| El gusano rojo de maguey es un recurso atractivo para los colectores y acopiadores que lo comercian en mercados y restaurantes a precios elevados, explotando las poblaciones silvestres sin un programa de manejo, esto ha causado reducción tanto de la planta de maguey como del insecto, por lo que es indispensable generar conocimientos que permitan realizar un mejor aprovechamiento de este recurso. En este trabajo se obtuvieron larvas de primer instar al incubar huevos en condiciones de laboratorio y se definieron aspectos básicos de biología y comportamiento de Comadia redtenbacheri, para lograr el establecimiento y desarrollo de su fase larvaria en plantas de maguey mantenidas en condiciones de invernadero. Los mejores niveles de infestación se... |

| Con la finalidad de identificar las especies de gallina ciega asociadas a las raíces del Agave tequilana Weber var. Azul, así como su fluctuación poblacional, se realizaron recolectas de larvas mediante muestras de suelo (30x30x30 cm) obtenidas mensualmente de septiembre de 2006 a agosto de 2007 y de adultos de mayo a agosto de 2007 utilizando una trampa de luz fluorescente negra. Las especies de gallina ciega asociadas al cultivo de agave tequilero fueron Cyclocephala comata (Bates), Phyllophaga ravida (Blanchard), Phyllophaga misteca (Bates), Phyllophaga polyphylla (Bates), Strategus aloeus (Linné) y Anomala hoepfneri (Bates). Las especies P. ravida y A. hoepfneri se reportan por primera vez asociadas al agave tequilero y esta última junto con... |

| Aedes (Stegomyia) albopictus (Skuse, 1894) larvae were recorded for the first time in the internodes of bamboo cuts found in the Atlantic Forest in the State of Paraná, Brazil. The bamboo, Bambusa sp., was introduced in the area of Imbucuí-Mirim town, across the municipal district of Paranaguá and towards the interior of the Atlantic Forest. A total of 251 larvae of Aedes albopictus (37.9%), Culex (Microculex) spp. (13.9%), Limatus durhami Theobald, 1901 (39.8%), Toxorhynchites sp. (0.4%) and Wyeomyia spp. (8.0%) were collected from bamboo internodes filled with rain and from the terrestrial Bromeliaceae and epiphytas found near the bamboo bushes. Aedes albopictus was found in bamboo internodes containing 30 to 254 ml of rain, sometimes coexisting with Li.... |

| Larva of Hemirhipus Latreille, 1825 is herein described for the first time. Larvae of Chalcolepidius porcatus (Linnaeus, 1767), from Peru, and Hemirhipus apicalis Candèze, 1857, from Argentina, are described and of Alaus myops (Fabricius, 1801), from USA (Illinois and Maryland), and A. oculatus (Linnaeus, 1758), from USA (Illinois and Florida), are redescribed and illustrated. A comparison among the known larvae in each genus is presented. An historical review and the larval characterization of five genera and fourteen species of Hemirhipini genera are also included. |

| The results of larval collections of mosquitoes from artificial containers and natural breeding at urban and rural areas carried out at Sertaneja, northern State Paraná, Brazil, from February to April, 1995, are presented. Among the 4534 immature forms collected, belonging to 21 species or species-groups, the species with higher density were Aedes aegypti (Linnaeus, 1762), Aedes albopictus (Skuse, 1894), Culex quinquefasciatus Say, 1823 and Limatus durhami Theobald, 1901. |

| The schooling behavior of Hyla semilineata Spix, 1824 tadpoles is described. Experiments were carried out both in the natural environment and under controlled conditions to quantify the constant movement of these tadpoles. Bullfrog tadpoles (Rana catesbeiana Shaw, 1802), similar in size to the H. semilineata larvae, were used as controls in the experiments. Hyla semilineata tadpoles remained stationary for one sixth of the time that the bullfrog tadpoles did and the number of individuals of H. semilineata moving at any given moment was about seven times greater. The schooling behavior and constant swimming behavior of these tadpoles may enhance the effect of their warning coloration. |

| In this study, we have evaluated the incorporation of two types of protein hydrolysates at 9 and 12% levels of inclusion, one from yeast (Saccharomyces cerevisiae, YPH) and another one from pig blood (PBPH), in microdiets for gilthead sea bream (Sparus aurora) larvae, and compared these results to a microdiet containing fish protein hydrolysate and another group only fed with enriched live prey (rotifers and Artemia). The trial consisted in substituting up to 75% (wt/wt) the enriched Artemia with the experimental microdiets from 15 to 40 days post-hatch, whereas larvae were exclusively fed on microdiets from 40 to 55 dph. Protein hydrolysates used in the present study were obtained from different raw materials (yeast, pig blood and fish protein... |

| In France, spatfall of Pacific Oysters occurs traditionally in two shellfish area of the south west of France: the Marennes-Oléron bay and the Arcachon basin. The spat collected in both sites ensures approx. 70 % of the need of the French oysters production (the other part is produced in hatcheries). But, since ten years, recruitment have become highly variable especially in Arcachon basin. For instance, in this site, spatfall (assessed at the end of the reproductive season) can vary between 50 oysters per collector to more than 20 000 oysters per collector (Figure 1). This huge variation arise questions from oysters producers and the French National Committee for Shellfish Culture want to get some explanations of the phenomenon. It is well known that... |

| Previous studies have shown heritable variation in larval developmental traits in the Pacific oyster Crassostrea gigas. In order to study the genetic consequences of production of oyster larvae in hatcheries, two factors, specific to hatcheries, were examined: the effect of discarding the smallest larvae (i.e. culling) and the effect of temperature (20°C versus 26°C). A mixed-family approach was used in order to infer the genetic composition of larval populations and family assignment, limiting possible environmental bias and allowing the study of a relatively large number of families using a limited number of larval tanks. Our results show that three multiplexed highly polymorphic microsatellite markers are a powerful tool for family assignment and,... |
