Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p>Overwintering mosquitoes in a grassy field were surveyed at 13 different localities from December 2007 to February 2008 in the Republic of Korea (ROK). Mosquitoes were collected by putting a white colored tent on the grass, without the base, and heating the inside of the tent. A total of 784 female adults comprising seven species were collected during the study period, including 395 (45.6%) <italic>Anopheles pullus</italic>, 338 (43.2%) <italic>An. sinensis</italic>, 21 (2.7%) <italic>An. belenrae</italic>, 2 (0.3%) <italic>An. kleini</italic>, 43 (5.5%) <italic>Culex tritaeniorhynchus</italic>, 20 (2.5%) <italic>Cx. inatomii</italic>, and 1 (0.3%) <italic>Cx. pipiens</italic> complex. The mosquitoes showed different overwintering distributions by temperature zone and locality. Predominant species, the malaria vectors <italic>An. pullus</italic> and <italic>An. sinensis</italic>, showed different overwintering distributions. <italic>Anopheles pullus</italic> had a 90.9% collection rate except for Youngju and an average – 0.6°C temperature between December and February. <italic>Anopheles pullus</italic> showed >50% collection rate in most regions maintained below an average of −1.4°C, and the rate of <italic>An. sinensis</italic> showed more than 50% collection rate in all regions maintained at an average above −1.1°C. Other species showed regional characteristics; <italic>An. belenrae</italic> was distributed in the northwest part of the ROK, and <italic>An. kleini</italic> was collected rarely at one locality in the middle part of ROK. <italic>Culex tritaeniorhynchus</italic>, a Japanese encephalitis virus vector, was distributed in the southern and costal region and maintained at an above average of −1.0°C. <italic>Culex inatomii</italic> was collected on the coastal region of the ROK.</p> </abstract>
