Abstract:In order to explore the influence of temperature on the development and reproduction of codling moth, Cydia pomonella (L.), the developmental duration, survivorship, and fecundity of this pest were investigated in the laboratory under 15, 20, 25, 28, 31 and 34 ℃, and then constructed life tables of the experimental population of codling moth at different temperatures. The developmental durations decreased with the temperature increasing from 15 ℃ to 31 ℃, the developmental duration for the whole generation at 15, 20, 25, 28, 31 ℃ was 112.0, 46.8, 33.3, 29.6, 26.2 days, respectively. The development of codling moth was inhibited at 34 ℃, the developmental duration for the whole generation increased to be 31.4 days. Adult lifespan decreased with the temperature increasing. The maximum number of eggs laid per female was 92.7 at 25 ℃, oviposition of fertile eggs failed at 15 and 34 ℃. The analysis of life table showed that population trend index (I) were larger than 1 at 20-31 ℃, the intrinsic rate of increase (rm) and population trend index were the highest at 25 ℃, with the values being 0.0972 and 39.70, respectively. The results showed that the most suitable temperature for this pest was 25 ℃ or so, when temperature was too high or low, it was detrimental to reproducing of codling moth.
