A laboratory oviposition study in Aedes albopictus (Diptera: Culcidae) with reference to habitat size, leaf litter and their interactions

抄録

This work presents the results of an experiment on the oviposition of Aedes albopictus (Skuse) where the oviposition sites were different sized-containers with or without leaf from the maple (Acer buergerianum) or from the camphorous (Cinnamomum japonicum). Oviposition responses varied according to container type, to leaf presence/absence as well as leaf type and amount. Oviposition was highest in the "large" container and in the presence of leaves, especially maple leaves, known as good larval nutritional substrate. In nature, container opening surface size is often correlated with the permanence of water as well as leaf litter input; thus, the most likely explanation of our results is that Ae. albopictus can discriminate habitats for oviposition that increase success for its offspring.
