This varies among species and is affected by insecticidal irritancy. Exophilic behavior has evolved in certain popu- lations exposed to prolonged spraying programs. Optimum effectiveness of insecticide- treated nets presumably depends on vectors biting at hours when most people are in bed. Time of biting varies among different malaria vector species, but so far there is inconclusive evidence for these evolving so as to avoid bednets. Use of an untreated net diverts extra biting to someone in the same room who is without a net. Understand- ing choice of oviposition sites and dispersal behavior is important for the design of successful larval control programs including those using predatory mosquito larvae. Prospects for genetic control by sterile males or genes rendering mosquitoes harmless to humans will depend on competitive mating behavior. These methods are hampered by the immigration of monogamous, already-mated females.

  • Development of 'Olyset® Net' As a Tool for Malaria Control
    ® Sumitomo Chemical Co., Ltd. Development of ‘Olyset net’ as Environmental Health Division a Tool for Malaria Control Takaaki ITO Sumika Life Tech, Ltd. Takeshi OKUNO Olyset® net is composed of a resin-based fiber that incorporates a synthetic pyrethroid called permethrin to form a mosquito net for malaria vector control. The most important characteristic of Olyset® net is a dynamic release behavior for the permethrin in the fiber. Though a washing removes part of the permethrin from the sur- face of the net, the permethrin migrates from the inside of the fibers to the surface and maintains its efficacy against mosquitoes. In addition, since the fiber itself is tough, the efficacy of an Olyset® net lasts and the net itself can be kept for at least 5 years in Africa. This paper is translated from R&D Report, “SUMITOMO KAGAKU”, vol. 2006-II. Introduction deaths amounts to one million with most of the victims being children under five years of age, so it can be 1.

  • FAQ's About Mosquito Nets
    FAQ’s about mosquito nets How and why do mosquito nets work? The female Anopheles mosquito, which spreads malaria by transmitting the Plasmodium parasite to humans, is nocturnal. She generally bites at night. Therefore, an insecticide- treated bed net can be an extremely effective tool in the prevention of malaria. A mosquito net is hung up over the middle of a bed so that it completely covers one or more sleeping persons. Not only do the mosquito nets create a barrier to mosquitoes, but the insecticide kills mosquitoes on contact as well, creating limited protection even for family members sleeping outside the net. What kind of mosquito nets does the ELCA Malaria Campaign use? ELCA Malaria Campaign partners use long-lasting insecticidal mosquito nets, which retain their insecticidal properties for up to five years or 20 washes. The long-lasting insecticidal mosquito nets contain pyrethroid insecticides and are purchased by our partners, in their own countries, from approved and reliable manufacturers. Mosquito nets treated with a pyrethroid insecticide both repel and kill mosquitoes, offering twice as much protection as untreated nets. Insecticide-treated mosquito nets have proven to be a highly effective method for combating malaria. Do you buy the mosquito nets in bulk and store them at the ELCA churchwide office? No. We encourage the use of sample nets, but those nets are exclusively for educational purposes. The “real” mosquito nets — the ones that are saving lives in Africa — are purchased as locally as possible by our African companions and partners, from a list of approved retailers. Aside from mosquito nets, what are some other ways to prevent malaria? Anopheles mosquitoes breed in areas where water stagnates, so water treatment and sanitation programs are crucial to our efforts.

  • Long-Lasting Insecticidal Nets: Supply Update
    Long-lasting Insecticidal Nets: Supply Update UNICEF Supply Division March 2020 0 Long-lasting Insecticidal Nets - Supply Update March 2020 This update reports on UNICEF’s historical and projected long-lasting insecticidal nets supply, demand, and market developments. UNICEF launched its last tender in 2018, concluding with long- term arrangements for 2019-2020 to ten suppliers with products now listed under the World Health Organization’s prequalification team for vector control. 1. Summary • Long-lasting insecticidal net (LLIN) procurement volumes can vary substantially from year-to-year in accordance with country requirements.1 In general, countries procure new and replacement LLINs for distribution in mass campaigns on a two- to three-year cycle. In 2017 and 2018, UNICEF procured 23 and 13 million nets respectively on behalf of approximately 30 countries, compared to 41.3 million nets in 2016. UNICEF procured 47.4 million nets in 2019 and anticipates procuring an estimated 25 million nets in 2020. • Overall aggregate supply remains stable. UNICEF estimates the total global LLIN production capacity to be 400 million nets annually, against global LLIN deliveries reaching approximately 250 million in 2019, representing over half of the reported requirements. • The weighted average price (WAP) for LLINs secured through UNICEF continues to decline, having decreased by more than 55 per cent over the past eight years from USD 4.20 in 2011 to reach USD 1.88 in 2019, realizing further cost savings for country programmes and partners. • UNICEF concluded its last LLIN tender towards the end of 2018 and issued ten manufacturers long-term arrangements (LTAs) to secure access to LLINs over its 2019-2020 tender period, including to new and innovative products.

In 2010 the World Health Organization (WHO) reported there were 219 million clinical cases of malaria resulting in 660,000 deaths, most of which occurred in Africa. (CDC, 2012c) This parasite has been targeted by the WHO for eradication (Tanner & Savigny, 2008) after decades of focus on management and treatment due to spreading strains of drug-resistant malaria. (Turschner & Efferth, 2009, p. 206) This new battle focuses on preventing malaria infection through educational programs, mosquito nets and insecticide. In addition to these efforts, research is being conducted into the creation of a malaria vaccine.

  • Monitoring Mosquito Net Coverage for Malaria Control in Africa: Possession Vs
    Tropical Medicine and International Health volume 8 no 8 pp 693–703 august 2003 Monitoring mosquito net coverage for malaria control in Africa: possession vs. use by children under 5 years Eline L.

Kabir Cham1, David Alnwick1 and Christopher Dye2 1 World Health Organization, Roll Back Malaria Monitoring and Evaluation, Geneva, Switzerland 2 World Health Organization, StopTB, Tuberculosis Monitoring and Evaluation, Geneva, Switzerland Summary objectives To investigate the strengths and weaknesses of the indicators Ôproportion of households possessing mosquito net(s)Õ and Ôproportion of children under 5 years of age who slept under a net the preceding nightÕ for monitoring malaria control. methods Review of data from household surveys including demographic and health surveys in sub-Saharan African countries. results Net possession ranged among 14 surveyed regions from 0.1% to 28.5% for insecticide- treated nets (ITNs) and among 69 regions from 3.6% to 79.7% for any net. Reported use during the preceding night by children under 5 years of age was between 0% and 16% for ITNs and between 0.7% and 74.5% for any net. On average, in households owning ITN(s), 55% of children slept under it (R2 ¼ 0.97, P < 0.001). For any net, use was )4.2% + 0.875 · possession (R2 ¼ 0.89, P < 0.001); the use of nets, however, also varied somewhat among the surveyed countries (P ¼ 0.003). In-depth surveys suggested that use was lower than possession because: (i) nets were scarce (mean 1.8 per possessing household); (ii) nets were not always used for children and (iii) use was lower during hot, dry months than during cool rainy months, and many surveys had been conducted in the dry season.
