| 摘 要： | 红树林是自然分布于热带和亚热带海岸潮间带的木本植物群落 ,具有造陆、护岸、护堤等功能 ,是维持海岸生态平衡的重要生态系统。由于人为破坏和干扰 ,使红树林的植物种类由多变少 ,由高大乔木变为矮小灌丛 ,湿地生态系统功能日益衰退 ,遭受各种有害昆虫的危害 ,严重影响其生长 ,极大限制红树林各种功能的发挥。国外主要有澳大利亚、泰国、印尼、新加坡及香港等国家和地区先后报道白骨壤(Avicenniagerminans)、海漆 (Excoecariaagallicha)和桐花树 (Aegicerascorniculatum)叶片遭到鳞翅目(Lepidoptera)昆虫为害 ;古巴大量的大红树苗木受蛀干害虫为害 (Westetal.,1 985 ;Whittenetal.,1 986)。国内仅林鹏 ( 1 985 ;1 993;1 997)、汪维礼 ( 1 988)等报道了福建、浙江秋茄 (Kandeliacandel)被藤壶 (Balanussp .)、卷叶蛾 (Tortricidae)和茎腐病危害 ,并提出红树林病虫害防治是营造红树林实践应该引起重视的问题。丽绿刺蛾 (Latoialepida)是红树林主要食叶害虫之一...

| Abstract: | Latoia lepida is one of the main defoliators for the mangrove forest. The survey in the forest revealed that L.lepida principally distributed on the middle and upper parts of crown, the position soaked by seawater for short time gradually decreased from the internal beach to the external beach, the average injured percentage was 46.3% on the internal beach (high tide position), and the average injured percentage was only 13.8% on the external beach (middle tide position). The seawater soak-resistant experiment indicated that the influence of different soak times existed the extremely marked different on L.lepida survival rate, the population mortality rate increased with the increase of soaking time after soaking for more than 4 h, the population mortality reached the peak at the time of soaking for 8 h, and then the population survival rate stabilized to a certain level. The difference was not obvious among various-generation larval adversity resistance, the difference was evident among various-instars larval adversity resistance, the adversity resistance of larvae on seawater soaking was the main reason for the larval population distribution law and the large outbreak of L.lepida in the forest. |
