This study aimed to determine the coexistence and food sources of adult mosquitoes (Diptera: Culicidae) in a rural health center in Piura, Peru by using a descriptive cross-sectional design. Entomological techniques were used to capture and identify mosquitoes, and molecular biotechnology techniques were used to identify food sources. A total of 793 specimens of the Culex and Aedes genera were found coexisting, 789 (99.5%) were Culex quinquefasciatus, 607 (76.9%) were males and 182 (23.1%) were females. Likewise, 4 (100%) corresponded to Aedes aegypti females. The food sources of Aedes aegypti were Homo sapiens sapiens, and Homo sapiens sapiens and Canis familiaris were the food sources of Culex quinquefasciatus. This study provides evidence that rural health centers could be acting as foci of arbovirosis, with the risk that people who come for different ailments could contract diseases transmitted by C. quinquefasciatus and A. aegypti.

Knowing the composition of mosquito community, their temporal dynamics and relationship with abiotic factors in urban areas is of interest in public health because many species are vectors of pathogens. This is the first survey of diurnal adult mosquitoes in an urban reserve in Buenos Aires City (Argentina). Fortnightly daytime samples were carried out during a year affected by a drought due to La Niña effect, to describe the adult mosquito community and analyze its association with environmental variables. Ten species belonging to the genera Culex L., Aedes Meigen, Psorophora Robineau-Desvoidy and Mansonia Blanchard were captured, some of which are vectors of pathogens (e.g. Aedes albifasciatus (Macquart) and the complex Culex pipiens L.). Diversity did not vary significantly among seasons, and the composition was moderately similar (ANOVA: p = 0.11; Dice-Sorensen: 0.50-0.77). However, classification of species as core, common or rare in the community varied. A canonical correspondence analysis allowed us to identify a group of five species associated with summer and high temperatures. The other species were not grouped, and were associated with rainfall, relative humidity or another season. These associations help to understand the presence and abundance of those species during a prolonged drought. [ABSTRACT FROM AUTHOR]

Introduction: Dengue is a viral, systemic disease, of endemic-epidemic character, caused by any of the 4 serotypes of the viral complex. It is transmitted to the man through the Aedes mosquito bite that causes the infection. Objective: To evaluate the level of knowledge about dengue in residents of a health area in Sancti Spíritus. Methods: A quantitative investigation, of preexperimental design, contextualized, was carried out in 174 people of 15 and more years, belonging to the Family Doctor Office No. 7 of Los Olivos Polyclinic in Sancti Spíritus province, from February to July, 2022, for which the structured interview was used. The analyzed variables were level of knowledge about dengue, age, sex and school level. After the intervention the populational proportions were compared. Results: There was a prevalence of the 45-55 years patients (53.1 %), female sex (66.7 %) and the secondary school level finished (55.1 %). After concluding the educational activities, the individuals reached appropriate results and their level of knowledge on the disease had an increase. Conclusions: The intervention was effective in the studied population, because the knowledge about dengue had increased. [ABSTRACT FROM AUTHOR]

Since the beginning of the 21st century, a bibliography on the printed image in 19th century Buenos Aires has been consolidated. However, Correo del Domingo (1864-1868) has not yet been the object of a longterm research, even though the publication founded by José María Cantilo, along with El Mosquito (1863-1893), made the 1860s a turning point in the history of the local illustrated press. In this article we will concentrate on the analysis of the editorial configuration of the weekly publication. We identify as its greatest formal innovation the fact that it brought together different resources, which could be found years before in the newspaper's feuilleton or in literary publications, converging in a periodical that made a qualitative leap in the experience of reading the press and opened a path that would culminate in the turn-of-the-century magazine. Specifically, we will analyze how discursive genres associated until then to the newspaper's rezde-chausée (in particular, the serialized novel) were incorporated into the weekly format, as well as an unprecedented display of lithographic images, throughout a generous publication that multiplied the usual four pages of the contemporary press to attract an expanded and diversified readership.

