A 24 h cycle of biting activity of Armegires subalbatus. Biting activity of a given population of Ar. subalbatus represents mean relative human landing rate (HLR) (± 1 standard error denoted as bar) for each hour of mosquito collection by using 3 geographically defined population samples of each ecotype that were obtained from 3 different plantation areas connecting to forest fringes in Suratthani, Trat, and Rayong provinces. Relative HLR infers the number of human blood-seeking Ar. subalbatus female adult mosquitoes per night per person at each hour of mosquito collection (or HLR), which is divided by a sum of HLR for 24-h mosquito collection for each ecotype. Both forest and plantation ecotypes of Ar. subalbatus tend to seek human blood meals with a major peak hour (1800–1900 h) and another minor peak hour (0600–0700 h).
