Keywords:
Dengue and Dengue Homorrhagic Fever, Aedes mosqutoesAbstract
This study aimed to determine dengue virus infection rates in Aedes mosquitoes from Nakhon sri Thammarat and Phetchabun Province. Aedes aegypti and Ae. albopictus were caught from the patient's houses, neighbor's houses which located in the radius 100 meters from patient's houses and houses in village without patients.. Aedes mosquitoes were collected in rainy season and summer during June 2004 to May, 2005. Dengue virus in mosquitoes was detected by RT-PCR. The results revealed that total 3,459 mosquitoes were collected ( 1,897 of Ae. aegypti and 1,562 of Ae. albopictus). The 1,885 Aedes mosquitoes were caught from Nakhon sri Thammarat, composed of 464 Ae. aegypti and 1,421 Ae. Albopictus. In the rainy season, Ae. Albopictus was more prominent than Ae. aegypti approximately 3 times. The 0.92% of Ae. aegypti was infected by DENV-1 while Ae. albopictus was infected by DENV-1 (0.40%) and DENV-3 (0.12%).The 1,574 of Aedes mosquitoes were isolated as 1,433 of Ae. aegypti and 141 of Ae. Albopictus from Phetchabun Province. The population of both species is increasing in the rainy season which Ae. Aegypti more than Ae. albopictus approximately 10 times. Dengue infection rates in Ae. aegypti was 1.76% identified as DENV-1(0.14%) and DENV-4 (1.62%).
