黄土高原温室黄瓜斑潜蝇发生规律研究

Studies on outbreak regularity of cucumber leafminer in greenhouse in Loess Plateau

  • 摘要: 通过大田调查与室内试验相结合的方法,研究了黄土高原温室黄瓜斑潜蝇发生规律。结果表明,黄土高原温室黄瓜斑潜蝇有4种,美洲斑潜蝇(Liriomyza sativae)为优势种,在温室内年发生8~10 代,10月中旬~11月下旬为第一个发生高峰期,3月下旬至5月中旬为第二个发生高峰即防治关键时期。以各种虫态在温室内取食为害度过冬天,不能在田间自然条件下越冬。斑潜蝇幼虫在黄瓜植株上的垂直分布具有明显的层次性,以中下部密度最大,占90%以上。温度超过45℃持续2h 或土壤相对湿度达100%超过2h,蛹化率均为0。温室种植模式、栽培面积及天敌等是影响斑潜蝇种群数量的主要因素。

     

    Abstract: The field investigation and lab experiment were conducted to study the outbreaking characters of cucumber leafminer in greenhouse on Loess Plateau. The results show that four species of cucumber leafminer are found in greenhouse on Loess Plateau. Among them, Liriomyza sativae is the dominant species. The insect grows for 8~10 generations per year in sunshine greenhouse. Two injurious peaks happen from mid October to late November and from late March to mid May, respectively,and the second peak is the key time to control the insect. The insect not being able to live through winter outside the greenhouse has to stay in the greenhouse. The vertical distribution of leafminers on cucumber is obviously in stratification, in mid and lower strata more than 90% of the larvae disperses. The eclosion rate of larvae is zero when the temperature is higher than 45℃ for 2 hours or the mositure of soil is 100% for 2 hours. The plantation mode, culturing area, and natural enemy are important factores affecting the population of cucumber leafminer.
