Biologically active extracts from different medicinal plants tested as potential additives against bee pathogens

Abstract Honey bees (Apis mellifera) perform pollination service for many agricultural crops and contribute to the global economy in agriculture and bee products. However, honey bee health is an ongoing concern, as illustrated by persistent local population decline, caused by some severe bee diseases (e.g., nosemosis, AFB, EFB, chalkbrood). Three natural recipes are in development…

Honey botanical origin and honey-specific protein pattern: Characterization of some European honeys

Abstract Honey adulteration generates low quality products on the market. The study aimed to find a simple, specific and less time-consuming method than standard melissopalynology only, for monitoring honey botanical and geographical origin. In this study 42 honey samples from different sources were examined for their botanical origin by using melissopalynology and their specific protein…

Impact of microorganisms and entomopathogenic nematodes used for plant protection on solitary and social bee pollinators

Abstract Pollinating bees are stressed by highly variable environmental conditions, malnutrition, parasites and pathogens, but may also by getting in contact with microorganisms or entomopathogenic nematodes that are used to control plant pests and diseases. While foraging for water, food, or nest material social as well as solitary bees have direct contact or even consume…

The Diversity Decline in Wild and Managed Honey Bee Populations Urges for an Integrated Conservation Approach

Many parts of the globe experience severe losses and fragmentation of habitats, affecting the self-sustainability of pollinator populations. A number of bee species coexist as wild and managed populations. Using honey bees as an example, we argue that several management practices in beekeeping threaten genetic diversity in both wild and managed populations, and drive population…
