Honey Bee Tracheal Mites: Gone? But not for Good

Authors: Philip A. Moore, Michael E. Wilson, John A. Skinner
Department of Entomology and Plant Pathology, the University of Tennessee, Knoxville TN
Originally Published: August 4, 2015

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 …

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, …

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 …

What is Nosema disease?

Nosema disease in honey bees is caused by two species of pathogens, Nosema apis and Nosema ceranae. Nosema apis was the only known microsporidian honey bee pathogen until 1996, when a second species, Nosema ceranae, was identified from the Asian honey bee. Nosema ceranae appears to be the dominant species in the European honey bee (Apis mellifera) in many parts of the world, including in Europe and the United States. Both of these pathogens cause chronic deleterious effects in the …

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 …

Brief Description:
Recent declines in honey bees for crop pollination threaten fruit, nut, vegetable and seed production in the United States. A broad survey of pesticide residues was conducted on samples from migratory and other beekeepers across 23 states, one Canadian province and …

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, …

What are wax moths and what kind of damage do they make in a beehive?

There are two species of wax moth that cause damage to honey bee colonies by consuming beeswax as their larvae develop and in the process of making a pupal cocoon they score the wooden frames that hold the wax combs, weakening the wood. Damage becomes obvious as they produce large quantities of gray-white webbing and dark fecal material as they feed. The larger of the two species (3/4 inch long gray-brown adult), the greater wax moth, Gallaria melonella causes more …

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 …
