Termite Species Distribution and Flight Periods on Oahu, Hawaii.

Termites are economically-important structural pests, costing residents of Hawaii over $100 million annually. On Oahu, the last published termite swarming survey occurred from 1969 to 1971, and the last termite hand-collection survey occurred from 1998 to 2000. To contribute data on termite occurrences on Oahu, a light-trap survey took place from February 2011 to September 2012, and a hand-collection survey occurred from September to November 2012. Formosan subterranean termite, Shiraki, swarming was compared over the duration of the study, finding peak swarming in May 2011. alate activity density was regressed with environmental factors, finding a negative correlation with average wind speed and a positive correlation with average rainfall. (Wasmann) alates were observed in April, June, and July 2011 and in June 2012. Four species of termites were found in the hand-collection survey of 44 sites: (Snyder) ( = 8/44), ( = 2/44), Light ( = 1/44), and sp. ( = 1/44). This study contributes to distribution data for termite species on Oahu and records alate activity for two important termite pests.
