摘要：Herbivore exclusion trials of Acacia mearnsii De Wild, were established in Fujian Province. China from 1994 to 1996. Exclusion was effected by spraying half the trees with insecticide. The incidence and damage of insect species and growth performance of the trees were assessed at fixed intervals. Surveys for insects in plantations were also conducted. Over 70 insect species were found on A. mearnsii, all of which were indigenous except the cottony cushion scale (Icerya purchasi Maskell). This study identified a number of potentially serious pests of A. mearnsii and presented some evidence for effective natural biological control. Although insect pest numbers were generally low in the trials, which may have been partly due to natural biological control, serious effects of herbivore damage on tree survival and productivity were detected.
