Abstract Cambodia’s goal to eliminate malaria by 2025 is challenged persistent transmission in forest and fringe areas, where people are exposed Anopheles mosquito bites during the day night. Volatile pyrethroid spatial repellents (VPSRs) insecticide-treated clothing (ITC) could address these gaps. This study evaluated outdoor application of one passive transfluthrin-based VPSR, four etofenprox-ITCs paired with a picaridin topical repellent, combination VPSR ITC against wild landing...
The effectiveness of vector-control tools is often assessed by experiments as a reduction in mosquito landings using human landing catches (HLCs). However, HLCs alone only quantify single characteristic and therefore do not provide information on the overall impacts intervention product. Using data from recent semi-field study which used time-stratified HLCs, aspiration non-landing mosquitoes, blood feeding, we suggest Bayesian inference approach for fitting such to stochastic model. This...
Malaria has been Ethiopia's predominant communicable disease for decades. Following the catastrophic malaria outbreak in 2003⁻2004, Federal Ministry of Health (FMoH) took drastic public health actions to lower burden malaria. The FMoH achieved significant declines mortality and incidence, recently declared its objective achieve elimination low transmission areas Ethiopia by 2020. However, while overall prevalence decreased, unpredictable outbreaks increasingly occur irregularly regions...
Abstract Background Although the Republic of Namibia has significantly reduced malaria transmission, regular outbreaks and persistent transmission impede progress towards elimination. Towards an understanding protective efficacy, as well gaps in protection, associated with long-lasting insecticidal nets (LLINs), human Anopheles behaviors were evaluated parallel three endemic regions, Kavango East, Ohangwena Zambezi, using Entomological Surveillance Planning Tool to answer question: where...
The mosquito landing rate measured by human catches (HLC) is the conventional endpoint used to evaluate impact of vector control interventions on human-vector exposure. Non-exposure based alternatives HLC are desirable minimize risk accidental bites. One such alternative human-baited double net trap (HDN), but estimated personal protection using HDN has not been compared efficacy HLC. This semi-field study in Sai Yok District, Kanchanaburi Province, Thailand, evaluates performance and for...
Background Agricultural worksites are rarely targeted by malaria control programmes, yet may play a role in maintaining local transmission due to workers’ high mobility, low intervention coverage and occupational exposures. Methods A quasi-experimental controlled study was carried out farming cattle herding populations northern Namibia evaluate the impact of package. Eight health facility catchment areas Zambezi Ohangwena Regions were randomised an arm eligible individuals within received...
Abstract Background Cambodia strives to eliminate all species of human malaria by 2025, requiring that foci among forest-exposed populations in remote settings be addressed. This study explores risks amongst groups Mondulkiri and Kampong Speu Provinces, as part a multi-stage on novel mosquito bite prevention tools (Project BITE). Methods A serial cross-sectional survey explored the demographics, housing structure openness, habits, protection from three target groups: forest goers who work...
Background Vector control remains the principal method to prevent malaria transmission and has led significant reductions in incidence across endemic regions. However, such gains have stagnated, underscoring need tailor vector local drivers of transmission. An Entomological Surveillance Planning Tool (ESPT) was designed translate normative guidance into an operational tool that supports cost effective, locally tailored, evidence-based control. To facilitate ESPT implementation, interactive...
Abstract Background Forest-exposed populations remain the last significant, and most difficult to access, high-risk for malaria in Cambodia. Despite availability of long-lasting insecticidal nets (LLINs) and/or hammock (LLIHNs), continued transmission indicates gaps protection. This study aimed identify these among forest-exposed individuals Plasmodium falciparum hotspots two provinces Cambodia, using entomological assessments human behaviour observations (HBOs). Methods Anopheles bionomic...
Abstract Background Malaria, a mosquito-borne disease, is serious public health issue globally and leading cause of morbidity mortality in many developing countries worldwide. Cambodia the last stages malaria elimination aims to eliminate all species human by 2025. Despite tremendous progress, eliminating has proven be challenging due pockets residual transmission high-risk populations sustained untreated asymptomatic reservoirs. Understanding extent reservoirs ‘last-mile’ communities such...
Abstract Background Although most of Panamá is free from malaria, localized foci transmission persist, including in the Guna Yala region. Government-led entomological surveillance using an Entomological Surveillance Planning Tool (ESPT) sought to answer programmatically relevant questions on local drivers and gaps protection guide vector control decision-making.

Abstract Cambodia’s goal to eliminate malaria by 2025 is challenged persisting transmission in the country’s forest and fringe areas. People living in, or traveling forest, are exposed vector bites during day due Anopheles daytime biting; night, low bed net use open sleeping structures. Volatile pyrethroid spatial repellents (VPSRs), insecticide treated clothing (ITC) may help address these gaps protection. In this field study authors evaluated outdoor application of one passive,...
Abstract Background The protective effectiveness of vector control in malaria relies on how the implemented tools overlap with mosquito species-specific compositions and bionomic traits. In Ethiopia, targeted entomological data enabling strategic decision-making are lacking around high-risk migrant worker camps lowlands resident communities highlands—resulting suboptimal strategies for both populations. This study investigates spatial temporal behavior, generating baseline evidence that will...
Abstract Background The Greater Mekong Subregion (GMS) aims to eliminate all human malaria by 2030 and is making substantial progress toward this goal, with increasingly confined forest foci. These transmission foci are predominantly inhabited ethnic minorities, local populations, rural mobile migrant populations working in mining agriculture. recommendations of the World Health Organization (WHO) on elimination states that small population groups which constitute a large proportion...
Abstract Background Though most of Panamá is free from malaria, localized foci transmission persist, including in the Guna Yala region. Government-led entomological surveillance using an planning tool (ESPT) sought to answer programmatically-relevant questions that would enhance understanding both local drivers and gaps protection result persisting malaria guide vector control decision-making.

Pyrethroid-based indoor residual spraying (IRS) and long-lasting insecticidal nets (LLINs) have been employed as key vector control measures against malaria in Namibia. However, pyrethroid resistance Anopheles mosquitoes may compromise the efficacy of these interventions. To address this challenge, World Health Organization (WHO) recommends use piperonyl butoxide (PBO) LLINs areas where is confirmed to be mediated by mixed function oxidase (MFO).
Abstract Background Ethiopia continues to grapple with a persistent malaria burden, characterized by ongoing transmission and recurrent outbreaks. Human behavior influences both exposure the effectiveness of vector interventions, complicating control efforts. Implementing tailored strategies that account for complex interplay between human activities remains challenge in high- low-transmission areas Ethiopia, particularly vulnerable highland populations temporary labor migrants, due lack...

Abstract Every day, hundreds of mosquito surveys are carried out around the world to inform policy and management decisions on how best reduce or prevent burden mosquito-borne disease nuisance. These usually time consuming expensive. Mosquito surveillance is essential component vector control. However, often with a limited if not without quantitative assessment sampling effort which can results in underpowered overpowered studies, certainly studies when power analyses assuming independence...
Wyeomyia (Wyeomyia) mitchellii (Theobald) (Diptera: Culicidae) was recovered for the first time on Guam, United States of America, in 2017. Larval specimens were collected from water-filled axils bromeliads during a larval survey carried out residential neighborhood Chalan Pago/Ordot area. Native to New World, Wy. has likely made its way Pacific Islands through possibly illegal import ornamental bromeliads. While this mosquito does not represent significant threat public health, finding...
