| ABSTRACT Chagas disease, caused by the Trypanosoma cruzi, has a wide distribution in South America, and its main method of control is the elimination of triatomines. It is presented here the geographic distribution and the rate of natural infection by T. cruzi of triatomines collected and evaluated from 2008 to 2013 in southwest of Bahia. Triatomines were captured in the intradomiciliary and peridomiciliary areas of five cities located in the southwest of Bahia state, identified, and analyzed for the presence of trypanosomatids in their feces. During the study period the number of patients suspected for acute Chagas disease was recovered from the Notifiable Diseases Information System (SINAN). 8966 triatomines were captured and identified as belonging to... |

| The effects of cyclic temperatures on Aedes albopictus Skuse development, longevity, gonotrophic cycle and the number of oviposited eggs were assessed by means of laboratory experiments. The experiments were carried out with mosquitoes from Registro, São Paulo, Brazil, kept in insectary for two years. The development of the insect was followed from egg to adult emergence under 25/18ºC and 27/20ºC and adult stage under 27/20ºC, both associated with LD 12:12h. The eggs received two treatments: (A) maintenance of water volume; (B) periodical and complete change of water. Blood meal was offered daily and it was interrupted after haematophagy and restarted after first oviposition. The immature development was significantly different under the temperature... |

| The present research aimed at evaluating the influence of the water quality in the life cycle and attraction of Aedes aegypti (L.) females to oviposit using different sources of water (raw sewage, effluent of UASB reactor, effluent of polishing lagoon, effluent of anaerobic filter, rain water and de-chlorinated water). The immature development time and survivorship were evaluated on a daily basis in two distinct feeding systems (with and without food). The quality of the water was shown to affect the egg and larval stages, but not the pupal or the adult. In the absence of food, no development was observed in rain water and de-chlorinated water. Immature development was faster in water sources from raw sewage, although with the lowest survivorship (37.3%).... |

| Sharpshooter leafhoppers (Hemiptera, Cicadellidae, Cicadellinae) in citrus groves of the area of Bebedouro, SP, with description of a new species of Acrogonia Stål. Sixteen species of Cicadellidae, subfamily Cicadellinae, were collected and identified: 11 of the tribe Cicadellini and five of the tribe Proconiini. The ten most common species, together with a new species, are characterized based on external morphology and male genitalia: Acrogonia citrina Marucci & Cavichioli sp. nov.; Bucephalogonia xanthophis (Berg, 1879); Dilobopterus costalimai Young, 1977; Ferrariana trivittata (Signoret, 1854); Hortensia similis (Walker, 1851); Macugonalia cavifrons (Stål, 1862); M. leucomelas (Walker, 1851); Oncometopia facialis (Signoret, 1854); Plesiommata... |

| Este estudio evaluó la respuesta fisiológica en plantas de jitomate (Solanum lycopersicum L.) y de tabaco (Nicotiana tabacum L.) inoculadas con un consorcio de hongos micorrízicos arbusculares (HMA) o con Rhizophagus intraradices, e infectadas con el Tobacco mosaic virus (TMV). Además, se analizó la posible transferencia de partículas virales a través de las hifas de los HMA de una planta enferma a una planta sana. Este trabajo se dividió en dos capítulos, el primer capítulo describe el crecimiento, el contenido de clorofila total, la determinación de la fosfatasa ácida de la raíz, el contenido total de compuestos fenólicos, la actividad antioxidante total, y la colonización micorrízica, en plantas de jitomate colonizada por R. intraradices e infectada por... |

| This is the first record of Culex (Culex) brethesi (Dyar) in Rio Grande do Sul state, Brazil. The species was identified from specimens collected in a sand bar vegetation with the aid of a Nasci's trap, during an expedition for surveillance of the West Nile Virus in July of 2006, in the city of Mostardas, Rio Grande do Sul, Brazil. |

