ABSTRACT
Mosquito-borne diseases are a major public health issue, especially in tropical and subtropical regions. In this study, wecompared the efficacy of Volvariella volvacea (Bull. ex Fr.) mushroom, an edible, commercially available mushroomspecies grown in Thailand with octenol (1-octen-3-ol) as a standard substance to kill larvae and attract adult, includingAedes aegypti Linnaeus and Culex sitiens Wiedemann, mosquitoes. Five concentrations of extract, including 120,12, 1.2, 0.12, and 0.012 mg/l were selected to test the effectiveness of killing mosquito larvae. Three concentrationsof extract, including 100, 10, and 1 mg/l were selected to test the effectiveness of adult female mosquito attraction.The result of the comparison of the larvicidal efficacy between V. volvacea extract and octenol in each concentration,showed that there were differences in number of dead larvae in almost all the concentrations in testing with octenol(p < 0.05), while in the adult mosquito attraction bioassay, V. volvacea extract attracted the highest number of adultfemale A. aegypti and C. sitiens at the 10 mg/l concentration followed by 1 and 100 mg/l, as well as the effect ofoctenol. The statistical comparison found that the efficiency of attracting A. aegypti and C. sitiens mosquitoes in allthe concentrations of V. volvacea extract was different from octenol (p < 0.05).
