To generate life table characteristics for the dengue vector Aedes albopictus (A. albopictus) under uncontrolled conditions, incorporating both the aquatic and the adult stages.
Ten females derived from wild pupae were allowed to fully blood-feed on restrained mice. 774 eggs were hatched in seasoned water. F1 larvae were followed for development until their F2 counterparts emerged as adults. Some population parameters were monitored (F1) or estimated (F2).
A. albopictus exhibited increased fecundity and egg hatch success. Immature development was quick. Immature survival was high, with lowest rate in the pupal stage. Adult emergence was about 81% and sex ratio was close to 1:1. Generational mortality (K) was about 28%. A high proportion of females completed a reproductive cycle and the obtained parity rate was predicted to lead to higher fecundity in the next generation.
It can be concluded that natural A. albopictus populations in Penang seem largely determined by quick development in combination with low immature loss and increased oviposition.
在不受控制的条件下,结合水生和成虫阶段,生成登革热媒介白纹伊蚊的生命表特征。
让10只源自野生蛹的雌性白纹伊蚊在受限小鼠身上充分吸血。774枚卵在陈水中孵化。对F1代幼虫进行发育跟踪,直至其F2代成虫出现。监测了一些种群参数(F1代)或进行了估计(F2代)。
白纹伊蚊表现出繁殖力增强和卵孵化成功率提高。未成熟发育迅速。未成熟阶段存活率高,蛹期的存活率最低。成虫羽化率约为81%,性别比接近1:1。世代死亡率(K)约为28%。很大比例的雌性完成了一个生殖周期,预计所获得的经产率会导致下一代繁殖力提高。
可以得出结论,槟城的自然白纹伊蚊种群似乎很大程度上由快速发育、低未成熟阶段损失和产卵增加共同决定。
