This study deals with rearing methods, growth and mortality performances, and problems encountered by the oyster farmers from Quiberon Bay (2800 ha of leases) : it relies on a survey achieved in july 2001, about 18 oyster farmers, and 2 diving campaigns (july and october 2001) on 2 years old oyster batches from the same farmers. The analysed enterprises vary in particular by the location and depth of their concession inside the bay, but also by their rearing scheme : a majority favours seedings with 18 month old oysters or more, according to prices and availability of oysters supplies. The duration until marketable size and mean mortalities seem to have increased since a preceding inquiry in 1986. The main constraint, affecting priorly the south border...

Associações entre Cinara atlantica, seus inimigos naturais e formigas. Repositório Alice
PENTEADO, S. do R. C.; LAZZARI, S. M. N.; REIS FILHO, W.; NICKELE, M. A..
O estudo das relações existentes entre espécies ou populações é uma excelente ferramenta para se conhecer os fenômenos ecológicos. Dentre as interações possíveis entre duas espécies destaca-se o mutualismo entre formigas e insetos que produzem honeydew. Enquanto o honeydew é um "lixo" para os afídeos, pode ser fonte de alimento para as formigas. O tipo de interação existente entre afídeos e seus inimigos naturais, denominada "predação intraguildas" ou predação por inimigos naturais que dividem a mesma presa, é uma interação que ocorre nas comunidades de afídeos. A maioria dos inimigos naturais nesse sistema interage assimetricamente em função das diferenças no tamanho do corpo, estratégia de alimentação e prioridades de cada espécie. Em agroecossistemas, a...

Biological control of phytophagous arthropods in the physic nut tree Jatropha curcas L. in Brazil Agronomy
Fernandes, Flávio Lemes; Fernandes, Maria Elisa de Sena; Lopes, Elisângela Novais; Venzon, Madelaine; Diniz, Juno Ferreira da Silva; Dias, Luis Antônio dos Santos.
Jatropha curcas has a high biofuel oil content, which could replace polluting fuels, and has great potential for large scale monoculture cultivation in the conventional system. We explored the occurrence, spatial distribution and the functional response of the main phytophagous species of this plant and their natural enemies to explore the potential for conservative biological control. We began sampling phytophagous species and predators when J. curcas plants were six months old. The most common species of phytophagous insects were nymphs and adults of Empoasca kraemeri, followed by Frankliniella schultzei and Myzus persicae. Among the predators, Ricoseius loxocheles, Iphiseioides zuluagai, Araneidae, larvae and adults of Psyllobora vigintimaculata and...

Biology and olfactory response of Salpingogaster nigra Schiner (Diptera: Syrphidae). Repositório Alice
VERÍSSIMO, B. A.; AUAD, A. M.; SILVA, S. E. B.; SILVA, G. B. da.
Summary Salpingogaster nigra is a promising species for biological control of the spittlebug Mahanarva spectabilis Distant (Hemiptera: Cercopidae). This study determined the biology of the immature stage, as well as aspects of S. nigra adult behavior. Female fertility, egg viability, and the duration and viability of the larval and pupal stages were evaluated. Behavioral aspects were studied by the olfactory response of mated females, with a Y-type olfactometer. We assessed predator response to spittlebug nymphs vs. clean air; spittlebug nymphs vs. spittlebug foam, and spittlebug foam vs. clean air. Female fecundity reached 25.1 ± 6.1 (SE) eggs per female per d, and egg viability was 64.0% ± 4.5%. Duration and viability of the larval period were 10.5 ± 0.4...

Control of the pH for marine microalgae polycultures: A key point for CO2 fixation improvement in intensive cultures ArchiMer
Gales, Amandine; Triplet, Sebastien; Geoffroy, Thibault; Roques, Cécile; Carre, Claire; Le Floc'H, Emilie; Lanfranchi, Mélissa; Simier, Monique; Roque D'Orbcastel, Emmanuelle; Przybyla, Cyrille; Fouilland, Eric.
Recently, CO2 recycling for the production of valuable microalgae has acquired substantial interest. Most studies investigating CO2 conversion efficiency in algal cultures were based on single species, although a stabilising effect of algal diversity on biomass production was recently highlighted. However, addition of CO2 into polyalgal cultures requires a careful control of pH; performance of CO2 conversion, growth and carbon biomass production are affected by pH differently, depending on the species of microalgae. This study investigates the efficiency of CO2 conversion by natural marine algal assemblage cultivated in open, land-based raceways (4.5 m3, 10 m2), working as high rate algal ponds (HRAP). Ponds were enriched with nitrogen and phosphate, pure...

