E- mail: [email protected] Abstract: The first information about the Psylloidea in Madeira was based mainly on material collected by Prof. Håkan Lindberg, which included 6 species belonging to family Psyllidae and 3 to Triozidae. Since then little has been added to our knowledge. An updated checklist is presented in this work which includes new records. The new material was collected in several different types of vegetation including cultivated land, exotic forest, humid evergreen forest, and high altitude vegetation and contains species belonging to the genera Ctenarytaina, Euphyllura, Psylla and Trioza. General faunistic considerations are presented for each one of the species treated, including their host plants and geographical distribution. Key words: Psylloidea, Macaronesia, Madeira Island. Resumo: Psilas da Ilha da Madeira - Uma checklist actualizada, incluindo novas referências. Em meados dos anos setenta e com base em material colhido pelo Prof. Håkan Lindberg, M. M. Loginova publicou pela primeira vez informação sobre os Psylloidea da Madeira. Esta incluia 6 espécies pertencentes à família Psyllidae e 3 à Triozidae. Desde esta altura pouco foi adicionado ao nosso conhecimento sobre este grupo. No presente trabalho, é apresentada uma checklist actualizada, a qual inclui várias referências novas para a fauna da Madeira. Estas espécies, que abrangem os géneros Ctenarytaina, Euphyllura, Psylla e Trioza foram colhidas em variados tipos de vegetação, incluindo, zonas de agricultura, floresta exótica, laurisilva e vegetação de altitude. São também fornecidos dados para cada uma das especies tratadas, relativamente a aspectos da sua biologia, plantas hospedeiras e distribuição geográfica, com enfase para a Macaronesia. Palavras chave: Psylloidea, Macaronesia, Ilha da Madeira. Suplemento Nº 6 ao Boletim da SPEN (335-342), 1999 INTRODUCTION The first published survey of the psyllid fauna from the northern islands of Macaronesia was presented by LOGINOVA (1976). This was based on material from the collection of Prof. Håkan Lindberg, who visited the Canary and Madeira archipelagos several times between 1926-1963 and on specimens collected by Dr. Remane on Tenerife in 1954. In this paper Loginova refers 6 species of Psyllidae from Madeira, (describing 5 as new to science) and 3 species of Triozidae. More recently HODKINSON (1990) and CARVALHO & AGUIAR (1997) add another 2 species of Triozidae from Madeira. The present work adds 4 new records of Psyllidae and 2 new species of Triozidae. MATERIAL AND METHODS The new material was collected in different habitats and on a range of plants from coastal, low and medium altitude cultivated land and transitional vegetation, exotic forest, humid evergreen forest (Laurisilva) and high altitude shrub vegetation. Vouchers of all the studied samples are deposited on the insect collections of the Laboratório Agrícola da Madeira (ICLAM). They are either preserved in ethanol, or dried. Some material is deposited in the Natural History Museum (BMNH). In the check list the synonymy is that mentioned on the literature for material collected in Madeira. The data presented in Table 1 is arranged alphabetically by host plant and the distribution data are only for the Macaronesian islands. HOST PLANTS AND DISTRIBUTION On the coastal shrub and grassland of Madeira only two species are found, both feeding on Chenopodiaceae, these being Rhodochlanis salsolae (Lethierry) and Trioza chenopodii Reuter. The former, originally described by LOGINOVA (1972) as R. parvipunctatus, is present in the dry eastern peninsula and islets of Madeira, feeding on Suaeda vera. T. chenopodii must have a wider distribution on the island, since the host plants, Chenopodium album and C. murale are common and widespread weeds, along road sides and disturbed cultivated and waste lands. An Atriplex sp. is also mentioned by LOGINOVA (1976) as a host plant of T. chenopodii, collected in São Vicente in the north of the island. This is probably Atriplex prostrata which according to PRESS & SHORT (1994: 73) is “Rare, confined to sea-cliffs along the north coast of Madeira from São Jorge westwards” and is also the only Atriplex present on the north coast. Both R. salsolae and T. chenopodii are also recorded from Porto Santo. The nettle psyllid Trioza urticae (Linnaeus) was another psyllid