  • Reply to: Smell of infected people attracts more anophelines   1 hour 55 min ago

    Dear Bill,

    Let me provide some more info on this matter. First, African anophelines are sensitive to extremely low concentrations of fatty acids from foot odour - thus, washing will not reduce the number of bites. In fact, these same odours are also produced on other parts of the body...

    The study just published on additional attractiveness of gametocyte carrying hosts is not new and has in fact been done in humans and was published back in 2005 (

    The risk of picking up gametocytes is higher when feeding on children than on adults, so gambiae has developed a tendency to prefer biting adults. The parasite obviously needs a 'taxi', so tries to enhance the attractiveness of gametocyte carriers. It's an evolutionary war...

    But washing of feet is, unfortunately, not going to help us much...

    Is it wise to use pyrethroids for IRS when resistance is appearing? There are other families of insecticides such as organo-phosphates etc.
  • Reply to: Last week at MalariaWorld: History being written in front of our eyes...   6 days 11 hours ago

    Hi editorial folk: I have not seen the MJ article by David Nygren and others (Nygren et al. Malaria Journal 2014, 13:231 reported in the Malaria World list (it came out about 3 weeks ago). It relates to the measurement of dew point in the air through the use of MODIS satellites and the association of this information with incidence of malaria measures in high moderate and low transmission areas, in Southern Zambia. I would like to see what others think about this as it may help defining potential and actual "hot spots" of transmission.

  • Reply to: Planes, trains and vehicles: The neglected role of passive transportation!   1 week 2 days ago

    Dear Jeff
    We definitely see your general point about the value of engineering solutions but we suspect that currently we are still at the stage of trying to determine in what circumstances passive transportation is of practical importance. Only then will we be in a position to determine where and when might warrant resources devoted to preventing it.
    While, whatever effective approaches that are resource efficient should be part of control programs, with respects to sterile insects technique (SIT) it might be notable that the most spectacular achievement of this approach, the eradication of screwworm from North and Central America, occurred through a fairly singular application of SIT (though other might know more about this). We anticipate for the SIT program in Sudan that considering impact of passive transportation in its final stages might has good prospects to sustain the control efforts of An. arabiensis in the region.
    We will definitely consider doing our next Colum on ‘structures’ to fulfil your hat-trick of ‚’ Structures, Transportation, and Water & Air Resources’.-is there a prize?