Malaria is a serious public health problem in Colombia, with Plasmodium falciparum and P. vivax as the parasites responsible for 97% of malaria cases. The municipality of Turbo is one of the most affected departments in Antioquia, recording 7076 malaria cases in 2019. The objective was to identify the Anopheles spp. present in endemic areas of malaria transmission in Turbo and to evaluate their natural infection with Plasmodium spp. A total of four samplings were carried out between 2015 and 2016 in both wet and dry seasons each year. The mosquitoes were collected in the intra-domicile and peri-domicile, and on corral animals. In addition, active searches were carried out for immature stages in natural breed sites of water pools. A total of 121 adult mosquitoes were collected, belonging to four species: An. albimanus (n = 117), An. triannulatus s.l. (n = 1), An. apicimacula s.l. (n = 1) and An. pseudopunctipennis s.l. (n = 2). Sixty-five larvae belonging to three species were collected by active searches: An. albimanus (n = 58), An. triannulatus (n = 1) and An. apicimacula (n = 6). None of the specimens collected was found infected naturally with Plasmodium. Anopheles albimanus could be the main malaria vector in the localities studied, due to the high densities found and its vector capacity recorded in Colombia. Possibly, An. pseudopunctipennis s.l. may play a role in malaria transmission if infected people were present and in areas with high mosquito densities found in this study showed that vector control strategies implemented in 2014-2015 by local health institutions with Bacillus sphaericus and insecticides are proving to be effective.

Advanced oxidation processes have been useful in the degradation of organic molecules that contaminate drinking water or wastewater. However, little is known about the toxic effects on living organisms present in such environments. Our objective was to quantify the functional and morphological response of Aedes aegypti aquatic larvae treated with different oxidant molecules used in advanced oxidation conditions. Stage IV Aedes aegypti mosquito larvae were distributed into four groups: a control group, one treated with 3% H2O2, one treated with O3, and one treated with the combination H2O2 + O3. After 1 hour of treatment, locomotor behavior and anatomical changes were obtained based on the response of the larvae to the stimulus of UV light, recorded through videos and images processed in the Video Trcker program and the ImageJ program. Fiji, respectively. The data were analyzed with the GraphPad Prims program. At a functional level, the larval population treated H2O2 presented a decrease in the displacement speed, with asymmetric and inconstant movements and with loss of periodicity, contrary to the response emitted by the controls that were expressed with an increase in the displacement speed. Group O3 presented a response similar to the controls; however, the travel speed presented greater amplitude. The H2O2 + O3 group showed the greatest transformations, with a greater decrease in the displacement speed, accompanied, at the anatomical level, by signs of air embolism characterized by the presence of intracorporeal air bubbles, as well as by a reduction in morphometric parameters such as body size, cephalic and thoracic. It is clear that advanced oxidation processes could generate toxic effects that limit the functionality of living organisms that are part of the global ecology of aquatic bodies.

Introduction: Many mosquitoes are of great medical and veterinary importance because they transmit numerous pathogens which cause diseases in animals and humans; thus, knowing their taxonomy and distribution is pivotal for implementing the correct control strategies. The aim of this study was to determine the occurrence of mosquito species and their distribution in La Comarca Lagunera in the state of Durango, Mexico. Method: Adult mosquitoes were collected at different resting sites in four municipalities between August and November 2018 using Insectzookas. Aquatic habitats were also sampled for immature stages. Adult specimens were killed using lethal chambers with triethylamine vapors; while larvae and pupae were stored in individual tubes to obtain the adult stages and associated exuviae. All material was transported to the Molecular Biology Laboratory of the Parasitology Department of the Universidad Autónoma Agraria Antonio Narro, Unidad Laguna (UAAAN-UL) for mounting and taxonomical identification. Species were identified using taxonomic keys for the region. Results: In total, 689 mosquito specimens (286 males and 403 females) were collected belonging to 15 species, among them Anopheles franciscanus McCracken, Culex erythrothorax Dyar, and Toxorhynchites moctezuma (Dyar and Knab) are new records for Durango State. The most abundant species was Cx. quinquefasciatus Say with 364 (56.2%) specimens, followed by Aedes aegypti (Linnaeus) (21.3%) and Ae. vexans (Meigen) (7.7%). Conclusion: 13 out of 15 species collected are associated with the transmission of an arbovirus of relevant medical or veterinary importance in Mexico. There are now 38 species recorded for Durango. The information in this study is directly relevant for the Health Ministry in Durango State for the control of vector borne diseases in the region. [ABSTRACT FROM AUTHOR]

