Abstract The availability and appropriateness of nesting sites significantly influence the reproductive success and overall welfare of wild bees. Human‐induced factors contribute to the destruction of natural nesting habitats. To address these limi

Osmia bicornis syn. O. rufa is a univoltine bee species in which adults fly in spring and the offspring overwinter as cocooned imagoes. The flight period of solitary bees is short, so methods of control for development and emergence time are needed t

In this study, the pollinating potential of the red mason bee (Osmia bicornis syn. O. rufa) in seed production of a major ornamental plant - Persian cyclamen (Cyclamen persicum), was evaluated under horticultural farm conditions. The study was conduc

The development of methods aimed at activation of imagos at any point of wintering provides a compelling potential avenue to utilize bees for pollination of greenhouse crops during autumn, winter, and early spring. In this study, we tested methoprene

Urbanisation is an expansive process and a majority of insects live in human-modified areas. At the same time, a decrease in pollinator species richness and abundance has recently been observed in Europe, which in turn may have serious ecological and

In this study methoprene, a juvenile hormone analogues, was tested as a factor that stimulates the end of diapause, bee activation and emergence. In addition, the survival of bees was checked when combined with an application of methoprene. The exper

This study discusses the longevity and emergence rate of O. rufa males and females after an extended wintering period in artificial conditions. Experimental activation of the wintering bees was carried out every fifteen days, starting at the end of M

The red mason bee Osmia rufa is a solitary bee belonging to the family Megachilidae, and is prone to nest in aggregations. Each female builds a nest separately in pre-existing cavities such as holes in wood and walls or empty plant stems. This is don

The red mason bee Osmia bicornis L. (Hymenoptera: Megachilidae) belongs to a group of insects that undergo an obligatory diapause in the imago stage. Red mason bees (O. bicornis) consume oxygen during overwintering diapause, and reactive oxygen speci
