榕母管蓟马生物学特性及防治措施

2005～2007年对台州市区榕母管蓟马生活史及消长规律的观察表明,榕母管蓟马在台州一年发生9～10代,主要以成虫在被害叶内越冬,越冬成虫于3月上旬开始活动,4～6月、10～11月为危害高峰期,7～8月高温季节虫口明显减少,害虫世代重叠现象明显,且每代所需时间随季节变化而变化.加强苗木检验检疫和田间管理,采取生物防治、化学防治和人工防治等措施可以有效控制该虫的危害.

Biological characteristics and control of Gynaikothrips ficorum

Gynaikothrips ficorum is the main pest to Ficus microcarpa.The observation on life cycle,growth and decline pattern of the Gynaikothrips ficorum in Taizhou during 2005 to 2007 indicated that the thrips had 9~10 generations per year in Taizhou.The adults stay inside the damaged leaves over the winter,and they began to activate in the first ten-day of March.During April to June and October to November was the peak of damage.The number reduced in the high temperature season of July to August,and the overlap of generations was rather serious.The time each generation needed was different with the seasons.The pest could be efficiently controlled with biological,chemical and artificial control methods.
