低温对橘小实蝇羽化的影响
The effect of low temperatures on eclosion rates in the fruit fly Bactrocera dorsalis
摘要
Abstract
[Background] Bactracera dorsalis ( Hendel) ( Diptera: Tephritidae) is an important quarantine pest, with wide occur-rence and causing serious damage. The effect of low temperatures on eclosion of the fruit fly B. dorsalis is not reported. [Method]The effect of low temperatures on eclosion of B. dorsalis were studied in the laboratory by setting different temperatures ( 8℃, 4℃, 0 ℃ and -4 ℃) and time treatments (12 h, 18 h and 24 h). [Result] The emergence rate of B. dorsalis decreased from 100.0%under normal temperature (28℃) to 6.7% at 0℃. The period of eclosion time also increased, from 9.0 days under normal temper-ature (28 ℃) to 12.5 days at 0 ℃. When the temperature was -4 ℃, B. dorsalis was unable to emerge. [Conclusion and signifi-cance] B. dorsalis demonstrated poor cold tolerance. This is useful for defining the distribution limits for B. dorsalis.关键词
