One of the Technical Note prepared by the Oswaldo Cruz Institute (IOC/Fiocruz) provides guidelines to improve the surveillance of Oropouche fever vectors in the state of Rio de Janeiro.
Produced in response to a demand from the State Department of Health (SES-RJ) to guide municipal surveillance services in Rio de Janeiro, the document presents information on collection methods, identification and control measures for the insect. Culicoides paraensis, primary vector of Oropouche fever, popularly called maruim or sandfly.
The publication was prepared by entomologists Maria Luiza Felippe Bauer, researcher at the Diptera Laboratory and curator of the Ceratopogonidae Collection at the IOC; Maria Clara Alves Santarém, deputy curator of the same Collection; and Nildimar Honório, researcher at the Laboratory of Host Virus Interactions of the IOC and coordinator of the Mosquito Vector Sentinel Operational Center (Nosmove/Fiocruz).
The Technical Note was published by the Undersecretariat of Surveillance and Primary Health Care in the section dedicated to Oropouche fever on the panel Arboviruses from SES-RJ.

Considering the current scenario of Oropouche fever, with a rise in cases in the country and confirmed transmission in the state of Rio de Janeiro, the researchers highlight the importance of correctly identifying the insect, which is very small in size, measuring around 1,5 mm, and belongs to a complex of species with very similar morphological characteristics.
The note addresses the taxonomy and biology of C. paraensis, detailing aspects relevant to the identification of the species, such as the pattern of spots on the wings and characteristics of the spermatheca, including photos.
The document guides procedures for collecting insects, indicating the type of trap and the most favorable time for capturing maruins. It also includes a form template for recording fieldwork information.
The main vector control measures are highlighted in the text. Considering that there are no insecticides, larvicides or repellents effective against the insect, it is recommended to avoid exposure during peak vector activity times and wear clothing that covers the body, such as long pants and a long-sleeved shirt, among other measures.
