Exploiting Sugar Feeding Behaviors For Mosquito Control
… but relatively little is known about phytophagy. Sugar feeding is an essential aspect of mosquito biology. Both male and female mosquitoes must consume sugar as a primary fuel source. Mosquitoes use olfactory and visual cues among other cues to find suitable food sources. Abiotic factors, such as …

Factors Influencing Sugar Feeding in Invasive Mosquitoes
Phytophagy (i.e., feeding on plant-derived materials) is an essential component of mosquito biology. Yet, it has been historically neglected as most research effort has been concentrated on host-seeking behavior and pathogen transmission. As mosquitoes are the deadliest animals on earth and because …

An investigation of sugar feeding by black flies (Diptera: Simuliidae)
… Simuliidae), the same cannot be said for sugarmeals. Both sexes feed on sugar which provides energy for flight and it has been commonly held that nectar is the major carbohydrate source. This thesis addresses the question of whether a non-floral carbohydrate source, specifically homopteran …

The Plant Diet of Mosquitoes: Sugar Feeding on Ornamentals and Wildflowers
… the mosquito's biological need to feed on sugar. However, an improved understanding of sugar feeding behavior is needed to better optimize these strategies. Here, we determined the prevalence of mosquito sugar feeding on ornamental plants and wildflowers by using DNA barcoding on mosquitoes …

Discerning Patterns of Floral Sugar-Feeding: Dynamics of the Mosquito Culex antillummagnorum in Puerto Rico
<p>Mosquitoes rely on sugar feeding for survival, primarily from flowering plants, yet mosquito–plant interactions remain understudied. I examined plant-feeding associations of the mosquito <em>Culex antillummagnorum</em> in the Luquillo Experimental Forest of Puerto Rico, which may clarify …

Effects of habitat and plant volatiles on mosquito spatial, seasonal, and chemical ecology
… of ecological factors on mosquito prevalence, sugar-feeding, and host seeking is relatively unknown. In an attempt to address this knowledge gap, we first investigate how several ecological factors (i.e., temporal, seasonal, and topographical) affect mosquito sugar feeding and population …

Food foraging in adult parasitoid Cotesia rubecula : how sugar sources contribute to survival and reproduction / by Gitta Siekmann.
Examines sugar foraging in the field by adult female parasitoid wasp, Cotesia rubecula (Hymenoptera, Braconidae), to determine its effect on fecundity and lifespan. In the field, the area in which wasps search for sugar is likely to depend on the degree of association of hosts with nectar or …

Effects of Fluid Properties on the Dynamics of Mosquitoes' Ingestion Pumps
This thesis explores the feeding structures of insects, which have evolved over millennia to utilize a variety of dietary sources. It examines the mouthparts of insects feeding on plants, other bugs, or vertebrate blood, analyzing how these structures influence or limit their diet. Focusing …

Influence of dietary nutrients on life history-related traits of black flies and mosquitoes
The sugar-feeding ecology of dipteran vectors has recently been targeted because it presents opportunities to inoculate common food sources for these dipterans with entomopathogenic bacteria as a means of controlling the population of host-seeking adult dipteran vectors. Whereas this approach to …

Immunity Against Malaria: an Atlas of the Mosquito Cellular Immune System at Single Cell Resolution
… Anopheles hemocytes 1,3 and 7 days after sugar-feeding, blood-feeding, or infection with Plasmodium berghei, as well as 3123 A. aegypti hemocytes. We identified 9 cell sub-types, including novel effector, phagocytic, and anti-microbial cell subtypes, in addition to dividing progenitor …

The Neuropeptide Regulation of Host-Seeking Behavior in Aedes Aegypti Mosquitoes
… that multiple NPYLR1 agonists, including the feeding-related Short-Neuropeptide-3 (sNPF3), are capable of inhibiting host-seeking behavior when injected into non-blood-fed females. To investigate whether NPYLR1 is required for Head Peptide-I inhibition, we pioneered targeted mutagenesis with …

Evaluation of the role of plant-derived chemicals in mosquito ecology and control
Although blood-feeding behavior in female mosquitoes, required both for reproduction and transmission of disease pathogens, has been extensively studied, plant-feeding is an essential element in the life histories of most mosquito species. For these species, adults of both sexes seek out and depend …

Direct and indirect effects of native and invasive plants on mosquito ecology
… influencing microclimate conditions, supplying sugar-feeding sources, and altering communities of wildlife blood-meal hosts. This dissertation examines direct and indirect effects of understory shrubs, including species both native and invasive to North America, on the ecology of Culex pipiens, …
