Article
Bee pollination is an indispensable component of global food production and plays a crucial role in sustainable agriculture. The worldwide decline of bee populations, including wild pollinators, poses a threat to this system. However, most studies to date are situated in temperate regions where Apini and Bombini are very abundant pollinators. Tropi...

The foraging behaviour of pollinators can influence their efficiency in pollinating certain plant species. Improving our understanding of this behaviour can contribute to an improvement of management techniques to avoid pollination deficits. We investigated the relationship between the number of visits of bumble bees (Bombus impatiens ) to tomato f...

Canola crop productivity is benefited by bee pollination and it has been shown that bee communities can be affected by landscape composition. The aim of this study was to analyse the bee community and its relationship to canola seed production in agricultural areas. The density, abundance and richness of floral visitors of Brassica napus cultivar H...
Article
Seventy five percent of the world's food crops benefit from insect pollination. Hence, there has been increased interest in how global change drivers impact this critical ecosystem service. Because standardized data on crop pollination are rarely available, we are limited in our capacity to understand the variation in pollination benefits to crop y...

The flight distance of bees determines the area they can explore. This area must contain the resources they need to survive and reproduce. It also influences their ability of migration and dispersion. Thereafter, understanding flight distance is crucial for comprehending bee ecology and management for pollination and/or conservation purposes. The a...

In order to protect biodiversity, conservation genetics are of great importance. Until now, a few population genetic studies of Neotropical bumblebees are available but studies of temporal stability in genetic diversity are lacking. Here, genetic variability of three South Brazilian species Bombus bellicosus, B. pauloensis, and B. morio was investi...

Alternative pollinators can ensure pollination services if the availability of the managed or most common pollinator is compromised. In this study, the behavior and pollination efficiency of Apis mellifera L. and two species of stingless bees, Plebeia emerina Friese and Tetragonisca fiebrigi Schwarz, were evaluated and compared in flowers of Brassi...
Article
Extreme environmental conditions may negatively affect the development of animals. Insects show a wide range of adaptive behaviors that have allowed them to respond successfully to adverse climatic conditions by temporarily interrupting some of their activities or development. One such behavior is diapause. Diapause can be defined as a gradual and...

Planning the artificial pollination of agricultural crops requires knowledge of the floral biology and reproductive system of the crop in question. Many studies have shown that rapeseed (Brassica napus Linnaeus) is self-compatible and self-pollinated, but its productivity may be increased by insect visitation. In the present study, the floral biolo...

Colonies of the Brazilian stingless bee Plebeia remota show a reproductive diapause in autumn and winter. Therefore, they present two distinct reproductive states, during which colony needs are putatively different. Consequently, foraging should be adapted to the different needs. We recorded the foraging activity of two colonies for 30 days in both...

Project
The aim of our study is to know the effect of landscape on floral visitation rate and bee communities visiting flowers of a common plant species occurring in the entire country (Brazil) with a standardised and simple protocol. For this reason we choose the plant basilicum (Ocimum basilicum), a common plant growing in the garden of Brazilians.
Project
The main aims are: 1) to investigate the role of flower traits on visitor behavior and on pollination success; 2) verify which species are the blueberry pollinators in Brazil. This project also integrates SURPASS 2: https://bee-surpass.org/
