Preliminary observation on the gradient distribution of hibernating females of Anopheles sinensis and Anopheles pullus in the Republic of Korea.
Hibernating females of the Anopheles hyrcanus complex were collected at 4 different latitudes at the end of the hibernation period in March of 2005 and 2006, and species were confirmed by polymerase chain reaction (PCR) identification. At Paju (37.8 degrees N; average temperature in December February = -3.5 degrees C) 74.6% of the females collected were An. pullus and 22.4% were An. sinensis. At Seosan (36.8 degrees N; December-February average temperature = -1.0 degrees C) and Buan (35.7 degrees N; December-February average temperature = 0.4 degrees C) 14.7% and 14.8% were An. pullus, and 85.3% and 85.2% were An. sinensis, respectively. At Haenam (34.6 degrees N; December-February average temperature = 3.1 degrees C) only An. sinensis was found. Our preliminary results indicate that An. sinensis, unlike An. pullus, is not adapted to survive in cold weather.
