Analysis of pollen load based on color, physicochemical composition and botanical source Anais da ABC (AABC)
Modro,Anna F.H.; Silva,Izabel C.; Luz,Cynthia F.P.; Message,Dejair.
Pollen load samples from 10 hives of Apis mellifera (L.) were analyzed based on their physicochemical composition and botanical source, considering color as a parameter for quality control. In seven samples it was possible to establish the occurrence of more than 80% of a single pollen type, characterizing them as unifloral but with protein content variation. One of the samples was exclusively composed of saprophytic fungi (Cladosporium sp.). Comparing the mean results of the fungi loads with those of the nutritional components of pollen load, the former presented higher protein, mineral matter and dry matter and lower organic matter, ethereal extract and total carbohydrate values. The monochromatic samples met the physicochemical specifications regulating...

Cultural aspects of meliponiculture. Repositório Alice
SOUZA, B. A.; LOPES, M. T. R.; PEREIRA, F. M..
Some ancient cultures from Central and South American had close contact with stingless bees. Their representation in decorations, drawings and sculptures is common in various indigenous groups, as part of its cosmology and relationship to the world. This group of social insects also represents an important source of food resources and income (honey, wax, resin, larvae and pollen). The use of these bees and their products as sources of food and income and in the cultural and religious expression are reviewed in this chapter, mainly regarding the Brazilian culture.

Determination of the chemical composition and functional properties of shrimp waste protein concentrate and lyophilized flour Ciência e Agrotecnologia
Brasileiro,Olivaldo Lacerda; Cavalheiro,José Marcelino Oliveira; Prado,João Paulo de Sousa; Anjos,Alinne Gouveia dos; Cavalheiri,Thais Tereza Brandão.
Wastes from the seafood industry can be easily processed into products with new forms of use. The present study was aimed at determining the chemical composition and functional properties of shrimp waste protein concentrate and lyophilized flour. The raw material used in this study consisted of waste (head) of Litopenaeus vannamei. The protein concentrate was obtained by ethanolic extraction, being subsequently submitted to drying in oven at 70° C, while the flour was obtained by lyophilization of shrimp wastes. Moisture, ash, protein and calcium contents showed significant difference between fresh shrimp head waste samples (IN) and protein concentrate and lyophilized flour samples. The protein content for protein concentrate (PC) and lyophilized flour...

Diversidade de Coccinellidae (Coleoptera) em plantas aromáticas (Apiaceae) como sítios de sobrevivência e reprodução em sistema agroecológico Neotropical Entomology
Lixa,Alice T; Campos,Juliana M; Resende,André L S; Silva,Joice C; Almeida,Maxwell M T B; Aguiar-Menezes,Elen L.
Studies show that Apiaceae may provide concentrated vital resources for predator insects, stimulating their abundance, diversity and persistence in agricultural systems, thereby increasing their efficiency as biological control agents. Among the predatory insects, Coccinellidae (Coleoptera) on many different species both as larvae and adults, complementing their diet with pollen and/or nectar. This study aimed to determine the diversity and relative abundance of Coccinellidae species visiting plants of Anethum graveolens (dill), Coriandrum sativum (coriander) and Foeniculum vulgare (sweet fennel) (all Apiaceae), particularly in their blooming seasons, and to evaluate the potential of these aromatic species for providing the resources for survivorship and...

Feeding rate of the oyster Crassostrea gigas in a natural planktonic community of the Mediterranean Thau Lagoon ArchiMer
Dupuy, Christine; Vaquer, André; Lam Hoai, Thong; Rougier, Claude; Mazouni, Nabila; Lautier, Jacques; Collos, Yves; Le Gall, Solange.
The Mediterranean Thau Lagoon is an important oyster farming area in Europe. Oyster growth rates are among the highest in France, although chlorophyll a concentration is low. Previous studies have demonstrated that picophytoplankton, nano-microphytoplankton, dinoflagellates and loricate ciliates such as tintinnids are abundant. However, heterotrophic flagellates and aloricate ciliates have not been investigated. The aim of this study was to assess picophytoplankton, protist and zooplankton abundances in the Lagoon and to investigate the particular structure of the microbial food web, which may explain such paradoxical oyster growth. In oligotrophic waters in the Thau Lagoon, the picoeukaryote Ostreococcus tauri is the dominant autotrophic picoplankter,...

