“…The timing of wide area ultra-low volume spatial applications of aerosolized pesticides must take into account the behavior of each species’ peak host-seeking activity time or the insecticide droplets will not come into contact with the mosquitoes [ 61 ]. In Florida, most ultra-low volume spatial applications occur at dusk to target crepuscular species [ 24 ]. However, not all vector and nuisance species are crepuscular.…”

“…Malathion is considered “slightly hazardous”, while naled is a corrosive agent and “extremely hazardous”. Although organophosphates have an extremely high efficacy, adulticiding using organophosphates is only performed after extensive consideration and contemplation by FMCDs due to their toxicity [ 24 ]. As such, their implementation is limited to reduce human exposure.…”

“…Early approaches to mosquito control included dynamite ditching, diking, and dewatering. By the mid-1940s, the use of aerosolized chemical insecticides such as dichloro-diphenyl-trichloroethane (DDT) and temephos became increasingly common methods of mosquito control [ 24 ]. However, it became apparent that chemical control alone was not enough to mitigate mosquito populations, and growing concerns of insecticide resistance, toxicity, nontarget effects, and environmental persistence resulted in calls for innovation and new technologies.…”

Mosquito Control Priorities in Florida—Survey Results from Florida Mosquito Control Districts

et al. 2021

Florida lies within a subtropical region where the climate allows diverse mosquito species including invasive species to thrive year-round. As of 2021, there are currently 66 state-approved Florida Mosquito Control Districts, which are major stakeholders for Florida public universities engaged in mosquito research. Florida is one of the few states with extensive organized mosquito control programs. The Florida State Government and Florida Mosquito Control Districts have long histories of collaboration with research institutions. During fall 2020, we carried out a survey to collect baseline data on the current control priorities from Florida Mosquito Control Districts relating to (1) priority control species, (2) common adult and larval control methods, and (3) major research questions to address that will improve their control and surveillance programs. The survey data showed that a total of 17 distinct mosquito species were considered to be priority control targets, with many of these species being understudied. The most common control approaches included truck-mounted ultra-low-volume adulticiding and biopesticide-based larviciding. The districts held interest in diverse research questions, with many prioritizing studies on basic science questions to help develop evidence-based control strategies. Our data highlight the fact that mosquito control approaches and priorities differ greatly between districts and provide an important point of comparison for other regions investing in mosquito control, particularly those with similar ecological settings, and great diversity of potential mosquito vectors, such as in Florida. Our findings highlight a need for greater alignment of research priorities between mosquito control and mosquito research. In particular, we note a need to prioritize filling knowledge gaps relating to understudied mosquito species that have been implicated in arbovirus transmission.

“…In relation to the mosquitoes, it is well known that factors such as rainfall, temperature, and humidity influence malaria transmission because they affect the development and survival of both the mosquitoes and the parasites that they harbor [9]. Moreover, Richardson et al [10] underlined that natural water sources, such as ponds or waterholding containers, are preferred as larval developmental sites and are potential mosquito breeding areas. Although there are some attempts to apply remote sensing and machine learning techniques to model mosquito distribution and abundance, recent works indicate the scarcity of works related to the application of remote sensing and machine learning in epidemiologic studies [11].…”

Applying Remotely Sensed Environmental Information to Model Mosquito Populations

et al. 2021

Vector borne diseases have been related to various environmental parameters and environmental changes like climate change, which impact their propagation in time and space. Remote sensing data have been used widely for monitoring environmental conditions and changes. We hypothesized that changes in various environmental parameters may be reflected in changes in mosquito population size, thus impacting the temporal and spatial patterns of vector diseases. The aim of this study is to analyze the effect of environmental variables on mosquito populations using the remotely sensed Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST) obtained from Landsat 8, along with other factors, such as altitude and water covered areas surrounding the examined locations. Therefore, a Multilayer Perceptron (MLP) Artificial Neural Network (ANN) model was developed and tested for its ability to predict mosquito populations. The model was applied in NE Greece using mosquito population data from 17 locations where mosquito traps were placed from June to October 2019. All performance metrics indicated a high predictive ability of the model. LST was proved to be the factor with the highest relative importance in the prediction of mosquito populations, whereas the developed model can predict mosquito populations 13 days ahead to allow a substantial window for appropriate control measures.

Aedes aegypti L. Mosquito is the only vector of Dengue Hemorrhagic Fever (DHF). The chemical-based control agents have a negative effect if used for a long time. Therefore, this research focused on finding the natural agent that may act as an adulticide, like Bintaro (Cerbera manghas L.). Bintaro leaves contain active compounds such as cerberin (one of the alkaloids), flavonoids, tannins, steroids, and saponins that have a mortality effect on mosquitoes. The study was to determine the effectiveness of Bintaro leaves extract as an adulticide against Aedes aegypti mosquitoes. This experimental research uses the posttest-only control group design and uses Ae. Aegypti mosquito aged 3-5 days as the sample. There were seven different concentrations of Bintaro leaves extract as a treatment, namely 300 ppm, 350 ppm, 400 ppm, 450 ppm, 500 ppm, 550 ppm, and 600 ppm. The method used in this research is using a 250 ml Duran bottle. The results of the study showed that the Bintaro leaves extract at a concentration of 600 ppm was more effective against the mortality of Ae. Aegypti, but not significantly different from the 400 ppm, 450 ppm, 500 ppm, and 550 ppm treatments. And the LC50 probit regression analysis was 455.602 ppm, and the LC90 value was 1735.956 ppm.
