Abstract

Research on host selection behavior of Anoplophora chinensis.

Abstract

To investigate the host selection of Anoplophora chinensis (CLB) to the plant species which have been largely introduced on Yangtze River Delta, Carya illinmoensis, Acer sp., 8 tress species (varieties) of Quercus sp., and such indigenous species as Salix babylonica and Melia azedarach often damaged by CLB, were selected to determine the feeding and oviposition preference of CLB. The result was as follows: feeding area, feeding traces and oviposition number of CLB had significant difference among different host plants. The CLB adults preferred to feed on Acer saccharum, and next on A. palmatum and M. azedarach while females preferred oviposition on S. babylonica and M. azedarach, next on Acer saccharum and A. palmatum, but no eggs observed on A. negundo 'Aurea'. It was concluded that CLB's feeding host selection was not consistent with the oviposition preference behavior. So in order to diminish the damage of CLB, when in exotic tree species introduction, the mixed stands CLB adults prefer to feed on and to lay egg on should be avoided.
