Evaluation of the Mosquito Magnet Pro trap with and without 1-octen-3-ol for collecting Aedes albopictus and other urban mosquitoes.

During the summer of 2004, 3 field studies were performed to evaluate the Mosquito Magnet Pro trap with and without 1-octen-3-ol (octenol) in enhancing collections of Aedes albopictus (Skuse). At Field Site 1, 1,501 Ae. albopictus were collected, with 89% collected with octenol. At Field Site 2, 570 Ae. albopictus were collected, with 86% collected with octenol. Aedes albopictus collections were significantly enhanced in both preliminary Field Trials 1 and 2 (P < 0.03). There was a 3-fold increase in collections of Anopheles punctipennis and an 18-fold increase in collections of Ae. vexans at Field Site 2. At Field Site 3, 5,571 were Ae. albopictus, with 75% collected with octenol. Results from the 3rd field trial indicated that Ae. albopictus (P < 0.03), Coquillettida perturbans (P < 0.01), and Ochlerotatus triseriatus (P < 0.03) were significantly more attracted to traps supplemented with octenol than to traps operating without octenol. There was a 2.4-, 6-, and 3.5-fold increase in collections of Ae. albopictus with octenol in Field Trials 1, 2, and 3, respectively.
