摘要: 利用黄色粘虫板调查了田间麦红吸浆虫成虫种群密度在垂直方向上的差异以及性比的变化。结果表明:麦红吸浆虫成虫主要在地面至40 cm左右的麦株间活动,种群密度随高度的升高而逐渐降低;不同羽化时期麦红吸浆虫的性比变化较大,羽化初期,雄虫的比例较高,末期则几乎全部为雌虫;在垂直方向上随着高度的增加雌虫的比例逐渐升高;天气因素对其田间扩散飞行具有重要影响。

Abstract: By using yellow sticky traps, an investigation was made on the population density of adult Sitodiplosis mosellana in vertical direction and the sex ratio of the adults in a wheat field. The activities of the adult S. mosellana in the wheat field were mainly at 0-40 cm  above the ground, and the population density decreased with increasing height. The sex ratio of the adults varied widely in different eclosion periods, with a higher percentage of males in the early period but nearly 100% of females in the late period. In vertical direction, the percentage of the females increased with increasing height. Weather factors played an important role in the dispersal of adult S. mosellana.
