Abstract: Casuarina spp. is a main part of the coastal shelter forest in southeast China, but the damage of Casuarina spp. forest is mainly caused by Anoplophora chinensis. One of the effective means to control this pest is breeding resistant varieties of Casuarina. Taking the population density, attacking rate, eclosion rate and the growth as indices, the resistance to A.chinensis of 48 C. equisetifolia clones in the germplasm banks at Huian in Fujian province were studied based on investigation and artificial inoculation in the forest during 2010-2012. The results showed that Hui13, Hui76, Hui83 were resistant to A. chinensis with the average population density of larva less than 0.12, attacking rate was lower than 12 percent, and 0 eclosion rate. No more than 20 percent of larvae were able to develop into adults on these clones by artificial inoculation.Hui58, Hui88 were sensitive to A. chinensis, with the average population density of larva more than 1.0, attacking rate and eclosion rate exceeded 66 percent and 35 percent, respectively. It was up to 60 percent of larvae developed into adults successfully by artificial inoculation.
