- 摘要:
- 对烟粉虱若虫在 223 份不同结荚习性大豆品种植株上的分布进行了调查研究 。结果表明烟粉虱若虫在夏大豆植株上的总体分布集中在中上部 ,占总数的 83. 1%, 中部与上部之间差异不显著。不同结荚习性大豆品种上烟粉虱若虫的分布存在明显差异 。有限结荚习性品种主要分布在上部,上 4 叶烟粉虱数占单株烟粉虱总数的 57. 7%;无限结荚习性品种主要分布在中上部 ,第 11 叶至第 16 叶上烟粉虱数占单株烟粉虱总数的 53. 1%;亚有限结荚习性品种中 5 叶烟粉虱数占单株烟粉虱总数的 39. 6%, 上 5 叶烟粉虱数占单株烟粉虱总数的 41. 4%。由此可以看出 ,化学防治烟粉虱的重点部位是大豆植株的中上部叶片。
- Abstract:
- T he distribution of whitefly nymph on the plants of 223 summer soybean varieties was in vesti-galed. The result showed that 83. 1%of whitefly nymphs were present on top and middle leaves and therewas no marked difference between middle and top leaves;significant difference was observed on the distri-bution of whitefly nymphs among different podding habit soybean varieties. In determinate podding habitvarieties, 57. 7%of whitefly nymphs were present on upper 4 leaves;in indeterminate podding habit varie-ties, 53. 1%of whitefly nymphs were present on from the 11th leaves to 16th leaves;in semi-determinatepodding habit varieties , 39. 6 %and 41. 4%of whitefly nymphs were present on the 5 middle leaves and 5top leaves, respectively. The chemical control of whitefly nymphs should mainly focus on the top and mid-dle leaves according to the whitefly nymph distribution.
