The mosquitoes Aedes aegypti and Culex quinquefasciatus (Diptera: Culicidae) are important vectors of several arboviruses, and are relevant public health problems. Conventional control, using chemical larvicides have selected resistant Culicidae populations and caused negative effects on the environment and human health. However, the use of plant extracts has represented a sustainable alternative for insect control. Popularly known as Xiriri, Mauritiella armata (Mart.) Burret (Aceraceae) is an abundant palm tree in Vereda ecosystems and has economic and social importance. In this study, the aim was to evaluate the larvicidal activity of the aqueous extract (AE) leaves of this plant on Ae. aegypti and Cx. quinquefasciatus larvae. The mortalities of larvae were analyzed after treatment with four concentrations of the extract, comparing with a negative control using mineral water. The AE promoted 100% efficacy against Ae. aegypti larvae at 7.9 mg/mL. The lethal concentration to promote 90% mortality of Cx. quinquefasciatus larvae was estimated at 30.57 mg/mL. After chromatographic analyses, flavonoids, catechin and carbohydrates were detected. AE from M. armata leaves presented high larvicidal activity against Ae. aegypti and Cx. quinquefasciatus, and represents a promising alternative to be used in vector control.

Introduction: A research had been carried out to analyze the larvicidal activity of the ethanol extract of kemuning leaves (Murraya paniculata (L.) Jack.) against Aedes aegypti L. larvae. Method: The research began with extracting yellow leaves (Murraya paniculata (L.) Jack.) With a modified maceration method using 80% ethanol solvent until a thick extract is obtained, then a preliminary test is carried out to obtain LC5 and LC95 so that 5 concentrations of yellow leaf extract (Murraya paniculata (L.) Jack.) can be obtained which can be used as a real larvicide test. The actual larvicide test was carried out with 7 treatments, namely 1 negative control using Tween 80, 5 test treatments namely 1000 bpj yellow leaf extract, 3000 bpj, 5000 ppm, 7000 ppm and 9000 ppm and 1 positive control using Temephos 2 bpj. Observation of the test results was carried out after 24 hours by counting the number of larvae deaths in each treatment group. Result: The data obtained were analyzed by using probit analysis and obtained LC90 of yellow leaf extract (Murraya paniculata (L.) Jack.) which is 8330,291 bpj. The results showed that the yellow leaf extract (Murraya paniculata (L.) Jack.) was effective as a larvicidal activity with LC5 of 1000 bpj and LC95 of 9000 bpj.

Objectives: The activity of two different leaf extracts of Lantana indica and Vitex negundo is tested against the 3rd and 4th instar Culex quinquefasciatus larvae to evaluate the potency of the extracts as a larvicide and to find an ecologically sustainable alternative to chemical insecticides. A bioinformatics screening approach was performed to evaluate the in vivo results.Methods: The obtained larvae’s from nearby water sources were tested with N, N-diethyl-meta-toluamide (DEET) as the positive control which is the commercial chemical mosquito repellent and the solvents used for the respective plant extracts act as the negative control. Petroleum ether (PE), ethyl acetate (EA) and an aqueous (AQ) extract were prepared for both L. indica and V. negundo extracts, and its larvicidal activity was tested. A docking based approach was used to study the inhibitory effect of known active compounds from L. indica and V. negundo against acetylcholine esterase (AChE) and sterol binding protein as targets.Results: On comparing the results between three plants extract for its larvicidal activity, the EA extract of V. negundo and L. indica is found to be potent with a low LC50 value. Further, the docking studies between active compounds of L. indica and V. negundo with AChE and Sterol binding protein as targets showed that the compound tangeritin-1 had a good docking score compared to DEET and could be a natural alternative for larvicidal activity in the mosquito.Conclusion: Individual activity of tangeritin-1 could be further studied with mosquito mortality studies and molecular simulations and develop tangeritin-1 as a potential larvicidal compound for commercial use.
