The former species is reinstated from synonymy of the latter one and is redescribed and illustrated based on specimens from Southeastern Brazil. The male and female genitalia are described for the fi rst time. The two species are similar morphologically, but they can be easily distinguished from each other, as well as from the other species of the genus, by their color patterns. > Key words Membracoidea, Aulacizes quadripunctata, leafhopper, sharpshooter, taxonomy, morphology, Brazil. 1.

Introduced Parasitic Wasps Could Control Glassy-Winged Sharpshooter

This article is part of the collected publications of California Agriculture. California Agriculture is archived by the eScholarship Repository of the California Digital Library. Abstract The glassy-winged sharpshooter (GWSS) is an introduced pest that spreads the bacterium Xylella fastidiosa, which causes a variety of diseases such as Pierce’s disease in grapevines and leaf scorch in oleanders. GWSS has been established in Southern California since about 1990 and has also successfully invaded French Polynesia, Hawaii and Easter Island. Researchers from UC, the U.S. Department of Agriculture and the California Department of Food and Agriculture have introduced parasitic wasps for the biological control of GWSS. Four parasitoids from the southeastern United States have been released and appear to be establishing in Southern California. Parasitoids from Argentina are also being evaluated in quarantine but have not yet been released.

E-mail: [email protected]; [email protected] 2 Corresponding author. ABSTRACT. The male of the leafhopper Deselvana falleni (Stål, 1858) is for the first time described and illustrated based on material from the state of Rio de Janeiro, Brazil. Notes comparing D. falleni to other species of Deselvana Young, 1968 are given. Males and females of D. falleni can be recognized by the dark brown to black dorsum with four well-defined yellow maculae on each forewing, two on clavus and two on corium. The sexual dimorphism of color found in other Deselvana species was not observed in D. falleni. KEY WORDS. Auchenorrhyncha; male genitalia; Membracoidea; sharpshooter; taxonomy.

Observations of Acoustic Signaling in Three Sharpshooters: Homalodisca Vitripennis, Homalodisca Liturata, and Graphocephala Atropunctata (Hemiptera: Cicadellidae)
BEHAVIOR Observations of Acoustic Signaling in Three Sharpshooters: Homalodisca vitripennis, Homalodisca liturata, and Graphocephala atropunctata (Hemiptera: Cicadellidae) 1 2,3 2 DIANA M. PERCY, ELIZABETH A. BOYD, AND MARK S. HODDLE Ann. Entomol. Soc. Am. 101(1): 253Ð259 (2008) ABSTRACT Observations and comparative data are presented on the acoustic signals of three sharpshooter (Hemiptera: Auchenorrhyncha: Cicadellidae: Cicadellinae) species native to North America. The acoustic signals of the glassy-winged sharpshooter, Homalodisca vitripennis (Germar), native to the southeastern United States, are compared with two smaller sharpshooters native to the western United States, Homalodisca liturata Ball and blue-green sharpshooter, Graphocephala at- ropunctata (Signoret). Each sharpshooter is a known vector of the plant pathogenic bacterium Xylella fastidiosa Wells et al. Male acoustic signals from all three species and female signals from H. liturata and G. atropunctata were recorded from host plant substrates. The H. vitripennis calls were recorded in the evening and morning, whereas H. liturata and G. atropunctata were recorded in the afternoon. Each species has a characteristic acoustic signal of which the male call structure is most complex in H. vitripennis and simplest in H. liturata. MaleÐfemale acoustic duets in H. liturata and G. atropunctata were recorded, and distinct differences were found in the reply latencies between male and female calls in these species.

ABSTRACT: Although Graphocephala atropunctata (Signoret) (Hemiptera: Cicadellidae) is the native blue-green sharpshooter, BGSS, which has been a major vector of Pierce’s disease in vineyards in California for nearly a century, only recently has any genomic information become available. Due to the importance of the BGSS as the principal native vector of Pierce’s disease, we chose to examine the biology of the BGSS using a genomics approach. A cDNA library was made from adult BGSS, and 8,160 expressed sequence tags, ESTs, were produced. After quality scoring 6,836 sequences underwent assembly which produced a set of 1,915 sequences that putatively represented distinct transcripts. Initial annotation of this dataset identified 44 putative protein sequences were characterized through in silico analyses, and published in the NCBI database (Accession numbers are listed in Table 1). BLASTX analysis identified 10 significant homology matches to heat shock proteins, HSP, which are the focus of this study due to their overall importance and functions in maintaining protein integrity and activity during stressful conditions, such as extreme heat, cold, drought or crowding. -

Osbeck no Rio Grande do Sul RESUMO - Brocossomos são corpos ultramicroscópicos, reticulados, produzidos pelos tubos de Malpighi das cigarrinhas. São geralmente esféricos (brocossomos de tegumento) ou alongados (brocossomos de ovos). Neste estudo, as espécies de Proconiini foram identificadas de acordo com seus brocossomos de ovos. As características e uma chave para a identificação dos brocossomos também foram discutidas. Os espécimes foram coletados em nove pomares de Citrus sinensis (‘Valencia’), com o uso da armadilha adesiva de cor amarela. Os pomares estão localizados em sete municípios do Rio Grande do Sul: Tenente Portela, Ijuí, Jaguari, Harmonia, Taquari, Montenegro e Pelotas. Os dados foram coletados de outubro de 1999 a dezembro de 2000 e de outubro de 2001 a março de 2002. Foram identificadas sete espécies capazes de produzir brocossomos de ovos: Acrogonia citrina Marucci & Cavichioli, Homalodisca ignorata Melichar, Molomea consolida Shröder, Molomea lineiceps Young, Molomea magna (Walker), Oncometopia facialis (Signoret), e Oncometopia fusca Melichar. -
