Identification of trail pheromone compounds from the labial glands of the stingless bee Geotrigona mombuca
(BIRKHAUSER VERLAG AG, 2009)
Foragers of several species of stingless bees deposit pheromone spots in the vegetation to guide recruited nestmates to a rich food source. Recent studies have shown that Trigona and Scaptotrigona workers secrete these ...
Búsqueda de alimento y marcación de trillo por larvas de Brassolis sophorae (Lepidoptera: Nymphalidae) en condiciones naturales

Wind disrupts trail pheromone communication in the leaf-cutting ant Acromyrmex lobicornis
(Elsevier, 2022-10)
Although wind is a ubiquitous component of ecological systems and might affect pheromone communication, its effects have not been studied in depth. To test whether wind impacts trail pheromone behaviour, we studied the ...
Meteor trails track upper atmospheric winds
(American Institute of Physics, 2009-06-01)
Meers Oppenheim and his colleagues from Boston University, Peru's Jicamarca Radio Observatory (JRO), and Los Alamos National Laboratory now offer an alternative approach that has its origins in another 50-year-old technique. ...
Hierarchical establishment of information sources during foraging decision-making process involving Acromyrmex subterraneus (Forel, 1893) (Hymenoptera, Formicidae)
(2018-01-01)
During foraging, worker ants are known for making use of many information sources to guide themselves in external environments, especially individual (memory) and social (trail pheromone) information. Both kinds of information ...
Plant odors trigger clearing behavior in foraging trails: do they represent olfactory obstacles?
(Elsevier Science, 2019-12)
Foraging trails of leaf-cutting ants may be exposed to plant material that interferes with foragers’ flux either by physically blocking it or due to secondary metabolites which affect insect behavior. We hypothesized that ...
Avoiding traffic jams: Hitchhiking behavior as a strategy to reduce ant workers’ traffic on the foraging trail
(2018-12-01)
During foraging, thousands of leaf-cutting ant workers travel along high traffic foraging trails which, when narrow, reduce the leaf delivery rate due to the reduction in workers’ travel-speed. On the other hand, high ...
Educação ambiental: alternativa para a conservação da trilha ecológica da UTFPR, DV
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilLicenciatura em Ciências BiológicasUTFPR, 2015-12-01)
The use of trails as environment subject to visitation, enabling the dissemination of information about each ecosystem has increased in recent years. The present study aimed to develop educational activities aimed at ...
Sinalização e itens de segurança para melhoria da trilha ecológica da Universidade Tecnológica Federal do Paraná Câmpus Dois Vizinhos
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilEngenharia FlorestalUTFPR, 2022-06-08)
Ecological trails are spaces and geographical paths of great historical, cultural and environmental importance. However, studies that cover adequate planning in relation to the construction of these trails are scarce, ...
Estimated losses in soybean (Glycine max (L.) Merril) harvest according to the speed and rotation of the trail system
(2021-01-01)
The soybean crop (Glycine max. (L.) Merril) shows strong participation in the Brazilian economy. Therefore, the aim of the present study was to quantify the losses in the cutting and feeding platform and in the trail system ...
