“…This essential oil may be of great value in complementing other compounds which are losing their efficacy against vectors, such as pyrethroids and others which are considered none-biodegradable and environmental pollutants such as 1,1,1-trichloro-2,2-bis( p -chlorophenyl) ethane (DDT) [ 33 ]. From other studies, some phytochemicals have acted as general toxicants against adult as well as larval stages of mosquitoes, while others interfere with growth and development (growth inhibitors) or with reproduction (chemosterilent) or produce olfactory stimuli acting as repellent or attractant [ 34 ].…”

Background: The increasing status of insecticide resistant mosquitoes in sub-Saharan Africa is a threatening alert to the existing control efforts. All sibling species of An. gambiae complex have evolved insecticide resistance in wild populations for different approved classes of the insecticides currently in use in the field. An alternative compound for vector control is absolutely urgently needed. In this study, the larvicidal activity and chemical composition of the Cinnamomum osmophloeum leaf essential oils were investigated.

“…While policymakers generally assume public support for malaria control programmes due to these manifest disease reduction benefits, there has been a persistent debate in academic and policy communities about the sustainability of continuing these status quo control methods indefinitely [ 3 – 5 ]. This question of sustainability often centres on the threat of insecticide resistance [ 6 , 7 ], as well as the potential long-term health and environmental impacts from prolonged exposure to insecticides in the context of these vector control methods [ 8 – 10 ]. There is a growing evidence base analysing the biological dynamics involved in the spread of insecticide resistance [ 11 , 12 ] and evaluating its operational impacts on vector control programmes [ 13 – 15 ].…”

Household perceptions and subjective valuations of indoor residual spraying programmes to control malaria in northern Uganda

et al. 2016

BackgroundInsecticide-based tools remain critical for controlling vector-borne diseases in Uganda. Securing public support from targeted populations for such tools is an important component in sustaining their long-run effectiveness. Yet little quantitative evidence is available on the perceived benefits and costs of vector control programmes among targeted households.MethodsA survey was administered to a clustered random sample of 612 households in Gulu and Oyam districts of northern Uganda during a period of very high malaria transmission and following a pilot indoor residual spray (IRS) programme. A discrete choice experiment was conducted within the survey, in which respondents indicated their preferences for different IRS programmes relative to money compensation in a series of experimentally controlled, hypothetical choice sets. The data were analysed using conditional logit regression models to estimate respondents’ willingness to accept (WTA) some amount of money compensation in lieu of foregone malaria risk reductions. Latent class models were used to analyse whether respondent characteristics predicted WTA.ResultsAverage WTA is estimated at $8.94 annually for a 10 % reduction in malaria risk, and additional co-benefits of IRS were estimated to be worth on average $54–$56 (depending on insecticide type) per round of IRS. Significant heterogeneity is observed: Four in five household heads in northern Uganda have high valuations for IRS programmes, while the remaining 20 % experience costly side effects of IRS (valued at between $2 and $3 per round). Statistically significant predictors of belonging to the high-value group include respondent gender, mean age of household members, participation in previous IRS, basic knowledge of mosquito reproduction, and the number of mosquito nets owned. Proxies for household income and wealth are not found to be statistically significant predictors of WTA.ConclusionsThis study suggests that the majority of people in areas of high malaria transmission like northern Uganda place a high value on vector control programmes using IRS. However, there is significant heterogeneity in terms of the perceived side effects (positive and negative). This has implications for sustaining public support for these programmes in the long-term.Electronic supplementary materialThe online version of this article (doi:10.1186/s40249-016-0190-1) contains supplementary material, which is available to authorized users.
