Agriculture and Vector Resistance

Jean Mouchet
1988 International Journal of Tropical Insect Science  
Agricultura1 treatments mainly .against cotton and rice pests put a considerable insecticide pressure on larvae and sometimes adults of several vector species. Resistances to compounds which had never been used for public health, but were currently employed in agriculture were observed among vectors. It was also noticed that resistance level in some vector species was linked to the quantity of the compound used in the same area against crop pests. Resistance in Anopheles gambiae in Africa, in

This is the case of An. dirus and An. minimus in Thailand and An. dnrlingi South America. However several important factors like Anopheles sf@fiens< XèdeFaëjfjj% and Culex-quinquefasciatus, have developed resistance for which agricultural treatments cannot be held responsible. It would be worth saying that the rise in malaria in certain countries, such as India, is only due to the increase of insecticide in agriculture after the "green revolution".
