采用黄板诱集法研究不同季节、不同株高类型蔬菜地内拉美斑潜蝇成虫的飞翔特性。结果表明，在矮生蔬菜地内，拉美斑潜蝇成虫主要集中在近地面0.2-1.0m处；在攀缘蔬菜地内，主要集中在近地面0.5－3．0m处。
The yellow-leaf trapping method was used to study the flight characteristics of adults with different plant height and vegetable type in different seasons. The results showed that in the dwarf vegetable fields, adults of L. occidentalis mainly concentrated in the range of 0.2-1.0 m near the ground; in the climbing vegetable area, they mainly concentrated in the area of 0.5-3.0 m near the ground.
