“…Even so, the insecticidal effects of natural insecticides are generally short, so that the application needs to be repeated frequently (Trewin et al, 2017). One of the alternative methods to reduce mosquito vector of DHF is to use the biological vector control method by using larvivorous fish (Paiva et al, 2014;MOH, 2010).…”

Biological vector control by using larvivorous fish will be beneficial in reducing Aedes aegypti population, hence reducing risk of dengue virus transmission. It is important to select the larvivorous fish according to its digestive organ.Current study aimed to investigate the predation potential among the fish species and to identify the influence of the digestive tract length of the fish related to their predation potential. The research was an analytical observational study with post-test only design. Third stage larvae of Aedes aegypti were used as preys for tilapia (Oreochromis niloticus), common carper (Cyprinus carpio), and guppy (Poecillia reticulata). In association with their digestive tract length, predation potential of tilapia, common carper, and guppy showed statistical differences (P<0.05). Tilapia demonstrated highest predation of the larvae, followed by common carper and guppy. There are associations between difference in shapes of mouth and intestines, mouth width, intestinal length, and predation potential of these fish species. Current study results showed possible associations between digestive tract length of tilapia, common carper and guppy and predation potential on Aedes aegypti larvae, allowing these fish species to be used inbiological control of Aedes aegypti.

“…Results show an increase in mosquito mortality of 80-90%. 39 However, it was observed that a research carried out in Madeira Island, using the same strategy mentioned above, did not obtain such satisfactory results, since there was no considerable reduction in the number of Aedes aegypti females, however, there was a reduction in the number of eggs laid in the ovitraps. 59 It has been identified that the use of entomopathogenic fungus Metarhizium anisopliae, in association with neem oil, is capable of infecting from the egg to the adult phase of the mosquito.…”

Objetivo: sintetizar as ações desenvolvidas para o enfrentamento ao Aedes aegypti no contexto brasileiro. Método: trata-se de um estudo bibliográfico, descritivo, tipo revisão integrativa. Realizou-se a busca na MEDLINE, LILACS e BDENF. Utilizaram-se os filtros: texto completo disponível; idioma (português, inglês e espanhol), tipo de documento (artigo) e ano de publicação (2013-2018). Organizou-se o processo de definição e seleção dos estudos por meio do fluxograma PRISMA. Utilizou-se o software IRAMUTEQ para o processamento e a análise dos dados. Analisaram-se os dados a partir da Classificação Hierárquica Descendente e da nuvem de palavras. Resultados: selecionaram-se 31 estudos. Originaram-se seis classes com as seguintes estratégias: fungos entomopatogênicos; peixes larvívoros; Wolbachia pipientis; técnicas RILD e SIT; inseticidas botânicos; larvicidas Diflubenzuron e Deltramina; Piriproxifeno; monitoramento tecnológico; visitas regulares pelo ACS e ACE; abordagem ecossaúde; MIV e campanhas. Conclusão: conclui-se que há uma variedade de estratégias de enfrentamento às arboviroses e o quão são necessários o aperfeiçoamento e o desenvolvimento de técnicas inovadoras para o controle deste agravo.

Method: this is a bibliographic, descriptive, integrative review study. The search was performed at MEDLINE, LILACS and BDENF. The filters were used: full text available; language (Portuguese, English and Spanish), type of document (article) and year of publication (2013-2018). The process of definition and selection of studies was organized through the PRISMA flowchart. IRAMUTEQ software was used for data processing and analysis. Data was analyzed from Descending Hierarchical Classification and word cloud. Results: 31 studies were selected. Six classes originated with the following strategies: entomo-pathogenic fungi; larval fish; Wolbachia pipientis; RILD and SIT techniques; botanical insecticides; larvicides Diflubenzuron and Deltramine; Pyriproxyfen; technological monitoring; regular visits by ACS and ACE; eco-health approach; MIV and campaigns. Conclusion: it is concluded that there are a variety of strategies for coping with arboviruses and how much the improvement and development of innovative techniques for the control of this disease are necessary.

“…Other useful strategies that can reduce the development of insecticide-resistant mosquitoes target the larvae stage through the use of larvicides such as larviciding with larvivorous fish and bacterial larvicide [40][41][42][43][45][46][47][48].…”

“…For simplicity, we assume that the use of bednets reduces the contact between mosquitoes and humans and that the mosquito population is reduced by the mosquito-reduction strategies (larvicides and adulticides), which we assume in this case chemical-based insecticides. However, there are other environmental friendly larvaciding methods that can be used to target the larvae stage of the mosquitoes, such as larvivorous fish which prey on the larvae [40][41][42][43][44] and bacterial larvicide which causes the mosquitoes to starve to death once they ingest the spores of the bacterial larvicide [45][46][47][48]. In a future study, we will incorporate the insecticide capacity of the bednets [49] and the actions and kinetics of these larvacide methods.…”

Optimal Control and Temperature Variations of Malaria Transmission Dynamics

Malaria is a Plasmodium parasitic disease transmitted by infected female Anopheles mosquitoes. Climatic factors, such as temperature, humidity, rainfall, and wind, have significant effects on the incidence of most vector-borne diseases, including malaria. The mosquito behavior, life cycle, and overall fitness are affected by these climatic factors. This paper presents the results obtained from investigating the optimal control strategies for malaria in the presence of temperature variation using a temperature-dependent malaria model. The study further identified the temperature ranges in four different geographical regions of sub-Saharan Africa, suitable for mosquitoes. The optimal control strategies in the temperature suitable ranges suggest, on average, a high usage of both larvicides and adulticides followed by a moderate usage of personal protection such as bednet. The average optimal bednet usage mimics the solution profile of the mosquitoes as the mosquitoes respond to changes in temperature. Following the results from the optimal control, this study also investigates using a temperature-dependent model with insecticide-sensitive and insecticide-resistant mosquitoes the impact of insecticide-resistant mosquitoes on disease burden when temperature varies. The results obtained indicate that optimal bednet usage on average is higher when insecticide-resistant mosquitoes are present. Besides, the average bednet usage increases as temperature increases to the optimal temperature suitable for mosquitoes, and it decreases after that, a pattern similar to earlier results involving insecticide-sensitive mosquitoes. Thus, personal protection, particularly the use of bednets, should be encouraged not only at low temperatures but particularly at high temperatures when individuals avoid the use of bednets. Furthermore, control and reduction of malaria may be possible even when mosquitoes develop resistance to insecticides.
