带土园艺植物传播红火蚁的风险调查

调查了广东广州、深圳40余个苗木花卉场74种带土园艺植物上红火蚁Solenopsis invicta Buren发生情况。调查结果表明,桉树苗、海枣、垂叶榕、黄金香柳、小叶榕、狗尾草、罗汉松等17种植物上红火蚁发生比率超过1%,是高风险带土植物。不同生产环境、不同栽培方式中盆/钵/袋栽红火蚁发生高于地面栽培方式,露天置于砂土、泥土、碎石上红火蚁发生风险较高,置于水泥地上的风险较低。提出了降低带土园艺植物传播红火蚁的管理措施。

Infestation probability of the red imported fire ant, Solenopsis invicta , in nursery and stocks

Seventy six species of gardening plants with soil and cultivated medium attached from 42 horticulture farms were surveyed in Shenzhen and Guangzhou, Guangdong Province for evaluating the spreading risk of red imported fire ant, Solenopsis invicta Buren. The results showed that there was high risk for 17 species plants to transmit the red imported fire ant, and the percents of infestation were more than 1%. In different environments and cultivated types, the infestation percents of red imported fire ant were different, and the percent of infestation were obviously high in plants cultivated in the pots, bowls and bags in the open air. Some management measures to reducing the infestation of red imported fire ant in gardening plants were also discussed.
