This GCE project set out to develop a novel way of controlling malaria-transmitting mosquitoes by deploying live, insect-eating plants around houses and in mosquito breeding sites. Field surveys were undertaken to collect and identify carnivorous plants. Aldrovanda vesiculosa and Utricularia reflexa were collected from swamps in various locations in Uganda and brought to the laboratory where they were kept in distilled water into which larvae of Anopeheles gambiae were introduced and the impact of the plants studied.

If this is effective for mosquito control, where could I purchase/propagate or reasonably obtain these plants? Also, has anyone any info on growing Artemisinin plants for mosquito abatement? Please advise. Thanks, Rich

Dear Jaaper, first hand view of your idea is good it may reduce the need for insecticides, but we should not forget that we have been killing the mosquitoes by spraying insecticides with only limited success. We should remember that we cannot create a vaccuum in the ecosystem, if there is food there will be someone to consume it, and this is always by the most suitable (well adapted) species which in this case is mosquito owing to its great fertility, every time you kill it, everytime it gets replenished. Henc, if we really want to eliminate malaria by vector elimination, we have to render the eggs nonviable so that it gets replaced by the second best adapted species. Please see the link below for the same

Thanks Sanjey. Our idea is to approach mosquito control by using as many approaches as possible and find complementary methods. This way we hope to reduce over use of any one method. Remember that no one approach will be suitable for all areas. Thanks for your comments.
