| L’étude porte sur l’évolution du pH et de la température au cours de la transformation artisanale du Cymbium, ainsi que sur les perspectives de valorisation du produit transformé. Les expérimentations menées au site de transformation artisanale de Joal ont permis de constater que : Après 12 heures de séjour en bac (1ère nuit), le Cymbium est encore en phase de rigor mortis. Le pH moyen affiché à l’issue de cette première nuit est de 7,6 ; donc proche de celui du mollusque vivant ; Le pH moyen du produit fini est légèrement acide et se situe entre 6,3 et 6,4. Donc le yeet de Joal est très peu fermenté ; Les difficultés de séchage notées sont dues : soit au manque de maîtrise des paramètres tels que, la température, l’humidité relative et la vitesse de... |

| Observations on living estuarine nematodes show that previous feeding type classifications do not accurately represent the trophic structure of an intertidal mudflat in the Westerschelde Estuary (Netherlands). A new scheme with six major nematode feeding guilds is proposed: (1) microvores; (2) ciliate feeders; and (3) deposit feeders sensu stricto are all nematodes without a distinct buccal armature. In the first two groups bacteria and protozoa, respectively are the major particulate food sources, while other items are included in the diet of the third. The three other categories are recognized among the nematodes with a buccal armature: (4) epigrowth feeders; (5) facultative predators; and (6) predators. Diatoms and other microalgae are an important... |

| A busca por informações sobre as espécies de cerambicídeos associadas à Ocotea puberula (Rich.) Nees (Lauraceae) em galhos cortados por Oncideres cervina Thomson, 1868 (Cerambycidae: Coleoptera), motivou o presente estudo. De 49 galhos cortados do hospedeiro na região central do estado do Rio Grande do Sul, determinou-se a emergência de cerambicídeos com avaliações bissemanais. Além de O. cervina, o serrador dos galhos, foram observadas três espécies de cerambicídeos, Trestonia capreola (Germar, 1824), Dihammaphora signaticollis Chevrolat, 1859 e Tropidozineus rotundicollis (Bates, 1863) (Cerambycidae: Coleoptera), sendo para duas o primeiro registro de planta hospedeira desta família botânica. O período de emergência dos cerambicídeos de galhos de O.... |

| I hereby revise, for the second time, the primarily Neotropical solenopsidine ant genus Megalomyrmex, describing M. wettereri n. sp., of the Silvestrii group, based on workers and gynes. Megalomyrmex latreillei Forel is synonymyzed under M. foreli Emery. The gyne of M. poatan is described and that of M. wallacei redescribed; males of M. acauna, M. incisus and M. wallacei are described.

| The objective of this work was to develop suitable and economic diets for mass rearing Mediterranean fruit fly, Ceratitis capitata (Diptera: Tephritidae). Diets containing sugar beet bagase, wheat bran, brewer yeast, and others with wheat bran and palletized soybean protein from Brazil were tested. Diets based on soybean protein have shown promising results regarding pupal recovery, pupal weight and adult emergence. Soybean bagase in the form of pellets with 60% of protein can be a very important substitute for other expensive sources of protein. |

| This work was carried out with the objective of evaluating growth and development of sourgrass (Digitaris insularis) based on days or thermal units (growing degree days - GDD). Two independent trials were developed aiming to quantify the species' phenological development and total dry matter accumulation in increasing or decreasing photoperiod conditions. Plants were grown in 4 L plastic pots, filled with commercial substrate, adequately fertilized. In each trial, nine growth evaluations were carried out, with three replicates. Phenological development of sourgrass was correctly fit to time scale in days or GDD, through linear equation of first degree. Sourgrass has slow initial growth, followed by exponential dry matter accumulation, in increasing... |

| Availability of basic information on weed biology is an essential tool for designing integrated management programs for agricultural systems. Thus, this study was carried out in order to calculate the base temperature (Tb) of southern sandbur (Cenchrus echinatus), as well as fit the initial growth and development of the species to accumulated thermal units (growing degree days - GDD). For that purpose, experimental populations were sown six times in summer/autumn conditions (decreasing photoperiod) and six times in winter/spring condition (increasing photoperiod). Southern sandbur phenological evaluations were carried out, on alternate days, and total dry matter was measured when plants reached the flowering stage. All the growth and development fits were... |

| This work was carried out with the objective of evaluating the growth and development of honey weed (Leonurus sibiricus) based on days or thermal units (growing degree days). Thus, two independent trials were developed to quantify the phenological development and total dry mass accumulation in increasing or decreasing photoperiod conditions. Considering only one growing season, honey weed phenological development was perfectly fit to day scale or growing degree days, but with no equivalence between seasons, with the plants developing faster at increasing photoperiods, and flowering 100 days after seeding. Even day-time scale or thermal units were not able to estimate general honey weed phenology during the different seasons of the year. In any growing... |

| Discusses concepts of competition in economics and ecology and the relevance of evolution to both subjects. It is suggested that although speciation or increasing biodiversity tends to occur in undisturbed ecological systems, the opposite trend may occur in economic systems. Competition based on optimisation plays a significant role in theories of the evolution of species and some theories of the evolution of business or industrial structures. But evolution does not result in optimal selection of species or businesses for the future, and there is scope for doubt about what is being optimised by survivors in the evolutionary process. Ecological or biological theories of intra-specific competition involving scramble and contest competition are outlined and... |

| The biology of nymphs and adults of the neotropical pentatomid, Dichelops melacanthus (Dallas), feeding on the natural foods, soybean, Glycine max (L.) Merrill immature pods, and corn, Zea mays L. immature seeds, and on an artificial dry diet, was studied in the laboratory. Nymph developmental time was shorter on the natural foods (ca. 21-22 days) than on the artificial diet (28 days), and most nymphs reached adulthood on the food plants (55% on soybean and 73% on corn) than on the artificial diet (40%). Fresh body weight at adult emergence was similar and higher for females raised as nymphs on the natural foods, compared to females from nymphs raised on the artificial diet; for males, weights were similar on all foods. Mean (female and male) survivorship... |

| Biological aspects of Leucothyreus alvarengai Frey and Leucothyreus aff. semipruinosus Ohaus (Coleoptera, Melolonthidae, Rutelinae) in crop succession at central Brazil. Beetles of the family Melolonthidae make up a large group and some species are considered pests of planted crops. Little information is available on the basic biological aspects of the genus Leucothyreus, such as association with cultivated crops and their occurrence periods. Therefore studies were developed in soybean and corn crops in Tangará da Serra, Mato Grosso, Brazil, with the objective of studying the occurrence and biological aspects of Leucothyreus alvarengai Frey and Leucothyreus aff. semipruinosus Ohaus. For acquisition of immature specimens of both species, in April 2011... |
