Indoor residual spraying (IRS) and long-lasting insecticidal nets (LLINs) remain the cornerstones of malaria vector control. However, development insecticide resistance its implications for operational failure preventative strategies are concern. The aim this study was to characterize among Anopheles arabiensis populations in Ethiopia describe temporal spatial patterns between 2012 2016. Between 2016, status An. assessed annually during long rainy seasons sites from seven nine regions...
The emergence and spread of insecticide resistance in the major African malaria vectors Anopheles gambiae s.s. arabiensis may compromise control initiatives based on insecticide-treated nets (ITNs) or indoor residual spraying (IRS), thus threaten global elimination strategy.We investigated pyrethroid four populations An. from south-western Ethiopia then assessed bio-efficacy six World Health Organization recommended long lasting insecticidal (LLINs) using these populations.For all...
The emergence and spread of insecticide resistance in the major African malaria vectors Anopheles gambiae (s.s.) An. arabiensis may compromise current vector control interventions threatens global elimination efforts. Insecticide was monitored several study sites Ethiopia from 2013 to 2015 using papers impregnated with discriminating concentrations DDT, deltamethrin, bendiocarb, propoxur, malathion, fenitrothion pirimiphos-methyl, following WHO susceptibility test procedure. Mosquitoes...
Abstract Background Integrated vector management (IVM) remains a key strategy in the fight against vector-borne diseases including malaria. However, impacts of should be regularly monitored based on feedback obtained through research. The objective this study was to assess impact IVM for malaria control Botor-Tolay district, southwestern Ethiopia after three years (2016–2018) implementation. Method Prior implementation IVM, survey socio-demographic, burden, and communities’ perception...
Abstract Background Indoor Residual Spraying (IRS) and Long-Lasting Insecticidal nets (LLINs) are major malaria vector control tools in Ethiopia. However, recent reports from different parts of the country showed that populations Anopheles arabiensis , principal vector, have developed resistance to most families insecticides recommended for public health use which may compromise efficacy both these key interventions. Thus, this study evaluated DDT IRS LLINs against resistant An. using...
Continuous monitoring of vector species composition, abundance, dynamics, feeding pattern, and host finding strategy is the base to determine when, what, how control should be implemented. Thus, this study was conducted assess entomological parameters anopheline mosquitoes in nine villages Seka district, southwestern Ethiopia, from June December 2012. Mosquito collection carried out selected households each using light trap catches Differences mean mosquito density, parity rates before,...
In Ethiopia, malaria incidence has significantly reduced in the past decade through combined use of conventional vector control approaches and treatment using antimalarial drugs. However, sustainability this achievement is threatened by shift biting resting behaviors emergence insecticide resistance primary vector. Therefore, continuous monitoring behaviour mosquitoes different sentinel sites crucial to design effective prevention methods local context. Entomological investigations were...
Among the factors affecting effectiveness of malaria control is poor knowledge entomologic drivers disease. We investigated anopheline populations as part a baseline study to implement house screening windows and doors supplementary tool towards elimination in Jabi Tehnan district, Amhara Regional State Ethiopia. The samples were surveyed monthly using CDC light traps between June 2020 May 2021. Mosquito trap density (< 3 mosquitoes/trap) was low, however, with high overall Plasmodium...
Background & objectives: Despite a tremendous expansion in the financing and coverage of malaria control programmes, disease continues to be global health threat. This study was conducted assess entomological parameters anopheline mosquitoes, viz. species composition, abundance, longevity, behaviour infectivity rates Kersa district, Jimma zone, southwestern Ethiopia. Methods: Mosquito collection carried out from each selected household nine villages using CDC light-traps pyrethrum spray...
Adequate forage availability coupled with favorable and diversified agroclimatic conditions of Ethiopia creates environmental conducive to the growth over 7000 species flowering plants which have supported existence large number bee colonies in country. Despite its potential honey production, contribution apiculture state GDP is far below expectation not well estimated yet. The objective this study was assess community perception beekeeping management constraints central Ethiopia. 384...
Insecticide-based vector control interventions in combination with case management artemisinin-based therapy has reduced malaria incidence and prevalence worldwide. Current methods focus on the primary vectors, Anopheles gambiae sensu lato (s.l.) An. funestus group; however, impact of secondary suspected vectors been either sidelined or received limited attention. Defining susceptibility secondary, species to different parasites time space is essential for efficient elimination programs. The...
PermaNet® 3.0 is a deltamethrin-treated combination long-lasting insecticidal net with the addition of synergist piperonylbutoxide (PBO) on its roof section. It designed to overcome challenge posed by pyrethroid resistant vector populations against mainstream nets impregnated pyrethroids only. The objective this study was determine insecticide resistance status Anopheline and Culicine mosquitoes, evaluate bio-efficacy assess household factors affecting physical integrity after 3 years...
Abstract Afromontane landscapes are typically characterized by a mosaic of smallholder farms and the biodiversity impacts these practices will vary in accordance to local management landscape context. Here, we assess how tropical butterfly diversity is maintained across an agricultural Jimma Highlands Ethiopia. We used transect surveys sample understory communities within degraded natural forest, semi‐managed coffee forest ( SMCF ), exotic timber plantations, open woodland, croplands...
Use of long-lasting insecticidal nets (LLINs), indoor residual spraying (IRS), community-based malaria education, prompt diagnosis and treatment are key programme components prevention control in Ethiopia. However, the effectiveness these interventions is often undermined by various challenges, including insecticide drug resistance, plasticity vectors feeding biting behaviour, certain household factors that lead to misuse poor utilization LLINs. The primary objective this study was document...
Abstract Background The combined application of long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) are commonly used malaria interventions that target Anopheles vectors. Recent studies on the effects house screening (HS) LLINs have demonstrated a reduction in vector densities when combined. In addition, complementary needed to curb co-occurring pest populations which pose menace agricultural crop productivity food security. However, impact mainly centre public health...
Abstract Introduction: The combined application of long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) has led to mixed results (Significant reduction vs no impact) on malaria burden. Other studies have attempted study the effects house screening (HS) LLINs demonstrated a in vector densities when interventions are combined. In addition vectored by mosquitoes, farmers living rural settings face challenges from crop pests, which significantly reduce agricultural...
