The Buzz about Honey Bee Viruses

High annual losses of honey bees, as well as range reductions and local extinctions of wild and native pollinator species, are concerning because bees are important plant pollinators [1]. Approximately one-third of the typical Western diet requires bee pollination, and honey bees (Apis mellifera) are the primary pollinators of numerous food crops, including fruits, nuts, vegetables, and oilseeds [2].

Comparison of Productivity of Colonies of Honey Bees, Apis mellifera, Supplemented with Sucrose or High Fructose Corn Syrup

Honey bee colony feeding trials were conducted to determine whether differential effects of carbohydrate feeding (sucrose syrup (SS) vs. high fructose corn syrup, or HFCS) could be measured between colonies fed exclusively on these syrups. In one experiment, there was a significant difference in mean wax production between the treatment groups and a significant interaction between time and treatment for the colonies confined in a flight arena.

Chalkbrood disease in honey bees

Chalkbrood disease is typically most prevalent during the spring, given that fungal growth is enhanced in cool and humid (poorly ventilated) beehives (Mehr et al., 1976; Gilliam et al., 1978; Puerta et al., 1994; Flores et al., 1996; Borum and Ulgen, 2008).

Honey Bee (Apis mellifera) Queen Reproductive Potential Affects Queen Mandibular Gland Pheromone Composition and Worker Retinue Response

Reproductive division of labor is one of the defining traits of honey bees (Apis mellifera), with non-reproductive tasks being performed by workers while a single queen normally monopolizes reproduction.

Winter Survival of Individual Honey Bees and Honey Bee Colonies Depends on Level of Varroa destructor Infestation

Recent elevated winter loss of honey bee colonies is a major concern. The presence of the mite Varroa destructor in colonies places an important pressure on bee health. V. destructorshortens the lifespan of individual bees, while long lifespan during winter is a primary requirement to survive until the next spring.

United States Honey Production Down 9 Percent for Operations with Five or More Colonies in 2017

United States honey production in 2017 from producers with five or more colonies totaled 148 million pounds, downUnited States honey production in 2017 from producers with five or more colonies totaled 148 million pounds, down9 percent from 2016. There were 2.67 million colonies producing honey in 2017, down 4 percent from 2016. Yield per colony averaged 55.3 pounds, down 5 percent from the 58.3 pounds in 2016.

Unravelling the Molecular Determinants of Bee Sensitivity to Neonicotinoid Insecticides

The impact of neonicotinoid insecticides on the health of bee pollinators is a topic of intensive research and considerable current debate [1]. As insecticides, certain neonicotinoids, i.e., N-nitroguanidine compounds such as imidacloprid and thiamethoxam, are as intrinsically toxic to bees as to the insect pests they target.

Draft Guidance for Industry: Declaration of Added Sugars on Honey, Maple Syrup, and Certain Cranberry Products

The purpose of this draft guidance is to advise food manufacturers of our intent to exercise enforcement discretion related to the use in the Nutrition Facts label of a symbol immediately after the added sugars percent Daily Value information on single-ingredient packages and/or containers of pure honey or pure maple syrup and on certain dried cranberry and cranberry juice products that are sweetened with added sugars and that contain total sugars at levels no greater than comparable products with endogenous (inherent) sugars, but no added sugars.

New Zealand's highest rate of colony loss

South Canterbury beekeepers have faced a challenging summer with drought and the varroa mite impacting hives.

The Ministry for Primary Industries (MPI) released its Bee Colony Loss Survey report for 2017 on March 16, which sampled 30 per cent of New Zealand beekeepers to determine the rate of hive loss and the main reasons for it.

MPI aquatic and environment health manager Dr. Michael Taylor said a severe drought for the middle of the South Island last year was the leading contributor to the jump in colony loss.

The drought's main impact was causing nectar and pollen sources to deplete, leading to bees dying from starvation, Taylor said.

For the middle of the South Island, encompassing Canterbury and the West Coast, the loss was 11.4 per cent compared to 7.2 per cent in 2016.

Pleasant Point Apiaries beekeeper Paul Bartrum said, however, the varroa mite - a parasite that attaches to bees and sucks fat from them - has been the main killer of his South Canterbury hives because the mites are gaining a resistance to treatments.

CATCH THE BUZZ : 16 Grants to Address Declining Pollinator Health.

WASHINGTON, March 13, 2018 -The Foundation for Food and Agriculture Research, a nonprofit established through bipartisan congressional support in the 2014 Farm Bill, today announced 16 grants totaling $7 million for research to address declining pollinator health, an ongoing threat to agricultural productivity in the United States. The FFAR awards are matched by more than 50 companies, universities, organizations and individuals for a total investment of $14.3 million toward research and technology development.
