“…Given that volatile oils are traditional sources of natural insecticides or larvicides [5] [6], whose action on Ae. aegypti has been attributed to terpenoids [7 -9], and whose composition and/or concentration vary according to many factors such as plant species, this work aimed at comparing the larvicidal activity of essential oils extracted from three aromatic medicinal plants against Ae.…”

This work aimed at comparing larvicidal activity of essential oils extracted from the dried leaves of Alpinia speciosa, Cymbopogon citratus, and Rosmarinus officinalis against Ae. aegypti larvae. The larvae were observed for 4 h and at 24 h according to a completely randomized design with three replications and the following concentrations [μl/ml]: 0.25, 0.5, 1.0, 1.5, 2.0, 2.5, and controls were distilled water, and commercial standard citral, camphor, eucalyptol, α-pinene, and β-myrcene. The essential oil of C. citratus had the lowest LC₅₀ (0.28) and LC₉₀ (0.56) values, followed by that of A. speciosa (0.94 and 1.2, resp.) and of R. officinalis (1.18 and 1.67, resp.), and only the commercial standards citral and α-pinene were larvicidal.

“…In the long term, these parasitic nematodes will eventually result in a drastic reduction of the mosquito populations and in a considerable decrease in the malaria transmission rates. A study done in Pochutla, Oaxaca, Mexico, an endemic area of malaria, showed that Romanomermis iyengari , one strain of the Mermithid species, is very useful in the larval control of A. pseudopunctipennis [87]. The continuous application of around 3000 Romanomermis iyengari per meter square, on a 30,000 meter square area of A. pseudopunctipennis breeding sites, for a period of nine months, resulted in 46% to 100% decrease in the infection rates of the malaria parasite, and in a 38.1% to 99.8% reduction in the Anopheles larvae [87].…”

Introducing Romanomermis culicivorax , another strain of the Mermithid species, in certain A. albimanus larval habitats in Colombia also showed considerable abilities of this parasitic worm to establish itself in these areas, recycle within 27 months, reduce the A. albimanus larval population, and result in a progressive decrease in malaria transmission, mainly among school children [88].…”

The call for malaria control, over the last century, marked a new epoch in the history of this disease. Many control strategies targeting either the Plasmodium parasite or the Anopheles vector were shown to be effective. Yet, the emergence of drug resistant parasites and insecticide resistant mosquito strains, along with numerous health, environmental, and ecological side effects of many chemical agents, highlighted the need to develop alternative tools that either complement or substitute conventional malaria control approaches. The use of biological means is considered a fundamental part of the recently launched malaria eradication program and has so far shown promising results, although this approach is still in its infancy. This review presents an overview of the most promising biological control tools for malaria eradication, namely fungi, bacteria, larvivorous fish, parasites, viruses and nematodes.

“…Additional mosquito-parasitic mermithids examined for biological control include R. iyengari Welch (1964) and S. spiculatus Poinar and Camino (1986). Field releases have demonstrated the ability of mermithids to reduce mosquito populations (P erez-Pacheco et al, 2005;Achinelly and Micieli, 2009;Abagli et al, 2012).…”

Superparasitism is a common phenomenon in mosquito-parasitic mermithid nematodes. Multiple nematodes are needed in a single host to produce males. Host selection behavior and intraspecific competition among Romanomermis iyengari and Strelkovimermis spiculatus were investigated against their host, Culex pipiens pipiens in laboratory experiments. In a choice assay between previously infected and uninfected host larvae, infectious preparasites of both nematode species could distinguish not only between infected and uninfected hosts, but even between different parasite loads in showing a strong preference for uninfected hosts or hosts with a low parasite load. Host heart rate declined briefly immediately after parasitism. Superparasitism resulted in increased parasite mortality. Scramble competition within mosquito larvae for limited host nutrients, coupled with a skewed sex ratio favoring males, is assumed to lead to parasite population decline and subsequently toward host-parasite population equilibrium. The ability of mermithid preparasites to accurately assess parasite load likely plays an important role in host population dynamics and regulation.
