[Morphology and habits of An. anthropophagus and its role in malaria transmission in Hengqin Island of Zhuhai City].
OBJECTIVE
To study the morphology and ecological habits of An. anthropophagus and its role in malaria transmission in Hengqin Island of Zhuhai City, Guangdong Province.


METHODS
Mosquitoes were captured through overnight/semi-overnight trapping with human and cattle baits as well as lamp-trapping. The specimens were morphologically identified through describing the adult mosquitoes, eggs and pupae. The relevant parameters were collected to calculate the vectorial capacity of both An. anthropophagus and An. sinensis.


RESULTS
There is no morphological difference between the isolate of An. aothropophagus from Hengqin Island and that from Jiangsu Province. Its human blood preference ratio and human blood index was 0.94 and 0.75 respectively, and the vectorial capacity of An. anthropophagus was 7.36 times higher than that of An.sinensis (5.1914/0.7052).


CONCLUSIONS
The isolate of An. anthropophagus from Hengqin Island belongs same species to that from the mainland, which prefers to human blood and shows higher malaria transmission potential.
