Title: | STUDIES ON SOME OVIPCSITIONAL PREFERENCES OF AEDES AEGYPTL (DIPTERA : CULICIDAE) | Authors: | WINNIE HO | Issue Date: | Dec-1985 | Citation: | WINNIE HO (1985-12). STUDIES ON SOME OVIPCSITIONAL PREFERENCES OF AEDES AEGYPTL (DIPTERA : CULICIDAE). ScholarBank@NUS Repository. | Abstract: | The components of the autocidal ovitrap were varied so that the parameters favourable to the oviposition of Ae. aegypti could be determined and employed to enhance the attractiveness of the device. The oviposition pattern of the female was found to be influenced by nutrition, temperature and r elative humidity. Under the existing experimental conditions, most eggs were l aid on the third day after bloodmeal. The attractiveness of standing tap water was observed under two instances, when different concentrations of hay infusion was offered; and the other, when medium containing larval food was used. Although paddles dyed blue elicited most response from the females, the undyed ones was in no way less preferred. While a rough surface proved to be attractive, the different arrangements of the paddles was of no influence. Apparently, Ae. aegypti utilised visual cues ,(such as colour and reflectivity of water), humidity, odour, texture and chemical nature of the oviposition site for location and oviposition. | URI: | https://scholarbank.nus.edu.sg/handle/10635/149052 |
