福清市松突圆蚧发生发展变化分析

The Analysis of Hemiberlesia pitysophila Proliferation in Fuqing City

对福建省福清市2003—2016年马尾松松突圆蚧调查监测数据进行分析研究,结果表明:不同林分改造措施(皆伐、择伐、带状疏伐套种阔叶树、块状皆伐营造混交林、建立隔离带、幼林修枝间伐等)对松突圆蚧治理影响显著,发生面积、发生率、发生程度呈逐年下降趋势;不同生态区位松突圆蚧发生率、危害程度因不同林分性质差异明显,根据不同生态区位疫情危害程度因地制宜分类实施采取重度重点优先、由外延向内部逐步推进的治理方法成效显著;花角蚜小蜂天敌防治和生物仿生制剂的施用对福清市松突圆蚧的生物防治发挥了重大作用,因此,以生物防治为主的综合措施对指导福清市松突圆蚧的监测预警与发生防治有积极的借鉴意义。

The data that is from survey and monitor about Hemiberlesia pitysophila proliferation of masson pine between 2003 and2016 in Fuqing City,Fujian Province,has been researched.And relevant results are below：1.total area,frequency and extent of occurrence declines gradually as year passes,because of various transform measures to standing forest,including clear cutting,selective cutting,broad-leaved trees from strip thinning,mixed forest from clear cutting in patches,isolation strip and intermediate cuttings to pruning of young growth; 2.the rate and detriment extent of hemiberlesia pitysophila appearance are diverse in different geographical places of the city due to variety of standing forest discrepancy,and based on difference detriment extent of in various ecological zone bit,it is obviously efficient to take suitable approaches that from emphasis to non-emphasis,from outer space to inner space; 3.the usage of natural enemy prevention by coccobius azumai tachikawa cultivation and biological biomimetic preparations has showed the critical value to biological Hemiberlesia pitysophila in Fuqing City; 4.the measures based on biological prophylaxis and treatment has positive reference necessity for monitoring,early warning and prevention of Hemiberlesia pitysophila proliferation in Fuqing City.
