SILVA, Fábio Daniel Florêncio da; OKADA, Yukari  and  FELIPPE-BAUER, Maria Luiza. Culicoides Latreille (Diptera: Ceratopogonidae) from Alter do Chão village, Santarém, Pará State, Brazil. Rev Pan-Amaz Saude [online]. 2010, vol.1, n.3, pp.69-74. ISSN 2176-6215.  http://dx.doi.org/10.5123/S2176-62232010000300010.

The aim of this work was to survey Culicoides Latreille fauna and to record their seasonal abundance in a beach area from the village of Alter do Chão (Municipality of Santarém, Pará State, Brazil). Collections were made monthly between May 2006 and April 2007 using CDC light trap and human attraction. A total of 58 specimens were collected belonging to five species: C. crucifer Clastrier, C. insinuatus Ortiz & Leon, and C. fusipalpis Wirth & Blanton species were collected while biting humans; C. insignis Lutz was collected by CDC light trap. C. ruizi Forattini midges were collected utilizing both methods. The most abundant human-biting species collected was C. crucifer, while C. insignis was the predominant species collected using CDC light traps. The greatest incidence of Culicoides occurred in October 2006. During the survey, no correlation between climatic factors and the number of Culicoides collected each month was observed using the Spearman coefficient.
