Study of Ceratopogonidae of Medical Importance in Thailand.
Abstract
The operation of light traps in ten provinces of Thailand during a nine to twelve month - period yielded different species of ceratopogonids. In northern provinces; Chiang Mai, Chiang Rai and Phrae where the average rainfall is 1290 mm. Here collecting sites are near villages surrounded by rice fields and inhibitants are crowded in each village. There tend to be more blood sucking species here than in other parts of the country. The number of Culicoides species collected in Chiang Mai, Chiang Rai and Phrae were 22, 19 and 17 respectively with greater numbers of Culicoides homotomus, gemellus, recurvus and subgenus Trithecoides than other species. Culicoides homotomus should be noted here for its specific habitat, as they only occur in this region. In Chiang Rai and Phrae, the populations of Culicoides are highest during November and much lower during December when the cold season has begun.
