Abstract

Many native insect species in China, has shifted host to exotic eucalyptus and caused significant damage to plantations. Two wood-boring insects, Batocera horsfieldi Hope, 1839 (Coleoptera: Cerambycidae) and Endoclita signifier Waller, 1856 (Lepidoptera: Hepialidae), were the most severe on eucalyptus in southern China. Incidences of infestation of B. horsfieldi and En. signifer on eucalyptus and its relationships between canopy density, altitude, tree age and variety of eucalyptus were studied using the method of sampling survey in Hezhou City, Guangxi Zhuang Autonomous Region of China. Results showed that B. horsfieldi preferred the habitat with higher canopy density of eucalyptus. Incidence of infestation of B. horsfieldi was positively correlated with the age of eucalyptus, and negatively correlated with the altitude. There was no significant correlation between the incidence of infestation of B. horsfieldi and the variety of eucalyptus. Endoclita signifer preferred the habitat with higher canopy density of eucalyptus. Incidence of infestation of En. signifer had no significant correlation with the age of eucalyptus and the altitude. There was significant correlation between the incidence of infestation of En. signifer and the variety of eucalyptus. These results are an important base for the control (e.g., resistance screening) of the two wood-boring insects.
