ABSTRACT
Se realizó una investigación en la localidad de Sevilla, ubicada en el municipio costero de Guamá, en Santiago de Cuba, para identificar las especies de insectos causantes de molestias en esta población, así como sus principales fuentes de cría y los horarios de mayor actividad hematófaga de los adultos, con vistas a dirigir eficientemente las estrategias de control de vectores. A tales efectos, se llevaron a cabo encuestas entomológicas larvarias y capturas de insectos adultos sobre cebo humano. Fue identificado el Leptoconops bequaerti (Kieffer) como la especie de mayor actividad hematófaga en el horario diurno, con mayor incidencia entre las 09.30 y 11.30 horas. Este trabajo constituye un nuevo informe para esta provincia, particularmente la mencionada localidad, y un elemento muy útil desde el punto de vista entomológico e higiénico-epidemiológico, pues estos jejenes son importantes transmisores de encefalitis virales y de otros agentes infecciosos, como las filarias y diversos protozoos.
An investigation was carried out in Sevilla town, located in the coastal municipality of Guamá, Santiago de Cuba, to identify the species of insects affecting this population, as well as their main breeding sources and the periods of the adults' greater hematophagus activity, for directing efficiently the strategies to control vectors. To achieve this, larvae entomological interviews and captures of mature insects on human bait were carried out. Leptoconops becquaerti (Kieffer) was identified as the species of greater hematophagus activity during daily hours, with more incidence between 09.30 and 11.30 hours. It was concluded that this new report of the province, and particularly of the mentioned site, constitutes a very useful element from the entomological, hygienic-epidemiological points of view, because gnats are important viral encephalitis and other infectious agents transmitters, as phylarias and diverse protozoos.

No trabalho, relatam-se os primeiros registros de Bradysia sp. (Insecta: Diptera: Sciaridae) em morangueiro (Fragaria x ananassa Duch.), cultivado no Município de Eldorado do Sul, RS. O cultivo foi realizado em sacolas com três metros de comprimento, preenchidas com substrato composto de casca de arroz e turfa, dispostas horizontalmente sobre bancadas de madeira, em ambiente protegido. A presença de Bradysia sp. foi observada na segunda quinzena de agosto de 2005. Neste trabalho, estão descritos os sintomas apresentados no morangueiro pela praga, prováveis conseqüências sobre o aparecimento de doenças e uma breve descrição morfológica da Bradysia sp., adulto e fase larval.
This paper describes the first record of Bradysia sp. (Insecta; Diptera; Sciaridae) in strawberry (Fragaria x ananassa), cultivated in the city of Eldorado do Sul, RS, Brazil. Strawberry was planted in plastic bags filled with a mixture of burnt rice hulls and peat and cultivated in a greenhouse. The presence of Bradysia sp was noticed in the second fortnight of August, 2005. The symptoms in strawberry and the probable consequences in terms of disease arising were described in the present study, as well as the morphological characterization of Bradysia sp. and its illustrations.
