Managing pests by increasing predators through late termination of cover crops
Pest 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 ...

Mathematical modeling on obligate mutualism: Interactions between leaf-cutter ants and their fungus garden [PDF]
Journal of Theoretical Biology, 2011 We propose a simple mathematical model by applying Michaelis-Menton equations of enzyme kinetics to study the mutualistic interaction between the leaf cutter ant and its fungus garden at the early stage of colony expansion. We derive the sufficient conditions on the extinction and coexistence of these two species.

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

Urban physiology: city ants possess high heat tolerance.
PLoS ONE, 2007 Urbanization has caused regional increases in temperature that exceed those measured on a global scale, leading to urban heat islands as much as 12 degrees C hotter than their surroundings.

Major changes in microbial diversity and community composition across gut sections of a juvenile Panchlora cockroach. [PDF]
PLoS ONE, 2017 Investigations of gut microbiomes have shed light on the diversity and genetic content of these communities, and helped shape our understanding of how host-associated microorganisms influence host physiology, behavior, and health.

The continuing significance of chiral agrochemicals
Pest 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.

Cassava leaf methanolic extract as an alternative to control of fall armyworm and leaf cutter ants
Semina: Ciências Agrárias, 2013 The objective of this study was to characterize phenolic compounds and evaluate the effect, under laboratory conditions, of the cassava leaf powder methanol extract on the development of fall armyworm Spodoptera frugiperda and of leaf-cutting ant Atta ...

The predatory behavior of ants: an impressive panoply of morphological adaptations
Insect Science, EarlyView.This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Ecología Austral, 1994 The diet of the leaf-cutter ant Acromyrmex striatus was used as indirect evidence for potential antiherbivore activity by the nectivorous ant Camponotus blandus and by chemical and mechanical plant defenses.
