation of the faunistic data on the genus Alebra Fieber, 1872 (Hemiptera, Cicadellidae) in the Iberian Peninsula and Madeira

Identification of Alebra leafhoppers is difficult because most species do not show specific differences in male genital structures. Colour pattern and host plant associations, the characters traditionally used in the recognition of these species, show considerable intraspecific variation. In the last decade, it was proved that the shape of male abdominal apodemes is the most reliable morphological character to separate species of this genus, and since then, some species have been splitted in two. To untangling the systematics of the European species it urges to revise data on host plants and distribution. For the Iberian Peninsula the actual species number was still uncertain because the taxonomic value of apodemes in Alebra was unknown when the faunistic records on this region were published. In this work it was analysed material from Spain, Portugal and the island of Madeira and three species were identified: A. albostriella (Fallén, 1826), A. coryli Le Quesne, 1976, new to the Iberian peninsula, and A. viridis Rey, 1894 sensu Gillham 1991, recorded for the first time to the fauna of Madeira and Spain.La identificación de cigarrillas del género Alebra es difícil porque la mayoría de las especies no presentan diferencias específicas en las estructuras genitales de los machos. Los patrones de color y la asociación a sus plantas huéspedes, caracteres tradicionalmente utilizados en la separación de estas especies, muestran una considerable variación intraespecífica. En la última década, se ha probado que la forma de los apodemas abdominales de los machos es el carácter morfológico más fiable para separar las especies de este género, y desde entonces, algunas especies han sido separadas en dos. Para esclarecer la sistemática de las especies europeas de este género, es necesario hacer una revisión urgente de los datos existentes sobre sus plantas huéspedes y distribución. En la Península Ibérica el número real de especies conocidas todavía era incierto porque el valor taxonómico de los apodemas en Alebra era desconocido cuando fueron publicados los datos faunísticos sobre esta región. En este trabajo se ha estudiado material de España, Portugal y la isla de Madeira y han sido identificadas tres especies: A. albostriella (Fallén, 1826), A. coryli Le Quesne, 1976, nueva cita para la Península Ibérica, y A. viridis Rey, 1897 sensu Gillham 1991, referida por primera vez para la fauna de Madeira y España.info:eu-repo/semantics/publishedVersio

Hauptidia lapidicola (Vidano 1964), first record for Spain and data on the Iberian distribution of Hauptidia maroccana (Melichar 1907)(Hemiptera: Cicadellidae)

Species of the genus Hauptidia are associated to herbaceous plants. In Spain only two species of this genus are known: H. distinguenda (Kirschbaum, 1868) and H. maroccana (Melichar, 1907). In the study of material from northern and southern Spain, a little known species was found: H. lapidicola (Vidano, 1964). This leafhopper, found so far only in Portugal and Italy, is a new record for the Spanish fauna. Data on distribution, ecology and host plants for this species and Hauptidia maroccana are given in this work.: Las especies del género Hauptidia se encuentran asociadas a plantas herbáceas. En España se conocen dos especies: H. distinguenda (Kirschbaum, 1868) y H. maroccana (Melichar, 1907). Estudiando material procedente del norte y sur de España se encontró una especie poco conocida, H. lapidicola (Vidano, 1964). Esta cigarrilla sólo se conocía de Portugal e Italia y se cita por primera vez para la fauna española. En este trabajo se aportan datos sobre la distribución, ecología y plantas huéspedes de Hauptida maroccana y H. lapidicola.info:eu-repo/semantics/publishedVersio

Cuatro cigarrillas de la subfamilia Typhlocybinae (Homoptera, Cicadellidae) nuevas para la fauna española

Los Tiflocíbinos son un grupo de insectos fitófagos poco conocidos en la Península Ibérica. Hasta ahora han sido citadas solamente unas setenta especies de cigarrillas. Del estudio del material recogido principalmente en el noroeste de España han resultado cua tro cigarrillas nuevas para la fauna española pertenecientes a la tribu Typhlocibini. De estas, dos especies son nuevas para la Península: Wagneripteryx germari (Zetterstedt, 1840) y Edwardsiana hippocastani (Edwards, 1888); las otras dos: Eurhadina ribauti Wagner, 1935 y Eupteryx filicum (Newman, 1853), son dos citas nuevas para España. Para cada especie se incluye información sobre su distribución, biología y plantas nutricias.Typhlocibid leafhoppers are a group of phytophagous insects little known in the Ibe rian Peninsula. Until now only about seventy leafhopper species have been recorded. After the study of material collected mainly from the northwest of Spain, four new spe cies records belonging to the tribe Typhlocibini were found. Of those, two species are new to the Iberian Peninsula: Wagneripteryx germari (Zetterstedt, 1840) and Edward siana hippocastani (Edwards, 1888), the other two: Eupteryx filicum (Newman, 1853) and Eurhadina ribauti Wagner, 1935, are new records to Spain. For each species infor mation on distribution, biology and food plants is included.info:eu-repo/semantics/publishedVersio

