“…This phenomenon is known as metaxenia, where the pollen donor genotype may influence the physical and biochemical quality of the guava fruits (Usman et al, 2013). It has also been reported in apple (Bodor et al, 2008), blueberry (Silveira et al, 2011) and loquat crops (Xu et al, 2007). This observation suggests that it is possible to select pollinating genotypes in order to constitute a commercial orchard with the aim of increasing productivity and fruit quality.…”

Pollen viability is essential for the sexual reproduction in plants. Genetic and environmental factors as well as plant age can influence this characteristic. In this work, pollen viability was studied in guava (Psidium guajava L.), a cross-pollination species. The genetic parameters for this characteristic were estimated considering 22 genotypes, two environments and different plant ages. For that, the pollen viability of the genotypes was evaluated for three years (2013, 2014 and 2015) in two experimental orchards (installed in randomized block design, with three blocks and two plants per plot) and at two different regions of the state of Espírito Santo, Brazil. The plants were analyzed at 19, 24 and 38 months of age in the years 2013 and 2014 in Mimoso do Sul (ES) and 2015 in Linhares (ES), respectively. The flower buds, at pre-anthesis stage, were collected, fixed in ethanol:acetic acid (3:1) and stored at -20°C. Pollen viability was obtained by colorimetric methods (Alexander's, Acetic Orcein and Lugol dyes) and the genetic parameters estimated by means of mixed models. The pollen viability of the genotypes was high, with an overall mean of 93.46% in the thr ee harvests. Mean heritability was lower in the harvests of 2013 (0.479) and 2014 (0.126) in relation to 2015 (0.583), indicating a slighter possibility of predicting genetic gains based on this characteristic. Altogether, these results provide information about pollen viability in commercial and superior genotypes of the guava crop used in this study, given that pollen-donor genotypes are reported to influence characteristics related to weight and fruit quality in this species. In addition, these genotypes showed good potential for cross-pollination, and can therefore be used as pollinators in orchards and crosses within breeding programs.

“…Parasitoids of families Ichneumonidae and Braconidae were also collected, however, their hosts were not identified. According to Silveira et al (2011), bumblebees of the genus Bombus are the most efficient pollinators of blueberry under southern Brazil conditions while bees play a complementary role.…”

“…(RECALDE, 2008), while in the region on the west bank of the Uruguay River, the fruit flies Anastrepha fraterculus (Wiedemann) and Ceratitis capitata (Wiedemann) were recorded (GORDÓ, 2008). In Brazil, the existing information on insect pests associated with blueberry is scarce with studies on Naupactus tremolesari L., Tolype innocens (Burmeister), Trigona spinnipes (Fabricius) and Eurhizococcus brasiliensis (Wille) (GONÇALVES et al, 2009;LOUZADA et al, 2011;SILVEIRA et al, 2011;EFROM et al, 2012). Thus, the objective of this study was to know the insect fauna associated with the different phenological stages of the blueberry crop in Pelotas area, Rio Grande do Sul State, in order to obtain support for implementing integrated pest management to this culture.…”

-The blueberry (Vaccinium ashei Reade, Ericaceae) is a small fruit with great growth potential in Brazil. This research was developed in order to identify the insects found on associated to the different phenological stages of blueberry in order to implement the integrated pest management for this crop. Insect samples were collected from three orchards, in the region of Pelotas, RS, from January 2010 to June 2012. The data were analyzed based on the composition and abundance of the collected insects. In all three sites, 2,354 insects were studied and the majority belonged to Hymenoptera (72%), Coleoptera (16%), Hemiptera (6%) and Diptera (4%). Forty-one families were identified with 59% of the listed insects belonging to the Apidae family, followed by 11% for Chrysomelidae and Formicidae. Overall, 50 species of insects were identified and Trigona spinipes (Fabr.) and Apis mellifera L. were the most abundant. Of the species found, 78% were herbivores, while 22% was beneficial insects (pollinators, predators and parasitoids) belonging to the orders Hymenoptera, Coleoptera and Dermaptera. The analysis of variance with the randomization test showed that the insect fauna does not differ between locations and phenological stages. The interaction of site with phenological stages was not significant for the three grade levels (order, family and species). The knowledge of the entomofauna associated with blueberry, along with the similarity in composition with the phenological stages and evaluated sites, contributes to the development of integrated pest management and establishment of production system for this new culture in southern Rio Grande do Sul, Brazil.

ENTOMOFAUNA ASSOCIADA A DIFERENTES ESTÁDIOSFENOLÓGICOS DA CULTURA DO MIRTILEIRO RESUMO -O mirtilo (Vaccinium ashei Reade, Ericaceae) é uma das pequenas frutas com grande potencial de crescimento no Brasil. Este trabalho foi desenvolvido com o objetivo de conhecer a entomofauna associada aos diferentes estádios fenológicos do mirtileiro, com vistas à implementação do manejo integrado de pragas nesta cultura. Foram realizadas coletas de insetos em três pomares da região de Pelotas-RS, de janeiro de 2010 a junho de 2012. Os dados foram analisados com base na composição e abundância dos insetos coletados. Nos três locais, foram observados 2.354 insetos, sendo a maioria pertencente às ordens Hymenóptera (72%), Coleoptera (16%), Hemíptera (6%) e Díptera (4%). Foram identificadas 41 famílias, sendo 59% do total de insetos coletados pertencentes à família Apidae, seguida por 11% das famílias Chrysomelidae e Formicidae. Ao todo, 50 espécies de insetos foram identificadas, sendo Trigona spinipes (Fabr.) e Apis mellifera L. as mais abundantes. Do total de espécies encontradas, 78% foram consideradas herbívoras, enquanto o restante 2% esteve representado por insetos benéficos (polinizadores, predadores e parasitoides) pertencentes às ordens Hymenóptera, Coleóptera e Dermáptera.

“…They are able to grow and flourish with only 360 hours of chilling, while those in the group "highbush" need between 650 and 800 hours of chilling [10]. Silveira et al [19] found that even the source of pollen is important for the quality of fruits of the variety "rabbiteye" produced in the Southern region of Brazil. In addition, Rocha [11] remarks that the variety Bluegem, from the group "rabbiteye", is one of the most widely grown in the Southeastern region of Brazil due to its wide adaptation and lower cold requirement.…”

There is pressure from consumers about exchanging synthetic for natural dyes in foods. This review aimed to expose the potential of blueberry (Vaccinium myrtillus) as a source of natural dye, associated with its properties of functional food. Blueberry is a fruit plant natural from temperate climate, rich in phenolic compounds. The properties of phenolic compounds can be attributed to its ability to capture free radicals, deactivating or eliminating them from the body. Anthocyanins are flavonoid phenolic compounds responsible for color of fruits, flowers and vegetables. Blueberry is rich in anthocyanins, being its content more affected by genotype than by climatic or environmental factors. Brazil has the potential to assume an important position in the worldwide market of this fruit, both in natura and as byproducts, whose main destinations are populations from regions with higher income and educational level, as the North America and Europe. Due to the importance of blueberry as a source of natural pigments, as well as its high value while associated with functional food, it is important to improve extraction and stabilization processes of anthocyanins from blueberry fruits. Researches should focus on the technical viability and cost reduction in the extraction of this pigment. Pioneer studies with blueberry have been conducted in Brazil, but the intensification of researches will allow yield maximization, increased levels of anthocyanins in fruits, and compound stability after extraction. Another focus should be the use of these natural pigments in order to replace those currently used.
