Introduction

The honey bee tracheal mite (Acarapis woodi) was first described in 1921 by Rennie, who believed the mite was the cause of the Isle of Wight Disease, after dissecting infected honey bees (Apis mellifera) from colonies on the island off the coast of England (Henderson and Morse 1990). Between …

2017 Bee Health Webinar Series: Ensuring Crop Pollination in US Specialty Crops

Webinar banner

This webinar series will provide an overview of pollination requirements and strategies to ensure pollination of different specialty crops. Farmers and gardeners rely on crop pollinators, including honey bees, alternative managed bees like the blue orchard bee, and wild bees. Pollination experts will discuss how to support these pollinators in almond, blueberry, tree fruit, pumpkin, and watermelon. Webinars will take place on selected Tuesdays at 11a.m. Pacific time, noon Mountain time, 1 p.m. Central time, 2 p.m. Eastern time.  Registration

Integrated Crop Pollination

What is Integrated Crop Pollination?

Integrated crop pollination is the combined use of multiple pollinator species, habitat augmentation, and crop management practices to provide reliable and economical pollination of crops. Pollinator species can include managed honey bees, alternative managed bees, and many different types of wild bees. Habitat augmentation refers to adding floral and nesting resources to farms (e.g. wildflower strip, meadows, and hedgerows). Crop management practices that support pollination include modifying pest management practices to reduce risks to pollinators, …

Pollination and Protecting Pollinators

Washington State Pollination Video

Pollination in agriculture and why it matters.

Pollination and Protecting Pollinators from WSU CAHNRS Video Production on Vimeo.

Honey bees are the most important pollinator in the United States and worldwide. Pollination is essential and a critically important process in producing much of the food we eat. Without pollinators, such as the honey bee, we would have few fruits, vegetables, nuts and many other types of food we depend upon. This 52-minute video gives an overview of the pollination

Can a honey bee be born without the aid of a drone?

Yes and no. A drone’s (male bee) purpose is to mate with a queen (female reproductive bee). All other colony activities are performed by worker bees (female bees). To discuss how a bee is born, we can start with when the egg is laid. Generally speaking, if the queen fertilizes this egg with sperm, it will become a worker bee, or another queen. If she does not fertilize the egg, it will become a drone (male). The care and feeding …

How do I know whether my bees have Nosema disease?

The only way to be sure is to examine bees by microscope. A sample of bees is macerated in a small amount of water, and then a drop of the liquid is examined on a microscope slide at 400 power. Spores appear as ovals, about 3 by 5 microns. One outward indication of Nosema is brown spots (fecal material) on the outside or inside of a hive. The inner cover or top bars can be soiled with feces in a …

What are some ways to reduce the population of Varroa mites in honey bee colonies, without the use of pesticides?

Mite-resistant Bees. In response to development of resistance to chemical miticides, and in order to provide more sustainable mite management, honey bees have been selectively bred for resistance to, or tolerance of, Varroa. There are two known mechanisms of resistance: hygienic behavior and suppression of mite reproduction (SMR). Hygiene is the removal of diseased (including mite-parasitized) brood by workers; SMR is the reduction in reproduction of female mites within brood cells. Types of resistant queens include; Minnesota Hygienic, the Russian …

How do honey bees make wax?

Bees produce the beeswax used in the construction of their combs from the four pair of wax glands located on the underside of the abdomen. These glands are most highly developed and active in bees 10-18 days old. The wax appears in small, irregular oval flakes or scales that project between the overlapped portions of the last four abdominal segments. Wax can be secreted only at relatively high temperatures and after a large intake of honey or nectar. -John Skinner, …

How is Nosema disease treated?

Nosema disease can be treated successfully with Fumigillin (trade name Fumidil). Colonies are usually treated in the fall, spring, or both. Follow the directions on the label and feed the correct dosage in 50% sugar syrup (1:1 sugar:water, with antibiotic dissolved in 5-10 ml warm water then mixed into the syrup) in the spring, 66% in the fall. Nosema ceranae also responds to Fumidil treatment, but may require a higher dosage. The antibiotic does not kill the spores, but disrupts …
