摘要
2008-2009年在河南省洛宁县调查了小麦红吸浆虫的禾本科寄主植物,发现麦田地头的节节麦和邻近麦田的沙杨林地中的纤毛鹅观草均被小麦红吸浆虫侵染。纤毛鹅观草被侵染的水平仅次于小麦,虫穗率超过50%。节节麦、大麦、雀麦也有较低的侵染水平。纤毛鹅观草有较晚的抽穗期,抽穗期长达10 d,是小麦红吸浆虫比较合适的交替寄主。
The results of our investigation showed that the Tausch goatgrass Aegilops tauschii in the wheat field and the ciliate goosecomb Roegneria ciliaris in the adjacent grassland under the poplar woods served as hosts of the wheat midge Sitodiplosis mosellana in Luoning County, Henan Province during 2008--2009. Likewise, we found that ciliate goosecomb had a high level of infestation, while Tausch goatgrass, barley, and Japan bromegrass Bromus japonicus Thunb. had lower levels of infestation. R. ciliaris was recognized as a suitable alternative host due to its later （29th, April） and longer earing stage （10days） compared to that of wheat （16th, April and 4 days respectively）.
