Abstract
Abstract Seasonal flight patterns of the bluegreen aphid (BGA), Acyrthosiphon kondoi Shinji (Homoptera: Aphididae) were studied. BGA had flight peaks twice a year in spring and autumn, BGA flight appeared to be diurnal. The main period of activity extended from 5 am to 7.30 pm. The accumulated spring and autumn flight peaks lasted 422 Degree Days (DD) and 351 DD (2.9 and 2.4 BGA generations) respectively. Accumulated DD between the median of spring and autumn flights, and the autumn and following spring flight, was 1667 and 1676 DD; this corresponds to 11.5 and 11.6 BGA generations respectively. The use of DD for predicting BGA flight is discussed.
