Influence of forest cover and sex on wing size and shape of a spider‐hunting wasp in the Brazilian Atlantic forest

open access: yesEcological Entomology, Volume 51, Issue 1, Page 165-176, February 2026.
Forest cover significantly influences the wing shape of female Trypoxylon lactitarse. Females exhibit longer and narrower wings, linked to greater flight efficiency and dispersal. Sexual dimorphism indicates that females respond differently to ecological pressures, underscoring the role of forest cover in species persistence.

Air pollution and its multifaceted effects on insect pollinators: A review

open access: yesEcological Entomology, Volume 51, Issue 1, Page 1-17, February 2026.
Air pollution disrupts plant‐pollinator interactions by impairing floral signal transmission, altering foraging behaviour, and reducing pollinator fitness, flight efficiency, reproduction and survival, posing serious threats to ecological stability.

Evidence of separate karyotype evolutionary pathway in Euglossa orchid bees by cytogenetic analyses

open access: yesAnais da Academia Brasileira de Ciências, 2013
Euglossini are solitary bees considered important pollinators of many orchid species. Information regarding chromosome organization is available for only a small number of species in this group.

Floral Handedness in Mormodes Orchids: Revisiting Charles Darwin's Observations

open access: yesBiotropica, Volume 57, Issue 6, November 2025.
In this study, we scrutinized floral enantiostyly in Mormodes orchids, a unique trait within Orchidaceae first observed by Charles Darwin. We hypothesize how intricate column twisting drives strategic pollinarium placement onto opposite sides of the thorax of male euglossine bees, enhancing cross‐pollination.

Solitary oil‐collecting bee in cities: Habitat suitability and lack of population structuring in Centris analis

open access: yesInsect Conservation and Diversity, Volume 18, Issue 6, Page 982-996, November 2025.
Lack of genetic population structure in urban populations of Centris analis. Low morphological differentiation across four phytogeographical regions in Brazil. Monogyny‐monandry mating system in C. analis. Abstract The decline of insect populations worldwide has raised concerns about the negative impact on ecosystem services, particularly pollination ...

The magnitude of cryptic insect diversity in one tropical rainforest

open access: yesInsect Conservation and Diversity, Volume 18, Issue 6, Page 1163-1174, November 2025.
We detected 214 cryptic species out of a total of 2006 species (10.6%) examined from 22 focal insect taxa in 1500 ha tropical rainforest in Panama. The percentage of cryptic species varied greatly among assemblages (0%–19%), with half of the assemblages devoid of cryptic species and the highest proportions of cryptics in Pieridae and Formicidae ...

24 million years of pollination interaction between European linden flowers and bumble bees

open access: yesNew Phytologist, Volume 248, Issue 4, Page 2111-2127, November 2025.
Summary Pollination is the most common insect–plant mutualism, binding them in a co‐evolutionary framework. Historic evidence of this interaction can be partly inferred from time‐calibrated molecular phylogenies of plant and insect lineages or directly from fossils.

Preliminary study of insect attraction by a mixture of semiochemicals containing 1,2,4-Trimethoxybenzene in domestic citric-culture

open access: yesQuímica Nova, 2010
In this work we describe a new efficient strategy for the preparation of 1,2,4-trimethoxybenzene (3) in 56% overall yield. The compound 3 was used in a preliminary study of insect attraction by a mixture of semiochemicals called TIV, composed of indol (1)

The Large Carpenter Bees (Xylocopa, Apidae) of the Neotropical Region: Phylogenetics, Classification and Biogeography

open access: yesZoologica Scripta, Volume 54, Issue 6, Page 884-896, November 2025.
ABSTRACT The large carpenter bees of the genus Xylocopa comprise almost 400 species distributed worldwide. Their large body and ability to build nests through woodworking make them one of the most remarkable groups of bees. In the Neotropics, they comprise over 100 species occurring in tropical and subtropical environments including islands in the ...