Dark clouds and their silver linings: exotic generalist predators in augmentative biological control Neotropical Entomology
CLERCQ,PATRICK DE.
Several polyphagous arthropod predators are commercially available for augmentative biological control targeting mite and insect pests in a variety of cropping systems. A number of these predators are not native to the area of release. The current paper discusses benefits and risks of using exotic generalist predators as biocontrol agents. The fact that polyphagous predators are easily reared on unnatural foods and can be used against different pest species makes them attractive for commercialization. Polyphagous or facultatively phytophagous predators have less difficulty in maintaining their populations at low prey densities and can sometimes be introduced in the crop before the target pest is present, thus preventing the buildup of pest populations...

Desenvolvimento e sobrevivência ninfal de Podisus nigrispinus (Dallas) e Supputius cincticeps (Stål) (Heteroptera, Pentatomidae) em diferentes temperaturas Zoologia
Didonet,Julcemar; Zanuncio,José Cola; Sediyama,Carlos S.; Picanço,Martelo C..
The effect of temperature on the development of Podisus nigrispinus (Dallas, 1851) and Supputius cinctceps (Stål, 1860) was studied in order to adjust equations to predict the development of these predators under 18, 20, 25, 30, 32 and 35º±0.2ºC, relative humidity of 65±10% and photophase of 12 hours. Incubation period of the eggs and duration and viability of nymphal stage were quadratically influenced by temperature while egg viability decreased linearly with increased temperature. The best temperature for egg development was 29ºC for both species and for nymphal development of P. nigrispinus and S. cincticeps they were 29º and 28ºC respectivelly. Nymphal viability was highly affected by extreme temperatures, with optima around 24ºC for S. cincticeps and...

Diet and potential feeding overlap between Trichiurus lepturus (Osteichthyes: Perciformes) and Pontoporia blainvillei (Mammalia: Cetacea) in Northern Rio de Janeiro, Brazil Rev. Bras. Zool.
Bittar,Vanessa T.; Di Beneditto,Ana Paula M..
This study describes the diet and assesses potential overlap in the feeding habits of Trichiurus lepturus Linnaeus, 1758 and Pontoporia blainvilleiGervais & D'Orbigny, 1844 in northern Rio de Janeiro, southeastern Brazil. Fishes were numerically dominant in both diets, followed by cephalopods for P. blainvillei and crustaceans for T. lepturus. Both predators move along similar coastal feeding areas in northern Rio de Janeiro, but our results indicate differences in their resource exploitation, what allows for their coexistence.

Diet of four annual killifishes: an intra and interspecific comparison Neotropical Ichthyology
Laufer,Gabriel; Arim,Matías; Loureiro,Marcelo; Piñeiro-Guerra,Juan Manuel; Clavijo-Baquet,Sabrina; Fagúndez,César.
We examined the diet of 4 annual fishes, Austrolebias viarius, Austrolebias cheradophilus, Austrolebias luteoflammulatus and Cynopoecilus melanotaenia inhabiting temporal ponds of southeastern Uruguay, by analysis of stomach contents. Fishes were captured from fifty ephemeral ponds of Castillos Lagoon basin, in the region of the Humedales del Este. We identified 13099 individual prey items extracted from 669 stomachs of the four captured species. In the studied system, annual killifishes represents the most abundant and conspicuous top predators. Killifishes are generalist key predators at the ephemeral ponds of the studied system, consuming mostly aquatic items. Zooplancton represented the bulk of the diet in the four analyzed species, followed by eggs,...

Distance from the edge of forest fragments influence the abundance of aphidophagous hoverflies (Diptera: Syrphidae) in wheat fields Agronomy
Bortolotto, Orcial Ceolin; Menezes Junior, Ayres de Oliveira; Hoshino, Adriano Thibes; Campos, Thiago Augusto.
This study aimed to evaluate the influence of the distance from the edge of native forests on the abundance of aphidophagous hoverflies in wheat fields. The study was conducted in four commercial fields in the North of Paraná State, Brazil, during the wheat crop season of 2009. Two transects were surveyed parallel to the edge of the forest at two distances: 25 (“near”) and 525 meters (“far”) from the edge. The abundance of hoverflies was compared using a χ2 test (p ≤ 0.05). In total, 1,845 hoverflies adults were collected, which represented 15 species and three genera. The most abundant species was Allograpta exotica (60.43%), followed by Toxomerus dispar (17.78%) and Toxomerus watsoni (7.26%) (Diptera: Syrphidae). An important inference was that all...