A new species of the planthopper genus Conosimus associated with an endemic shrub in southern Spain

The poorly-known genus Conosimus Mulsant et Rey, 1855 (Hemiptera: Fulgoroidea: Issidae) includes six species and is briefly reviewed. Adults and fifth instars of a new species, Conosimus baenai n. sp., are described and compared with other species in the genus. The new species is associated with an endemic shrub, Echinospartum boissieri, in Jaen, Spain, in the south of the Iberian Peninsula, one of the richest botanical areas of the Mediterranean Basin.info:eu-repo/semantics/publishedVersio

First report of Scaphoideus titanus for Madeira Island

This is the first report of Scaphoideus titanus, the main vector of flavescence dor ee, for Madeira (Portugal) and also for Macaronesia. This new record currently represents its southernmost occurrence in Europe. This leafhopper is present in most of the primary wine production regions in the north of Madeira island. There were no symptoms of flavescence dor ee disease during the monitoring period from 2010 to 2017. The ability of S. titanus to survive in regions with a subtropical climate suggests that it may also live in the most meridional areas of the Mediterranean region where, until now, it has been absent.info:eu-repo/semantics/publishedVersio

Bionomics and taxonomy of leafhopper Sophonia orientalis (Homoptera: Cicadellidae), a Pacific pest species in the Macaronesian Archipelagos

The leafhopper Sophonia orientalis (Matsumura) (Homoptera: Cicadellidae) is native to Asia, but it has been recently introduced to the Hawaii Archipelago, CA and French Polynesia. Although this extremely polyphagous species is considered to be a threat to all native plants of Hawaii and to many economically important cropping cultures, its taxonomy remains obscure. Most literature referred to this species as Sophonia rufofascia (Kuoh & Kuoh), but recently it has been shown that previous records of this species correspond to S. orientalis. In this study, S. orientalis is recorded from northeastern Atlantic archipelagos of Madeira and Canaries, with the Þrst collection made in 2000 representing the Þrst record of this species for Macaronesia. Diagnosis of the species together with information on the karyotype and structure of testes and ovaries is given. The number of chromosomes is 2n 16 X0 (males) and 2n 16 XX (females), and each testis and ovaryis composed of six follicles and six ovarioles, respectively. In Madeira, S. orientalis was found on 28 plant species, including native and endemic plants, but it also was associated with important crops such as vineyards. The presence of adults and nymphs during most of the year suggests that this species has several annual generations. Owing to the suitable climate and the presence of a great number of host plants, its potential for detrimental effects to Madeira ecosystems is considered to be great, and the proximity of Madeira and Canary Islands to the European land mass suggests that this pest may spread.info:eu-repo/semantics/publishedVersio

The INTERFRUTA II project and the study of phytossanitary problems that affect Azorean fruit orchards and vineyards

The INTERFRUTA project is financed by the European Commission Interreg III-B Programme and was developed for the islands of “Madeira”, “Tenerife” and “Terceira”, for the improvement of fruit and vineyard production in these three Atlantic regions. The project goal is a better knowledge of the phytossanitary problems that affect apples, bananas, chestnut and vineyards, applying methods that will contribute to solutions based on the survey of key pests, diseases and beneficial organisms. In the three fruit crops and vineyards analyzed, the methodology used was mainly direct observation of predefined parts of each plant (such as leaves and flowers) on which pests might be expected to occur. The key pest C. capitata was monitored as adults using sexual lures in a net of traps around the island of “Terceira” up to 200 meters altitude. The beneficial insect survey was conducted using the beating technique. For diseases, a direct sampling was carried out by the observation of 10 % of the plants in each orchard or vineyard plot looking for visible symptoms. In apples and vineyards, flowers and branches were collected and tested for microorganisms using serologic and molecular techniques (Elisa and PCR). In banana plantations, the most damaging pests were banana weevil, thrips and a fungi complex that causes symptoms similar to Fusarium wilt. In chestnut, the pest that causes the most severe damage, affecting around 40 % of the nuts produced, is the Chestnut tortrix, but there were some difficulties in identifying which of the three known species was present in the Azores islands. In vineyards, diseases that are most frequent and important include grapevine downy mildew, powdery mildew and Botrytis. Invertebrate pests included grape leafhoppers, thrips and eriophyid mites. The European vine moth was also surveyed but none were found and is still not present. In apple orchards the most important problems were thrips, mites, oriental fruit moth and codling moth. Anarsia lineatella Zeller, the peach twig borer, was not detected and new Eriophyid species have been recorded for the first time in the Azores as a result of the surveys. With the information collected it was possible to create a phytossanitary diagnostic database for the Macaronesian islands (PROFITOMAC) on the project internet pages (www.interfruta.uac.pt), to help users to identify problems that affect the studied cultures
