调查了海南省乐东县、东方市和昌江县腰果种植区的黄猄蚁Oecophylla smaragdina Fabricius发生情况,结果表明,3个腰果种植区均有较为丰富的黄猄蚁资源。调查发现,常年失管的腰果园黄猄蚁资源较为丰富,这些腰果园人为活动干扰少,有利于黄猄蚁的自然定殖、繁衍和扩散。黄猄蚁蚁巢在腰果树北面(3.1个/株)分布数量最多,其次为西面(2.3个/株)和东面(2.0个/株),南面(0.9个/株)蚁巢数量最少。黄猄蚁蚁巢长度和宽度、蚁巢长度和离地高度以及蚁巢宽度和离地高度均呈极显著的线性正相关关系。
The occurrence of Oecophylla smaragdina Fabricius in the cashew region of Ledong County, Dongfang City and Changjiang County in Hainan Province was investigated. The results showed that all the three cashew nuts were rich in the resources of A. citri. The survey found that perennial tube failure cashew orchard resources are plentiful, these cashew orchards interfered with human activity is less conducive to the natural colonization, reproduction and proliferation of ants. The ant nests were most distributed in the north of the cashew tree (3.1 / plant), followed by the west (2.3 / plant) and the east (2.0 plants / plant), the south (0.9 / plant) . The length and width of ant nests, ant nests length and height of ant nests, ant nests width and height from ground were extremely significant linear positive correlation.
