Ribosomal DNA-probes differentiate five cryptic species in the Anopheles gambiae complex.

This study describes the use of ribosomal DNA probes to identify the species of individual mosquitoes in the Anopheles gambiae complex, a group of six morphologically identical mosquito species among which are two of the principal vectors of malaria in Africa. The DNA probes are sequences of DNA derived from the ribosomal genes of An. gambiae. Each probe reveals a different sized restriction enzyme fragment specific to each of the five species in the complex that were examined in this study: An. gambiae, An. arabiensis, An. quadriannulatus, An. melas and An. merus. The probes detect highly repeated sequences of DNA, thus the method is sufficiently sensitive to be applied to a small portion of a mosquito. Furthermore, because the DNA can be extracted from desiccated or alcohol preserved specimens, the test is compatible with other mosquito assays performed on dried specimens such as blood meal and malaria sporozoite antigen ELISAs. Determination of the nucleotide sequences that underlie the species-specific restriction enzyme site differences detected by these probes will lead to the development of synthetic DNA probes that can be used to identify an individual mosquito to species on the basis of a simple dot-blot or squash-blot.
