The mosquito species Aedes aegypti is one of the main vectors of arboviruses, including dengue, Zika and chikungunya. Considering the deficiency or absence of vaccines to prevent these diseases, vector control remains an important strategy. The use of plant natural product-based insecticides constitutes an alternative to chemical insecticides as they are degraded more easily and are less harmful to the environment, not to mention their lower toxicity to non-target insects. This review details plant species and their secondary metabolites that have demonstrated insecticidal properties (ovicidal, larvicidal, pupicidal, adulticidal, repellent and ovipositional effects) against the mosquito, together with their mechanisms of action. In particular, essential oils and some of their chemical constituents such as terpenoids and phenylpropanoids offer distinct advantages. Thiophenes, amides and alkaloids also possess high larvicidal and adulticidal activities, adding to the wealth of plant natural products with potential in vector control applications.

Aedes aegypti is the main vector of dengue fever that most commonly occurred in Indonesia. The application of botanical insecticides is being developed as an alternative vector control. Botanical components have been reported as the potential alternative to inhibit the process of oviposition and fecundity suppression. This study aims to determine the oviposition deterrent activity and ovicidal effects of ethanol extract of Pometia pinnata leaves against Aedes aegypti. Oviposition deterrent assay was conducted on twenty bloodfed females in a cage (40 cm x 40 cm x 40 cm). One treated oviposition trap and one control oviposition trap were placed in the opposite corner of the cage. Four replicates were performed for each concentration. The eggs were counted and analyzed after 72 hours of trial. Ethanol extract of Pometia pinnata leaves have antioviposition effect on female mosquitoes Aedes aegypti at 400 ppm (effective repellency / ER = 56.38%; oviposition active index/OAI = -0.39) and 500 ppm (ER = 66.4%; OAI = -0.49). In the ovicidal assay, twentyfive eggs are used for determination ovicidal effect and five replicates were performed for each concentration. The hatched larvae were collected and counted daily. The ethanolic extract of Pometia pinnata leaves at 0.05%, 0,1%, 0.15%, 0.2%, and 0.25% concentration have ovicidal activity of 11%, 28%, 87%, 94%, and 98% against Aedes aegypti eggs, respectively. This study revealed that the ethanol extract of Pometia pinnata leaves could be a potential alternative in controlling the dengue vector.

BACKGROUND: Aedes aegypti is one of the most vicious mosquitoes, known for its role in several deadly diseases, including dengue fever and Zika. Several strategies have been developed over decades to prevent vector-borne diseases; one of them is insecticide to control the mosquito population. However, this strategy would not last long due to the elevation of resistance, environmental problem, and some issues regarding human health. Natural products have become major options to combat the glitches. Lemongrass (Cymbopogon citratus) has known for its toxic effect on mosquito larva. AIM: The objective of this study was to assess the effect of C. citratus extract against fourth instar of A. aegypti larvae. METHODS: Three extract concentrations, 2.5%, 5%, and 7.5%, were used. The larvicide activity was evaluated at 2, 4, and 6 h. Our data indicated that all concentrations contributed to increase larvae mortality. RESULTS: Lethal Concentration (LC) 50 and LC90 were achieved at 2.5% and 4.1% of extract, respectively. CONCLUSION: C. citratus  extract has a larvicide activity against fourth instar of A. aegypti.
