Objeto de conferencia II Congreso de la Sociedad Latinoamericana de Ecología de Vectores (LA SOVE) (La Plata, 29 de octubre al 3 de noviembre de 2022) Uruguay has monitored the presence of Aedes aegypti since 1997, when its reintroduction was reported. Since then, different methodologies have been used (larval surveys, control of strategic points, method of rapid survey of Aedes aegypti indices, traps). The LIRAa methodology is effective in detecting the main containers that are acting as breeding sites for Ae. aegypti in a certain area. However, the larval indices obtained are not sufficient to estimate the risk of arbovirus transmission because they do not provide a reliable estimate of the adult population, they do not take into account the distribution in transmission clusters and are heavily operator-dependant. The objective of this work was to improve the surveillance system in order to identify sites and periods with high Aedes density and help prevent future outbreaks of arbovirosis.

Objeto de conferencia II Congreso de la Sociedad Latinoamericana de Ecología de Vectores (LA SOVE) (La Plata, 29 de octubre al 3 de noviembre de 2022) Triatoma infestans is the main vector of Trypanosoma cruzi, the causative agent of Chagas disease in the southern cone. Resistance to pyrethroid insecticides reported in T. infestans populations could be one of the main causes of the persistence of vectorial transmission in the Argentinean Gran Chaco ecoregion. Chemosensory proteins (CSPs) are small soluble proteins from arthropods, with a studied role in olfaction. Recent evidence points to a role of these proteins in insecticide susceptibility and resistance. Accordingly, previous results from our group showed that some members of T. infestans CSP family are modulated four hours after an intoxication with deltamethrin.

Objeto de conferencia II Congreso de la Sociedad Latinoamericana de Ecología de Vectores (LA SOVE) (La Plata, 29 de octubre al 3 de noviembre de 2022) Is there just one science, the one we have, the given? Or on the contrary, are there several possible sciences? In the later case: which are their differences? Are they compatible? Complementary? Opposite? I will try to persuade the audience that at least three sciences can be distinguished: original blend, techno-science (normal science) and science of the postnormal age (call it transcendent science as it needs to go outside its field into the realm of decision making). I will distinguish the three at the epistemological level (arguably the deepest level) so that it may happen that what is scientific knowledge for one is not so for another.

Immature forms extract oxygen from aquatic macrophytes, common in lentic ecosystems such as dams and lakes. This biological characteristic makes its maintenance in the laboratory challenging. The present study aimed to evaluate the oviposition preference of Mansonia in different species of macrophytes, and in polystyrene sheets. Four species were studied; Mansonia humeralis, Ma. amazonensis, Ma. titillans and Ma. indubitans. The specimens were obtained in the community of São Domingo, located in Porto Velho, Rondônia.

Objeto de conferencia II Congreso de la Sociedad Latinoamericana de Ecología de Vectores (LA SOVE) (La Plata, 29 de octubre al 3 de noviembre de 2022) Chagas is a complex socio-environmental health problem characterised by the dynamic interrelation of different aspects with dimensions of diverse nature (biomedical, epidemiological, sociocultural, political-economic, and others). In other words, Chagas is much more than a disease and, in order to address it, it is essential to understand not only key aspects of the parasite, its routes of transmission, and medical aspects, but also the views of the different actors involved, public policies, the rights of the affected people... Admitting this helps us understand that any answer that seeks to generate contextualised and sustained solutions over time, must include and bring these different dimensions into play.

Objeto de conferencia II Congreso de la Sociedad Latinoamericana de Ecología de Vectores (LA SOVE) (La Plata, 29 de octubre al 3 de noviembre de 2022) We developed integrated vector surveillance (IVS) proposals, both for cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL) in the Americas, based on eco-epidemiological studies conducted by researchers of the Leishmaniasis Research Network of Argentina-REDILA. For CL, the transmission was explained in the framework of the edge effect, the increase of vectors and risk of exposure at ecotones and environmental interfaces, and typified as ephemeral, transient, or permanent edges. This approach supports a cost-effective IVS strategy for early warning of CL outbreaks, through an environmental modification alert network, which includes multiple sources of information and actors.

Objeto de conferencia II Congreso de la Sociedad Latinoamericana de Ecología de Vectores (LA SOVE) (La Plata, 29 de octubre al 3 de noviembre de 2022) Anaplasma marginale is a gram-negative obligate intracellular tick-borne bacterium that infects erythrocytes of ruminants and other mammalian host species from tropical and subtropical world regions. In Argentina, the transmission of A. marginale is mainly associated to the one-host tick, Rhipicephalus microplus. Although the presence of A. marginale DNA was previously confirmed in R. microplus larvae by PCR, the transovarial transmission of the bacterium in the tick remains neglected. The aim of the present study was to detect and molecularly characterize A. marginale in the bovine and in organs from R. microplus engorged female removed from the host, in order to determine the A. marginale genotypes involved in the transmission process. For this purpose, blood and tick samples were obtained from a bovine with acute Anaplasmosis at an endemic region in Corrientes province, Argentina.

Within the framework of this prioritization, in recent years diseases have not been incorporated because the absence of vectors limits their dispersion and development in the territory, as in the case of Grapevine flavescence dorée phytoplasma, the causal agent of one of the most important yellowing diseases of the vines in Europe, since its vector Scaphoideus titanus is absent in Argentina and South America.

In addition to its direct pathogenic effects, as anemia and low production, it´s also the vector of Babesia bigemina, B.bovis and Anaplasma marginale, agents that cause babesiosis and anaplasmosis, which often leads to the death of animals. Control with chemical products has been difficult in recent decades due to the development of resistance, residues in animal products and subproducts and environmental contamination.

Objeto de conferencia II Congreso de la Sociedad Latinoamericana de Ecología de Vectores (LA SOVE) (La Plata, 29 de octubre al 3 de noviembre de 2022) Yellow fever is currently increasing in importance in Argentina due to outbreaks in neighboring countries such as Brazil and Paraguay that cover a great part of the Misiones and Corrientes border. Due to several epizootic events in the south of Brazil between 2020 and 2021, in March and April 2021, we perform a mosquito survey to evaluate abundance and distributions of species vectors of Yellow fever virus (YFV) in several selvatic locations with presence of monkey Alouatta caraya in Northeast of Corrientes province: Las Marias, Tají Poty, Garabi, Garruchos, San Carlos, Colonia Liebig and near the Chimiray stream.

Objeto de conferencia II Congreso de la Sociedad Latinoamericana de Ecología de Vectores (LA SOVE) (La Plata, 29 de octubre al 3 de noviembre de 2022) Currently, Triatoma infestans is the main vector of Chagas disease in Argentina, Paraguay, and Bolivia. As many T. infestans populations present insecticide resistance, directly impacting control campaigns, alternative control methods, like those based on behavioral manipulation are needed. Bug nutritional and developmental status modulate bug responsiveness to host-related sensory cues. In order to understand the molecular bases of this modulation, we sequenced the antennal transcriptome of T. infestans and compared the gene expression profiles between unfed and fed insects.
