Urban Landscape Influence Orchid Bee Diversity in a Tropical Megacity
Journal of Applied Entomology, EarlyView.ABSTRACT The increasing urbanization has affected pollinator communities, such as Euglossini bees, which play a crucial role in maintaining biodiversity through the pollination of numerous plants. However, the impact of different levels of urbanization on the diversity of these bees is still not fully understood, especially in large tropical urban ...

Ecological 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
Ecological 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.