Dengue is a recurrent public health problem that affects the American continent. Recent records indicate a historical raise in number of cases in South America, particularly, in Brazil, Paraguay and Bolivia. Correspondingly, in Argentina, outbreaks have occurred almost all years except 2001 and 2005 since 1998. Furthermore, in 2009, 2016 and 2020 the epidemics reached almost half of the country. Therefore, dengue appears to be configured as a disease that cannot be prevented or controlled. As a consequence, our initial aim is to find and examine the meanings about the dengue problem that circulate among health agents and neighbors in a locality in the province of Buenos Aires. We conducted in-depth interviews to health local agents of different status in two health centers and participant observations in local trainings to agents between December and February 2019. According to our findings dengue does not seem to be a problem for the neighbors nor for some of the interviewed health agents. Mosquito bitings and some health problems are the subjects of concern. The preventive measures associated with container treatment are limitted by the multiple meanings and uses that people give to containers. Furthermore, we find that fumigations have many meanings. They appear as the only possible solution and, on the contrary, as a tool of political legitimacy. Similarly, the liability problem is discussed in the interviews with the health workers. In general, we can say that this study supports what is stated in other researches regarding the presence of fractures between the ideals of locality programs and the people's daily life.

Malaria is a potentially fatal disease which is caused for parasites transmitted to humans by the bite of female infected mosquitoes of the anopheles gender. Analyzing the effect of mobility and the fact that there are individuals who respond differently to the disease can contribute to the planning of strategies to prevent the spread. In view of the above, it is proposed to study the dynamics of malaria considering that individuals belong to a specific group and are distributed in disjoint plots that are connected in some way. For this, a multipatch and multigroup model is proposed using the Ross-Macdonald model as a basis, in which mobility is incorporated from the Lagrangian approach where all individuals belong to a specific group but spend part of their time in an arbitrary number of patches. The qualitative analysis is performed based on the basic reproductive number and the results showe that the mobility and dividing the population of humans and mosquitoes into groups changing the dynamics of the disease.

We present a preliminary report on the richness and distribution of aquatic Diptera in the department of Chocó, from 490 specimens (larvae and pupae) kept in the Chocó Limnological Collection (CLCH-Insec), corresponding to 18 municipalities (between 5 and 3202 m a.s.l.), 46 water streams of different order and 14 lentic ecosystems of the Atrato, San Juan and Baudó Rivers basins. There are 12 families and 30 genera, of which 4 families and 16 genera are recorded for the first time for Chocó. Chironomidae is the most abundant and most widely distributed family, while Dixidae and Sciomyzidae are the families with lowest abundance and distribution. The highest taxonomic richness is recorded for the families Culicidae and Ceratopogonidae, with five genera each. Macrophytes are the substrate with the greatest specific richness. The largest taxonomic record is found in the Atrato River basin, with 11 families and 24 genera. These results show the enormous diversity of aquatic Diptera in the department of Chocó and the need to develop new research that will broaden their taxonomic and ecological knowledge in the region.

The active dispersion in mosquitoes consists of the movement of an individual beyond the limits of its population from origin, influenced by searching for various resources. It is an important population component that should be included in the design of programs for management and control of mosquito-vector-mediated infections. Its estimating is based on Marking, Releasing and Recapture (MLR) methods. Although in Venezuela, there are not currently works based on this and other techniques, there are a variety of studies that contribute to elucidate the main tools for the marking and recapture of mosquitoes, necessary to estimate their flight ranges. Based on these studies, we present a review of the most important aspects of MLR techniques applied to the study of active dispersal in mosquitoes of vector importance, addressing the concepts associated with dispersal in mosquitoes, the main types of marking and traps for recaptures, As well as the application of dispersion values in spatial risk models. This has allowed clarifying the suitability of each technique according to the requirements of each study and the selection of those that allow minimizing the possible biases or errors in the experiment.

