Comparative wood anatomy of the blueberry tribe (Vaccinieae, Ericaceae s.l.) Naturalis
Lens, F.; Kron, K.A.; Luteyn, J.L.; Smets, E.; Jansen, S..
Wood samples of 111 Vaccinieae specimens (Vaccinioideae, Ericaceae s.l.) representing 98 species and 26 genera are investigated with light microscopy and scanning electron microscopy. The wood structure of Vaccinieae delivers taxonomically important characters that can be used to define some subclades within the tribe. The wood of the large polyphyletic genus Vaccinium strongly resembles non-vaccinioid members of the family, which are characterized by bordered vessel-ray pits and relatively narrow (2- to 4-seriate) and low multiseriate rays (often less than 1000 mm) with exclusively or mainly procumbent body ray cells. The East Malesian clade, Meso-American/Caribbean clade, and the Andean clade show a combination of wood anatomical features that is lacking...

Consumer Acceptance and Willingness to Pay for Blueberry Products with Nonconventional Attributes AgEcon
Hu, Wuyang; Woods, Timothy A.; Bastin, Sandra.
Consumer acceptance and willingness to pay for three nonconventional attributes associated with six processed blueberry products was examined through an in-store conjoint experiment survey. Both credence and experience attributes were considered, including whether the products were produced locally, and whether they were organic or sugar-free. The results indicate heterogeneity in consumer preference and willingness to pay for different attributes across product categories. Local products and organic formulations generally received positive willingness to pay across all products. This information has implications for blueberry growers and retailers who are trying to create and position value-added products for maximum revenue.

The invasive spotted-wing Drosophila (Diptera, Drosophilidae) has been found in the city of São Paulo (Brazil) Rev. Bras. entomol.
Vilela,Carlos Ribeiro; Mori,Lyria.
The invasive spotted-wing Drosophila (Diptera, Drosophilidae) has been found in the city of São Paulo (Brazil). Drosophila suzukii (Matsumura, 1931), the cherry fly or spotted-wing Drosophila, a pest species from the Oriental and southeastern Palaearctic regions belonging to the melanogaster group, invaded the Nearctic and western countries of the Palaearctic regions late last decade (2008) and, more recently (2013), the southern Brazilian states of Rio Grande do Sul and Santa Catarina. Early in 2014 it was reared from blueberries produced in São Joaquim, state of Santa Catarina, that were bought at a São Paulo city grocery store. Despite being a cold-adapted species, after having arrived to the southeastern state of São Paulo, this invasive fly will...

Comparison of relative abundance and diversity of coccinellids (Coleoptera: Coccinellidae) in blueberries (Vaccinium corymbosum L.), under two production systems in the La Araucanía Region, Chile Ciencia e Investigación Agraria
Vera,Marcela; Aguilera,Alfonso; Rebolledo,Ramón.
Coccinellids have been used, throughout the world, in biological control programs of agriculture pests. In Chile this family has been studied by various authors, which addresses issues such as biology, predatory activity and distribution in herbaceous species, shrubs and trees, but their situation in blueberries, where there is an abundance of species, is unknown Coccinellid beetles were counted visually on two blueberry orchards, under organic and conventional management. This study was conducted at the Maquehue Experiment Station, in the central valley of "La Araucanía Región" in southern Chile, from September 2007 through May 2008 and was divided into two periods: from September 2007 through February 2008 with visual counts only on the foliage of the...
