Colonization pattern of Cecropia by Azteca ants: Influence of plant ontogeny, environment and host plant choice by queens

open access: yes, 2022
Several plant species of the large Neotropical genus Cecropia acts as a host plant for ants, especially those of the genus Azteca. Although literature has reported that the Azteca queens found colonies by perforating the prostoma to establish their nests inside the Cecropia trunks (domatia), little is known about which host plant parameters (e.g ...

Phylogenetic insights into Dyopsinae (Lepidoptera, Noctuidae): Resolving the systematic position of Thiacidinae

open access: yesSystematic Entomology, Volume 51, Issue 2, April‐June 2026.
In this study, a new phylogenetic study reclassifies the moth subfamilies Dyopsinae and Thiacidinae. For the first time, Thiacidas postica—the type species of Thiacidinae—was sequenced and shown to belong within Dyopsinae, in the Ceroctena clade. As a result, Thiacidinae is reinstated as the tribe Thiacidini (stat. nov.) within Dyopsinae.

Insect‐Derived Bioactives for Glycemic Control and Gut Health: A Review

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
Insect‐derived bioactive compounds (e.g., peptides, polysaccharides) effectively regulate blood glucose through dual mechanisms: directly inhibiting carbohydrate‐digesting enzymes and glucose transporters, and indirectly modulating gut microbiota to enhance intestinal barrier integrity.

Patterns of Tree Species Abundance and Diversity on Urban Sidewalks in Macapá, Amapá, Brazil

open access: yesEcological Research, Volume 41, Issue 2, March 2026.
This study presents the first systematic inventory of street trees in Macapá, Northeastern Brazilian Amazon. Results reveal a dominance of exotic and fruit‐bearing species, low tree density, and a replacement of large canopy trees by smaller ones, indicating potential losses in ecosystem services and the need for more biodiversity‐focused afforestation
