“…However, the development of gel preparation for repellent should be continued further to provide a pharmaceutical dosage form that comfort to use and is safe for humans and the environment. Currently, some herbs also tested the effectiveness for repellents such as Duranta plumieri [28] and Acalyphia indica [29].…”

Objective: The purpose of this research is to prepare a cinnamon bark essential oil gel preparation, determines the physical characteristic and physical stability during storage, and examines the activity of mosquito repellent from the best gel preparation. Methods: The formulations of gel were made with variations in the concentration of Carbopol 940 (0.5%, 1.5%, and 2%) contain 1% of cinnamon bark essential oil. The gel evaluated physical characteristics and physical stability. The parameters of organoleptic, homogeneity, and pH are analyzed descriptive, while the viscosity, the spreadability, and the gel adhesion were analyzed using one-way ANOVA at the level of confidence of 95%. The best gel tested its effectiveness as compared to the negative control and product innovator (which used DEET as an active compound) as a positive control. The activity of repellent was determined by an Aedes aegypti mosquito for 6 h with 2 hands respondents. The effectiveness of repellent protection is calculated by the percentage of protection power. Results: The studies showed that all the gel preparations qualified the organoleptic, homogeneity, and pH parameters. The viscosity, gel adhesion, and spreadability are also stable during storage. Conclusion: Based on the results, the best gel is the formula I which has mosquito repellent activity effective for 6 h like DEET.

Being vector of West Nile Virus and falariasis the control of Culex quinquefasciatus is likely to be essential. Synthetic insecticide treatment is looking most effective for vectors mosquito control. However, these products are toxic to the environment and non-target organisms. Consequently, ecofriendly control of vectors mosquito is needed. In this regard botanical insecticide is looking more fruitful. Therefore, the present research aimed to investigate the effectiveness of methanolic extract and various fractions, including, n-hexane, ethyl-acetate, chloroform, and aqueous fraction, obtained from methanolic extract of Ailanthus altissima, Artemisia scoparia, and Justicia adhatoda using separating funnel against larval, pupal, and adult stages of Culex quinquefasciatus. The larvae and pupae of Culex quinquefasciatus were exposed to various concentrations (31.25-1000 ppm) of methanolic extract and its fractions for 24 hours of exposure period. For knock-down bioassay (filter paper impregnation bioassay) different concentration of the methanolic extract and its various fractions (i.e. 0.0625, 0.125, 0.25, 0.5 and 1mg/mL) were applied for 1 hour exposure period. The results were statistically analysed using standard deviation, probit analysis, and linear regression. The R2 values of larvae, pupae, and adult range from 0.4 to 0.99. The values of LC50 (concentration causing 50% mortality) for late 3rd instar larvae after 24 hours exposure period range from 93-1856.7 ppm, while LC90 values range from 424 -7635.5ppm. The values of LC50for pupae range form 1326.7-6818.4ppm and and values of LC90 range from 3667.3-17427.9ppm, respectively. The KDT50 range from 0.30 to 2.8% and KDT90 values range from1.2 to 110.8%, respectively. In conclusion, Justicia adhatoda may be effective for controlling populations of vector mosquito.

BACKGROUND: Mosquito control is essential in preventing mosquito-borne diseases. Natural substances originated from plants possessed the great potential of insecticidal properties, the resistance occurs at a slower rate compared to the synthetics, with less toxicity to other living creatures. AIM: This study aimed to identify the fraction of ketapang leaf (Terminalia catappa L) with larvicidal activity on Aedes aegypti instar III larvae, the concentration of ketapang active leaf fraction comparable to temephos, and Lethal Concentration 50 (LC50). METHODS: This study was experimental in vitro. The experiment was performed with five different concentrations of ketapang leaf water-ethanol fraction, i.e. 1200 ppm, 1400 ppm, 1600 ppm, 1800 ppm, 2000 ppm. Observation of morphological damage of mosquito larvae was conducted with the microscope and ImageJ application. Data analysis was performed using One Way ANOVA. LC50 was determined with probit analysis. RESULTS: Phytochemical screening revealed a water-ethanol fraction of ketapang leaf contained tannin, saponin, and flavonoid compounds. The water-ethanol fraction with 1800 ppm concentration possessed significant larvicidal effect comparable to temephos. Probit test revealed an LC50 value of 1563.082 μg/ml. CONCLUSION: Water-ethanol fraction of ketapang leaf possessed high biolarvicidal activity against Ae. aegypti larvae instar III comparable to temephos.
