瑞丽市 3 种类型柠檬园地表蚂蚁群落多样性研究

为探讨覆膜对柠檬园地表蚂蚁群落的影响,于2016年4月和7月采用陷阱法对云南省瑞丽市覆膜种植和常规种植模式下3种类型柠檬园地表蚂蚁群落进行调查。结果表明,柠檬园RG采集地表蚂蚁17种276头;柠檬园RH采集地表蚂蚁22种527头;柠檬园RI采集地表蚂蚁16种273头。3种类型柠檬园间地表蚂蚁相对多度和物种丰富度均有显著差异,柠檬园RH中地表蚂蚁的相对多度和物种丰富度均显著高于柠檬园RG和柠檬园RI。3种类型柠檬园间地表蚂蚁群落结构互不相似。覆膜降低了柠檬园地表蚂蚁群落的相对多度和物种丰富度,除草剂对柠檬园地表蚂蚁的相对多度和物种丰富度无影响,但可以改变地表蚂蚁群落结构。

Diversity of ground-dwelling ant communities in lemon orchards in Ruili city

In order to explore the effects of plastic film mulching on the ground-dwelling ant communities in lemon orchards. The ground-dwelling ant communities were investigated by pitfall traps in three types of lemon orchards under plastic film mulching and conventional planting patterns in Ruili City, Yunnan Province. The result showed that: 276 ant individuals were collected in the lemon orchard RG, representing 17 species; 527 ant individuals were collected in the lemon orchard RH, representing 22 species; 273 ant individuals were collected in the lemon orchard RI, representing 16 species. There were significant differences of ground-dwelling ant relative abundance and species richness among the three types of lemon orchards, the relative abundance and species richness of ground-dwelling ants in lemon orchard RH were significantly higher than those in lemon orchard RG and lemon orchard RI. The community structure of ground-dwelling ant was not similar in 3 types of lemon orchards. Plastic film mulching decreased the relative abundance and species richness of ground-dwelling ants, Herbicides had no effect on the relative abundance and species richness of ground-dwelling ants in lemon orchard, but could change the community structure of ground-dwelling ants in Lemon orchards.