Culex (Culex) garciai was first described by González Broche (2000) from specimens collected in the eastern Cuban provinces of Granma and Santiago de Cuba, between 120 and 620 MASL, respectively. Later, the species was also found in the province of Havana above 65 MASL. In this study, the first records of this species from Hispaniola are given. Cx. garciai has been located in a mountainous rural area in the municipality of Jarabacoa, Province of La Vega, Dominican Republic, between 528 and 657 MASL. Immature stages have been found in natural and artificial habitats, such as rocks pools, bamboo trunks, temporary rainwater puddles and artificial containers. [ABSTRACT FROM AUTHOR]

Mosquitoes are responsible for the transmission of various diseases that affect the health of the Venezuelan population. The increase in the incidence of malaria and the emergence of diseases such as chikungunya and Zika make it necessary to implement control measures to reduce the impact of these diseases in Venezuela. To do this, it is essential to know the aspects related to their morphology, bioecology and the characteristics that make possible the participation of mosquitoes in the transmission of these diseases. The purpose of this review is to describe these aspects. [ABSTRACT FROM AUTHOR]

Two species of uncommon mosquitoes (Diptera, Culicidae) were collected during late April and early May 2017, in a mountainous rural area located above 1,500 MASL: Aedes (Rusticoidus) refiki Medschid, 1928 and Aedes (Ochlerotatus) pullatus (Coquillett, 1904). A total of 626 specimens were collected, with larval densities in favor of Ae. refiki (87%). A new larval association between both species, to date unknown, was described. The culicids were located in a normally snowy environment during the winters, in the Alto Tajo Natural Park (Guadalajara, Community of Castilla-La Mancha) and in the Montes Universales (Teruel, Autonomous Community of Aragon). Thus, in this contribution two new provincial records for Guadalajara and Teruel. [ABSTRACT FROM AUTHOR]

A compilation of the results obtained in several projects developed between the years 2004 and 2015 on the presence of the mosquitoes of the family Culicidae in the surroundings of the Devesa and Racó de l'Olla of the Albufera Natural Park of Valencia (Spain). A total of 10 species belonging to five genera (Aedes, Coquillettidia, Culex, Culiseta and Ochlerotatus) were recorded, some of them very characteristic of the environments where they were collected. Different aspects are discussed on the culicid diversity, as well as on the ecological and health interest of the presence of these species. We highlight the presence of the species Aedes albopictus (Skuse, 1894) in a space limited by housing, built in the 1970s, and not collected in the malladas. [ABSTRACT FROM AUTHOR]

The research of alternative food for aquatic species with high economic potential is one of the main topics of study in aquaculture. The present study evaluated the consumption of pre-adult mosquitoes by four ornamental fish species Carassius auratus, Pterophyllum scalare, Danio rerio and Xiphophorus helleri. The experimental design consisted of four treatments with three replicates. Each assay was performed independently between species. In each aquarium (1 l) two juvenile fish were placed, the wet weight and total length (mean ± standard deviation) were known. 100 larvae were supplied in one of the treatments, and 100 pupae in the other one. The daily rate of larvae and pupae consumption was recorded at an interval of three hours during a 24-hour time period per each species. Pre-adult mosquitoes wet weight differed 5.20% and dry weight 37.69%, both were higher in mosquito's pupae (p < 0.001). The fish were more active during the light phase, 09:00-1 8:00 h, as evidenced by a higher consumption rate of mosquito's larvae and pupae. Carassius auratus had the highest consumption 131.33 ± 4.16 larvae/fish/24 hour and 86.16 ± 3.20 pupae/fish/24 hour, which significantly different compared to P. scalare, D. rerio and X. helleri (p < 0.001). Finally Carassius auratus showed an excellent ability to ingest pre-adult mosquitoes. [ABSTRACT FROM AUTHOR]

