中文摘要：
为明确黄色粘板对小麦蚜虫及其天敌的诱集作用，2010和2011年，在中国科学院河北栾城县农业生态系统试验站，通过在小麦田间悬挂黄板，对其诱杀小麦蚜虫效果及对小麦蚜虫天敌的影响进行了调查统计分析。结果表明，当地悬挂的黄板可以诱杀7目30余种昆虫，优势种是蝇类，
而非小麦蚜虫。悬挂区内不进行化学防治时，黄板诱杀蚜虫数量与其相应百株虫量之间呈显著的线性相关，进行化学防治时，两者之间的线性相关不显著。黄板可以诱杀多种小麦蚜虫的天敌，灌浆期前后，黄板诱集到的益害比都大于1，最高可达45.50。在综合考虑黄板对小麦蚜虫
及其天敌的诱杀作用，以及可能影响黄板诱集效果的气象条件后，初步结论是在河北栾城及周边地区，黄板可用于早期迁入小麦有翅蚜的监测
，但不适合防治小麦穗期的蚜虫。
英文摘要：
In order to estimate their trapping effect on wheat aphids and their natural enemies, yellow sticky card traps were setup in
wheat fields at the Luancheng agroecosystem station of the Chinese Academy of Science in Hebei Province in 2010 and 2011. More than 30 species of insect from 7 orders were trapped; the dominant species captured was a fly species rather than wheat aphids. The effectiveness of yellow sticky card traps for trapping wheat aphids was significantly correlated to the
population size per 100 tillers when application of chemical pesticides in sampling area were under control and was not significant without such control. Yellow sticky card traps can kill a large number of natural enemies of the wheat aphid. The ratio of trapped natural enemies and pest insects before and after the grouting stage were both greater than 1, with the maximum ratio up to 45.50. In view of the effectiveness of yellow sticky card traps in catching wheat aphids and their natural enemies and the potential influence of weather conditions and other factors, these traps are not recommended for controlling wheat aphids but can be used as a tool for monitoring these pests.
