POPULATION ECOLOGY Influence of Leaf Detritus Type on Production and Longevity of Container-Breeding Mosquitoes

چکیده
Freshwater ecosystems are positioned at low levels in the landscape and receive large inputs of diverse plant-based detritus, a major source of energy for consumers in aquatic ecosystems. We conducted Þeld experiments in Urbana, IL to determine the independent and combined effects of leaves of common tree species including thenorthern redoak (Quercus rubraL.), sugarmaple (Acer saccharumMarshall), andcommonhackberry (Celtis occidentalisL.)on theperformanceof containerdwelling mosquitoes, especially Culex restuans Theobald (Diptera: Culicidae). We tested the hypothesis that leaf species have asymmetric effects on adult mosquito production and longevity. Hackberry followed by combined leaf treatments andmaple produced the greatest number of pupae, whereas oak leaves produced the fewest. Leaf treatments had no signiÞcant effects on adult female sizes but female longevity was signiÞcantly lower in oak leaf treatments compared with the other leaf treatments.TheseÞndings support thehypothesis that leaf species identity inßuences theperformance of container-dwelling mosquitoes with potential consequences for the transmission of infectious diseases.

Influence of leaf detritus type on production and longevity of container-breeding mosquitoes.
Freshwater ecosystems are positioned at low levels in the landscape and receive large inputs of diverse plant-based detritus, a major source of energy for consumers in aquatic ecosystems. We conducted field experiments in Urbana, IL to determine the independent and combined effects of leaves of common tree species including the northern red oak (Quercus rubra L.), sugar maple (Acer saccharum M...
متن کاملInterspecific and intraspecific differences in foraging preferences of container-dwelling mosquitoes.
Feeding preferences of larval container-dwelling mosquitoes are not well understood. Primary production is often absent in container systems and external inputs of animal and plant detritus supply the energy base of container food webs by supporting microorganism prey for mosquitoes. We quantified the feeding preferences of Aedes albopictus (Skuse), a non-native invasive mosquito, and Ochlerota...
متن کاملLarval feeding behavior of three co-occurring species of container mosquitoes.
Interspecific differences in foraging behavior may help to determine whether the outcome of interspecific competition is coexistence or exclusion. Mosquitoes in the genus Culex are commonly described as foraging primarily by filtering the water column. This behavior contrasts with that of other container-dwelling genera, such as Aedes and Ochlerotatus, that are thought to forage primarily by br...
متن کاملHow Diverse Detrital Environments Influence Nutrient Stoichiometry between Males and Females of the Co-Occurring Container Mosquitoes Aedes albopictus, Ae. aegypti, and Culex quinquefasciatus.
Allocation patterns of carbon and nitrogen in animals are influenced by food quality and quantity, as well as by inherent metabolic and physiological constraints within organisms. Whole body stoichiometry also may vary between the sexes who differ in development rates and reproductive allocation patterns. In aquatic containers, such as tree holes and tires, detrital inputs, which vary in amount...
متن کاملEffects of combination of leaf resources on competition in container mosquito larvae.
Resource diversity is critical to fitness in many insect species, and may determine the coexistence of competitive species and the function of ecosystems. Plant material provides the nutritional base for numerous aquatic systems, yet the consequences of diversity of plant material have not been studied in aquatic container systems important for the production of mosquitoes. To address how diver...
