Three cuticular amides in the tripartite symbiosis of leafcutter ants

Archives of Insect Biochemistry and Physiology, Volume 114, Issue 2, Page 1-13, October 2023., 2023
The heatmap points out three alkyl amides specific for leafcutter ants covered with symbiotic bacteria. These findings indicate an interspecific function of the described compounds within the ant−bacteria relationship. Abstract Cuticular hydrocarbons (CHCs) play various roles in insects' chemical ecology. As leafcutter ants live in a specific symbiosis

Weathering the hunt: The role of barometric pressure in predator insects' foraging behaviour

Ecology and Evolution, Volume 13, Issue 8, August 2023., 2023
Despite the essential role of barometric pressure, its influence on insects remains poorly understood, particularly in predator insects. Our study showed that three predator species from distinct orders, with varying morphological, physiological, ecological and biological characteristics, modify their foraging behaviour in response to barometric ...

Da Vinci's yeast: Blastobotrys davincii f.a., sp. nov

Yeast, Volume 40, Issue 1, Page 7-31, January 2023., 2023
Several surveys from around the world reported the same yeast species from a wide range of substrates, most notably from the iconic self‐portrait of Leonardo da Vinci. None of these studiesidentified their strains, clones, or OTUs as Blastobotrys. Here we describe this as a new species and name it Blastobotrys davincii.

Revisiting the hymenopteran diploid male vortex: a review of avoidance mechanisms and incidence

Entomologia Experimentalis et Applicata, Volume 170, Issue 12, Page 1010-1031, December 2022., 2022
The Hymenoptera (bees, ants, wasps, and sawflies) have haploid males and diploid females. According to the diploid male vortex (DMV) theory, inbreeding increases sterile diploid male production and extinction risk for many species. We reviewed DMV incidence and avoidance.

Phorid Flies Parasitizing Leaf-Cutting Ants: Their Occurrence, Parasitism Rates, Biology and the First Account of Multiparasitism

Sociobiology, 2016
The leaf-cutting ants Atta sexdens (Linnaeus) and Atta laevigata (Smith) were parasitized by the following phorid flies: Apocephalus attophilus Borgmeier, Apocephalus vicosae Disney, Myrmosicarius grandicornis Borgmeier and species of Eibesfeldtphora ...

BIOLOGICAL CONTROL IN LEAF-CUTTING ANTS, Atta sexdens (HYMENOPTERA: FORMICIDAE), USING PATHOGENIC FUNGI

Revista Árvore, 2021
Chemical control using toxic baits containing the active ingredient sulfluramid at 0.3% (w/w) is the main method for controlling leaf-cutting ants of the genera Atta and Acromyrmex.

Shifts in Chromosome Evolution Rates Shape the Karyotype Patterns of Leafcutting Ants. [PDF]

Ecol Evol
Modern phylogenetic methods were used to explore how chromosome number and other karyotypic traits vary across species. The focus was on testing whether karyotypic traits follow a Brownian motion model (indicating neutral changes) or are influenced by phylogenetic constraints.This research elucidates the mechanisms underlying chromosomal evolution and ...

Age Polyethism in Atta sexdens (Linnaeus) (Hymenoptera: Formicidae)

Sociobiology, 2020
This study aimed to verify age polyethism occurrence in medium-sized (cephalic capsule = 2.3 ± 0.21 mm) and small-sized (cc = 1.4 ± 0.10 mm) workers from Atta sexdens (Linnaeus) colonies. Four laboratory colonies were used, and they were maintained at 25 ± 2 °C, with 75 ± 3% relative humidity and a 12-hour photoperiod.

Bioactivity of Asclepias curassavica, Equisetum spp. and Rosmarinus officinalis Extracts Against Leaf-Cutting Ants

Sociobiology, 2019
Chemical control of leaf-cutting ants is widely used, but alternative control with toxic plant extracts is promising. Substances with insecticidal potential extracted from plants have numerous ecological advantages.
