Health properties of bee bread and bee pollen

Bromatologia i Chemia Toksykologiczna, 2022
Pierzga jest naturalnym produktem pszczelim a surowcem do jej wytworzenia jest pyłek kwiatowy. Pyłek kwiatowy zbierany jest przez pszczoły zbieraczki. Zmieszany z niewielką ilością wydzieliny gruczołów ślinowych lub nektaru zostaje przeniesiony do ula.

Honey bee foraging distance depends on month and forage type [PDF]

, 2015
To investigate the distances at which honey bee foragers collect nectar and pollen, we analysed 5,484 decoded waggle dances made to natural forage sites to determine monthly foraging distance for each forage type.

Widespread contamination of wildflower and bee-collected pollen with complex mixtures of neonicotinoids and fungicides commonly applied to crops [PDF]

, 2016
There is considerable and ongoing debate as to the harm inflicted on bees by exposure to agricultural pesticides. In part, the lack of consensus reflects a shortage of information on field-realistic levels of exposure. Here, we quantify concentrations of

Brood-Rearing Enhancing Potential of Manually Packed Pollen Feeding in Comparison with Pollen and Pollen Supplements in Patty Forms

Journal of Apicultural Science, 2020
Dearth-period pollen or pollen supplement feedings have become a common practice to maintain and stimulate the early buildup of honeybee colonies. Not only amount, type and consumption rate of feeds are important but the conversion and its nutrient ...

POLLEN MAKES BEES HOT [PDF]

Journal of Experimental Biology, 2008
![Figure][1] Forager bees like nothing more than a sweet supply of nectar. But bees do not live by nectar alone. One of their main sources of protein is pollen. Knowing that bees have to maintain a reasonably high thoracic temperature for their muscles to power flight, and that foragers'
