2012年7月对广州市九龙镇柑橘园内红火蚁的发生密度进行调查。调查结果显示,柑橘园内的平均蚁巢密度每100m2为7个,红火蚁疫情处于中度危害阶段;地上诱集到红火蚁的诱饵占56.41%,柑橘树上诱集到红火蚁的诱饵占25.96%,红火蚁在柑橘树上的活动程度低于地面。通过调查不仅对准确掌握疫情、科学制定防治策略有实际意义,还为评估红火蚁对柑橘生态系统的影响提供了基础数据。
In July 2012, the occurrence density of red imported fire ant in citrus orchards in Jiulong Town, Guangzhou City was investigated. The survey results showed that the average nest density in citrus orchard was 7 per 100m 2, and the epidemic situation of R. sinensis was moderately harmful. The bait trapped on R. tern (56.41%) and the trap on T. citri 25.96%. The activity of SIFs on citrus trees was lower than that on the ground. Through investigation, it not only has an accurate grasp of the epidemic situation, but also has practical significance in formulating the scientific prevention and cure strategy. It also provides the basic data for assessing the impact of the red imported fire ant on the citrus ecosystem.
