“…Limonene is a chiral molecule. We have screened the enantiomer R‐(+)‐limonene for larvicidal activity and confirmed the earlier reporter's observation that limonene has good mosquito larvicidal potential (Pavela, , ; Santos et al, ; Wang et al, ). Additionally, the insecticidal activity of EOs containing limonene as one of the active ingredients have been reported (Govindarajan et al, ; Pavela, ).…”

“…Some of the EOs showing insecticidal activity where γ‐terpinene as one of the chemical constituents are Origanum vulgare subsp. hirtum , Coridothymus capitatus , Satureja thymbra (Karpouhtsis et al, ), Satureja hortensis L. (Pavela, ), Magnolia denudate (Wang et al, ), Eucalyptus camaldulensis and E. urophylla (Cheng et al, ), Citrus reticulata Blanco (Sutthanont et al, ). R‐(+)‐limonene has been reported to be present in Spilanthes acmella (Padhan et al, ), and is a major constituent in several citrus oils like Citrus sinensis (Murthy et al, ), Citrus limettioides (Jayaprakasha et al, ), and Citrus karna Raf (Malhotra et al, ).…”

Most of the essential oils (EO) known for mosquitocidal activity contain terpenes as part of their chemical constituents. In this study, four monoterpenes namely γ‐terpinene (T), R‐(+)‐limonene (L), carvacrol (C), and trans‐anethole (A) were screened against late third instar Aedes aegypti Linn. larvae singly and in combination to find out the synergistic interaction. The monoterpenes γ‐terpinene, R‐(+)‐limonene, trans‐anethole, and carvacrol showed larvicidal activity with LC50 values of 9.76, 11.88, 50.19, 48.57 ppm and LC90 values of 16.99, 17.78, 65.21, 75.02 ppm, respectively for Ae. aegypti when tested individually. Prepared binary combinations at LC20 values and studied the synergistic interactions based on cotoxicity factor (CTF) and found that all the binary combinations showed synergistic interactions (CTF > 20). Further, the binary (1:1), ternary (1:1:1), and quaternary (1:1:1:1) terpene combinations on equal weight basis were prepared, evaluated against Ae. aegypti larvae and synergistic interactions were studied by Wadley's method. Among the eight combinations two combinations viz. LC (LC5010.42 ppm) and LA (LC5011.86 ppm) were showing synergistic interactions (R > 1.5) and others were exhibiting additive effect (1.5 ≥ R > 0.5) and none of the combinations showed antagonism (R < 0.5). Among the two methods used the Wadley's method found suitable when combinations were made on an equal weight basis. The two binary combinations found in this study are promising synergistic mixtures which has scope in designing mosquito larvicidal EOs by enriching the EOs with terpenes or by producing EO combinations with these terpenes as chemical constituents in the correct proportions.

Essential oils and their components as an alternative in the control of mosquito vectors of diseaseMore than half of the human population is exposed to mosquito-borne infections. Climate change and the emergence of strains resistant to traditionally used insecticides have motivated the search of new agents for mosquito population control. Essential oils have been effective repellents and larvicidal agents. The aim of this work was to review research studies conducted in recent years on the larvicidal activity of essential oils and their components against Aedes, Anopheles and Culex mosquitoes, as well as the latest reports about their possible mechanism of action. Más de la mitad de la población humana está expuesta a contraer infecciones transmitidas por mosquitos. La falta de tratamientos y vacunas eficaces para muchas de estas enfermedades hace que su control dependa principalmente de la utilización de agentes insecticidas (1). Los individuos que habitan en las áreas tropicales están más expuestos a contraer enfermedades transmitidas por vectores y este riesgo ha aumentado en otras zonas debido a la globalización (2).Culex, Aedes y Anopheles son vectores de diversas enfermedades, como la filariasis, el dengue, la malaria, y otras. Culex quinquefasciatus está presente en vastas regiones tropicales del mundo, es la principal plaga doméstica en muchas áreas urbanas y está implicada en la transmisión de muchos agentes patógenos, entre ellos, el causante de la filariasis linfática. Esta enfermedad está ampliamente distribuida en las zonas tropicales, con alrededor de 120 millones de personas infectadas en todo el mundo (3).

In order to develop an environment-friendly botanical mosquito larvicide alternative to the chemical larvicides, extracts were made from the leaves of Hyptis suaveolens, Lantana camara, Nerium oleander, and Tecoma stans with three organic solvents such as methanol (ME), chloroform (CH), and petroleum ether (PE) using a Soxhlet extractor. The plant extracts were screened for larvicidal activity individually and in combination against the larvae of Aedes aegypti and Culex quinquefasciatus as per WHO protocol. Among the extracts, the maximum larvicidal activity was shown by the PE extract of L. camara (LC 10.63 mg/L) followed by the PE extract of T. stans (LC 19.26 mg/L), ME extract of N. oleander (LC 35.82 mg/L), and PE extract of H. suaveolens (LC 38.39 mg/L) against Cx. quinquefasciatus. In the case of Ae. aegypti, the PE extract of T. stans showed maximum activity with LC value of 55.41 mg/L followed by H. suaveolens (LC 64.49 mg/L), PE extract of L. camara (LC 74.93 mg/L), and ME extract of N. oleander (LC 84.09). A blend of these four extracts resulted in a combination with corresponding LC values of 4.32 and 7.19 mg/L against Cx. quinquefasciatus and Ae. aegypti. The predator safety factors were 12.55 and 20.88 for Gambusia affinis with respect to Aedes and Culex larvae for the extract combination. Chemical constituents in extracts were also identified by FT-IR and GC-MS data. The present investigations suggest the possible use of this blend of botanical extracts as an ideal ecofriendly, larvicide against Ae. aegypti and Cx. quinquefasciatus larvae.
