“…In Pakistan, nets provided added protection against P. vivax and P. falciparum in refugee camps where IRS was conducted [56]. However, other studies observed no additional benefit from the combination compared to one intervention alone [46],[57],[58].…”

“…Consequently, increased attention has been given for development of vector control strategies which aim to reduce mosquito population numbers or their contact with potential human host, with some methods proving highly effective in lowering the incidence of such ailments in many affected areas (Beier et al, 2008; Enayati and Hemingway, 2010). However, the efficacy of current vector control methods is mostly limited to low-transmission environments, such as arid locations or isolated islands (Bhattarai et al, 2007; Kleinschmidt et al, 2007; Keating et al, 2011), whereas they have negligible or no impact in areas where entomological inoculation rates (EIRs) are more substantial (Beier et al, 1999; McKenzie et al, 2001; Shaukat et al, 2010). These shortcomings can be attributed to several factors.…”

Attractive toxic sugar bait (ATSB) is a highly effective method which targets mosquitoes based on their sugar foraging behavior, by presenting baits of attractive compounds in combination with sugar and oral toxin to local mosquito populations. Environmental concerns and insecticide selection-pressure have prompted investigations of novel, ecologically-harmless substances which can be used as insecticides. This study examined the efficacy of microencapsulated garlic-oil as the oral toxin component of ATSB for controlling Anopheles sergentii populations inhabiting desert-surrounded wetlands in Israel. ATSB solution containing 0.4% encapsulated garlic oil was applied to local vegetation around a streamlet located in the lower Jordan Valley. To determine the propensity of bait ingestion, and assess the potential ecological impact of the method, mosquito and non-target specimens were collected and tested for the presence of natural plant- or attractive sugar bait (ASB)-derived sugars. Over the experimental period, biting-pressure values in the ATSB treatment site decreased by 97.5%, while at the control site, treated with non-toxic ASB, no significant changes were observed. Approximately 70% of the mosquitoes collected before both treatments, as well as those captured following the application of ASB at the control site, were found to have ingested sugar prior to capture. Non-target insects were minimally affected by the treatment when ATSB was applied to foliage of non-flowering plants. Of the non-Diptera species, only 0.7% of the sampled non-target insects were found to have ingested ASB-solution which was applied to green vegetation, compared with 8.5% which have foraged on ASB-derived sugars applied to flowering plants. Conversely, a high proportion of the non-target species belonging to the order Diptera, especially non-biting midges, were found to have ingested foliage-applied ASB, with more than 36% of the specimens collected determined to have foraged on bait-derived sugars. These results prove that food-grade, EPA-exempt microencapsulated garlic oil is a highly effective insecticide which can be utilized for mosquito population control. The relatively short half-life of this active ingredient makes it a suitable for use in areas where repeated application is possible, limiting the accumulation of deleterious compounds and ensuring minimal environmental impact when applied in accordance with label recommendations.

“…In Tanzania, the malaria disease was responsible for up to one-third of deaths, in children under the age of 5 years and for more than one-fifth of deaths, in pregnant women (3). According to the world health organization (WHO) Global Malaria Program, three important interventions, including diagnosis and treatment of malaria cases with effective medications, insecticide-treated nets (ITNs) distribution and indoor residual spraying (IRS), are imperative for the control and prevention of residents from malaria (4)(5)(6).…”

Indoor Residual Spraying Coverage and Acceptability Rates to Control Malaria and the Householders’ Reasons of Acceptance or Rejection of Spraying, in South-East of Iran

et al. 2015

Background: Indoor residual spraying (IRS), as one of the malaria control techniques, requires high spraying coverage and acceptance rate by householders, to be effective. Objectives:The main aim of the study was to assess the spraying acceptability and coverage rates in relation to acceptance and rejection reasons of the IRS program. Also, the householders' perception about IRS benefits and satisfaction with the malaria prevention and knowledge of transmission pathways were estimated. Materials and Methods: A cross-sectional survey was performed in endemic districts of Sistan-and Baluchistan province (south-east of Iran), in two years of 2013 and 2014. Data were collected by a validated questionnaire, through interviewing 834 household heads that were randomly selected from 40 villages, of four malarial sub-districts. To analyze the data, chi-squire test was performed, by using SPSS software (Version 18). The significance level was set at P ≤ 0.05. Results: A total of 834 households' heads were interviewed, with the mean age of 39.5 ± 15.4 years, 73.3% males and 26.7% females. The main sources of information, concerning IRS, were health care workers (51.4%). The IRS coverage and acceptance rates were 96.5% and 94%, respectively. Of the total number of participants, 95.3% of householders associated the disease transmission with mosquito bites and reported the use of insecticidal bed nets (90%) and IRS (74.1%), as important ways of malaria prevention. Conclusions:The study showed that IRS coverage and acceptance rates were relatively high, which is essential in reaching malaria elimination. The information on malaria transmission and knowledge prevention measures showed that householders were, to a certain extent, familiar with the malaria control activities conducted by the health care service.
