Developmental Ecology of Persimmon Fruit Moth, Stathmopoda masinissa Meyrick (Lepidoptera: Stathmopodidae)

감꼭지나방 (나비목: 감꼭지나방과)의 발육생태

Persimmon fruit moth, Stathmopoda masinissa, collected from roadside persimmon trees planted as shade trees in yeongdong area was used to investigate their developmental ecology under laboratory conditions; $25\pm$ $1^{\circ}C$, 16L : 8D and 85% RH. Developmental periods for eggs, larvae, and pupae were 7.4, 34.8 and 15.5 days, respectively. The duration for each larval instar from the 1st to the 5th was 3.5, 4.2, 5.2, 6.5 and 15.4 days, respectively, and the head capsule width of corresponding stage was 0.20, 0.40, 0.65, 0.87 and 1.07 mm. Rates of pupation and emergence were 68.0 and 59.9%, respectively. Longevity of adult males was 6.2 days while that of females was 10.1 days. Average fecundity was 25.4 eggs.