recorded by LOGINOVA (1976), based only on one male and one female. Its present status is unknown on Madeira, even bearing in mind that one of its host plants, Urtica urens is fairly common on the island The citrus psylla, Trioza erytreae (Del Guercio) was identified for the first time in 1994 by the first author, from a localised area in the municipality of Ribeira Brava on the south coast, mainly on lemon (Citrus limon) and orange (Citrus sinensis). Since then T. erytreae has spread slowly to the whole area of that municipality and already entered Aguiar & Martin – Psyllids from Madeira Island. the municipality of Ponta do Sol to the west. T. erytreae causes the formation of pit- galls on the leaves of his host plants. A new record is the pear psylla, Psylla pyri (Linnaeus), collected abundantly on pear trees near the centre of Santana in the north of the island. In the description of Psylla atlantica, LOGINOVA (1976) states that its host plant is clearly the willow. We can now confirm that P. atlantica’s host plant, at least in Madeira, is Salix canariensis, a small tree common along streams and damp ravines in most parts of Madeira. In the areas of the island occupied by exotic introduced forest, mainly of Pinus , Acacia and Eucalyptus, was found the second of the new records, the introduced Australian species Ctenarytaina eucalypti (Maskell), feeding on Eucalyptus globulus. Observations show that this psyllid is common, as is its host plant, suggesting that its introduction may not be recent. The next five species can be found near or inside areas of humid laurel forest (laurisilva). These include two endemic species of the genus Arytainilla Loginova feeding on Leguminosae. LOGINOVA (1976) did not mention any host plant when she described A. incuba, and for A. umbonata only stated that it was collected on Leguminosae, but the collecting sites are outside the known laurisilva borders We can now at least confirm that A. incuba feeds on the endemic legume Teline maderensis, of a Genistinae genus not included on the list of Arytainilla hosts provided by HODKINSON & HOLLIS (1987). Another new record for Madeira is the species Euphyllura canariensis Loginova which feeds on Picconia excelsa, a macaronesian member of the Oleaceae, a rare laurisilva tree ocurring in north and centre of the island. The fourth new record, Psylla exima Loginova, feeds on another rare laurisilva tree, Rhamnus glandulosa (Rhamnaceae). At least 3 species of Trioza Förster were discovered in the laurisilva ecosystem. In the material collected by Prof. Lindberg, LOGINOVA (1976) identified Trioza alacris Flor, a psyllid that causes the formation of galls on the leaves of Laurus nobilis in many parts of the world. Much more recently HODKINSON (1990), based on further material collected in Tenerife and Madeira, found enough morphological peculiarities to describe this insect as a species distinct from T. alacris. He states that this new species, Trioza laurisilvae Hodkinson, “is primarily associated with the laurel forests of the canary Islands group. The host plant is unknown but is almost certainly one or more of the endemic Canary Islands laurels”. We confirm that in Madeira the main host of Trioza laurisilvae is Laurus azorica and probably the same is true for the Canary Islands. Recently two new species of the genus Trioza were found in the laurisilva, colonising another rare endemic tree, Pittosporum coriaceum (Pittosporaceae), locally called “mocano”. Apparently, only one of these species is responsible for the formation of pit-galls seen on the leaves of the host plant. These new species, referred to here as Trioza sp. 1 and Trioza sp. 2, are currently being described by the first senior author. The upland vegetation, on the limit of and above the laurel forest, is mainly composed of grazed grassland and communities of Erica arborea and Erica scoparia. These ericaceous shrubs are the host plants of the endemic psyllids Strophingia arborea Loginova and Strophingia fallax Loginova. On her original description of S. fallax, LOGINOVA (1976) was unable to give a complete description of the male genitalia Suplemento Nº 6 ao Boletim da SPEN (335-342), 1999 because the only male specimen was damaged. The male genitalia was later redescribed by HODKINSON (1981). All this information is summarised in Table 1.

