These well-nourished, long-lived bees have been called “fat” bees (Sommerville 2005; Mussen 2007). Fat bees are chock-full of vitellogenin. Understanding the concept of fat bees is key to colony health, successful wintering, spring buildup, and honey production.

2014年10月1日 · Scattered all through the body cavity of the honey bee but especially in the abdomen are irregular masses of a soft, usually white tissue composed of large, loosely united cells. These cell masses are known collectively as the fat body because the cells contain, enmeshed in their cytoplasm, small droplets of oily fat (Snodgrass and Erickson 1992).

2024年7月29日 · Fat bees are winter bees – bees much better suited to get through the winter, as follows: A compound called vitellogenin helps bees store food reserves in their body. This is less necessary in the summer when they can freely move to and consume food. But in the winter, vitellogenin becomes more important, so a fat bee has more.

2023年8月30日 · They may look the same but workers in the Winter hive are fat bees. Or least they should be-to increase the chances of colony survival. With the ability to live much longer …

A ll insects have fat bodies—tissues that contain lipids, glycogen, triglycerides, and some protein. Fat bodies store energy when food is plentiful and release energy when the bee needs it. The energy stored within these tissues is especially important during larval growth.

Even though a bee is able to fly for two, three, or more miles to reach flowers, the time and metabolic costs involved to traverse such distances may result in meager net returns. The most productive foraging is done within a half mile of the beeyard—an area of about a square mile.

2019年8月25日 · Fat winter bees have more fat bodies; cells that function like a liver, in that they store fat, carbohydrates, and energy, and form a part of the bee’s immune system. Fat cells store cholesterols and nutrients that will be fed to the larval bees that are raised after the winter solstice.

Fat bees and a large-sized colony want to rear brood, build protein reserves, forage, and swarm to expand. High-vitellogenin titers enable the nurse bees, queens, and winter bees to live longer, under less stress, and be more resistant to disease.

2025年2月14日 · “Winter Bees” are a generation of honeybees born in the late summer or early fall months that are designed specifically to survive the winter months. Compared to the 4-6 weeks that a ‘summer bee’ will live, winter bees can survive for months. Sometimes referred to as “Fat Bees”, winter bees have a different anatomical makeup than other bees.
