| Abstract During the samplings described here, Aphidius avenae (=picipes) (Haliday, 1834) was collected. This species has been reported in Chile but has never been studied in terms of its relative abundance and prevalence in central and southern Chile by using classical or molecular methods. The composition of the parasitoid assemblages on several cereal aphid hosts was examined for three seasons in agricultural landscapes. In this note, we describe the prevalence of this parasitoid species in cereal aphids and other aphid hosts and discuss the abundance of this parasitoid compared to other aphid parasitoids and the probable origins of this important aphid parasitoid species in Chile. The results indicate that A. avenae has a low prevalence compared to... |

| The tick collection of the Museu de Historia Natural Capão da Imbuia was first sorted in the end of the 80's, and a list of specimens was published in 1992. During the last ten years, the collection has grown substantially and became the depository collection for type-specimens. The collection is the most regional representative depository of ticks from the State of Paraná, and it is one of the four largest Brazilian collections in number of specimens. All material was revised, and the data were computerized and catalogued in cards. To date, the collection includes 504 vials, with 2,073 specimens, belonging to 25 species and six genera of the families Argasidae and Ixodidae. The ticks were collected in regional and state parks and in green areas from 60... |

| Se estudió la diversidad y abundancia de escolítidos asociados al agroecosistema cacao en cuatro localidades del estado de Tabasco, México durante el año 2007. La recolecta de los insectos se llevó a cabo mediante trampas cebadas con alcohol etílico, captura con trampa de luz fluorescente y captura directa sobre sus plantas hospederas. Se recolectaron 19,263 especímenes pertenecientes a 51 especies y 26 géneros; Araptus hymenaeae y Cnesinus squamosus son nuevos registros para México. 40 especies son nuevos registros para el estado de Tabasco. Los géneros con mayor riqueza de especies fueron Hypothenemus (8) y Xyleborus (7). Las especies Xyleborus volvulus, X. affinis, Hypothenemus eruditus, H. birmanus y Premnobius cavipennis fueron las que en... |

| The Araucanía region is a berry producing area where important behavioral aspects of species in the genus Aegorhinus, a pest that affects crops, are still unknown. The objectives of this study were to determine the distribution, abundance and richness of these species in agroecological zones of La Araucanía Region and to determine the hosts in which they were found. The sites where these species were found were represented on a map divided into grids of 25 x 25 km. Eight species of Aegorhinus were found in the area, and Aegorhinus nodipennis and Aegorhinus superciliosus were the most abundant. The diversity was analyzed using the Shannon-Wiener index, and the equitability was determined using the Pielou index. The agroecological zone with the greatest... |

| There exists no biochemical test allowing to define the pathogenicity of a bacterium, still less for a Vibrionaceae. Two essential characters are to be retained to hold responsible an isolated germ, for an illness: 1) the binding factor, the identification is difficult but a double diffusion of agar should simplify the method; 2) the search for the choleric toxin or a common part of the choleric toxin (toxin LT or ST of E. coli ). Here again, simplified techniques may be used. The acquirement of a plasmid responsible for the binding factor or for the toxin production of the non-pathogenic Vibrionaceae in the origin of certain epidemic diseases in France and in the world. Frequently, epidemics due to common germs (Aeromonas hydrophila of Africa) lead to... |

| The irrigated rice production can be limited by various phytopathogenic agents, including root-knot nematodes (Meloidogyne spp.). Thus, the aim of this research was to check the host suitability of plant species most often found off-season and during rice cultivation, to root-knot nematode Meloidogyne graminicola, under two irrigation managements. Two experiments were conducted in a completely randomized design. In the first experiment seven plant species that occur in an area of rice cultivation, in fallow, off-season were evaluated. For the second experiment nine weed species infesting the irrigated rice culture were tested in rainfed and flooding conditions. The sixteen species, kept individually in pots with sterilized substrate, were inoculated with... |

| Un échantillonnage de poissons parasités (Diplodus puntazzo) en provenance d’une firme aquacole située au Sud-est de la Corse (Ouest méditerranéen) montre une infestation due à un Myxidium leei. Le parasite envahit l’épithélium intestinal causant amaigrissement du poisson et une forte mortalité. Les spécimens de plus de 16 cm de longueur totale étaient significativement moins infestés. Toutefois, l’infestation ne montre pas de différence significative entre mâles et femelles quelle que soit la taille des spécimens. Quelques paramètres hématologiques ont été utilisés pour montrer le rôle du parasite dans cette maladie de poissons et statuer sur l’interaction hôte-parasite. |

| Se evaluó el efecto de dos variedades de jitomate (“Charanda F1” y “Rafaello”) en la morfometría de B. cockerelli (Sulc). Se colectaron huevos, ninfas y adultos criados en dos variedades de jitomate “Charanda F1” y “Rafaello”, en condiciones de invernadero en el Colegio de Postgraduados, Campus Montecillo, Texcoco, México, en el periodo Octubre-Diciembre 2009 – Enero-Marzo 2010. Las condiciones generales de la cría fueron: sin aplicación de agroquímicos; los adultos fueron mantenidos en jaulas individuales de marco de madera cubiertos con tela de organza, bajo un periodo de 14 h de luz, con un rango de temperatura de 10 a 25° C. En el análisis de morfometría de huevos se consideraron las variables: Longitud de Huevo (LH), Ancho de Huevo (AH) y Longitud de... |

| Abstract Fruits of thirty-five cultivated native plant species (19 orders and 12 families) were sampled in farms of fruit production from two municipalities of São Paulo state, Brazil (January 2010 to March 2012) to evaluate species diversity of Neosilba flies. Thirty-one species of plants were the host for Neosilba species while four were not infested. Some aspects of the biology and patterns of species diversity, abundance, infestation rates, puparias viability and the interactions among species of frugivorous flies and their host plants were quantified. Seven species of Neosilba were reared: Neosilba bella Strikis & Prado (4 hosts), Neosilba certa (Walker) (4 hosts), Neosilba glaberrima (Wiedemann) (5 hosts), Neosilba inesperata Strikis & Prado... |

| The Neotropical genus of lance flies Neosilba McAlpine could be found associated with fruits, flowers or buds of plants. There are few basic or applied studies of these insects, including data on taxonomy and/or economic importance. We described ten new species from Colombia: N. plana sp. nov., N. tolimensis sp. nov., N. amphora sp. nov., N. convexa sp. nov., N. concava sp. nov., N. orbata sp. nov., N. spiculata sp. nov., N. angusta sp. nov., N. distospinosa sp. nov. and N. piracea sp. nov. We presented a key for the all 40 valid species of the genus, included in five groups and two subgroups: major, parva, peltae, pendula and glaberrima groups. Glaberrima includes the two subgroups glaberrima and certa, and pendula includes the pendula and nigrocaerulea... |

| The influence of two factors, age and previous experience, on the oviposition hierarchy preference of Ceratitis capitata (Wiedemann, 1824) females was studied. Two populations were analyzed: one reared in laboratory during 17 years and the other captured in nature. In the first experiment the oviposition preference for four fruits, papaya, orange, banana and apple was tested at the beginning of oviposition period and 20 days past. The results showed that the wild females as much the laboratory ones had an oviposition preference hierarchy at the beginning of peak period of oviposition. However this hierarchic preference disappeared in a later phase of life. In the second experiment the females were previously exposed to fruits of different hierarchic... |
