Resting Behaviour of Zika and Dengue Vector Aedes Aegypti Mosquito in Gia Lai, Viet Nam
Keywords:
Mosquitoes, Aedes aegypti, animal behaviourAbstract
The study was conducted in Pleiku city and Dak Po district belonging to Gia Lai province during the period 2016-2018. The results showed that Aedes aegypti was found in all study sites. The distincly anthropophilic and endophilic behaviours of Aedes aegypti make it a very effective vector of Dengue, Chikungunya, and Zika viruses. In total, 95.3% of 746 resting adult Ae. aegypti were collected indoors, and only 4.7% outdoors. Indoor primary resting locations (73.8%) included living rooms (13.9%), bathrooms (4.8%), and others (7.5%). In Pleiku city, most of Ae. aegypti adults were collected on nets/ curtains (164 mosquitoes, 53.2%), followed by clothes (30.2%) and the lowest on wall surfaces (0.3%). Similarly, in Dak Po district, total of 422 specimens were collected and the highest collection was on clothes surfaces (234 mosquitoes, 53.4%), followed by nets/ curtains (176 mosquitoes, 40.2%) and the lowest on television surfaces (0.7%). In all sites, Ae. aegypti significantly rested from 1-2 m of height (72.3%).
