3‐Alkyl‐2‐Methoxypyrazines: Overview of Their Occurrence, Biosynthesis and Distribution in Edible Plants

ChemBioChem, Volume 24, Issue 19, October 4, 2023., 2023
Pyrazines are ubiquitous in nature and biosynthesized by microorganisms, insects, and plants. Especially 3‐alkyl‐2‐methoxypyrazines (MPs) play a key role as important aroma compounds in foods. Recently, in vivo feeding experiments with stable isotope labeled compounds revealed l‐leucine and l‐serine as important precursors for IBMP. This discovery gave

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.

POPULATION GENETICS OF Atta sexdens rubropilosa (HYMENOPTERA: FORMICIDAE)

Acta Biológica Colombiana, 2013
The genetic variability of Atta sexdens rubropilosa leaf-cutting ants collected from five brazilian localities was evaluated with PCR-RAPD technique. We used 15 primers producing 148 fragments of which 123 (83,11 %) contained polymorphisms. The estimated Shannon index was 0.3836 ± 0.2335 showing that these ants possess high genetic diversity.

Large deformation diffeomorphic mapping of 3D shape variation reveals two distinct mandible and head capsule morphs in Atta vollenweideri leaf-cutter worker ants. [PDF]

Ecol Evol
Atta vollenweideri leaf‐cutter ant workers vary continously in size across more than two orders of magnitude in body mass. We investigated whether size‐variation correlates with shape variation by analysing the 3D morphology of mandibles and head capsules.

Phylogenomic reconstruction reveals new insights into the evolution and biogeography of Atta leaf‐cutting ants (Hymenoptera: Formicidae)

Systematic Entomology, Volume 47, Issue 1, Page 13-35, January 2022., 2022
We employ phylogenomic markers (UCEs) to reconstruct the most extensively sampled phylogeny to date for the ecologically dominant leaf‐cutting ant genus Atta, the major herbivore of the New World tropics. The ancestor of Atta arose 8.5 Ma in the North/Central America + NW South America range, and its descendant species rapidly radiated into Neotropical

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.

Spatio-temporal permanence and plasticity of foraging trails in young and mature leaf-cutting ant colonies (Atta spp.) [PDF]

, 2005
The distribution and formation of foraging trails have largely been neglected as factors explaining harvesting patterns of leaf-cutting ants.We applied fractal analysis, circular, and conventional statistics to published and newly recorded trailmaps of ...
