Abstract Details

2012, Master of Public Health, Ohio State University, Public Health.
A nine-week field work was conducted during summer 2010 (July 19 to September 17) to better understand the distribution of the eastern tree-hole mosquito, Aedes triseriatus, with emphasis on the potential environmental factors that may have impacts on its breeding and egg-laying behaviors. Five neighborhoods of Franklin County, Ohio were chosen and ten oviposition traps were set at each location. To examine mosquito preference to habitats, two different elevations and six substrate types were selected and included into the weekly egg surveys. Eggs were then hatched and reared into emergence in the mosquito control facility, followed by identification to species. Weekly total number of eggs among all five locations showed the highest count (6561) in mid August (week 5). Egg counts for Gahanna and Green Lawn Cemetery peaked (471 and 3169, respectively) in week 5 as well. Egg counts for Obetz Memorial Park peaked (2981) a week earlier, while those for Prairie and Hilliard Municipal Park peaked (1764 and 298, respectively) one or two weeks later. Green Lawn and Obetz had significantly more eggs deposited than the others (p= 0.004). No significant difference in mean egg counts among ovitrap sites (of the same location) was observed; however, ovitraps placed at ground level (rather than those at elevation) in Hilliard received significantly more eggs (p=0.004). Seasonal factors such as temperature and other environmental factors in response to the seasonal effects were suggested from the observed variations of egg counts over the nine weeks. Only Green Lawn and Obetz showed positive relationship between temperature and egg-laying. Substrates with darker color showed more egg deposition though not statistically supported. Total 793 Aedes triseriatus and 1480 Aedes albopictus were identified and positive associations in abundance of these two species were observed mostly. Evidence accumulated provides insights to the site selection for local mosquito surveillance and control.
