- Leaf-cutting ants of the genus Atta (Myrmicinae: Attini) are the main forest pests in Brazil, due to their economic damage, social complexity and geographical distribution. Chemical control with baits is the most viable and successful method to control these insects; and products with low environmental impact have been researched.
- The objective of this study was to evaluate the mortality of Atta laevigata (Hymenoptera: Formicidae) nests treated with Bioisca® bait, in different dosages, in eucalyptus plantations compared with those treated with sulfluramid and fipronil baits.
- Seven treatments were used: Bioisca® (Palicourea marcgravii (Rubiaceae) + Tephrosia candida (Fabaceae)), with 5, 10, 15 and 20 g; Blitz® (fipronil), Atta Mex-S® (sulfluramid) baits with 6 g/m2 of ant nest loose soil and the control, without ant baits.
- It took 7 days for the first colony to have its activity stopped using the Blitz® treatment. It happened only at 30 days when treated with Bioisca® and Atta-Mex-S® .
- The mortality of nests treated with Bioisca® was very low with only one controlled out of 20 that received this bait. Bioisca® does not control the nests of A. laevigata in eucalyptus plantations.

基于 Palicourea marcgravii（茜草科）和 Tephrosia candida（豆科）的有机诱饵不能控制桉树种植园中的 Atta laevigata（膜翅目：蚁科）的巢穴
- 由于其经济损失、社会复杂性和地理分布，阿塔属（Myrmicinae：Attini）的切叶蚁是巴西的主要森林害虫。用诱饵进行化学控制是控制这些昆虫最可行和最成功的方法。并且研究了对环境影响低的产品。
- 本研究的目的是评估在桉树种植园中用不同剂量的 Bioisca® 诱饵处理的Atta laevigata（膜翅目：蚁科）巢穴与用氟虫胺和氟虫腈诱饵处理的巢穴的死亡率。
- 使用了七种处理：Bioisca®（Palicourea marcgravii（茜草科）+ 念珠菌（豆科）），分别为 5、10、15和 20 克；Blitz®（氟虫腈）、Atta Mex-S®（氟虫胺）诱饵，含 6 g/m 2的蚂蚁窝松土和对照，不含蚂蚁诱饵。
- 使用 Blitz® 处理后，第一个菌落需要 7 天才能停止活动。它仅在使用 Bioisca® 和 Atta-Mex-S® 处理 30 天时发生。
- 用 Bioisca® 处理的巢穴的死亡率非常低，接受这种诱饵的 20 只鸟巢中只有 1 只受到控制。Bioisca® 不控制桉树种植园中A. laevigata的巢穴。
