Mosquitoes carry several human diseases, including dengue fever, malaria, filariasis, chikungunya and Japanese encephalitis. These diseases are major public health issues worldwide, especially in tropical and subtropical areas, and cause millions of deaths each year. In this study, we examined the ability of Hypsizygus tessellatus extract to kill larvae and attract adult Aedes aegypti and Culex sitiens mosquitoes; these species are important vectors in coastal areas of Samut Songkhram province in Thailand. We used 5 extract concentrations, namely 120, 12, 1.2, 0.12 and 0.012 mL/L, for larvicidal tests and 3 concentrations (10-4, 10-5 and 10-6 g/mL) to test for attraction of adult mosquitoes. We found that H. tessellatus extract was not effective against Ae. aegypti larvae, while it promoted minimal death of Cx. sitiens larvae. We found that the ability of H. tessellatus extract to attract adult female mosquitoes was different at all concentrations. While our research showed that this mushroom extract had little ability to attract mosquitoes, it could be developed to further enhance mosquito lure efficiency, especially for Ae. aegypti.
