人工栽培菜用枸杞病虫害发生规律研究

Occurrence Rule of Main Diseases and Pests on Artificially Cultivated Lycium barbarum L.

2013—2014年通过抽样调查、镜检调查等方法,监测了北京地区人工栽培菜用枸杞的病虫害种类及发生规律,为进一步研究防治技术奠定基础。结果表明:北京地区人工栽培菜用枸杞发生的主要病虫害种类共有12种,包括虫害9种,病害3种。虫害以枸杞负泥虫、枸杞蚜虫、枸杞龟甲、枸杞锈螨、枸杞瘿螨危害严重,枸杞负泥虫发生高峰在8—9月,枸杞蚜虫发生高峰在5月、9月,枸杞龟甲发生高峰为6—8月,枸杞锈螨发生高峰为5月、9月,枸杞瘿螨发生高峰在5—6、8—9月;病害以枸杞炭疽病、枸杞灰斑病危害严重,枸杞炭疽病发生高峰为7—8月,枸杞灰斑病发生高峰为7—9月。

Main disease and pest species and their occurrence regularities on artificially cultivated Lycium barbarum L. were investigated in Beijing from 2013 to 2014,in order to lay the theoretical foundation for studying pest control technology. The results showed that there were 12 kinds of major disease and pest species,including nine kinds of pests,and three kinds of diseases. Among the pests,Lema decempunctata,Aphis sp.,Casslda sp.,Aculops lycii Kuang and Aceria palida damaged seriously. The occurrence peak of Lema decempunctata was in Aug and Sep,the occurrence peak of Aphis sp. was in May and Sep,the occurrence peak of Casslda sp. was in Jun to Aug,the occurrence peak of Aculops lycii Kuang was in May and Sep,and the occurrence peak of Aceria palida was in May to Jun and Aug to Sep. Among the diseases,Colletotrichum gloeosporioides Penz and Cercospora lycii Ell. et Halst caused serious damage. The occurrence peak of Colletotrichum gloeosporioides Penz was from Jul to Aug,and the occurrence peak of Cercospora lycii Ell. et Halst was from Jul to Sep.
