title: [Effects of illumination and cold storage on development and reproduction of Carposina niponensis].
abstract: The study showed that with the prolongation of illumination, the development duration of Carposina niponensis was shortened. Illumination had most obvious influence on the larval diapause rate, which was the minimum under 15 h of illumination and increased when illumination was prolonged and shortened. Other important parameters such as fecundity, larval weight, hatching rate, leaving rate and emergence rate reached their peak when the illumination duration was 13 to approximately 17 h. Therefore, the optimal illumination duration for the development and reproduction of C. niponensis was about 15 h. The duration of cold storage had no significant influence on the duration of pupa, longevity of adult, and duration of egg. But, the emergence rate, fecundity, and hatching rate were reduced when the cold storage duration exceeded 7 days. Therefore, pupae and eggs should not be stored at low temperature for a long period.
