Molecular evidence for the presence of malaria vector species a of the Anopheles annularis complex in Sri Lanka.

ABSTRACT:

Background

Anopheles annularis s.l. is a wide spread malaria vector in South and Southeast Asia, including Sri Lanka. The taxon An. annularis is a complex of two sibling species viz. A and B, that are differentiated by chromosome banding patterns and ribosomal gene sequences in India. Only species A is reported to be a malaria vector in India while the occurrence of sibling species in Sri Lanka has not been documented previously.

Findings

Anopheline larvae were collected at a site in the Jaffna district, which lies within the dry zone of Sri Lanka, and reared in the laboratory. Emerged adults were identified using standard keys. DNA sequences of the D3 domain of 28S ribosomal DNA (rDNA) and the internal transcribed spacer-2 (ITS-2) of the morphologically identified An. annul
