Abstract

 

Gut microbiomes play crucial roles in animal health, and shifts in the gut microbial community structure can have detrimental impacts on hosts. Studies with vertebrate models and human subjects suggest that antibiotic treatments greatly perturb the native gut community, thereby facilitating proliferation of pathogens. In fact, persistent infections following antibiotic treatment are a major medical issue. In apiculture, antibiotics are frequently used to prevent bacterial infections of larval bees, but the impact of antibiotic-induced dysbiosis (microbial imbalance) on bee health and susceptibility to disease has not been fully elucidated. Here, we evaluated the effects of antibiotic exposure on the size and composition of honeybee gut communities. We monitored the survivorship of bees following antibiotic treatment in order to determine if dysbiosis of the gut microbiome impacts honeybee health, and we performed experiments to determine whether antibiotic exposure increases susceptibility to infection by opportunistic pathogens. Our results show that antibiotic treatment can have persistent effects on both the size and composition of the honeybee gut microbiome. Antibiotic exposure resulted in decreased survivorship, both in the hive and in laboratory experiments in which bees were exposed to opportunistic bacterial pathogens. Together, these results suggest that dysbiosis resulting from antibiotic exposure affects bee health, in part due to increased susceptibility to ubiquitous opportunistic pathogens. Not only do our results highlight the importance of the gut microbiome in honeybee health, but they also provide insights into how antibiotic treatment affects microbial communities and host health.

Author summary There is growing evidence for the importance of gut microbes in animal health. Unlike most other insects, honeybees possess a highly conserved gut microbial community, which is acquired through social contact, and several results have suggested that these microbes play an important role in honeybee health. Antibiotics, which can severely disrupt gut microbial communities, are commonly used in beekeeping in several countries. However, it is unknown how antibiotic treatment affects the gut microbial communities of honeybees. Here, we evaluated the effects of antibiotic treatment on the size and composition of the honeybee gut microbiome and on honeybee health. We found that exposure to antibiotics significantly alters the honeybee gut microbial community structure and leads to decreased survivorship of honeybees in the hive, likely due to increased susceptibility to infection by opportunistic pathogens.

USA- NEONICOTINOIDS PRODUCER ANNOUNCES A PROGRAM TO IMPROVE THE HEALTH OF THE BEES, INSTEAD OF PRODUCING SAFER PRODUCTS FOR BEES

19. veebruar 2016 - 13:03

Bayer press release

 

 

 

Bayer and Project Apis m. today announced they are partnering to sponsor research to improve the health of honey bee colonies in the United States within the next five years.

 

A multi-year, $1 million research effort, Bayer's Healthy Hives 2020 initiative brought together a diverse group of bee experts to prioritize the most urgent research areas needed to improve the health of U.S. colonies by the end of 2020. Project Apis m., the leading non-profit organization dedicated to pollination research, will oversee the administration of the Bayer-funded research grants which are focused on the following major research objectives:

  • Conducting an economic assessment of the "true" cost of commercial beekeeping operations to help beekeepers maximize efficiency and production;
  • Creating a set of "Best Management Practices" for commercial beekeeping based on definitive colony health performance data;
  • Evaluating the use of "smart hive" technology to monitor honey bee colony health during commercial migratory operations; and,
  • Assessing honey bee genetics for traits that are relevant to colony resistance to pests and diseases, as well as pollination efficiency and honey production in the United States.

"While the overall number of honey bee colonies continues to increase, they are still being impacted by a wide range of health-related issues," said Christi Heintz, executive director of Project Apis m., Paso Robles, California. "In issuing a request for proposals, our goal is to identify scientists and promising research initiatives that can help solve some of the most critical concerns facing beekeepers today."

Proposals should address one or more of the key focus areas and include qualifications of the research team, proposed timelines, deliverables and budget. According to Heintz, the intent is to conduct multi-year investigations with annual reports on progress toward achieving project goals. The deadline for submissions is 5 p.m., PST, Tuesday, March 1, 2016.

