| 摘 要： | 对黔东南州茯苓主产区的白蚁发生及危害情况进行定点调查.结果发现,黔东南州全州茯苓均发生白蚁危害,以黑翅土白蚁、黄胸散白蚁最为常见,且种群密度高,对茯苓的危害性最大;白蚁主要危害山冲种植的茯苓,坡塝地带白蚁危害相对较轻.由于白蚁危害具有隐蔽性、易传播和扩散蔓延特点,防治较为困难,部分药农使用高效、高残留农药灭杀白蚁,导致茯苓农药残留超标,影响品质.建议从开展高效低残留防治白蚁药物的筛选研究、开展白蚁防治技术研究、开展科学防治白蚁的技术推广工作3个方面着手防治白蚁.

| Abstract: | This study aimed to investigate the occurrence and damage of white ants in main Poria cocos-producing areas of Qiandongnan Miao and Dong Autonomous Prefecture by site survey.The results indicated that white ant damage occurred throughout the prefecture.Specifically,Odontotermes formosanus and Reticulitermes flaviceps were the most common species with high population density possessing the greatest danger to Poria cocos production.White ants mainly hazarded Poria cocos planted in thrust,while those planted in slope zone were slighted hazarded.White ant damage was difficult to prevent and control due to its high concealment,easy propagation and wide spread.Applying efficient high -residue pesticides to kill white ants would result in excessive residue of pesticides and affect the quality of Poria cocos.Therefore,white ants should be controlled by screening efficient low-residue drugs,developing white ant prevention and control technologies and popularizing scientific control means. |
