OBJECTIVE: To compare the difference of resting habitat between Anopheles minimus A and An. minimus C in Yunnan Province.
METHODS: A village was selected in Mengla and Yuanjiang County respectively to collect mosquitoes by hanging ultraviolet lamps inside the cattle pen and human dwellings. The samples were identified by multiplex-PCR after morphological examination. Suspicious An. minimus A/C hybrid samples were identified by PCR-ASA, PCR-RFLP and D3 region sequence.
RESULTS: In human dwellings, the proportion of An. minimus A and C was 21.35% and 78.65%, and in cattle pen, 28.54% and 71.46% respectively. As for the An. minimus A/C hybrid, the result of PCR-ASA and PCR-RFLP displayed the pattern of both An. minimus A and An. minimus C (PCR-ASA: 376, 294 and 112 bp, PCR-RFLP:108, 268 and 376 bp), the D3 sequence displayed heterozygosis in the variation place of An. minimus A and An. minimus C, which means that the hybrid possesses the signal of both An. minimus A and An. minimus C.
CONCLUSION: There is no resting habit difference between An. minimus A and An. minimus C in Yunnan Province. In Mengla County, 5 An. minimus A/C hybrids have been found for the first time.