The new research effort arose out of Bayer's Healthy Hives 2020 initiative, which launched in 2015 with a two-day workshop that brought together some of the nation's leading bee health experts and stakeholders at the Bayer North American Bee Care Center in Research Triangle, North Carolina. The 17 summit workshop attendees identified a wide range of bee health concerns which were later reviewed by the Healthy Hives 2020 Steering Committee and prioritized into the most promising areas of research that were announced today.

"Today's announcement represents a collaborative effort of some of the country's leading bee health stakeholders including beekeepers, academic researchers, governmental officials and industry representatives," said Dr. Steve Sheppard, professor of entomology and departmental chair at Washington State University, Pullman, Washington, who chairs the Healthy Hives 2020 Steering Committee.

Healthy Hives 2020 is one of several activities of Bayer's North American Bee Care Program. "We have supported and promoted bee health for nearly 30 years," said Dr. David Fischer, director of pollinator safety, Crop Science, a division of Bayer. "Because of the critical role honey bees play in crop pollination, we have long recognized that a vibrant beekeeping industry is vital to maintaining sustainable agriculture."

Other Bayer bee health programs include:

  • Establishing the North American Bee Care Center two years ago as a focal point for education, research and collaboration, hosting more than 6,000 visitors;
  • Launching Feed a Bee, a major honey bee forage initiative that engaged more than 250,000 consumers last year to distribute seed to plant more than 65 million flowers; and,
  • Forming more than 70 partnerships with a wide range of organizations to plant thousands of acres of forage for honey bees.

USA- CHLORPYRIPHOS (LORSBAN) INSECTICIDE MUST BE USED MORE CAREFULLY

17. veebruar 2016 - 19:48

By Patrick Cavanaugh

 

California Department of Pesticide Regulation (DPR) reports an important, broad-spectrum organophosphate insecticide known asChlorpyriphos, or Lorsban, may be further restricted due to evidence of potential human health and environmental risks, presence (parts per billion) in some California waterways, and pressure from the EPA. Brian Leahy, director of the California Department of Pesticide Regulation, said, “Chlorpyriphos is an important tool and we know there are important times when you have to use it.”

Registered and widely used in agriculture across the nation for more than 40 years, DPR has made it a restricted-use material. Leahy said, “We are trying to work with the grower community to improve how they use it. We are also working with UC IPM to look at essential needs, but we know that as we look at Chlorpyriphos, we are going to have to put additional restrictions on it.”

“We simply need for it to stay on target, and not be getting into the human body. We are seeing that it is, and we are going to continue to make sure that people use it thoughtfully and wisely,” he said.

And Leahy is very confident that growers can use this material and keep it on target, “I have seen farms that use it only when they really need it, and that is what we want. We can’t lose this tool and we are going to keep it only by showing we can greatly reduce off-site movement to the human body and watersheds,” he noted.

According to the University of California Agriculture and Natural Resources 2014 Chlorpyrifos Report entitled, “Identifying and Managing Critical Uses of Chlorpyrifos Against Key Pests of Alfalfa, Almonds, Citrus and Cotton“:

Chlorpyrifos plays a critical role in many IPM programs for controlling pests that threaten the productivity and economic well-being of California producers and in maintaining the high quality standards required by consumers and international export markets. This active ingredient also allows production of animal feed to support the important dairy industry in California. For some pests, chlorpyrifos is one of the last effective organophosphate insecticides available and may provide an important alternative mode of action for insecticide rotations to prevent the development of resistance to newer insecticide products. For others, this product is one of very few products with international registrations with established maximum residue limits (MRLs) that allow unhampered trade. Chlorpyrifos may also be a key tool for controlling invasive pests as well as endemic pests occasionally found in extremely high population densities.

The California Department of Pesticide Regulation reports that the combined use of chlorpyrifos in alfalfa, almonds, citrus, and cotton has decreased since 2006.

