“…The larvicidal mechanism of tannins is related to their ability to inactivate adenosine, enzymes and cell proteins 46,47 . Hydrolyzed tannins are usually amorphous compounds, hygroscopic, yellow-brown in colour and soluble in water (boiling water) to form colloidal solutions instead of natural solutions.…”

Background and Objective: Diseases caused by microbes vectored by mosquitoes are still a health problem in tropical countries today.DHF and Malaria are the two primary diseases vectored by mosquitoes, the morbidity and mortality rates have increased in low countries until now. However, the best way to control these two diseases is to control vectors, namely mosquitoes. Research has been conducted to determine the bioactive content and larvicidal activity of local plant extracts of North Sulawesi. Materials and Methods: The clove and trumpet flower samples were obtained from Minahasa, while the nutmeg samples were obtained from Sitaro Regency. Empirically, people use plant parts to repel mosquitoes. Extraction of plant simplicia was carried out by the maceration method. Qualitative and quantitative methods carried out the phytochemical content analysis. Qualitative analysis uses Harborneʼs (1996) method while qualitative analysis uses the UV Vis Spectrophotometer method. Toxicity tests were carried out on mosquito larvae developed in the laboratory. Results: The results showed that combining clove leaf extract, nutmeg flesh extract and trumpet flower synergistically increased the bioactive content. Flavonoids increased in the combination of extracts compared to partial extracts. The combination of extracts showed the highest toxicity to mosquito larvae (LC 50 : 22.541 mg LG 1 ), while the lowest was the partial extract of clove leaves with LC 50 (54.965 mg LG 1 ). Conclusion:The combination of extracts showed the best toxicity activity on mosquito larvae. Research on bioactive characteristics and toxicity in adult mosquitoes needs to be carried out in the future.

“…The preliminary test exhibited that water-ethanol fraction possessed the highest larvicidal activity on Ae. aegypti larvae with larval death of 96.67% at 2000 ppm concentration (Redo et al, 2019). The effect of aqueous, ethanol and acetone extracts of Terminalia catappa leaves against the larvae and pupae of Aedesa egypti mosquito was studied.…”

Mosquito larvae control is essential to prevent mosquito borne diseases such as dengue, Zika, filariasis and chikungunya. Plant extract has the larvicidal properties with less toxicity to other living creatures and no resistance compared to synthetic chemical pesticides. Effect of hot water leaf and bark extract of a forest tree species (Swietenia mahagoni) against the 3rd instar larvae of Culex quinquefasciatus and Aedes aegypti was studied in vitro using five different concentrations (1-5%) of hot water leaf and bark extracts of Swietenia mahagoni. It was observed that, 5% concentrated hot water leaf extract was the most toxic killing 70% larvae of Culex quiquefasciatus and 50% larvae of Aedesa egypti after 24 hours exposure. Similarly, 5% hot water bark extracts killed 65% and 55% of Culex quiquefasciatus and Aedes aegypti larvae respectively. The minimum LC50, LC90 and LC95 values of hot water leaf extract of Swietenia mahagoni against Culex quinquefasciatus Say and Aedes aegypti (L.) with 95% confidence limits were 2.662, 6.968, 8.70 and 2.128, 4.964, 6.054 respectively after 72 hours of exposure. In hot water bark extract of Swietenia mahagoni against Culex quinquefasciatus Say and Aedes aegypti (L.) with 95% confidence limits after 72 hours of exposure minimum LC50, LC90 and LC95values were 1.780, 6.540, 9.458 and 1.370, 4.570, 6.430. The present investigation revealed the possible utilization of hot water leaf and bark extract of Swietenia mahagoni to control mosquito borne disease. Further study is needed to know the active ingredients of the leaf and bark extract of the experimented plant. Asian J. Med. Biol. Res. 2022, 8 (2), 94-102

“…The results of this study showed 100% mortality of Aedes aegypti larvae at a concentration of 2%. According to another study, Redo et al, (2019) said that the larvicidal activity of the water-ethanol fraction of ketapang leaves at a concentration of 1800 ppm was comparable to temephos. Another study regarding ketapang leaf extract which was tested on Aedes aegypti larvae showed an LC50 value of 166.00 ppm (Unnikrishnan, 2014).…”

Diseases caused by Aedes aegypti mosquitoes can be controlled with vectors in the form of larvicide administration, but if it is excessive, it causes environmental pollution and causes larval resistance so that natural larvicides are needed. Ketapang leaves are tested to determine the effectiveness of larvicides against Aedes aegypti larvae. To determine the effectiveness of the ethanol extract of ketapang leaves (Terminalia catappa L.) with TWEEN dilution on the mortality of Aedes aegypti larvae. The research is experimental with the research design used is posttest only controlled group design. This design compares the experimental group with the control group. The groups used were groups K (+) and K (-), and the TWEEN/PEG treatment group which contained ketapang leaf extract with a concentration of 1,5% and 2%, respectively. The sample of Aedes aegypti larvae used was instar III IV. Normality, Kruskal-Wallis, Mann-Whitney and Probit tests are used for data processing. Mortality was highest with his PEG treatment at 1,5% and lowest with TWEEN at 2%. The effect of ethanol extract from ketapang leaves (Terminalia catappa L.) with TWEEN diluent was the same as PEG on the mortality of Aedes aegypti larvae. The ethanol extract of ketapang leaves (Terminalia catappa L.) with dilutions of TWEEN and PEG was less effective than abate.
