Item Espécies de cigarrinhas em cultivo de café no município de Santa Teresa, Espírito Santo, Brasil (Hemiptera, Cicadellidae, Cicadellinae)(Museu de Zoologia da Universidade de São Paulo, 2015) Carvalho, Rachel A.; Lopes, Maridiesse M.; Rodrigues, Luiz G. N.Cicadellinae leafhoppers are important vectors of crop plants pathogens. In Brazil, one of these vectors is the bacterium Xylella fastidiosa, which infects citrus, coffee and plum. There is little information available on occurrence, distribution and biology of cicadellines in coffee. A list of 141 specimens, collected in alternate months, between June 2009 and April 2010, on a coffee plantation located in Santa Teresa Municipality, Espírito Santo State, Brazil, is presented. These specimens represent 16 genera and 21 species belonging to the two Cicadellinae tribes, Cicadellini and Proconiini. The genus Graphocephala is, for the first time, recorded from Brazil.Item Diet, microhabitat use, and thermal preferences of Ptychoglossus bicolor (Squamata: Gymnophthalmidae) in an organic coffee shade plantation in Colombia(Museu de Zoologia da Universidade de São Paulo, 2010) Anaya-Rojas, Jaime M.; Serrano-Cardozo, Víctor H.; Ramírez-Pinilla, Martha P.Ptychoglossus bicolor is a small gymnophthalmid lizard distributed in the Magdalena Valley of Colombia. We studied ecological features of diet, microhabitat use, and thermal preferences of a population found in an organic coffee shade plantation at the Cordillera Oriental of the Colombian Andes. The studied population had a diet composed predominantly of isopods. The Relative Importance Index of isopods was 98.8%; there were no significant monthly differences in the full stomach content and volume of isopods eaten during the sampling year, neither between rainy and dry seasons. A large number of lizards were found active in the leaf-litter, buried around coffee tree roots, and under or in rotting logs. Lizard body temperature was positively correlated with substrate temperature and air temperature; sex differences in body temperature were not significant. At the studied locality we did not find lizards out of the coffee fields. Our results suggested that these lizards successfully cope with the conditions offered by the organic coffee areas as a result of the cultivation system. Thus, this population might be vulnerable to any modification of the habitat that changes microhabitat availability and abundance of isopods.
