Efficacies of five edible mushroom extracts as odor baitsfor resting boxes to attract mosquito vectors: A field studyin Samut Songkhram Province, Thailand

摘要

Effective trapping of adult mosquitoes in the wild can reduce the spread of deadlyhuman pathogens, such as Plasmodium species causing malaria. The efficacy of this strategydepends on the capacity of the trap to attract and retain insects, and specific odorants suchas octenol in mushrooms are strong attractants for mosquitoes. In this study, we assessed theefficiency of a resting box baited with five different extracts from local edible mushrooms,Pleurotus ostreatus, Thaeogyroporus porentosus, Volvariella volvacea, Pleurotus sajorcaju,and Lentinus edodes, for attracting mosquito vectors in Samut Songkhram Province,Thailand. Extracts were used in identical “resting box” at 50, 100, and 200 mg/mL per box.Compared to the unbaited resting box (control), only traps containing 200 mg/mL of L. edodesextract captured significantly more mosquitoes (16.00 ± 3.61 vs. 7.00 ± 1.00 per resting boxper night, p<0.05). Attraction efficacy did not increase progressively with tested amount formost extracts. These findings indicate that L. edodes extract can be used as an inexpensive,non-toxic, and locally sourced attractant to increase the efficacy of mosquito control.
