| The french fishery of anchovy is divided in two groups defined by gears : purse seine and pelagic trawl. The average length of these vessels is about 20m. This fleet is very opportunistic : all trawlers are using several trawls during the year, to catch sometimes bass, tuna, hake, or scampi, and purse seine are mainly fishing sardine. Each year, the main anchovy catches are provided by pair trawlers. Purse seiners operate often in coastal areas (<10 nautical miles); trawlers may operate until 50 nautical miles offshore but are banned inside the three miles coastal zone. The pair trawlers may operate from Basque country to western Channel according to fish availability. Purse seiners usually stay around their home harbour. |

| The annual activity calendars of the 2,000 Breton fishing boats registered in the national POP file (with the exception of seafaring ships: 35 ocean-going tuna boats and 2 ships from Saint-Malo) were reconstituted for the year 1994 through surveys of the owners of these ships. Resorting to this method was necessary to overcome the weak statistical coverage of coastal fishing activity that is practiced within the 12 miles of territorial waters. This collection of information made it possible to build a database that contains, for each boat, the various trades practiced during the year 1994 and, if applicable, the periods of inactivity. By "trade", we mean the putting to use of a fishing vessel in order to catch one or several target species, in a given... |

| A beam trawl survey of the Bay of Vilaine was conducted from 1981 to 1997. Changes in the commercial fish community were analyzed by comparing the characteristics at the year and decadal scales. The community structure and nursery function of the Bay were steady during the period. However, specific richness, assiduity and distribution indices demonstrated a reduction in the second decade. The global abundance fell from 105.8 ind.ha-1 to 31.3 ind.ha-1. This trend was less marked for the external more marine stratum, which exhibited the lowest densities. The results are discussed in terms of ecological meaning of such a community, compared with the overall demersal fish community. The reasons of the decrease are questioned regarding nursery habitat, local... |

| Trophic level (TL)-based indicators have been widely used to examine fishing impacts in aquatic ecosystems and the induced biodiversity changes. However, much debate has ensued regarding discrepancies and challenges arising from the use of landings data from commercial fisheries to calculate TL indicators. Subsequent studies have started to examine survey-based and model-based indicators. In this paper, we undertake an extensive evaluation of a variety of TL indicators across 9 well-studied marine ecosystems by making use of model- as well as surveyand catch-based TL indicators. Using detailed regional information and data on fishing history, fishing intensity, and environmental conditions, we evaluate how well TL indicators are capturing fishing effects... |

| In this work, an alternative method for the capture of neotropical social wasps is described, which may supplement or replace the procedures commonly used in wasp surveys. The method was tested in a seasonal semideciduous forest in the northwest of São Paulo State, collecting a larger number of species and a greater abundance of social wasps and of other Hymenoptera than other methods also used in the same area, namely Malaise traps, bottle traps and meat baits. The proposed method was adapted from Wille (1962) who used an attractive solution based on water and honey for bee attraction. In here, the attractive solution was based on water, salt and crystal sugar, and was effective in attracting bees and solitary wasps, but mainly social wasps, which is the... |

| The diamondback moth Plutella xylostella (L.) has a great economic importance in Brassicaceae crops in many parts of the world. Recurrent infestations of this pest in growing areas of Pernambuco state, Brazil, have led farmers to frequently spray their crops with insecticides. However, control failures by several insecticides have been alleged by farmers. The objective of this study was to check whether resistance to insecticides could explain these control failures in P. xylostella. Populations of P. xylostella from Pernambuco were collected between January and April 2009. The resistance ratios of P. xylostella populations were compared among five different active ingredients: abamectin, methomyl, lufenuron, indoxacarb, and diafenthiuron by leaf dipping... |

| The coreoid fauna from Neotropics is poorly known, especially in terms of community studies. Aiming at contributing to this knowledge, a two-year study was carried out at Parque Estadual do Turvo, Municipality of Derrubadas, state of Rio Grande do Sul, Brazil, to evaluate the composition, abundance and species richness of Coreoidea. Samplings were conducted in the springs of 2003 and 2004 (October), and autumns of 2004 and 2005 (May), using beating tray method, along two trails of the park. Sampling effort (hours X collectors) totaled 153h. A total of 282 individuals of Coreoidea were collected, distributed in 28 species of Alydidae, Coreidae and Rhopalidae. The most abundant species was the coreid Cebrenis supina Brailovsky, representing 16% of the... |

| The occurrence of Cerambycidae (Lamiinae) was evaluated in trunk and branch samples of cardeiro (Scleronema micranthum), a forest species from the Central Amazon. Samples were exposed to biodegradation for 24 months on the forest soil, during which adults and larvae were collected and their attack was evaluated. From a total of 643 cerambycids collected, 606 were immatures and 37 were adults. Two species of Acanthoderini, Psapharochrus longispinis (Bates) (17 specimens) and Steirastoma melanogenys White (17 specimens) were collected, as well as one species of Onciderini, Jamesia globifera (Fabricius) (three specimens). Most larvae were found in the bark of trunks and branches, while pupae and adults were mainly found in the sapwood. |

| A survey of social wasps was made in the area of the "Ferreira Penna" Research Station (ECFPn) in Caxiuanã, PA, Brazil. Traditional collecting methods as the use of Malaise traps and the search for individuals and colonies of wasps along trails in the forest and by river margins, were applied in a more systematized fashion. Seventy-nine species belonging to 18 genera were discovered within a discontinuous period of 52 days of collecting. Angiopolybia pallens, Polybia liliacea, and several Agelaia species were the most frequently collected species. Active search for wasps in the forest and by river margins was far more efficient than Malaise traps regarding the discovery of polistine species. |

| Brassica oleracea var. acephala L. (kale) is widely grown in the Black Sea Region of Turkey. Kale growing has not been common in the other regions of Turkey. A number of diseases can seriously afect Brassica crop production. Field surveys were done to determine the occurrence of viruses in kale-growing areas in Ordu in 2013-2014. Leaf samples were collected from kale plants and tested for the presence of Turnip mosaic virus (TuMV), Cauliflower mosaic virus (CaMV), Turnip yellow mosaic virus (TYMV), and Cucumber mosaic virus (CMV) by DAS-ELISA and bioassays. Result of serological and biological tests showed that 7.7% of these samples were infected with TuMV. However, CaMV, CMV, and TYMV were not detected in any of the tested kale plants. The occurrence of... |