| Abstract The housefly Musca domestica is a worldwide insect pest that acts as a vector for many pathogenic diseases in both people and animals. The present study was conducted to evaluate the virulence of different local isolates of Beauveria bassiana, Metarhizium anisopliae and Isaria fumosorosea on M. domestica using two bioassay techniques: (1) adult immersion and (2) a bait method applied to both larvae and adults. The results showed evidence of a broad range of responses by both stages (larvae and adults) to the tested isolates of B. bassiana, M. anisopliae and I. fumosorosea. These responses were concentration-dependent, with mortality percentages ranging from 53.00% to 96.00%. Because it resulted in lower LC50 values and a shorter lethal time, B.... |

| We investigated the use of Bacillus thuringiensis isolated in the state of Amazonas, in Brazil, for the biological control of the dengue vector Aedes aegypti. From 25 soil samples collected in nine municipalities, 484 bacterial colonies were obtained, 57 (11.78%) of which were identified as B. thuringiensis. Six isolates, IBt-03, IBt-06, IBt-07, IBt-28, IBt-30, and BtAM-27 showed insecticidal activity, and only BtAM-27 presents the five genes investigated cry4Aa, cry4Ba, cry10Aa, cry11Aa, and cry11Ba. The IBt-07 and IBt- 28, with lower LC50 values, showed equal toxicity compared to the standards. The isolates of B. thuringiensisfrom Amazonas constitute potential new means of biological control for A. aegypti, because of their larvicidal activity and the... |

| Potato yellow vein virus (PYVV) expresses yellowing symptoms on plants and it is transmitted by the whitefly vector Trialeurodes vaporariorum Westwood. No molecular viral detection from the vector extracts has been reported to date. The objectives of this study were I) amplification of the PYVV major coat protein (CP) gene from viruliferous vector extracts by RT-PCR using specific primers, II) cloning and III) sequencing and sequences analysis. Some Colombian Solanum phureja (Jus et Buk) field potato plants expressing yellowing symptoms and confirmed PYVV positive by RT-PCR were used as virus donor plants for feeding whiteflies. Viruliferous vectors were obtained by depositing aviruliferous whiteflies on symptomatic leaves and kept in a muslin... |

| Ips typographus (Coleoptera, Scolytinae) is a spruce-infesting bark beetle that occurs throughout Europe and Asia. The beetle can cause considerable damage, especially when colonized trees are stressed and beetle populations increase. Although some studies have shown that populations of I. typographus in Europe, China and Japan are genetically distinct, these populations are biologically similar, including a strong association with ophiostomatoid fungi. To date, only two Leptographium spp. have been reported from the beetle in China, while 40 species have been reported from Europe and 13 from Japan. The aims of this study were to identify the ophiostomatoid fungal associates of I. typographus in north-eastern China, and to determine whether the fungal... |

| The relationship of the citrus canker bacterium Xanthomonas axonopodis pv citri with the citrus leafminer (CLM), Phyllocnistis citrella Stainton was investigated. The experiment was conducted under laboratory conditions at 28±2ºC, 70±10% RH and 14h photophase and in a greenhouse. Sweet orange (Citrus sinensis L. Osbeck) "Caipira"cv was used to rear CLM. Plants inoculated with 2nd and 3rd instar larvae or pupae showed high percentages (94.3, 98.3 and 100%, respectively) of bacterium-infected leaves. The damage caused by this insect was responsible for the increase in citrus canker infestation. The leaf infection rate by X. axonopodis pv citri on pre-injured leaves was similar to that observed on mechanically damaged leaves inoculated with the bacterium,... |

| In order to determine the risk of transmission of Trypanosoma cruzi by triatomines in Metztitlan municipality, Hidalgo State, Mexico, entomological indexes were calculated and the characteristics of dwellings were described. A transversal, retrospective, descriptive, and observational study was performed by means of an intentional not probabilistic and expertise sampling from January to December of 2005 in 10 localities in which presence of triatomines were investigated either intra or peridomestic environmental in 699 houses. Building material and presence of infected triatomines with T. cruzi were registered to determine entomologic indexes. The triatomine species collected were: Triatoma barberi (Usinger) and T. mexicana (Herrich-Schaeffer) (Hemiptera:... |
