Observations on the fecundity of aedes triseriatus (diptera: culicidae)
1974
JALIL, M.
Laboratory experiments were designed to determine the effects of blood source, blood amount, body size, body weight, mating, and age on the fecundity of Aedes triseriatus (Say). This study indicates that these factors affect the number of eggs laid. More eggs were laid when fed on warm-blooded than on cold-blooded animals. The number of eggs laid showed a positive correlation with the amount of blood ingested from 0.6 mg to 3.0 mg. An amount of 0.6 mg was necessary to initiate ovulation, but amounts in excess of 3.0 mg did not affect fecundity. Body size and weight were also positively correlated with the number of eggs produced. The virgin females laid fewer eggs and the duration of their oviposition period was considerably greater than that of the mated ones. In this study, age also proved to be an important factor in determining fecundity; females older than 15 days laid significantly fewer eggs than younger females.
