Effects of cycloheximide on the mortality of Atta sexdens leaf-cutting worker ants

A Volatile Semiochemical Released by the Fungus Garden of Leaf-Cutting Ants

“…The major flaw in their study is that they did not identify any volatile compounds from unhealthy or dead fungi because of the effect of cycloheximide. At high concentrations, as used by Ridley et al (1996), cycloheximide causes the death of workers and the fungus garden (Sousa et al 2017(Sousa et al , 2018. Foraging behavior is probably affected by the toxicity of cycloheximide to workers and the fungus garden, and is not a behavioral response to the volatile semiochemical.…”

An organic bait based on Palicourea marcgravii (Rubiaceae) and Tephrosia candida (Fabaceae) does not control nests of Atta laevigata (Hymenoptera: Formicidae) in eucalyptus plantations

“…The effectiveness of sulfluramid baits of this same brand was 86.6% in the control of A. sexdens in eucalyptus plantations (Zanetti et al, 2004). Sulfluramid baits controlled 75% of A. laevigata nests, 86 days after its application in eucalyptus plantations (Zanetti et al, 2008) and 91.14% in the laboratory (Sousa et al, 2018). The action of sulfluramid, unlike fipronil, is slower at various concentrations, being very effective in controlling several species of leaf-cutting ants (Nagamoto et al, 2004).…”
