The Aedes aegypti species, originating from the African continent, has been dispersed worldwide due to the transportation of slaves, becoming a significant vector for viruses causing diseases such as Zika, Chikungunya, and Dengue. Climate change and tourism have increased the spread of these diseases, and efforts to prevent and control mosquito-borne diseases, including Ae. aegypti, involve the use of insecticides, although this practice has not been highly successful in recent decades. Heat, light, and noise pollution are common in urban environments; therefore, this study aimed to analyze the exposure of larvae to LED light of white, green, and blue colors and their interactions with sound vibration waves at 14, 20, and 40 kHz, respectively. Each experimental unit resulted in a different dynamic in the decrease of the number of live larvae over time, with variations in the rate and magnitude of reduction. Blue light + 40 kHz showed a faster and more pronounced decrease in the number of larvae compared to other treatments and the control treatment, followed by Green light + 20 kHz. White light + 14 kHz showed no difference from the control treatment, being the least efficient. Based on these results, this study introduces a new method of controlling Ae. aegypti using natural resources such as light and sound.

The Aedes aegypti mosquito has become one of the main problems in urban centers, where it transmits various diseases to humans. In this way, it is fundamental to carry out an investigation before the control measures of this vector. Synthesize the actions developed to face Aedes aegypti in the Brazilian context. This is a bibliographic, descriptive study, type of integrative review. The search was performed LILACS (Latin American and Caribbean Health Science Literature), Scielo (Online Science Electronic Library), PubMed (United States) Academics of the National Library of Medicine of the National Institutes of Health (Academic Google) with full text available in the language (Portuguese, English and Spanish). The selection of studies was organized through the prism flowchart. IRAMUTEC software was used for data processing and analysis. Data were analyzed through descending hierarchical classification and words from the cloud. The results found: 31 studies were selected from 120 found. with the representation of six classes with strategies: entomopathogenic fungi; Larvivor fish; Wolbachia Pipientis; RILD and techniques; Botanical insecticides; larvicides; Pyriproxyfen; technological monitoring; Regular visits by ACS; EcoShoth Approach; MIV and campaigns. It is concluded that there are several strategies to face and develop new control techniques.
Perfil epidemiológico e atualidades no tratamento e prevenção contra DENV2 no Brasil

Dengue, a systemic infection caused by a virus transmitted by the Aedes aegypti mosquito is widely described in the literature as a major worldwide public health problem. Over the years, given the worldwide distribution and consequent occurrence of worldwide epidemics, dengue has become the target of relevant studies. Currently, it is known that dengue virus comprises five different serotypes, named: DENV-1, DENV2, DENV-3, DENV-4 and DENV-5. Among these, DENV-2 has been reported in many countries, including Brazil, as the serotype responsible for the highest severity of dengue. Here, the objective was to produce a bibliographic survey about the epidemiological aspects and etiological agents associated with DEN2, highlighting the current pharmacotherapy and the perceptive treatment and prevention. Thus, since the first records of DENV-2 infection in Brazil, this serotype has a wide national distribution, although the number of studies that characterize the epidemiological profile of dengue by serotypes is limited. As far as treatment is concerned, there is currently no pharmacotherapeutic scheme that can combat all dengue serotypes and this has serious socioeconomic implications as it results in high medical costs. Finally, although there are different studies focusing on the development of vaccine strategies, including virus-like particle approaches (VLPs), there is also a need to explore these approaches given the occurrence of adverse events and reduced efficacy.
