Molecular forms of the Indian Anopheles subpictus complex differ in their susceptibility to insecticides and the presence of knockdown resistance (kdr) mutations in the voltage-gated sodium channel.

Objectives: To investigate the differential insecticide-susceptibility of two molecular forms of Anopheles subpictus complex (A and B) against DDT and pyrethroids, the occurrence of knockdown resistance (kdr) mutations in these forms, and the association of kdr mutations with insecticide resistance.

Methods: Insecticide susceptibility tests of An. subpictus s.

Molecular forms of Anopheles subpictus and Anopheles sundaicus in the Indian subcontinent.

Background: Anopheles subpictus and Anopheles sundaicus are closely related species, each comprising several sibling species. Ambiguities exist in the classification of these two nominal species and the specific status of members of these species complexes. Identifying fixed molecular forms and mapping their spatial distribution will help in resolving the taxonomic ambiguities and understanding their relative epidemiological significance.
