Grapevine degeneration in grapevines caused by Grapevine fanleaf virus (GFLV) has been documented in many viticultural regions worldwide (Andret-Link et al. 2004). It is one of the major economically important virus diseases affecting the longevity of grapevines and reducing the fruit yield and fruit quality. Infected grapevines show a range of foliar symptoms consisting of leaf deformation, ye...
Virus infection in Vitis vinifera negatively impacts vineyard production and grape quality. Examples are grapevine leafroll-associated viruses (GLRaVs) rupestris stem pitting-associated (GRSPaV). We investigated transient fluorescence of chlorophyll a leaves Cabernet-Sauvignon, the primary red cultivar planted Chile, using OJIV test. First, we evaluated productive grapevines throughout their de...
Linepithema micans (Forel) (Hymenoptera: Formicidae) is the main ant species responsible for the spread of Eurhizococcus brasiliensis (Wille) (Hemiptera: Margarodidae), a soil scale that damages vine plants in southern Brazil. The daily foraging activity of L. micans and its seasonal preference for proteinand carbohydrate-based foods were evaluated. The study was carried out in a greenhouse usi...
We used an individual-based molecular multisource approach to assess the epidemiological importance of Triatoma brasiliensis collected in distinct sites and ecotopes in Rio Grande do Norte State, Brazil. In the semi-arid zones of Brazil, this blood sucking bug is the most important vector of Trypanosoma cruzi--the parasite that causes Chagas disease. First, cytochrome b (cytb) and microsatellit...
Rock bass (Ambloplites rupestris) are a widespread centrarchid species with both riverine and lacustrine populations. After precipitation events, rivers often carry elevated silt loads, where as lakes generally remain free from suspended silt and sediment. To examine the physiological effects of silt on rock bass, we conducted a series of experiments using fish from Lake Opinicon and the Grand ...
Pierce's disease is a major threat to the California grape industry. The disease-causing bacterium Xylella fastidiosa is vectored by a number of leafhoppers including Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae). Experiments were conducted to study H. vitripennis preference, feeding, and survivorship in response to four Vitis genotypes. Plants of V. vinifera ('Chardonnay'), V. gir...
