Fat-Soluble Substance Flow During Symbiotic Fungus Cultivation by Leaf-Cutter Ants
(Entomological Soc Brasil, 2019-11-07)
Leaf-cutter ants perform a series of specialized behaviors in preparing plant substrates for their symbiotic fungus. This process may be related to contamination of workers by substances such as insecticides, leading us ...
Do Atta sexdens rubropilosa workers prepare leaves and bait pellets in similar ways to their symbiotic fungus?
(Univ Estadual Feira Santana, 2015-12-01)
Leaf-cutting ants rely on the obligate symbiosis with a fungus, Leucoagaricus gongylophorus, on which they feed. This fungus garden is maintained preferentially with green leaves in combination with other tissues of plant ...

Allogrooming, self-grooming, and touching behavior: Contamination routes of leaf-cutting ant workers using a fat-soluble tracer dye
(2017-06-09)
The aim of this study was to determine whether worker self-grooming, allogrooming, and direct contact promotes the dispersal of substances among members of the colony. For this purpose, a tracer (Sudan III dye) was applied ...
Contamination Route of Leaf-Cutting Worker Ants Analyzed Through a Fat-Soluble Tracer Dye in Toxic Bait
(Entomological Soc Brasil, 2019-04-01)
Our study seeks to discover contamination routes of leaf-cutting worker ants during chemical control by formicide baits. To do so, toxic baits containing fat-soluble tracer dye were provided to colonies of three subspecies ...

Occurrence of non-O157 shiga toxin-encoding Escherichia coli in artisanal mozzarella cheese in Brazil: Risk factor associated with food workers
(2017-01-01)
Mozzarella cheese is considered a safe food due to the high temperature treatment used in the traditional process of stretching into hot water; however, a post-process contamination during the cheese manufacture or during ...
Occupational airborne contamination in South Brazil: 2. Oxidative stress detected in the blood of workers of incineration of hospital residues
(SPRINGER, 2009)
One of the most useful methods for elimination of solid residues of health services (SRHS) is incineration. However, it also provokes the emission of several hazardous air pollutants such as heavy metals, furans and dioxins, ...
Contamination routes and mortality of the leaf-cutting ant Atta sexdens (Hymenoptera: Formicidae) by the insecticides fipronil and sulfluramid through social interactions
(2021-01-01)
BACKGROUND: Leaf-cutting ants (LCAs) of the genera Atta and Acromyrmex (Hymenoptera: Formicidae) are important pests of forest plantations, agriculture and livestock. Toxic baits containing the active ingredients fipronil ...
