The effects of simulated rainfall on immature population dynamics of Aedes albopictus and female oviposition
Larvae of Aedes albopictus Skuse typically inhabit natural and artificial containers. Since these larval habitats are replenished by rainfall, Ae. albopictus may experience increased loss of immature stages in areas with high levels of rainfall. In this study, we investigated the effects of rain...

Summary: | Larvae of Aedes albopictus Skuse typically inhabit natural and artificial containers. Since these larval
habitats are replenished by rainfall, Ae. albopictus may
experience increased loss of immature stages in areas with
high levels of rainfall. In this study, we investigated the
effects of rainfall and container water level on habitat
quality, population density, and oviposition activity of Ae.
albopictus. In field and laboratory experiments, we found
that rainfall resulted in the flushing of breeding habitats.
Excess rain negatively impacted larval and pupal retention,
especially in small habitats. When filled with water to
overflowing, container habitats were significantly repellent
to ovipositing females. Taken together, these data suggest
that rainfall triggers population loss of Ae. albopictus and
related species through a direct detrimental effect (flushing
out) and an indirect effect (habitat unsuitability and
ovipositional repellency |
