摘要：于2009年5月调查了肇庆市国有林业总场属下的肇庆市北岭山林场、怀集县大坑山林场、封开县大水口林场和2个苗圃基地的降香黄檀病虫害。结果表明，这些林场的降香黄檀人工林幼树的嫩梢和叶片都有不同程度的病虫为害，主要是螟蛾类蛀梢害虫引起；叶部病害的症状观察和室内病原菌分离培养结果表明，病害是由炭疽病菌和细菌性穿孔病引起。目前，降香黄檀林地的病虫害危害程度较轻，未见严重的危险性病害。

Abstract: The infection of pests and pathogens of Dalbergia odorifera were investigated in the 2 year old plantations of Beiling Forest Farm in Zhaoqing City, Dakengshan Forest Farm in Huaiji County, Dashuikou Forest Farm at Fengkai County and two nurseries in May 2009. It was found that twigs and leaves of Dalbergia odorifera were infested by pests to different extent. Based on the observation and identification, it was confirmed that the insect on twigs was branch borer of Pyralididae, and the diseases of leaves were caused by Colletotrichum sp. and bacteria. In general, the disease severity was slight and no serious pests were found.
