为了解云南省丽江市大棚草莓病虫害发生情况，于2023年9月至2024年8月，选择3个试验点，采用随机5点取样法开展草莓病虫害调查，记录草莓植株的生长和病虫害发生情况，在病虫害发生高峰期每隔7 d观察1次，记录发病率、病情指数、虫株率和虫情指数。结果表明，研究区大棚草莓病虫害主要有灰霉病、白粉病、炭疽病、根腐病、蚜虫、红蜘蛛等。发生情况方面，灰霉病、白粉病、根腐病和炭疽病在试验点2的病情指数分别为46.50、40.66、36.67和34.07，在试验点3的病情指数分别为40.83、36.33、35.80、34.55，在试验点1的病情指数分别为33.17、35.83、29.15、29.92；红蜘蛛和蚜虫在试验点2的虫情指数分别为38.18和32.67，在试验点3的虫情指数分别为31.60和34.00，在试验点1的虫情指数分别为30.74和28.50。侵染规律方面，灰霉病为害草莓地上部所有部位，以果实受害最重；白粉病多以菌丝或分生孢子侵染草莓叶片和果实，严重时也会为害叶柄、花萼和果梗等；根腐病主要为害草莓根部，发生严重时根系腐烂使全株枯死；蚜虫成虫多在嫩心叶、叶背、叶柄处吸食汁液，造成草莓叶片扭曲变形、卷缩；红蜘蛛多聚集于草莓叶片背面，为害初期产生白色斑点，逐渐转为红色，严重时呈现铁锈状；生长环境（温度、湿度、通风条件等）、草莓品种特性（丰产性、抗病虫性等）、栽培管理（肥水管理、种植管理等）均会对病虫害发生程度产生一定影响。病虫害防治方面，因地制宜采取相应措施，综合利用农业、物理、生物、化学等防治措施防治灰霉病、白粉病等病害及红蜘蛛、蚜虫等虫害。本文为类似地区草莓病虫害调查及防控提供参考。

To understand the occurrence of diseases and pests in greenhouse strawberry in Lijiang City, Yunnan Province, strawberry disease and pest investigations were carried out at three experimental sites from September 2023 to August 2004 using the random five-point sampling method. The growth status and the occurrence of diseases and pests on strawberry plants were recorded. During the peak occurrence period of diseases and pests, observations were carried out every 7 days, and the incidence rate, disease index, percentage of infested plants, and pest index were documented. The results showed that the main diseases and pests of greenhouse strawberries in the study area included gray mold, powdery mildew, anthracnose, root rot, aphids and spider mites. In terms of occurrence status, the disease indices of gray mold, powdery mildew, root rot and anthracnose at experimental site 2 were 46.50, 40.66, 36.67 and 34.07, respectively; those at experimental site 3 were 40.83, 36.33, 35.80 and 34.55, respectively; and those at experimental site 1 were 33.17, 35.83, 29.15 and 29.92, respectively. The insect indices of spider mites and aphids at experimental site 2 were 38.18 and 32.67, respectively; those at experimental site 3 were 31.60 and 34.00, respectively; and those at experimental site 1 were 30.74 and 28.50, respectively. In terms of infection regularity, gray mold infested all above-ground parts of strawberry plants, with the most severe damage to fruits. Powdery mildew mostly infected strawberry leaves and fruits by mycelia or conidia, and could also damage petioles, calyxes and pedicels in severe cases. Red stele root rot mainly damaged strawberry roots, and severe infection would cause root rot and subsequent whole plant death. Adult aphids sucked sap from tender heart leaves, leaf undersides and petioles, resulting in twisting, deformation and curling of strawberry leaves. Spider mites mostly gathered on the leaf undersides of strawberry; at the early infestation stage, white spots appeared on the leaves and gradually turned red, and the leaves showed a rust-colored appearance in severe cases. Growth conditions (e.g., temperature, humidity, ventilation), strawberry cultivars (e.g., yield potential, disease and pest resistance) and cultural management (e.g., fertilizer and water management, cultivation management) all had certain effects on the occurrence severity of diseases and pests. In terms of disease and pest control, targeted measures should be adopted according to local conditions, and agricultural, physical, biological and chemical control measures should be comprehensively applied to control diseases such as gray mold and powdery mildew, as well as insect pests such as spider mites and aphids. This study provides a reference for the investigation, control and prevention of strawberry diseases and pests in similar areas.
