| Abstract |
Females of Anopheles albimanus mosquito are known to prefer floating cyanobacterial mats over open water for oviposition. We used Solid Phase MicroExtraction (SPME) devices on-site to trap substances volatilized from these two environments, followed by analysis by GC-MS (gas chromatograph-mass spectrometer), In enclosed headspace field microcosms, an unidentified C-15 aliphatic alcohol was persistently found over cyanobacterial mats as compared to open water. Based on this finding, we conducted oviposition experiments using a commercially available compound, n-pentadecanol, close in molecular weight and mass spectral pattern to the unknown C-15 aliphatic alcohol, The results indicate a tendency of female mosquito to oviposit more eggs in containers with the tested chemical as compared to water and blank. |
