Faunistic analysis of Gyponini (Cicadellidae: Iassinae: Gyponini), collected in plum orchards located in the municipality of Videira, Santa Catarina, Brazil.

Gyponini has a wide distribution in the Americas and high abundance in plum orchards in southern Brazil. However, there is not much information regarding the economic importance and potential as vectors of microorganisms for the culture of plum. The purpose of this study was to perform the faunistic analysis of Gyponini in two plum orchards, variety ?Letícia?. The orchards are located in the municipality of Videira, state of Santa Catarina, Brazil (orchard #1 - 27º03?18??S; 51º08?46??O, orchard #2 - 27º02?05??S; 51º08?57??O). Each area contains 1 hectare and plants aged 10 years. Sampling was carried out from December 2010 to December 2012 using yellow sticky cards (8.5 x 11.5 cm), installed in 10 equidistant points (35 x 35 m). At each point, two traps were installed and replaced monthly; low (B) at 0.5 m above the ground and high (A) at 1.7 m above the ground. Eleven species belonging to Gyponini were identified: Curtara sp. (13), C. samera (3), Gypona sp. (14), G. acuta (9), G. parvula (5), G. sellata (2), G. stalina (1), G. validana (1), Polana sp. (3), Reticana lineata (1) and Sordana sordida (1). A total of 53 individuals were collected in the orchards. The highest rate of capture has occurred in the trap B, totaling 31 specimens, and only 22 individuals on the trap A. The dominant species were Curtara sp., Gypona sp., G. acuta and G. parvula with respective frequencies of 24.53%, 26.43%, 17% and 9.43%. There was no occurrence of constant species, only accessory and accidental species. Curtara sp. and G. acuta were caught predominantly in the lower traps. G. parvula showed higher capture rate in traps located in the upper part of plant canopy and Gypona sp. showed a similar distribution among the different heights. It is emphasized that this collecting method allowed identifying the most active species in relation to the stratum of the culture, as well as the abundance of the group in the orchards

Comparative analysis of the capture of leafhoppers (Cicadellidae: Cicadellinae), for different strata in plum orchards in the municipality of Videira, Santa Catarina, Brazil.

Leafhoppers, belonging to Cicadellinae, are known as insect vectors of the bacterium Xylella fastidiosa, which is the cause of Plum Leaf Scald (PLS) disease. Within Cicadellinae, the tribes Cicadellini and Proconiini show conspicuous morphological features and different behavioral patterns. This study aimed to analyze the capture rate of Cicadellinae at higher and lower portion of the vegetative strata in two plum orchards variety ?Letícia?. The orchards (1 ha each, containing 10 years old plants) were located in the municipality of Videira, state of Santa Catarina, Brazil. Sampling was carried out from December 2010 to December 2012 using yellow sticky cards (8.5 x 11.5 cm), installed in 10 equidistant points (35 x 35 m). At each point, two traps were installed and replaced monthly; low (B) at 0.5 m above the ground and high (A) at 1.7 m above the ground. During the survey, 25 species were identified, included in 18 genera: Cicadellini - Bucephalogonia sp.; B. xanthophis; Caragonalia carminata; Diedrocephala sp.; D. variegata; Dilobopterus costalimai; D. dispar; Erythrogonia dorsalis; Hortensia similis; Macugonalia sp.; M. cavifrons; M. leucomelas; Pawiloma victima; Parathona gratiosa; Sibovia sagata; Spinagonalia rubrovittata; Tettisama quinquemaculata and Torresabela fairmairei; Proconiini - Aulacizes sp.; A. obsoleta; Homalodisca ignorata; Molomea personata; Oncometopia facialis; O. fusca and Phera carbonaria. Cicadellini had a capture rate of 86.48% in low traps, which were located in the lower stratum of the vegetation; this corresponds to the behavior observed in other studies. However, Proconiini had a capture rate equal to 73.48% in low traps and only 26.52% on traps located on the tree stratum of the orchard; this is different from what was found in other cultures already evaluated. The development of wild vegetation present in the orchards possibly plays a part in the occurrence of leafhoppers in the lower stratum

Place attachment in deprived neighbourhoods: The impacts of population turnover and social mix

This paper examines the determinants of individual place attachment, focussing in particular on differences between deprived and others neighbourhoods, and on the impacts of population turnover and social mix. It uses a multi-level modelling approach to take account of both individual- and neighbourhood-level determinants. Data are drawn from a large sample government survey, the Citizenship Survey 2005, to which a variety of neighbourhood-level data have been attached. The paper argues that attachment is significantly lower in more deprived neighbourhoods primarily because these areas have weaker social cohesion but that, in other respects, the drivers of attachment are the same. Turnover has modest direct impacts on attachment through its effect on social cohesion. Social mix has very limited impacts on attachment and the effects vary between social groups. In general, higher status or more dominant groups appear less tolerant of social mix

Uso da técnica de confusão sexual no manejo populacional da Cryptoblades gnidiella (Lepidoptera: Pyralidae) em videira.

O objetivo deste trabalho foi avaliar a eficiência da técnica de confusão sexual, com o feromônio sexual composto (Z)-11-hexadecenal (Z11-16: Ald) a 1,8% e (Z)-13-octadecenal (Z13-18: Ald) a 1,8%, no controle da traça-dos-cachos, Cryptoblabes gnidiella (Lepidoptera: Pyralidae), em cultivares de videiras (Vitis vinifera) destinadas à produção de vinhos. Os experimentos foram realizados em duas localidades na região do Vale do São Francisco, em áreas comerciais de produção de uva para processamento, com as cultivares Cabernet Sauvignon, Petit Verdot, Tempranillo e Chenin Blanc. Os tratamentos avaliados foram os seguintes: confusão sexual com uso de liberadores Splat ("specialized pheromone and lure application technology"), aplicados com pistola manual a 500 pontos ha1 (2 g por ponto); e testemunha sem aplicação. O efeito da técnica sobre os adultos de C. gnidiella foi avaliado com uso de armadilha tipo Delta, iscada em um septo com 2 g de feromônio sintético da mesma formulação. Os danos nos cachos foram avaliados à colheita. O uso da técnica de confusã