Gardner The current Auckland City Council Proposed District Scheme lists two Picconia excelsa trees in Remuera at St Kentigern School and at 115 Victoria Avenue that are to be protected for their botanical (rarity) value. This species the Canary Islands olive is not mentioned in most horticultural works. It forms a tree of medium size heavy in foliage with the rough bark and crooked branching typical of its family. Sterile specimens have a deceptive likeness to those of Nestegis spp. even having a waxy bloom on the petioles — (like N. cunninghamii but not N. apetala) (Johnson 1957). The older AK material was first determined by Dr Peter Green of Kew. There are several other individuals in Auckland like the above of good size but almost certainly less than a hundred years old. There are trees at 2 Woodside Ave Mt Eden at 277 Mt Eden Rd and on a farmhouse drive in Ihumatao Rd; there is a AK specimen from the Wilson Home in Takapuna and until recently there was a tree in the crater of Mt St John. Perhaps the importation of Picconia might be the result of a nurserymans recognizing that Canary Islands species should flourish in what is literally the opposite side of the world.

This Psyllid, which was introduced into New Jersey from Bel- gium and which is well known and destructive in Europe, has al- ready been recorded as occuring in New Jersey (Weiss, Canadian Ent. Feb., 1917, pp. 73-75). D. L. Crawford in the Monthly Bulletin of the California State Commission of Horticulture Vol. I, No. 3, p. 86, gives an account of its presence in California together with suggestions for its control and also treats it in his M:onograph of the Psyllide of the New World, Bull. 85, U. S. N. 5/[. It occurs in New Jersey on bay trees which are kept either under glass all the year or out of doors during the summer and Under glass the remainder of the year. The following observations were made on trees kept outside during the summer months. Its presence on Bay (Laurus nobilis) can be readily detected by the curled, discolored, swollen, blistered leaves, usually at the tips of the branches, containing what appear to be whitish masses. Upon uncurling a leaf the nymphs are readily seen clothed in a white waxy secretion.

  • The Jumping Plant-Lice (Hemiptera: Psylloidea) of the Maltese Islands
    BULLETIN OF THE ENTOMOLOGICAL SOCIETY OF MALTA (2020) Vol. 11 : 103–117 DOI: 10.17387/BULLENTSOCMALTA.2020.18 The jumping plant-lice (Hemiptera: Psylloidea) of the Maltese Islands David MIFSUD* ABSTRACT. Twenty-one species of jumping plant-lice accommodated in five different families are here recorded from the Maltese Islands in an annotated checklist. The Aphalaridae is represented by four species (Agonoscena targionii (Lichtenstein), Blastopsylla occidentalis Taylor, Colposcenia aliena (Löw) and Glycaspis brimblecombei Moore), of which two (B. occidentalis and G. brimblecombei) are alien species originating from Australia. The Homotomidae is represented by Homotoma ficus (Linnaeus) and Macrohomotoma gladiata Kuwayama, the latter being an alien species originating from the Far East. The Liviidae is represented by Euphyllura olivina (Costa), Diaphorina lycii Loginova and Psyllopsis fraxinicola (Foerster). The Psyllidae is represented by Acizzia uncatoides (Ferris & Klyver), Cacopsylla myrthi (Puton) and C. pyri (Linnaeus), of which Acizzia uncatoides is an alien species originating from Australia. Finally, the most species-rich family is the Triozidae, represented by nine species (Bactericera albiventris (Foerster), B. crithmi (Löw), B. trigonica Hodkinson, Heterotrioza chenopodii (Reuter), Lauritrioza alacris (Flor), Trioza centranthi (Vallot), T. galii Foerster, T. kiefferi Giard and T. urticae (Linnaeus)). For each of the above species, collection data, distribution, host- plant data and other relevant information is provided. Lycium intricatum Boiss. is a new host-plant record for Diaphorina lycii, and Rhamnus lycioides subsp. oleoides (L.) Jahand. & Maire is a new host-plant record for Cacopsylla myrthi. A host- plant shift is documented for Bactericera crithmi, which alternates between Ferula melitensis Brullo et al. in winter and Crithmum maritimum L.

