Two methods were used to estimate the effective accumulated heat (K) and threshold development temperature (To) of the green lacewing, Chrysopa phyllochroma Wesmael, under 7 constant temperatures. The results were as follows: 1) by means of Li Chao's ‘optimum seeking method’, T 0 of eggs, larvae, and pupae are 14. 20, 11. 55 and 8. 27°C respectively, K of them are 53. 82, 151. 58 and 243. 85 day‐degrees respectively; 2) by means of Li Dianmo's ‘rapid estimation method’, T 0 of eggs, larvae, and pupae are 14. 33, 12.18 and 8. 38°C respectively, K of them are 54. 41. 157. 62 and 245. 21 day‐degrees respectively; 3) based on linear regression equation and the logistic curve equation, the formula for estimating development rates of different development stages at certain temperatures has been established.
