“…Similar impacts of plant diets on mosquito fecundity have been observed for An. gambiae [30,35] and Culex pipiens [33]. Although sugar feeding has long been suggested to impact fecundity of Aedes mosquitoes [36,37], to the best of our knowledge, this is the rst evidence directly linking plant feeding to Ae.…”

“…The study by Olson et al [17] demonstrated that sugar feeding occurs at a much higher frequency than previously reported, with collection method and season being important in in uencing the proportion of fructose-positive females captured. Plant sugars, particularly fructose, have been shown to provide a ready source of energy for various metabolic processes in several mosquito species [17,[30][31][32][33]. Extended survival time is pivotal in the transmission of vector-borne diseases as it guarantees completion of extrinsic incubation of the causative agents and increases the chances of multiple infective vertebrate host bites [34].…”

Background In a recent study using DNA barcoding, we identified the plants fed upon by four Afro-tropical mosquito species that vector dengue, malaria, and Rift Valley fever. Herein, we have expanded on this study by investigating the role of three of the plants Pithecellobium dulce (Fabaceae), Leonotis nepetifolia (Lamiaceae), and Opuntia ficus-indica (Cactaceae) on survival, fecundity, and egg viability of the dengue vector Aedes aegypti. Methods We tested these effects using females that received a) an initial three rations of bloodmeal, and b) received no bloodmeal at all. Two controls were included; age-matched females fed on glucose solution with or without initial bloodmeal, and those fed exclusively on bloodmeal. Data was collected daily over a 30-day period. The amino acid content of Ae. aegypti guts and the amino acid content of their respective diets was detected by coupled liquid chromatography – mass spectrometry. Results Females fed on P. dulce and exclusive bloodmeal had a shorter survival than those fed on glucose. On the other hand, females fed on L. nepetifolia survived longer than those fed exclusively on bloodmeal, whereas those fed on O. ficus-indica had the shortest survival time. With initial bloodmeal, females fed on L. nepetifolia laid 1.6-fold more eggs while those fed on the other diets laid fewer eggs, compared to those fed exclusively on bloodmeal. Hatching rates of the eggs laid varied with the diet. Mass spectroscopic analysis of gut contents of mosquitoes exposed to the different diets showed qualitative and quantitative differences in their amino acid levels. Conclusion Our findings highlight the central role of plant nutrients in the reproductive fitness of dengue vectors which may impact their disease transmission potential.

“…Mosquito is able to differentiate different plant species and prefers to feeding on those benefiting itself most (Gouagna et al, 2014;Manda et al, 2007a;Manda et al, 2007b). Feeding on the preferred plants increases mosquito's life span and improves its fecundity (Manda et al, 2007a;Stone et al, 2012;Yu et al, 2016). The sugars from different plant species also influence the capability of Anopheles to transmit malaria parasite (Ebrahimi et al, 2018;Gu et al, 2011;Hien and Dabire, 2016) .…”

Dietary sugar is the major energy source for mosquitoes, but its influence on mosquitoes' capability to transmit malaria parasite remains unclear. Here we show that Plasmodium berghei infection changes global metabolism of Anopheles stephensi with the most significant impact on glucose metabolism. Supplementation of glucose or trehalose (the main hemolymph sugar) to mosquito increases Plasmodium infection by alkalizing the mosquito midgut. The glucose/trehalose diets promote rapid growth of a commensal bacterium, Asaia bogorensis, which remodels glucose metabolism and consequently increases midgut pH. The pH increase in turn promotes Plasmodium gametogenesis. We also demonstrate the sugar composition from different natural plants influences A. bogorensis growth and Plasmodium infection is associated with their capability to expand A. bogorensis. Altogether, our results demonstrate that dietary glucose is an important factor that determines mosquito's competency to transmit Plasmodium and further highlight a key role for mosquito-microbiota metabolic interactions in regulating development of malaria parasite.

“…albopictus survivorship as affected by treatments was subjected to a 1-way ANOVA on transformed (log 10 ) data. Survival time indices were calculated relative to the positive control (i.e., 10% sucrose solution) as follows: Survival Index = (positive control -treatment) / positive control (Manda et al 2007;Yu et al 2016). The Kaplan-Meier test, including a log rank test, was used to compare survival curves and test whether mean survival rate differed between different treatments or between sexes.…”

“…Adult mosquitoes were maintained in 30 × 30 × 30 cm meshcovered cages and provided a 10% sucrose solution ad libitum. Twice daily, larvae were fed a diet of commercial rat food mixed with wheat flour, wheat bran, corn powder, soybean powder, fish meat powder, yeast, salt, and vitamins at a rate of 0.5 g per 100 larvae (Yu et al 2016). Pupae were collected daily and transferred to water-filled cups in mesh-covered cages for adult emergence.…”
