Abstract

Under the condition of natural infection in the wild, the authors analyzed the resistance degree and compensation ability of 20 tree species to Capitophorus rhamnoides Zhang using the recovery rate of leaf roll of sprouts as insect resistance index. The result indicated that tree species except for peach, russianolive and elm were the hosts for C. rhamnoides Zhang, Among all the sea buckthorn species, the varieties and coenospecies were susceptible to C. rhamnoides, but species and subspecies were relatively resistant to C. rhamnoides. There was significant difference in the recovery rate of leaf roll among varieties. At the harm peak, tree species with low leaf roll rate, such as Chengse and Lengguo etc., could recover completely due to their own harm resistance compensation ability and natural enemies, presenting a strong resistance to C. rhamnoides. Whereas, tree species with high leaf roll rate, such as Yousheng, Chuyi and Wulangemu etc., which were severely damaged, could recover no more than 50% for their limited harm resistance and compensation ability, suggesting they were weak in resisting to C. rhamnoides. The recovery rates of leaf roll of apple tree and Yunnan Sea buckthorn were 55.6% and 50%, respectively, which were moderately resistant to C. rhamnoides.
