Arthropods obtained from the Amazonian tree species "Cupiuba" (Goupia glabra) by repeated canopy fogging with natural Pyrethrum [PDF]

open access: yesActa Amazonica, 1998
Two canopies of a widely distributed Amazonian tree species, Goupia glabra Aubl. (Celastraceae, height 38 and 45m) were fogged several times with 1% natural pyrethrum during the rainy and dry seasons (1991-1994) in the Adolpho Ducke Forest Reserve near ...

Strong diel variation in the activity of insect taxa sampled by Malaise traps

open access: yesEcological Entomology, Volume 51, Issue 3, Page 533-546, June 2026.
Malaise traps sampled different communities during mornings (06:00–12:00), afternoons (12:00–16:00), evenings (18:00–22:00), and nights (22:00–06:00), highlighting the difference in diel rhythm between taxa. The highest diversity and abundance of insects were found during afternoons, the lowest diversity during night, and the lowest abundance during ...

The value of regeneration for insect fauna associated with leaf litter in the Brazilian savanna: A comparative study of biomass and trophic structure

open access: yesAnnals of Applied Biology, Volume 188, Issue 3, Page 875-888, May 2026.
This study demonstrates the ecological value of natural regeneration in the Brazilian Cerrado by analysing the biomass, richness and trophic structure of leaf litter insects across pasture (P), regenerating (R) and native (N) areas. We found that R areas supported insect communities more similar to N habitats than to Ps, with higher richness, greater ...

Forest type influence on Heliconia‐dipteran interaction networks

open access: yesInsect Conservation and Diversity, Volume 19, Issue 3, Page 660-674, May 2026.
Responses to forest type depended on the developmental stage of dipterans. Bract traits and forest type influenced larval abundance, but forest type had no impact on adult alpha and beta diversity. Heliconia‐dipteran interaction networks showed a nested pattern for both forest types.

Plant‐mediated interactions between specialist insect herbivores of Melaleuca quinquenervia: Implications for management of invasive populations

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
The gall forming herbivores Lophodiplosis trifida and L. indentata reduced the growth of M. quinquenervia, with L. trifida exerting a stronger suppressive effect than L. indentata. The addition of L. trifida enhanced the negative impact of L. indentata on plant growth, whereas the presence of L. indentata did not affect the impacts of L. trifida.

Phage Display Derived Antibodies Against Antimicrobial Peptide FsPDF2 Reveal Stress Response in European Beech

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 1950-1965, April 2026.
ABSTRACT Plant defensins (PDFs) are cysteine‐rich antimicrobial peptides (AMPs) that are important components of plant immunity. They occur constitutively in various plant tissues but are also upregulated upon stress. Therefore, these molecules are of great interest as markers for the diagnosis of early forest stress response in plants at the molecular

Gall responses to drying habitats: Insights from the community of galling herbivores associated with the superhost Caryocar brasiliense Cambess. (Caryocaraceae)

open access: yesPlant Biology, Volume 28, Issue 3, Page 924-938, April 2026.
Drying processes in the Brazilian palm swamps or Veredas, impact the gall community in adjacent vegetation by reducing the abundance of more sensitive galls, while more resilient galls acclimate to increased dryness by developing thicker protective tissues. Abstract Galls are new plant organs formed in response to the stimuli of gall‐inducing organisms,
