Edge-induced narrowing of dietary diversity in leaf-cutting ants

open access: yes, 2010
Much of the ecological alteration faced by human-modified Neotropical forests can be assigned to edge effects, including the proliferation of some voracious herbivores such as leaf-cutting ants.

Managing pests by increasing predators through late termination of cover crops

open access: yesPest Management Science, EarlyView.
Adding cover crops to crop rotations can improve the sustainability and ecosystem functioning of agroecosystems. By delaying cover‐crop termination, growers can effectively increase natural enemy populations and reduce the need for chemical controls. Abstract BACKGROUND Adding cover crops to crop rotations can improve the sustainability and ecosystem ...

Remote Sensing to Detect Nests of the Leaf-Cutting Ant Atta sexdens (Hymenoptera: Formicidae) in Teak Plantations

open access: yesRemote Sensing, 2019
Leaf-cutting ants of the genus Atta are an important insect pest in forest plantations in many countries of South America. The objective of this work was to evaluate the potential for using Landsat-8 images, with medium spatial resolution and distributed

Leaf processing behavior in Atta leafcutter ants: 90% of leaf cutting takes place inside the nest, and ants select pieces that require less cutting

open access: yes, 2015
<p>Leafcutter ants cut trimmings from plants, carry them to their underground nests, and cut them into smaller pieces before inoculating them with a fungus that serves as a primary food source for the colony. Cutting is energetically costly, so the

Microbiome‐mediated chemical communication in insects: Implications for pest management

open access: yesPest Management Science, EarlyView.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Fuzzy modeling of reoccupation of a leaf-cutting ants’ trail

open access: yesTEMA (São Carlos), 2015
In this paper we model the reoccupation of a trail by leaf-cutting ants.<br />The mathematical modeling consists in studying the leaf-cutting ants’ displacement<br />towards an attraction area and their return to the nest. To carry out this research,<br />we utilized the diffusion-advection equation, where the dispersion and velocity ...

Collective action in ant control: [PDF]

open access: yes
Leaf-cutting ants (Atta. cephalotes) represents a serious problem to farmers in many parts of Latin America and accounts of ants eating up a whole cassava plot or destroying one or more fruit trees overnight are not uncommon.

Presence of Trichoderma in leaf pieces carried or rejected by workers of leaf-cutting ants

open access: yes, 2017
Recognition of endophytic Trichoderma mycoparasites by leaf-cutting ants and their potential in a Trojan-horse management strategy - Rejected leaves were considered to be those scattered by the ants above or at the side of the nest entrances.

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
