Malaria
9
The Malaria triad
10
- Good drugs exist, but pathogens are increasingly resistant. -Most drugs are too expensive: a typical disease of poverty. -No vaccine available. -Chemotherapy works well for individual patient but not for area-wide control. The Malaria problem
11
With the exception of the yellow fever, for which an effective vaccine exists, vector-borne diseases have only been controlled through the control of their arthropod vectors (insecticides, physical protection, environmental management). Examples range from Malaria (Anopheline mosquitoes - e.g. Europe, Latin America, etc.), to American trypanosomiasis (Chagas’ disease - kissing bugs), to Onchocerciasis (River blindness - simulid flies), to…
14
The historic solution: DDT (and other insecticides)
15
Spread of Insecticide Resistance
16
Insecticide Resistance Insecticide Resistance is a heritable change in the sensitivity of a pest population that is reflected in the repeated failure of a product to achieve the expected level of control when used according to the label recommendation for that pest species. Insecticide resistance is a population phenotype, it is the result of natural selection!
17
Insecticide Resistance: management (Develop new insecticides with a different mode of action). (Develop new insecticides with a different mode of action). Use more than one insecticides with a different mode of action (alternating, combinatorial, chessboard).
