Abstract

To assess effects of cold treatment on pupation and emergence of the mulberry longicorn beetle, Apriona germari, the larvae, which ceased feeding, were exposed to three different temperature regimes (2.5, 5 and 7.5$^{\circ}C$) and preservation periods (50, 80, and l10 days). The results indicated that pupation and emergence rates of A. germari were highest at $7.5^{\circ}C$ for 110 days, 40.7% and 37.0%, respectively, demonstrating that the effect of cold treatment on metamorphosis was approximately 3 to 4 fold stronger than that of nontreatment.
