Abstract: CAHATOL, MARIA ISABEL B. Effect of Mint and Apple Cider Vinegar Combination against Aedes albopictus and Culex quinquefasciatus Larvae. Undergraduate Thesis, Doctor of Veterinary Medicine. Cavite State University, Indang, Cavite. April 2016. Adviser: Chester Joshua Saldarla, DVM, MSc. A study was conducted to determine the effect of mint and apple cider vinegar combination against Aedes albopictus and Culex quinquefasciatus larvae. The mosquitoes were reared in the laboratory and four hundred third instar larvae of Aedes albopictus and Culex quinquefaciatus were exposed to different concentrations of the combination ranging from 20, 40, 60, 80 and 100%. The larval mortality was observed after 3, 6, 9, 12, 15, 18, 21 and 24 hours under the laboratory conditions. Results revealed that the third instar larvae of Aedes albopictus registered a mortality of 40% after 6 hours of exposure at 40% concentration of the combination while at 9 hour exposure, 93, 97 and 100% mortality were observed and recorded at concentration of 60, 80 and 100%. On the other hand, it was found that 40% extract effectively killed 63% of Culex quinquefasciatus larvae and were totally killed (100%) when treated with 80% extract at 9 hours period. No mortality was recorded at 20% concentration. The difference between the concentrations 40, 60, 80% at 6 and 9 hours post-exposure were statistically significant in both species. The mortality of the larvae increased with increasing the concentration of the combination. Higher larval mortality (93%) was noted for Aedes albopictus compared to Culex quinquefasciatus (87%) at 60% concentration at 9 hour interval. At the same hour, faster mortality was observed for Culex quinquefasciatus (100%) than Aedes albopictus (97%) after exposure to 80% concentration. No statistical difference found on the mortality between the two different species of mosquitoes used. The study revealed that the mint and apple cider vinegar combination have larvicidal activity against third instar of Aedes albopictus and Culex quinquefasciatus.

The study revealed that the mint and apple cider vinegar combination have
larvicidal activity against third instar of Aedes albopictus and Culex quinquefasciatus.
