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

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 ...

New state record of Lopesia similis Maia (Insecta, Diptera, Cecidomyiidae) [PDF]
Lopesia similis Maia, 2004 (Insecta, Diptera, Cecidomyiidae) is recorded for the first time in the state of Mato Grosso do Sul. This species induces leaf galls on Protium heptaphyllum March (Burseraceae).

Forest type influence on Heliconia‐dipteran interaction networks
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.

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.

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

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,
