Plant material forms the nutritive base for many aquatic systems, including treehole and container environments important in the production of mosquitoes. However, examination of the importance of plant leaf species on these systems has been rare in the literature. Previous work in lotic systems has suggested that plant diversity effects may or may not be additive in terms of decay rate and insect biomass production. To determine the effects of plant species on mosquito larval growth and survival, we conducted a series of experiments examining how leaves of four palnt species(Vitis aestivalis (Vitaceae), Quercus virginiana (Fagaceae), Psychotria nervosa (Rubiaceae), and Nephrolepsis exalta (Nephrolepidaceae)) affect two species of mosquitoes (Ochlerotatus triseriatus and Aedes albopictus). We examined the effects of each species of plant on larval survival, growth, and finite rate of increase and, for Aedes albopictus, the effects of every combination of the four plant species. In addition, we investigated the oviposition response of each mosquito species to leaf infusions of two of the four species (Quercus virginiana and Vitus aestivalis). We found that larval growth differed significantly among species of plant litter, and combinations of plant material had roughly additive effects on Aedes albopictus. We also found significant differences in oviposition responses to leaf infusions between the two mosquito species.