Forrageamento de Melissoptila thoracica Smith (Hymenoptera, Eucerini, Apoidea) em flores de Sida (Malvaceae) Zoologia
Silva-Pereira,Viviane da; Alves-dos-Santos,Isabel; Malagodi-Braga,Kátia Sampaio; Leon Contrera,Felipe Andrés.
Foraging activity of a solitary bee species - Melissoptila thoracica Smith, 1854 (Eucerini) - was studied considering its phenology, floral preferences, foraging patterns and pollen's transportation structures. M. thoracica females present a clear preference for flowers of Sida Linnaeus (Malvaceae) in relation to pollen collection. The fidelity for the plant was observed considering foraging flights and analyzing the pollen carried in the females' scopes. The collection of pollen by bees was estimated throughout the counting of remaining grains in the anthers, over one and three visits. Females were examined in scanning electronic microscopy for the analysis of pollen grains in the ventral pilosity and in the scopes. M. thoracica was considered an...

Impact of the oyster Crassostrea gigas on a microbial community in Atlantic coastal ponds near La Rochelle ArchiMer
Dupuy, Christine; Pastoureaud, Annie; Ryckaert, Mireille; Sauriau, Pierre-guy; Montanie, Hélène.
To assess the in situ impact of oysters Crassostrea gigas on planktonic protist and bacteria communities and the potential contribution of protozoa to their food resource intake, the abundance and the diversity of protists and bacteria were followed in 2 Atlantic coastal ponds, with and without oysters. The protist biomass in such ponds was high, with a maximum in spring of 982 mug C l(-1) and a minimum in winter of 179 pg C l(-1). Whatever the season, the presence of oysters (20 m(-2) corresponding to an average of 23 mg dry weight m(-2)) induced a significant decrease in >5 pm protist abundance. On the contrary, planktonic organisms <5 pm, such as Chlorophyta flagellates and bacteria, developed similarly in both ponds. It can be assumed that such...

Relating diet, demographics and lifestyle to increasing US obesity rates AgEcon
Schroeter, Christiane.
Changes in the American lifestyle are putting more individuals at risk due to the declining quality of their diets. In the last 20 years, the readily available high-fat foods (e.g., "fast foods") combined with the decreased caloric requirements due to lower physical activity levels is assumed to be the major factor in the sharp rise in the prevalence of obesity. The typical away-from-home meal is less healthy than food at home, since it tends to contain more total fat and saturated fat, less calcium, fiber, and iron, and fewer servings of fruits and vegetables. Furthermore, due to the super-sizing trend that is sweeping the market, when Americans eat out, they eat more. Thus, a rising away-from-home consumption appears to establish a significant barrier to...

The corn pollen as a food source for honeybees - doi: 10.4025/actasciagron.v33i4.10553 Agronomy
Malerbo-Souza, Darclet Terezinha; Centro Universitário Moura Lacerda.
This experiment was conducted on the campus of the University Center Moura Lacerda, Ribeirão Preto, in 2009 and 2010 with the objective of verifying the attractiveness of corn pollen for the Africanized honeybees Apis mellifera. The frequency of these bees, and the foraging behavior and stability were obtained by counting the first 10 min. of each hour, from 7.00 to 18.00, on three different days. Africanized honey bees collected only pollen in male flowers of maize, with a peak frequency of 9.00 in 2009 and between 16.00 and 17.00 in 2010. The corn pollen was very collected by Africanized honey bees, an important food source for these bees.
