小麦蚜虫田间调查及监测技术

小麦蚜虫是世界范围内小麦生产中一类重要害虫。针对麦蚜世代历期短、繁殖力强,具有趋光、趋化及迁飞等生物学及行为习性;在田间多呈聚集分布,且麦蚜易受寄主植物抗性、天敌、气象因素及农田生态条件等生物与非生物因素影响等发生为害特点,本文阐述了我国小麦蚜虫田间调查、监测技术及防治策略,以期为我国小麦蚜虫综合防控提供基础科学支撑。

Techniques for field survey and monitoring of wheat aphids in China

Aphids are globally important pests of wheat crops. More and more research has led to a clearer understanding of their biology, life habits and demographics. Wheat aphids have a short life cycle, high fecundity, display phototaxis, chemotaxis and have the capacity for long distance migration. Aphid infestations on wheat leaves and ears have a clustered distribution. Aphids are typical phloem-piercing, sap-sucking pests that damage wheat not only by their feeding behavior but also by acting as a vector of the barley yellow dwarf virus （BYDV） which adversely affects wheat yield and grain quality. Several abiotic and biotic factors, such host plant resistance, natural enemies, weather factors, and agri-ecosystem engineering, have some impact on wheat aphids. Based on current understanding of wheat aphid biology, ecology and physiology, a set of techniques for the field survey, monitoring and control of aphid populations on wheat crops is described which provides a foundation for the monitoring and integrated management of wheat aphids in China.
