【 摘 要 】

The object of this work was to determine of gonotrophic diel pattern of female Aedes aegypti in laboratory and field conditions. Three day-old female mosquitoes were the fed on chicken blood and transferred to bioassay cages. Four oviposition substrates were offered: paper sulfite, filter, butter and towel. The results showed that filter paper received a significantly higher (40.4%) percentage of deposited eggs than the other oviposition substrates. After their first blood meal, females started to oviposit on the 3rd model day; 35.7% of the total number of eggs deposited. The oviposition diel patterns of females were observed every two hours during the photoperiod in the laboratory and in the field. In the laboratory, the periodicity of oviposition showed that the highest egg deposition occurred during the 9th- 12thh of photophase and 1st - 2ndh of scotophase. In the field, the highest egg deposition occurred during the 9th - 12thh of photophase and 1st - 4thh of scotophase. These results point out that Aedes aegypti showed an oviposition periodicity pattern that can subsidize monitoring and or control of vector insect. itis suggested that ovitraps should be placed in the field during the morning hours since the captures occur during afternoon.
