Since its introduction in Spain in 2004, Aedes albopictus has rapidly spread across the country. Its aggressive biting behaviour causes nuisance, limiting outdoor activities. Also, its role as a vector of several arboviruses implies a major public health risk, with several cases of autochthonous dengue having been reported nationwide over the past few years. Control strategies usually focus on interventions in breeding sites. As such, accurate knowledge of the main larval habitats becomes a major priority in infested areas. A detailed identification of breeding sites of Ae. albopictus was carried out in the outdoors of 60 residential properties during July–August 2022 in El Vedat de Torrent (Valencia, Eastern Spain), an area recently colonised by this species. A total of 1444 real and potential breeding sites were examined. The most abundant potential larval habitat were plant pot plates (6.48 units/house), although a low infestation level was found, both for larvae (2.06% positivity, x̄ = 30.5 larvae/container), and pupae (0.51%, x̄ = 2.5 pupae/container). A total of 7715 larvae and 205 pupae were found in a disused flooded water pool depuration system. Animal drinkers, buckets and irrigation water containers were found to be the most common positive containers. No statistical difference was observed among the different container materials. A general statistical increase of 1 larva per 11.7 ml of water in breeding sites was detected. Breeding sites of other species such as Culex pipiens (n = 2) and Culex modestus (n = 1) were also rarely found in this residential area. To our knowledge, this is the first aedic index study carried out in Europe, and it provides valuable information about the main domestic breeding habitats of Ae. albopictus, which can greatly improve control programmes.

Aedes albopictus was first detected in the province of Valencia, Eastern Spain, in 2013. Since then, this invasive mosquito species has become a major pest in many municipalities due to its annoyance, but also to its importance as a public health concern as a potential vector of several arboviruses. Within the framework of the NESCOTIGER research project, several prevention and control activities were carried out during spring 2022 in the residential area of Torrent, a municipality recently invaded by the Asian tiger mosquito. An awareness campaign was conducted in the study area focused to both primary school students and residents. For children, talks in primary schools focusing on the basic aspects of the biology, prevention, control, and disease transmission of Ae. albopictus were conducted. For adults, a multi-pronged education campaign to mobilize the community in response to this mosquito species was devised, involving a series of workshops and local gatherings to raise awareness about Ae. albopictus. Additionally, a knowledge, attitude and practices (KAP) study was conducted on both children (n = 544; 75.7%) and adults (n = 175; 24.3%). Both adults and children showed low levels of knowledge concerning Ae. albopictus biology, control strategies, and breeding sites identification. Nevertheless, there was great interest in learning and participating in novel strategies against this Aedes invasive mosquito. Future awareness campaigns in the area should consider the information gathered here for the development of community-based strategies. This study is the first to collect information on the KAP of local community members since the detection of Ae. albopictus in Spain, and it is the first to compare KAP surveys between adults and children concerning this invasive mosquito.

Research on medical and veterinary entomology (MVE) is especially needed in the Caribbean islands, which are threatened by the burden of several arthropod species due to their tropical climate and environment. Identifying relevant MVE-related scientific activity in these countries and examining the characteristics of its outputs can aid in the analysis of trends, knowledge gaps and decision-making in vector-borne disease research management. This study used bibliometric methods to understand how research in this discipline developed in the insular Caribbean countries during the first two decades of this century. Data were extracted from the Web of Science Core Collection™ and SciELO Citation Index™. During the study period, the region’s scientific MVE production grew at a steady rate. Most studies focused on the order Diptera and the family Culicidae. Cuba is the largest regional producer. The predominance and growing trend of international scientific collaboration were observed. These scientific results are scattered and mainly published in journals in the United States and European countries. Recent MVE studies in the insular Caribbean have been promising; it is crucial to ensure knowledge transfer across generations of researchers to generate trained human resources that will allow these studies to continue in each country in the future.

