- Abstract
- This study was conducted to estimate relationship between temperature and egg development
of Nannophya pygmaea, an endangerd dragonfly species in Korea, using eight different
temperature conditions (17, 20, 22, 25, 28, 30, 33, and 36℃). Eggs of N. pygmaea were collected from
female adults inhabited a small wetland in Mungyeong-si, Gyeongsangbuk-do, Korea, in June 2007.
As a result, hatching rates were 2.86, 17.09, 24.32, 39.67, 34.43, 40.57, 44.79, and 1.75% at 17, 20,
22, 25, 28, 30, 33, and 36℃, respectively. The nonlinear model of the temperature related to egg
development was well fit to the modified Sharpe and DeMichele model. The derived lower developmental
threshold temperature for egg hatching was 14.02℃(y=0.005988x-0.084, r2=0.99), and the
derived optimal development temperature was 30~35℃.
