Special Issue Information

Dear Colleagues,

Mosquito-borne diseases represent a complex public health challenge that intersects human health, animal health, and ecosystem dynamics. These diseases not only involve direct transmission between mosquito vectors and humans but also incorporate wildlife that can perpetuate and intensify pathogen presence in natural reservoirs. Human exposure to these pathogens typically occurs via bites from infected mosquitoes. While vaccines provide a line of defense against some of these diseases, many control strategies focus primarily on minimizing the interaction between humans and infectious mosquito vectors through measures such as bed nets and chemical vector control.

Within the One Health framework, this Special Issue aims to cover a range of topics, including disease surveillance, integrated analysis and modelling, innovative mosquito control techniques, and the assessment of intervention effectiveness, including how they may need to be adapted for climate change. Furthermore, acknowledging the often-limited resources available to control practitioners, this Special Issue will also focus on strategies for resource prioritization to maximize impacts on public health. Through a One Health lens, we invite contributions that not only address these challenges but also emphasize integrated approaches that consider the interconnected health of humans, animals, and our shared environment.

Aedes albopictus and Aedes japonicus are invasive mosquito species that are causing great public concern. Aedes albopictus have successfully spread in Croatia, established in both the coastal and continental parts of the country, while Aedes japonicus is invading temperate climate areas. The invasive Aedes species are particularly attracted to the black plastic water containers and flower vases in cemeteries where they oviposit their eggs. Therefore, monitoring of this species was carried out in 12 cemeteries in Zagreb, using ovitraps with masonite strips as a substrate for oviposition. The monitoring was carried out from 2017 to 2020. The traps were inspected and the substrate was replaced every two weeks. This study showed that these two invasive species were present and very abundant in the cemeteries. In the case of Ae. albopictus, a higher population density and a greater number of occupied cemeteries were detected. This species was identified in all 12 cemeteries. Aedes albopictus was identified as the dominant species at all study sites. The spread of Ae. japonicus increased during 2018 in comparison to the previous year. Although this species was present in approximately 9% of the ovitraps, the observed population remained consistent throughout the course of the study. The findings indicate that cemeteries can be considered as significant public health hotspots, as the invasive Aedes mosquitoes tend to develop and reproduce in such environments. Consequently, the mosquito population of these two invasive species may only be reduced by applying integrated mosquito management measures, focused on the education of citizens. Full article

Citizen science resources have had great relevance in community educational intervention, fostering interest in ecological research projects. This study investigated the influence of the application of multimedia didactic resources focused on citizen science and analysis of sociodemographic variables to improve the levels of ecological knowledge about mosquito-borne diseases. For this, a probabilistic sample of 172 participants from an urban sector in southwestern Colombia was selected. A multimedia didactic material was designed for the educational intervention and evaluated by means of pretest and posttest. To assess whether the educational intervention was statistically significant, the data were processed with statistical inference to determine the influence of various variables (gender, age, marital status, schooling, and occupation) on each person’s ecological knowledge. The findings showed a significant increase in the knowledge levels of the participants. The marital status variable (married and cohabiting) significantly influenced ecological knowledge. These participants are more likely to obtain high knowledge, associated with the prevention of their family environment. This study demonstrated that multimedia didactic strategies are an important factor to take into account in the structuring of environmental education and citizen science projects. For future research, it is suggested to deepen the relationship between sociodemographic variables and ecological knowledge. Full article

The growing resistance of Aedes aegypti (L.) to conventional insecticides presents a major challenge in arbovirus control, necessitating the exploration of alternative insecticidal chemistries. Spiromesifen, derived from spirocyclic tetronic acids, is widely used against agricultural pests and is crucial in resistance management due to its unique lipid synthesis inhibition. This study evaluates the insecticidal activity of spiromesifen against temephos-resistant Ae. aegypti populations, focusing on larval body weight, volume, biochemical composition, and adult female reproductive potential. Spiromesifen demonstrated effective larvicidal activity, significantly reducing adult emergence. Resistance to spiromesifen was not observed, with resistance ratios (RR50, RR90) ranging from 0.36- to 3.31-fold. Larvae exposed to LC50 showed significant reductions in body weight and volume, and reduced carbohydrate, lipid, and protein contents. Enhanced catalase activity and malondialdehyde levels indicated increased oxidative stress and lipid peroxidation, highlighting its effects on lipid metabolism. Spiromesifen also exhibited sterilizing effects, significantly reducing fecundity and fertility in adult females, thereby impacting Ae. aegypti reproductive capacity. These findings highlight the potential of spiromesifen as a component of integrated vector management strategies, especially in regions with prevalent insecticide resistance in Ae. aegypti, serving as an effective larvicide and impacting adult reproductive outcomes.

Programs to control viruses transmitted by mosquitoes requires the implementation of surveillance tools. Over the past decade, Flinders Technology Associates (FTA®) cards, which preserve nucleic acids, have emerged as an innovating surveillance system for collecting arboviruses expectorated during mosquito sugar feeding. In this study, we evaluate the survival rates of two strain of Aedes aegypti (New Orleans (NO) and Cayenne (CAY)) in the laboratory after exposing to either honey-impregnated FTA® cards or untreated filter paper (UFP) card. Experimental exposure of mosquitoes to FTA® cards during sugar feeding significantly negatively impacted their survival, as compared to untreated filter paper. The median survival time was 2 days (95% confidence interval [CI] 1 day, 3 days) for mosquitoes exposed to FTA cards from strain NO and 3 days (95% CI 2 days, 3 days) for mosquitoes exposed to FTA cards from strain CAY. Mosquitoes exposed to UFP did not survive until the end of the experiment (4 days for strain NO and 7 days for strain CAY). Although this finding does not preclude the use of FTA® cards in surveillance, it is crucial to consider and incorporate this factor into study designs. Full article
