Attack density negatively affects reproductive success but not fecundity or offspring body size in a bark beetle

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 1, Page 76-81, February 2026.
Neither gallery length nor eggs per female varied significantly with attack density, suggesting P. proximus adults disregard galleries constructed by conspecifics and continue to lay eggs irrespective of attack density. Number of adult offspring per female decreased significantly as attack density increased, indicating that intraspecific competition ...

The role of tropical forest fragment vegetation in maintaining arthropod diversity and spillover to adjacent sugarcane fields O papel da vegetação de fragmentos de floresta tropical na manutenção da diversidade de artrópodes e na sua disseminação para campos de cana‐de‐açúcar adjacentes

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 1, Page 82-93, February 2026.
Tree diversity increases arthropod richness and the abundance of beneficial arthropod groups within Atlantic Forest fragments. Higher insect richness in forest fragments is associated with greater richness in adjacent sugarcane fields, and both habitats share insect families, suggesting spillover.
