A samples survey of Camellia oleifera forests were carried out in two counties, four towns, nine villages in Liuzhou, and the result shows that the pest and diseases existing in C. oleifera branches include Arbela bailbarana Matsumura, Casmara patrona Meyrick, Bacchisa atritarsis Pic, Aeolesthes induta Newman, Tettigoni- idae, Corticium scutellare, C. oleifera tumor disease, Loranthus yadoriki Sieb and L. sparasitica （Linn.）. The main pest diseases are as follows： Arbela bailbarana Matsumura and Bacchisa atritarsis Pic made most harm, whose harmfulness is from a moderate extent to a severe one;Corticium scutellare and Camellia oleifera tumor disease, whose harmfulness is from a slight extent to a severe one. This demonstrates that some kinds of pest and diseases in C. oleifera branches severely harm the producing areas of C. oleifera, all of which should need to be intensively controlled and prevented.
