Abstract:

 [Objectives]  To determine whether Lindera glauca (Sieb. Zuce) BL can repel oviposition by Phthorimaea operculella. [Methods]  The effects of different parts of L. glauca; intact fruit, damaged fruit, roots, and concentrations of hexane extracts from damaged fruit from 0.25 to 4.0 gE/mL, on the oviposition preferences of P. operculella were tested under laboratory conditions. The repellent effect of damaged fruit was also tested in storage. The effects of four volatiles (citral, linalool, geraniol,α-phellandrene) at concentrations from 0.00075 to 0.012 g/L on the oviposition preferences of P. operculella were also tested in the laboratory. [Results]  Although intact fruit, damaged fruit and roots could all repel oviposition, the oviposition deterrence percentage (ODP) achieved by damaged fruit was higher than that achieved by intact fruit or roots; 20 g of broken fruit had an ODP of 93.7%. The repellent activity of hexane extracts from broken fruit increased with concentration. The ODP of 20 g of broken fruit reached 82.5% in storage. Concentrations of 0.003 to 0.012 g/L of citral, 0.012 g/L of linalool, 0.00075 to 0.012 g/L of geraniol, and 0.003 to 0.012 g/L ofα-phellandrene, all had an extremely strong deterrent effect on oviposition. [Conclusion]  L. glauca and its volatiles have repel oviposition by P. operculella.
