日光温室枣树昆虫群落及时间动态研究

Studies on insect community characteristics and time dynamics of juju be tree in greenhouse

  • 摘要: 对日光温室枣树昆虫群落指数及时间动态聚类分析研究的结果表明,日 光 温室枣树主要害虫防治可分为4阶段,其中2月、5月和6月昆虫群落处于极不稳定状态,优势 种枣瘿蚊Contarinia sp.、截形叶螨Tetranychus fruncatus发生量较大且易暴发 ,为化学防治关键时期。而1年其他时间则应视情况尽量采用农业、物理和生物等防治措施 ,以保护天敌,充分发挥天敌的控制作用。

     

    Abstract: Based on the method of fuzzy clustering,the characteristic indexes and the time dynamic of jujube insect community in greenhouse were studied.The results show that the control times of main insect pests may be divided into four p hases.The phases of February,May and June are the key phases of chemical control,during which the insect community is hardly steady,the quantity of superior species Contarinia sp.and Tetranychus fruncatus becomes larger,causing thes e pest insects to break out easily.Conversely,in order to protect the nature enemies and give full play to their action,the methods of agriculture,physics and biology must be used to control the insect pests and in the rest time of a year.
