Leaf cutting-ants: Control methods and sustainability

open access: yes, 2022
The fungus-growing ants belong to the genus Atta and Acromyrmex and individuals are causing serious damage to various types of plantations due to the habit of cutting leaves and shoots of economic importance for use in cultivating the garden symbiotic fungus colonies, causing serious damage. The ants attack is harmful at any stage of the cycle, but the

Height and phytotelm size affect the invertebrate communities of epiphytic bromeliads in the Amazon rainforest

open access: yesEcological Entomology, EarlyView.
The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

From leaves to defenders: How the amount and dispersion of leaf damage affect extrafloral nectar production and ant‐mediated protection in wild cotton

open access: yesEcological Entomology, EarlyView.
Extrafloral nectar mediates interactions among plants, ants and herbivores; its contingency on damage amount and within‐plant uniformity is poorly understood. Here, we explore these factors in wild cotton (Gossypium hirsutum). Herbivory amount drove increases in extrafloral nectar induction per nectary, whereas within‐plant variability in damage ...

Factors influencing microbial activity in dumps leaf cutter ants [PDF]

open access: yes, 2014
La descomposición de la materia orgánica que realizan los microorganismos del suelo es vital para el funcionamiento de los ecosistemas terrestres. Nosotros usamos a los basureros de las hormigas cortadoras de hojas como un sistema modelo para determinar ...

An Easy Method to Sample Headspace Pheromones in the Field

open access: yesEthology, EarlyView.
Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.

Taxonomic, phylogenetic and functional diversity patterns of Saturniidae moth communities along a tropical forest recovery gradient in Ecuador

open access: yesInsect Conservation and Diversity, EarlyView.
Diverse Saturniidae moth communities are found in naturally recovering tropical forests in Ecuador. Community composition showed a gradual turnover with strongest differences between old‐growth forest and active agriculture, but only weak differences in taxonomic, phylogenetic and functional diversity. While our results suggest that Saturniidae are not

Diversity, prevalence and virulence of fungal entomopathogens in colonies of the ant Formica selysi [PDF]

open access: yes, 2018
The richness of the parasitic community associated with social insect colonies has rarely been investigated. Moreover, understanding how hosts and pathogens interact in nature is important to interpret results from laboratory experiments.

Collaborative platooning and routing for mixed fleets of electric automated vehicles and conventional trucks

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The application of automated ground vehicles (AGVs) is well‐established in closed environments such as port terminals, while their operation in open areas remains challenging. In this work, we set out to overcome this limitation by introducing platooning as a transfer mode in heterogeneous vehicle networks.

Pathogenicity of Bacillus thuringiensis isolated from two species of Acromyrmex (Hymenoptera, Formicidae)

open access: yesBrazilian Journal of Biology
The control of Acromyrmex leaf-cutting ants is necessary due to the severe damage they cause to diverse crops. A possibility was to control them using the bacterium Bacillus thuringiensis (Bt) that characteristically produces insecticidal crystal ...
