Oviposition Activity of an Invasive Fruit Fly Species at Different Densities in Laboratory

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 1, Page 45-52, January 2026.
Bactrocera carambolae Drew & Hancock, 1994 (Diptera: Tephritidae) is a major fruit fly pest affecting Brazil's international fruit trade due to phytosanitary restrictions. Although currently restricted to northern Brazil, little is known about its oviposition behavior. In this study, we investigated the daily oviposition pattern of B.

Selection for resistance to cacao Moniliasis assisted by molecular markers : S04P06 [PDF]

open access: yes, 2013
The basidiomycete Moniliophthora rorer, the etiological agent of Moniliasis, reaches cacao plantations (Theobroma cacao) in Central and South Americas, but its occurrence is still not registered in Brazil .

Structural and Functional Co‐Adaptation of Plants of the Genus Lysimachia L. (Primulaceae) and Pollinating Insects of the Genus Macropis Panzer (Hymenoptera, Melittidae)

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
The co‐adaptation of bees from the genus Macropis and Lysimachia plants has been studied in detail. Research shows that bees collect not just pure liquid oil from flower petals but tear off trichome heads filled with oil, transferring them to their nests.

Similar genetic mechanisms underlie the parallel evolution of floral phenotypes. [PDF]

open access: yesPLoS ONE, 2012
The repeated origin of similar phenotypes is invaluable for studying the underlying genetics of adaptive traits; molecular evidence, however, is lacking for most examples of such similarity.

Development of EST derived-SSRs of Theobroma grandiflorum for molecular breeding : S04P05 [PDF]

open access: yes, 2013
Simple sequence repeats (SSRs) markers are widely used in breeding programs, and SSRs associated to expressed sequence tags (ESTs) could be quite efficient in the selection of genotypes of interest.

Explosive Radiation of Malpighiales Supports a Mid-Cretaceous Origin of Modern Tropical Rain Forests [PDF]

open access: yes, 2005
Fossil data have been interpreted as indicating that Late Cretaceous tropical forests were open and dry adapted and that modern closed-canopy rain forest did not originate until after the Cretaceous-Tertiary (K/T) boundary.

Complex interactions in ant–plant mutualisms: The role of multiple ant food resources in mediating plant defence, pollination and fitness in a tropical shrub

open access: yesEcological Entomology, Volume 50, Issue 6, Page 1137-1147, December 2025.
Our results show that ants reduced leaf herbivory on plants offering both EFN and trophobiotic insects. Although ants did not directly affect pollinator behaviour, leaf herbivory in plants hosting treehoppers indirectly influenced pollination by reducing both visit duration and frequency.

A comprehensive guide to the Argentinian case-bearer beetle fauna (Coleoptera: Chrysomelidae: Camptosomata) [PDF]

open access: yes, 2017
Knowledge of Argentinian Camptosomata has largely remained static for the last 60 years since the last publication by Francisco de Asis Monrós in the 1950’s.
