摘要:

为掌握云南荔枝病虫害发生种类及主要病虫害发生规律,精准防控荔枝病虫害,于2019—2021年在云南省5个荔枝主栽区采用实地调查、专题调研的方法,全面调查荔枝病虫害种类及为害情况,并用圆形分布统计方法对主要病虫害发生规律进行分析。结果表明,云南省荔枝常见病害7种,以荔枝霜疫霉病、荔枝炭疽病和荔枝叶斑病为害为主;虫害31种,以荔枝蒂蛀虫、荔枝蝽、吸果夜蛾类为害为主。5—8月是荔枝蒂蛀虫、荔枝霜疫霉病、吸果夜蛾类害虫和荔枝蝽集中发生时期,4—9月是荔枝炭疽病集中发生时期,3—9月是荔枝叶斑病集中发生时期。目前,3—9月是云南荔枝主要病虫害集中发生时期,该时期是云南荔枝病虫害防治关键时期。

Abstract:

The study aims to observe and sort out major diseases and insect pests of litchi in Yunnan Province, and to give scientific guidance and solution to the prevention and control of litchi diseases and insect pests. A field investigation was conducted in five different litchi-planting areas of Yunnan from 2019 to 2021. The circular distribution statistical method was used to sort out the commonly occurred diseases and major economic pests of litchi. Based on the results, there were 7 common diseases of litchi in Yunnan, mainly Peronophythora litchii, Colletotrichum spp., and Phomopsis guiyuan. 31 insect pest species were observed, mainly Conopomorpha sinensis, Tessaratoma papillosa and fruit moths. The peak seasonal time of major diseases and insect pests (Conopomorpha sinensis, Peronophythora litchii, fruit moths and Tessaratoma papillosa) was from May to August. The Colletotrichum spp. was on peak from April to September, and Phomopsis guiyuan was active from March to September. At present, main diseases and insect pests of Yunnan litchi are concentrated from March to September, which is the key period for the prevention and control of diseases and insect pests.

Key words: litchi, Yunnan, species of pests and kinds of diseases, harmful situation, occurrence regularity, circular distribution statistics