  • Laurisilva of Madeira Portugal
    LAURISILVA OF MADEIRA PORTUGAL The Laurisilva of Madeira is the largest surviving relict of a virtually extinct laurel forest type once widespread in Europe. It is still 90% primary forest and is a centre of plant diversity, containing a unique suite of rare and relict plants and animals, especially endemic bryophytes, ferns, vascular plants, animals such as the Madeiran long-toed pigeon and a very rich invertebrate fauna. COUNTRY Portugal NAME Laurisilva of Madeira NATURAL WORLD HERITAGE SITE 1999: Inscribed on the World Heritage List under Natural Criteria ix and x. STATEMENT OF OUTSTANDING UNIVERSAL VALUE The UNESCO World Heritage Committee adopted the following Statement of Outstanding Universal Value at the time of inscription: Brief Synthesis The Laurisilva of Madeira, within the Parque Natural da Madeira (Madeira Natural Park) conserves the largest surviving area of primary laurel forest or "laurisilva", a vegetation type that is now confined to the Azores, Madeira and the Canary Islands. These forests display a wealth of ecological niches, intact ecosystem processes, and play a predominant role in maintaining the hydrological balance on the Island of Madeira. The property has great importance for biodiversity conservation with at least 76 vascular plant species endemic to Madeira occurring in the property, together with a high number of endemic invertebrates and two endemic birds including the emblematic Madeiran Laurel Pigeon. Criterion (ix): The Laurisilva of Madeira is an outstanding relict of a previously widespread laurel forest type, which covered much of Southern Europe 15-40 million years ago. The forest of the property completely covers a series of very steep, V-shaped valleys leading from the plateau and east-west ridge in the centre of the island to the north coast.

  • Canary Islands Greentours Itinerary Botanical Birdwatching Holiday
    Canary Islands A Greentours Itinerary Days 1, 2 & 4 Montanas de Teno - Laurel Forests Rugged mountains are cut by deep valleys and massive cliffs plunge precipitously into the sea in the northwest of Tenerife. This is the sparsely populated Montanas de Teno and it has some of the best remaining Laurel Forests in the archipelago. A verdant landscape, it is fed by moist air from the Atlantic, and has a soft yet uncompromising beauty. El Fraille has one of the richest floras in the Canaries with over 300 species of flowering plant, including endemics such as the Centaurea canariensis, Limonium fruticans and Tolpis crassiuscula. Strange Sow-thistles form an important part of the flora of these islands - here there's locally common Sonchus radicatus and the almost tree-like Sonchus arboreus. Amongst Maytenus canariensis and Picconia excelsa shrubs bloom rare Dorycnium broussonetii and Marcetella moquiniana. In the Barranco de Masca we'll find enormous Aeonium pseudourbicum with the impressive spires of Echium virescens and on dry slopes amongst pretty Euphorbia atropurpurea we'll seek little endemic Orchis canariensis. The Euphorbia covered Punta de Teno is the most westerly point on the island and is a good place to observe seabirds such as the very common Cory's Shearwaters. Whales, dolphins and even sharks are frequently seen from here. Between the peaceful villages of Erjos and Masca lies an important remnant of Laurel forest, now protected as a reserve. We will wander along tracks through this unusual deep-green mossy forest looking for exotic and unusual species such as Habenaria tridactylites, a member of a large genus of orchids.

RESUMEN: Se examinó la fauna de isópodos en diferentes bosques de laurisilva de La Gomera, El Hierro y La Palma (Canarias Occidentales), con datos obtenidos de trampas pitfall y muestras de suelo, citándose un total de 11 especies. Las comunidades de especies de bosques de La Gomera y El Hierro por una parte, y las de La Palma por otra, fueron muy diferentes a pesar de la similitud de la estructura forestal, la vegetación arbórea y las condiciones climáticas en las tres islas. La especie nativa Porcellio meridionalis es dominante en La Gomera y El Hierro, y alcanza su mayor abundancia en localidades frescas y húmedas por encima de 1200 m s.n.m. En todas las localidades forestales de La Palma fue siempre dominante Armadillidium vulgare, a menudo acompañada por pequeños Trichoniscidae endogeos. Cinco de las especies mencionadas han sido introducidas en las islas por el hombre en fechas históricas. Esas especies invasoras dominan cuantitativamente en muchos sitios del estudio, con una media en la proporción de especímenes invasivos:nativos de 3,1:1 en trampas pitfall, y de 1,1:1 en muestras de suelo.