After the recent detection of Aedes albopictus (Skuse, 1894) in Southwestern France, the entomological surveillance in the Basque Country, since 2013, has found two positive traps in Irun (Guipuzkoa). The differences in environmental conditions, which could influence its establishment, between this area and the Spanish Levante populations are discussed. Also, this is the first record of Culex hortensis Ficalbi, 1889 and Culiseta longiareolata (Macquart, 1838) for the Basque Country and the Guipuzkoa province. Also it is the first record of Cx. pipiens Linnaeus, 1758 for the Guipuzkoa province. [ABSTRACT FROM AUTHOR]

Introduction. The spread of dengue is attributed to the expanding geographic distribution of the four serotypes of dengue and the spread of its mosquito vectors, Aedes aegypti and Aedes albopictus. Ae. aegypti reinfestations began in the 90s in several provinces of Cuba along with the introduction of Ae. albopictus in 1995. Objective. Determine the spatial and temporal distribution of Ae. aegypti and Ae. albopictus breeding sites in Pinar del Río province, Cuba from 2003-2010. Materials and Methods. Larval collections were made throughout the province, following the methodology of the Ae. aegypti control program. Results. Ae. aegypti presence increased in 13 (92.8%) of all municipalities in the province in 2010, while Ae. albopictus was found in 100% of the municipalities in the province in 2008. Both species were distributed in significant quantities across municipalities located in the south-central part of the province, in areas with: grassy plains, major urbanization, and areas with main transport routes. Increased mosquito presences were found from July to October, coinciding with higher positive values in standing water in ground level tanks and in small artificial containers, although at different rates. Ae. albopictus showed a preference for breeding in larvae traps. Ae. aegypti and Ae. albopictus showed both low association between them and with other species of mosquitoes. Conclusion. Ae. albopictus populations are expected to become endemic in the province, replacing Ae. Aegypti, in a large part of the province, requiring continuing studies by the researchers.

Malaria is a protozoan infectious disease caused by parasites of Plasmodium genus. Most cases are caused by Plasmodium vivax, although the more severe clinical features are observed by Plasmodium falciparum and Plasmodium knowlesi infection. Worldwide estimation of malaria cases during 2010 was of 216 million persons infected, approximately 81% of them (174 million cases) were recorded in Africa. In Venezuela, there were 45,743 malaria cases in 2011. Pathogenesis of the disease is based on the cyclic invasion and rupture of erythrocytes, which leads to the generation of malarial paroxysms, comprising chills, fever, sweating and hemodynamic changes that could evolve in worst cases to splenic rupture in Plasmodium vivax infection, or during severe malaria due to Plasmodium falciparum infection. The gold standard diagnostic procedure remains the thick and thin stained blood smears. The major preventive measure is to avoid mosquito bites, the vector, through the use of repellents, mosquito nets, and other measures. The disease is presenting a resurgence in Venezuela and the commemoration of the centenary of Professor Félix Pifano, MD, a pioneer of Tropical Medicine studies, we considered important to update this endemic disease that was assessed and studied with great dedication by Professor Pifano. Nowdays, as happen in past years, when malaria decimated patriot and royalist armies, during Bolivar independence war, malaria continue presents a resurgence, affecting the Venezuelan population.

The oviposition period of Aedes aegypti L. was studied for Santa Rosa, La Pampa, Argentina. Ovitraps were placed during the year 2011 in five different locations of this city and weekly samplings were carried out during that year. The relationship between temperature and weekly oviposition activity was also studied and a stop in the oviposition activity was observed when the temperature dropped below 16°C. These data allow us to extend the knowledge of this vector in the provincial capital, providing as well the necessary information to implement control measures in this city. [ABSTRACT FROM AUTHOR]
