Effect of Temperature on Hatching Rate of Nannophya pygmaea eggs (Odonata: Libellulidae)
Abstract
The hatching rate of the eggs of Nannophya pygmaea Rambur, an endangered dragonfly species in Korea, was experimented in different temperature conditions (10, 15, 20, 25, and 30℃) in laboratory. N. pygmaea eggs were collected from female adults inhabited a small wetland in Mungyong-si, Kyeongsangbuk-do, Korea, in July 2006. The hatching rate was evaluated from the number of hatched nymphs for the period of 100 days. As a result, the hatching rates were 83, 89, and 76% at 20, 25, and 30℃, respectively, however, eggs were not hatched at 10℃ and 15℃ during the experiment period. The derived thermal threshold for egg hatching was 14.3℃, which is relatively higher than the values of other temperate dragonflies.
