    Bart, that is really good to hear! Congratulations for trying to outwit the pesky buzzing critters.
    Incidentally, although they don't give precise figures, if one studies the latest financial reports from the US PMI, it is quite likely that indoor spray costs have tripled recently and are now close to $18 per person protected per year.
    These huge cost increases might be due partly to the switch to bendiocarb.
    This gives even more reason to support your approach.

    Nice views, and for anyone with a little background in evolutionary biology common sense. The problem with the current policy to deal with resistance is that resistance management is advocated but hard to implement let alone be defined in terms of what it should deliver. Resistance breaking is easier to grasp - it is a tool, method, or active that can kill resistant mosquitoes.

    In the Kilombero Valley of Tanzania we have now completed 1559 houses: full window screening, door improvement, closing of the eaves, and installation of eave tubes (with actives). Results are as expected: the indoor density of anophelines is reduced by 85-90% for both gambiae sl and funestus.

    Eave tubes are ideal in the sense that they offer management options since you can put more than 1 active on (the tubes are installed at eave height and therefore out of reach of house occupants).

    Compared to the cost of IRS, eave tubes are highly competitive and use 98% less insecticide.

    Coarse application of insecticides (spraying the whole house) may not be necessary if we use the behavioural ecology of the target insect cleverly (i.e. they prefer to enter the house through the eaves). Cheaper, equally effective, greener.

    several studies have shown that microbial infections arouse the mosquito imunosystem and thus lead to an increased encapsulation (melanization) of the oocysts. However, some studies have shown that melanization is more commonly oberved in laboraory strains of mosquitoes than in naitive mosquitoes of the same species. So, it is a grey field. It would be nice if the authors could also test Metharhizium in their model Ole Skovmand Intelligent Insect Control
