Observations from a mosquito collecting trip to the Marshall, Caroline, and Mariana Islands of Micronesia and the Solomon Islands and Vanuatu of the Melanesia are summarized. Aedes albopictus has expanded its range to Truk, and is now firmly established on northern Guadalcanal. The presence of Ae. aobae on Pentecost was confirmed. New colonies have been established of 2 populations of Ae. albopictus, 3 of Ae. hebrideus, and 1 each of Ae. marshallensis and Ae. pernotatus. Eggs from Ae. saipanensis, Ae. pandani and Ae. quasiscutellaris did not hatch in response to established procedures, and adults of Ae. hakansonni, Ae. albolineatus and Ae. guamensis could not be induced to feed in captivity. The literature for all Aedes (Stegomyia) species and their involvement in dengue transmission is summarized for the areas visited.
