“…The effect of a restricted diet in mosquito larva is a rather speculative issue. Previous studies reported that dietary restrictions can lead to longer development rates (Olivo et al, 1979; Tun-Lin et al, 2000; Arrivillaga and Barrera, 2004; Couret et al, 2014; Levi et al, 2014; Aznar et al, 2018), with larvae extending time to achieve the pupal stage (Chambers and Klowden, 1990; Telang et al, 2007; Foster et al, 2012; Banerjee et al, 2015). Some individuals with slower growth rates try to counterbalance this deficit through compensatory growth (Wilson and Osbourn, 1960).…”

Background Mosquito larvae feed on organic detritus from the environment, particularly microorganisms comprising bacteria, protozoa, and algae as well as crustaceans, plant debris, and insect exuviae. Little attention has been paid to nutritional studies in Aedes aegypti larvae. Objectives We investigated the effects of yeast, bacteria and microalgae diets on larval development, pupation time, adult size, emergence, survivorship, lifespan, and wing morphology. Materials and Methods Microorganisms (or Tetramin ® as control) were offered as the only source of food to recently hatched first instar larvae and their development was followed until the adult stage. Protein, carbohydrate, glycogen, and lipid were analyzed in single larvae to correlate energetic reserve accumulation by larva with the developmental rates and nutritional content observed. FITC-labeled microorganisms were offered to fourth instar larvae, and its ingestion was recorded by fluorescence microscopy and quantitation. Results and Discussion Immature stages developed in all diets, however, larvae fed with bacteria and microalgae showed a severe delay in development rates, pupation time, adult emergence and low survivorship. Adult males emerged earlier as expected and had longer survival than females. Diets with better nutritional quality resulted in adults with bigger wings. Asaia sp. and Escherichia coli resulted in better nutrition and developmental parameters and seemed to be the best bacterial candidates to future studies using symbiont-based control. The diet quality was measured and presented different protein and carbohydrate amounts. Bacteria had the lowest protein and carbohydrate rates, yeasts had the highest carbohydrate amount and microalgae showed the highest protein content. Larvae fed with microalgae seem not to be able to process and store these diets properly. Larvae were shown to be able to process yeast cells and store their energetic components efficiently. Conclusion Together, our results point that Ae. aegypti larvae show high plasticity to feed, being able to develop under different microorganism-based diets. The important role of Ae. aegypti in the spread of infectious diseases requires further biological studies in order to understand the vector physiology and thus to manage the larval natural breeding sites aiming a better mosquito control.

“…Despite the important consequences of food on the life history traits of immature mosquitoes, few studies (Olivo et al , Agnew et al , Arrivillaga and Barrera , Couret et al , Levi et al ) have attempted to assess this effect separately from larval density of Ae. aegypti .…”

“…In these studies that represented more realistic conditions, food availability varied with time, depending on the amount added daily and on the consumption rate of the studied larvae. The most important effects of food scarcity were an extension in development time and a decrease in the size of adults, while an increase in mortality was observed only at very low food levels (Olivo et al , Arrivillaga and Barrrera , Couret et al , Romeo Aznar et al ).…”

Few studies have assessed the effects of food scarcity or excess on the life history traits of Aedes aegypti (L.) (Diptera: Culicidae) independently from larval density. We assessed immature survival, development time, and adult size in relation to food availability. We reared cohorts of 30 Ae. aegypti larvae from newly hatched to adult emergence with different food availability. Food conditions were kept constant by transferring larvae each day to a new food solution. Immature development was completed by some individuals in all treatments. The shortest development time, the largest adults, and the highest survival were observed at intermediate food levels. The most important effects of food scarcity were an extension in development time, a decrease in the size of adults, and a slight decrease in survival, while the most important effects of food excess were an important decrease in survival and a slight decrease in the size of adults. The variability in development time and adult size within sex and treatment increased at decreasing food availability. The results suggest that although the studied population has adapted to a wide range of food availabilities, both scarcity and excess of food have important negative impacts on fitness.

“…This study investigates the mosquito Aedes vigilax (Skuse) for effects of larval nutrition on Ross River virus (RR) vector competence, dissemination barriers and a method for estimating transmission without the use of a vertebrate host. Factors such as the density of mosquito larvae (Baqar et al, 1980), temperature of water (Van den Heuvel, 1963) and nutrition during the larval stages affect the rates of growth (Marcovitch, 1960;Olivo et al, 1979) and survival (Baqar, 1980;McCombs, 1980), as well as the size, life span, fecundity (Christophers, 1960) and lipid content of resultant adult mosquitoes (Clements, 1992). Larval nutrition also affects the ability of adult mosquitoes to become infected with and transmit arboviruses.…”

Effects of larval nutrition on vector competence of the mosquito Aedes vigilax (Skuse) (Diptera: Culicidae) from Townsville, north Queensland, for Ross River virus (RR) were examined. Larvae were reared on three different diets to create three significantly different size classes of adult mosquito. These were fed on serial dilutions of RR and then sampled on alternate days so the progression of the virus through the mosquito could be examined. No differences of vector competence could be attributed to larval nutrition. Barriers to infection and the correlation between infection rate, viral titre and transmission of RR by Ae. vigilax were also examined. The mesenteronal barrier was the only infection barrier expressed. No correlation between viral titre and transmission was detected, but a strong correlation was found between salivary gland infection and transmission rate. From this it was possible to estimate that 98.7+/-1.3% of Ae. vigilax with infected salivary glands transmit RR.
