摘　　要：为弄清惠东县红树林秋茄Kandelia obovata大量枯梢的原因,2019-2021年持续对该地区的秋茄进行野外调查,并采集秋茄嫩梢枝条带回实验室饲养。最终确定了秋茄枯梢现象是由一种新害虫窄茎瘤蛾Nola angustipennis所致。窄茎瘤蛾一年多代,以幼虫钻蛀危害秋茄的嫩芽和嫩梢,老熟幼虫织茧化蛹于其中。本文对窄茎瘤蛾的成虫、幼虫、蛹形态特征进行了描述,并对其危害特点进行了阐述,为其准确鉴定及科学防控提供支持。In order to understand the causes for the large number of dieback of Kandelia obovata in Huidong County, Huizhou City, Guangdong Provice, continuously observation were taken in this area from 2019 to 2021, and the tender points of K. obovata were collected and brought back to the laboratory for rearing. Finally, Nola angustipennis, a new pest of K. abovata was found, which larva burrows into the tender points and causes dieback. Several generations can occur a year, the mature larvae weave cocoons and pupate in them. The descriptions of adults, larva and pupa were presented, as well as introductions of damage characteristics, those can be as a basis for accurate identification and scientific control.
