Abstract

This experiment was conducted to investigate the seasonal fluctuation of population density and the life history of Adoxophyes sp .. Under field-cage conditions, smaller tea tortrix had 4-5 generations a year. The average periods from egg to adult emergence were 43.7 days in spring and fall, and 35.2 days in summer. The average longevity of adults was 7.0 days in spring and fall, and 6.3 days in summer. The average numbers of egg masses and eggs laid by a female were 1.8 and 40.4 m spring and fall, and 2.3 and 49.5 in summer, respectively. Population density of smaller tea tortrix estimated by sex pheromone trap and light trap showed four peaks in each late May, late June, middle August and late September. The number of individuals caught by sex pheromone trap was 2~4 times as large as that by jight trap. Smaller tea tartrix overwimered in larval stage in southern region af Korea.
