Exposure to stress during an insect’s larval development can have carry-over effects on adult life history traits and susceptibility to pathogens. We investigated the effects of larval nutritional stress for the first time using field mosquito vectors and malaria parasites. In contrast to previous studies, we show that larval nutritional stress may affect human to mosquito transmission antagonistically: nutritionally deprived larvae showed lower parasite prevalence for only one gametocyte carrier; they also had lower fecundity. However, they had greater survival rates that were even higher when infected. When combining these opposing effects into epidemiological models, we show that larval nutritional stress induced a decrease in malaria transmission at low mosquito densities and an increase in transmission at high mosquito densities, whereas transmission by mosquitoes from well-fed larvae was stable. Our work underscores the importance of including environmental stressors towards understanding host–parasite dynamics to improve disease transmission models and control.

“…The above strategies can be used in the IVM context along with well-established control tools, such as selective microbial and plant-borne pesticides effective against immature mosquitoes, oviposition deterrents, insecticide-coated clothes and other surfaces for personal protection, spatial repellents reducing human-vector contact such as microencapsuled insecticide paint formulation, as well as synthetic and plant-borne repellents [23,[62][63][64][65][66][67][68][69].…”

Towards Malaria Elimination - A Leap Forward

The effective and reliable management of malaria vectors is still a global challenge. Recently, it has been noted that the first vaccine against Plasmodium falciparum malaria, RTS,S/AS01 showed only transient protection, particularly in infants, and rapid resistance has been developing to artemisinin-based drugs. Therefore, the control of malaria mosquito vectors according to strategies of integrated vector management (IVM) is receiving emphasis. A rather wide number of novel mosquito control tools have been tested, including attractive toxic sugar baits, eave tubes, nano-synthesized pesticides loaded with microbial-and plant-borne compounds, biocontrol agents with little nontarget effects, new adult repellents, oviposition deterrents, and even acoustic larvicides. However, their real-world applications remain limited. Most National Malaria Control Programs in Africa still rely on indoor residual spraying (IRS) and long-lasting insecticidal nets (LLINs) to reduce malaria incidence but generally have insufficient impact on malaria prevalence. Here, we focus on facts, trends, and current challenges in the employment of the above-mentioned vector control tools in the fight against malaria. We emphasize the needs for better vector control tools used in IVM to overcome the challenges posed by outdoor transmission and growing levels of insecticide resistance, which are threatening the efficacy of LLINs and IRS.

“…While documentation of IP vector impact is beginning to accumulate, evidence of disease reduction is still missing. A large-scale trial of the clinical impact of IPs on Chagas is reportedly in the initial stage [ 7 ]. However, at this point there is no documentation of afforded protection against VBDs by current IP products at the individual, household, or community level.…”
