Late season commercial mosquito trap and host seeking activity evaluation against mosquitoes in a malarious area of the Republic of Korea

摘要

Field trials evaluating selected commercially available mosquito traps variously baited with light, carbon dioxide, and/or octenol were conducted from 18-27 September 2000 in a malarious area near Packyeon-ri (Tongil-Chon) and Camp Greaves in Paju County. Kyonggi Province, Republic of Korea. The host-seeking activity for common mosquito species, including the primary vector of Japanese encephalitis, Culex trilaeniorhynchus Giles, was determined using hourly aspirator collections from a human and propane lantern-baited Shannon trap during hours when temperatures exceeded 15CC. The total number of mosquitoes and number of each species captured during the test was compared using a block design. Significant differences were observed for the total number of mosquitoes collected, such that, the Mosquito MagnetTM with octenol > Shannon trap > ABC light trap with light and dry ice > Miniature Black Light trap (manufactured by John W. Hock) >= New Jersey Trap > ABC light trap with light only. Significantdifferences in numbers collected among traps were noted for several species including: Aedes uexans (Meigen). Anopheles lesteri Balsas and Hu. An. sinensis Weidemann. An. sineroides Yamada. An. yatsushiroensis Miyazaki. Culex pipiens pollens Coquillett L., Cx. orienlalis Edwards and Cx. tritaeniorhynchus. Host-seeking activity for most common species showed a similar bimodal pattern. Results from these field trap evaluations can significantly enhance current vector and disease surveillance efforts especially for the primary' vector of Japanese encephalitis. Cx. trttaeniorhynchns.