In Guatemala, three million people are at risk of contracting cutaneous leishmaniosis, primarily in the northern regions. Despite this alarming epidemiological situation, few faunistic studies of phlebotomine sand flies have been conducted in this country, which is the most populous in Central America. An entomological survey of phlebotomine sand flies was carried out from March to September, 2018 in rural, mountainous, and forested areas of six northern Guatemalan departments with active transmission of human leishmaniosis: Petén, Huehuetenango, Quiché, Alta Verapaz, Izabal, and El Progreso. CDC miniature light traps were deployed in and around homes with recent cases of leishmaniosis in children under 10 years of age. A total of 2,605 specimens of sand flies were captured and identified, belonging to three subtribes, nine genera, and 14 species (13 of which were able to be determined), with a balanced sex ratio of 0.95 males per each female. Lutzomyia longipalpis was the most abundant species in the survey, accounting for 62.61% of the total catches; however, this species was restricted to El Progreso and Huehuetenango, with Huehuetenango having the highest capture percentage (55.54%). This vector was predominantly found outdoors, mostly in extra-domicile areas (62.29%). The male/female ratio for this species was 1.94. This study, and the entomological data we present, can aid in enhancing vector control interventions in these northern departments, thereby decreasing the incidence of leishmaniosis in humans.

Nematocera are a suborder of Diptera which historically influenced human history more than any other arthropod group. Four families show a hematophagous behaviour, one being solenophagous (Culicidae), feeding directly on blood vessels, and three being telmophagous (Ceratopogonidae, Psychodidae, and Simuliidae), feeding on blood which pools at the site where their mouthparts have formed a laceration. Although mosquitoes rank first in importance, the telmophagous are also of great interest. Objectives: to update the status of these nematocerans through a transdisciplinary approach, reviewing the main characteristics of each family, the situation of the main vector-borne diseases transmitted by them in the country, especially during the 21st century, and the most relevant species or species groups from a medical and veterinary perspective. Methods: a literature search of databases was conducted and supplemented by browsing specialized journals and citation searching. Results were reviewed and filtered. Results: to date, 84 species of biting midges (Ceratopogonidae), 13 species of sand flies (Psychodidae), and 53 species of black flies (Simuliidae) have been reported in Spain. Culicoides imicola and the Obsoletus complex stand out as the most important biting midges, as they are incriminated in the transmission of bluetongue and Schmallemberg virus; Phlebotomus perniciosus and Phlebotomus ariasi are the vectors of Leishmania infantum; and Simulium erythrocephalum and the Ornatum complex cause the greater part of nuisance and bites to humans in Spain. Conclusions: there is a need to increase research capacity in Spain in order to address several health challenges arising from the presence of telmophagous Nematocera in particular, and of blood-sucking atropods in general.

Los simúlidos o moscas negras son una familia de dípteros en creciente estudio en España, debido a su interés como bioindicadores de la calidad del medio acuático y a su impacto médico-veterinario. Su estudio es limitado en las comunidades autónomas que conforman la región cantábrica, y en especial en el País Vasco, donde apenas existen trabajos sobre su ecología y descripción de las especies presentes. Se muestrearon las fases inmaduras de los simúlidos durante la primavera de 2021 en ocho cursos de agua ubicados en el núcleo urbano y suburbano de la ciudad de Vitoria-Gasteiz (Álava). Un total de ocho especies de moscas negras fueron identificadas mediante morfología clásica y análisis molecular. A partir del estudio de larvas maduras (n = 379) y de adultos emergidos (n = 351) en el laboratorio, se estimó que el grupo Simulium (Simulium) ornatum (S. intermedium, S. ornatum s.l. y S. trifasciatum) fue el conjunto de especies mayoritario, seguido del subgénero Wilhelmia (S. equinum y S. lineatum), S. (Boophthora) erythrocephalum, S. (Eusimulium) rubzovianum y Prosimulium (Prosimulium) tomosvaryi. Simulium ornatum s.l. y S. rubzovianum se capturaron en la mayoría de los cursos de agua, mientras que el resto de especies tuvieron una distribución más restringida. La riqueza de especies en los cursos de agua varió entre una y siete especies. Los sustratos de fijación más recurrentes por las fases inmaduras fueron los helófitos Typha sp. y Scirpus sp. Los simúlidos fueron más abundantes durante el primer periodo de captura. Este trabajo aporta las primeras citas de la familia Simuliidae para el País Vasco, incorpora imágenes de interés de los principales caracteres diagnósticos de larvas, pupas y adultos de las especies más abundantes, y discute sucintamente los resultados obtenidos en relación a la problemática taxonómica existente en el grupo S. ornatum.
