Breadfruit has been coined the new ‘super-fruit’ and according to some has the ability to alleviate world hunger. However, it has recently been discovered that breadfruit may also have a very different role in saving lives. Scientists have isolated three chemicals produced in the male inflorescence of the breadfruit that are extremely effective at repelling flying insects, the most significant of which are mosquitoes.

Progress in malaria control in the past decade can be attributed largely to a massive increase in the number of insecticide based management programmes targeting malaria carrying mosquitoes, using methods that include indoor residual spraying and insecticide impregnated bed nets. The effectiveness of these management techniques is now being compromised by insecticide resistant mosquito populations. In 2012, the UN World Health Organisation (WHO) launched a strategic plan to help fight insecticide resistance in malaria vectors. A crucial part in the management of insecticide resistant mosquito populations is access to current information on insecticide resistant populations.  IR Mapper is a new interactive online mapping tool used to track insecticide resistance in mosquitoes. The tool collaborates reports of insecticide resistance in malaria vector mosquitoes into maps which aim to assist vector control strategies. Data consolidation for the programme was conducted by Swiss company Vestergaard Frandsen, the Kenyan Medical Research Institute (KEMRI) and the US Centers for Disease Control and Prevention (CDC).   To make this information available to users, an interactive map of all publicly available insecticide resistance data has been developed, with an interface developed by ESRI Eastern Africa