Although newer insecticides are also available to manage some pests in these four crops, there is a continued need to preserve the availability of chlorpyrifos for specific situations.

ITALY- A MUTUALISTIC SYMBIOSIS BETWEEN A PARASITIC MITE AND A PATHOGENIC VIRUS UNDERMINES HONEY BEE IMMUNITY AND HEALTH

Significance

The parasitic mite Varroa destructor and the deformed wing virus (DWV) are linked in a mutualistic symbiosis. The mite acts as vector of the viral pathogen, whereas the DWV-induced immunosuppression in honey bees favors mite feeding and reproduction. This functional interaction underpins a rapidly escalating immunosuppression, which can be primed and/or aggravated by a wealth of stress factors that co-trigger colony losses. Our experimental results explain the pivotal role proposed for the Varroa–DWV association in the induction of honey bee colony losses. Here we provide a functional framework for studying the dynamics of this multifactorial syndrome and defining effective strategies to reduce its negative impact on the beekeeping industry.

 

 

Abstract

Honey bee colony losses are triggered by interacting stress factors consistently associated with high loads of parasites and/or pathogens. A wealth of biotic and abiotic stressors are involved in the induction of this complex multifactorial syndrome, with the parasitic mite Varroa destructor and the associated deformed wing virus (DWV) apparently playing key roles. The mechanistic basis underpinning this association and the evolutionary implications remain largely obscure. Here we narrow this research gap by demonstrating that DWV, vectored by the Varroa mite, adversely affects humoral and cellular immune responses by interfering with NF-κB signaling. This immunosuppressive effect of the viral pathogen enhances reproduction of the parasitic mite. Our experimental data uncover an unrecognized mutualistic symbiosis between Varroa and DWV, which perpetuates a loop of reciprocal stimulation with escalating negative effects on honey bee immunity and health. These results largely account for the remarkable importance of this mite–virus interaction in the induction of honey bee colony losses. The discovery of this mutualistic association and the elucidation of the underlying regulatory mechanisms sets the stage for a more insightful analysis of how synergistic stress factors contribute to colony collapse, and for the development of new strategies to alleviate this problem.

CAMEROON- FORAGING AND POLLINATION BEHAVIOR OF APIS MELLIFERA ASNASONI LATERILLE ON BRACHIARIA BRIZANTHA STAPF 1919 FLOWERS AT DANG

Abstract
To evaluate the Apis mellifera adansonii Latreille (Hymenoptera: Apidae) impact on fruit and seed yields of Brachiaria brizantha H. (1919) (Poaceae), A. m. adansonii workers foraging and pollinating activities were studied in Ngaoundéré. From September to October 2010 and from September to October 2011, the experiments were carried out on 240 and 440 inflorescences divided in three lots: two lots differentiated according to the presence or absence of protection regarding A. m. adansonii and other insects visits; the third protected and uncovered when flowers were open, to allow insect visits. Worker’s seasonal rhythm of activity, its foraging behavior on flowers, its pollination efficiency, the fructification rate and the percentage of normal seeds were evaluated. Results show that A. m. adansonii foraged on B. Brizantha flowers throughout the whole blooming period. This bee intensely and preferably harvested pollen. The greatest mean number of individuals foraging simultaneously on 1000 flowers was 10 in 2010 and 625 in 2011. The mean duration of a visit per spikelet was 5.77 ± 5.08 sec in 2010 and 4.94 ± 3.44 sec in 2011. The mean foraging speed was 4.55 flowers/min in 2010 and 6.86 flowers/min in 2011. The fructification rate and the percentage of normal seeds of unprotected inflorescences were significantly higher than those of inflorescences protected from insects. Through its pollination efficiency, A. m. adansonii provoked a significant increment of the fructification rate by 37.70 % in 2010 and 34.75 % in 2011, as well as the percentage of normal seeds by 3.39 % in 2010 and 6.82 % % in 2011. The installation or conservation of A. m. adansonii nests close to B. brizantha fields could be recommended to increase seeds and fruits production in the region
