Host Plants and Seasonal Presence of Dictyophara Europaea in the Vineyard Agro-Ecosystem
Bulletin of Insectology 61 (1): 199-200, 2008 ISSN 1721-8861 Host plants and seasonal presence of Dictyophara europaea in the vineyard agro-ecosystem Federico LESSIO, Alberto ALMA Di.Va.P.R.A., Entomologia e Zoologia applicate all’Ambiente “C. Vidano”, Facoltà di Agraria, Università di Torino, Italy Abstract Seasonal presence and host plants of Dictyophara europaea (L.), a candidate vector of phytoplasmas to grapevine, were studied in Piedmont during 2006 in different vine growing regions. Sampling consisted in net sweeping on different candidate host plants, and captures of adults with yellow sticky traps placed on grapevine. D. europaea nymphs and adults were collected on many weeds, showing how this planthopper should be considered a poly- phagous species, although Amaranthus retroflexus L. and Urtica dioica L. seem to be its preferred hosts, and may also bear phy- toplasmas. Larvae of Dryinidae were observed on almost 5% of collected individuals. The peak of adult presence was recorded in the middle of August, but few adults were captured on sticky traps placed on grapevine. Molecular analyses will be performed to detect the presence of phytoplasmas in captured individuals; however, given its scarce presence on grapevine, D. europaea does not seem capable to play a major role in the transmission of phytoplasmas to grapevine even if its vector ability were proved.

Background Information Phytoplasmas, formerly known as mycoplasma-like organisms (MLOs), are pleomorphic, cell wall-less bacteria with small genomes (530 to 1350 kbp) of low G + C content (23-29%). They belong to the class Mollicutes and are the putative causal agents of yellows diseases that affect at least 1,000 plant species worldwide (McCoy et al., 1989; Seemüller et al., 2002). These minute, endocellular prokaryotes colonize the phloem of their infected plant hosts as well as various tissues and organs of their respective insect vectors. Phytoplasmas are transmitted to plants during feeding activity by their vectors, primarily leafhoppers, planthoppers, and psyllids (IRPCM, 2004; Weintraub and Beanland, 2006). Although phytoplasmas cannot be routinely grown by laboratory culture in cell free media, they may be observed in infected plant or insect tissues by use of electron microscopy or detected by molecular assays incorporating antibodies or nucleic acids. Since biological and phenotypic properties in pure culture are unavailable as aids in their identification, analysis of 16S rRNA genes has been adopted instead as the major basis for phytoplasma taxonomy. -

Its earliest known member has been described from the Late Cretaceous (Santonian) amber of Taimyr and assigned to the extinct tribe Netutelini (Emeljanov, 1983). Szwedo (2008) described a monotypic genus from Baltic amber and placed it in a tribe of its own, Worskaitini, which he considered closely related to Netutelini. -

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. -

The following changes are proposed: Neonotostrophia nom. n. for Notostrophia Emeljanov (not Waterhouse); Emeljanovina nom. n. for Glochina Emeljanov (not Meigen); Neonotostrophia nigrosuturalis (Melichar, 1912) comb. n. from Notostrophia nigrosuturalis (Melichar, 1912) = Dictyophara nigrosuturalis Melichar, 1912 and Emeljanovina dixoni (Distant, 1906) comb. n. from Glochina dixoni (Distant, 1906) = Dictyophara dixoni Distant, 1906. Keywords Homoptera, Dictyopharidae, planthopper, homonym, replacement name Introduction The purpose of the present paper is to bring the taxonomy of planthoppers into accord- ance with the International Code of Zoological Nomenclature (1999). Two homonyms were discovered for genera names in Dictyopharidae (Hemiptera: Fulgoromorpha). In an effort to reduce homonyms in Fulgoromorpha, we propose two replacement names for these genera.

Population Status and Reproductive Biology of Clematis Morefieldii, a Federally Endangered Plant
POPULATION STATUS AND REPRODUCTIVE BIOLOGY OF CLEMATIS MOREFIELDII, A FEDERALLY ENDANGERED PLANT by Kyle Jordan Paris A thesis submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Master of Science Auburn, Alabama December 14, 2013 Cumberland Plateau, herbivory, insecticide, limestone outcrop endemic, reproductive attrition, seedling establishment Copyright 2013 by Kyle Jordan Paris Approved by Robert S. Boyd, Chair, Professor of Biological Sciences, Auburn University Kevin S. Burgess, Associate Professor of Biological Sciences, Columbus State University, GA Amy N. Wright, Professor of Horticulture, Auburn University Abstract Clematis morefieldii is a federally endangered, perennial climbing vine. It inhabits limestone drains and outcrops on the Cumberland Plateau escarpments of northeast Alabama and south-central Tennessee. The NatureServe network ranks this species as imperiled in Alabama and critically imperiled in Tennessee. Given its habitat specificity, localized distribution, and rarity, it is of considerable interest to the conservation community and to the organizations obligated to manage it. Since its discovery over 30 years ago, there has been no in depth study of this species and pertinent information for management is absent. The goal of this thesis is to investigate the condition of current populations, document the species’ biology and life history, and assess impacts of herbivory. To achieve this goal, a one-year population structure and herbivory survey, a four-year reproductive attrition study, and a three-year insecticide study were conducted between 2009-2012, sponsored, in part, by the U.S. Fish and Wildlife Service. The population structure and herbivory survey estimated range-wide population numbers, described proportions of life history stages in each population sampled, and evaluated the extent of vegetative herbivory in each sampled population across the range of C. -
Evolution of Delphacidae (Hemiptera: Fulgoroidea): Combined-Evidence Phylogenetics Reveals Importance of Grass Host Shifts
Systematic Entomology (2010), 35, 678–691 DOI: 10.1111/j.1365-3113.2010.00539.x Evolution of Delphacidae (Hemiptera: Fulgoroidea): combined-evidence phylogenetics reveals importance of grass host shifts JULIE M. URBAN1, CHARLES R. BARTLETT2 and J A S O N R . CRYAN1 1Research and Collections, Laboratory for Conservation and Evolutionary Genetics, New York State Museum, Albany, NY, U.S.A. and 2Department of Entomology and Wildlife Ecology, University of Delaware, Newark, DE, U.S.A. Abstract. The planthopper family Delphacidae is a speciose lineage of phloem- feeding insects, with many species considered as pests of economic significance on essential world food commodities (including rice, maize, wheat, barley and sugar cane). Despite their economic importance, evolutionary relationships among delphacids, particularly those within the speciose tribe Delphacini, are largely unknown. Presented here are the results of a phylogenetic investigation of Delphacidae based on DNA nucleotide sequence data from four genetic loci (18S rDNA, 28S rDNA, wingless and cytochrome oxidase I ) and 132 coded morphological characters. The resulting topologies are used to test the higher classification of Delphacidae and to examine evolutionary patterns in host–plant associations. Our results generally support the higher classifications of Delphacidae proposed by Asche, Emeljanov and Hamilton, and suggest that the rapid diversification of the Delphacini was associated with host shifts to, and within, Poaceae, and specifically from C3 to C4 grasses. Introduction infestations in 2009 reportedly occurring in Bangladesh, China, Malaysia, Philippines, Thailand and Vietnam (Heong, 2009). The insect family Delphacidae (Hemiptera: Fulgoroidea), Within Delphacidae, 85 species are recognized as economically including approximately 2100 described species, is the most significant pests, incurring damage to approximately 25 plant speciose and economically important of the ∼20 planthopper crops (Wilson & O’Brien, 1987; Wilson, 2005).
