Spores of Beauveria bassiana and Trichoderma lignorum as a bioinsecticide for the control of Atta cephalotes [PDF]
Biological Research, 2019 Background The leafcutter ant (Atta cephalotes) is associated with losses in the agricultural sector, due to its defoliating activity; for its control, biological, mechanical and chemical methods have been developed, the latter associated with adverse ...

Effect of Tithonia diversifolia Mulch on Atta cephalotes (Hymenoptera: Formicidae) Nests [PDF]
Journal of Insect Science, 2015 Recent studies have shown an insecticidal effect of Tithonia diversifolia (Hemsl.) Gray (Asterales: Asteraceae) foliage on workers of Atta cephalotes L. and inhibitory effects of this plant on the growth of the symbiotic fungus Leucoagaricus gongylophorus (A. Müler) Singer. To evaluate the potential of T.

Microbial symbionts are shared between ants and their associated beetles
Environmental Microbiology, Volume 25, Issue 12, Page 3466-3483, December 2023., 2023 The colonies of army ants (Formicidae: Dorylinae) are inhabited by hundreds of closely associated insect species (myrmecophiles). Here, we asked about the similarities in microbial community composition between ants and 13 species of myrmecophile beetles.

Three cuticular amides in the tripartite symbiosis of leafcutter ants
Archives of Insect Biochemistry and Physiology, Volume 114, Issue 2, Page 1-13, October 2023., 2023 The heatmap points out three alkyl amides specific for leafcutter ants covered with symbiotic bacteria. These findings indicate an interspecific function of the described compounds within the ant−bacteria relationship. Abstract Cuticular hydrocarbons (CHCs) play various roles in insects' chemical ecology. As leafcutter ants live in a specific symbiosis

Ecology and Evolution, Volume 13, Issue 10, October 2023., 2023 We examine the predictability of gene family size changes in the pine tree specialist Neodiprion lecontei. Overall, our results are consistent with predictable gene family expansions and contractions in response to novel selection pressures. Abstract A central goal in evolutionary biology is to determine the predictability of adaptive genetic changes ...

Mechanical demands of bite in plane head shapes of ant (Hymenoptera: Formicidae) workers
Ecology and Evolution, Volume 13, Issue 6, June 2023., 2023 To assess the role of head shape in stress patterns of Pheidole workers, we solve a set of finite element analyses while exploring variation in Pheidole worker head morphospace. Our results demonstrate that head shapes of majors show signs of optimization to deal with stronger bites given that stresses dissipate more evenly along the head than in ...

Composting to control the leaf-cutting ant atta cephalotes l. (hymenoptera: formicidae)
Revista de Ciencias, 2012 Las hormigas cortadoras de hojas, Atta y Acromyrmex, son los herbívoros más importantes en los trópicos. En este estudio se comparan los efectos de dos métodos no químicos sobre la sobrevivencia y actividad de nidos de Atta cephalotes (Formicidae ...

Forager Polymorphism and Foraging Ecology in the Leaf-Cutting Ant, Atta colombica
Psyche: A Journal of Entomology, 1995 I compare forager size and foraging selectivity of the leaf-cutting ant Atta colombica and that of its close relative Atta cephalotes. In both species, larger foragers cut fragments of greater mass and area, and at vegetation sources of greater specific ...

Atta cephalotes (Hymenoptera: Myrmicinae) is colonizing urban areas in Cali, Colombia
Urban Ecosystems, 2023 Abstract Numerous studies have examined the effect of invasive species on biodiversity in urban environments, however, few of them have investigated the role of native species while turning into invasive pests. In Colombia, Atta cephalotes , a native leaf-cutting ant (LCA ...
