ECOLOGICAL ENTOMOLOGY 09/06/16 Patterns in Varroa destructor depend on bee host abundance, availability of natural resources, and climate in Mediterranean apiaries

Varroa destructor Linnaeus (Acari: Varroidae) is one of the greatest threats to apiculture. This study examines the role of host density, natural resource availability for bees, the management and climate in driving spatial and annual variability in the abundance of Varroa, and the occurrence of colony losses, recorded in apiaries across a Mediterranean island over a 2-year period, using a hierarchical generalised linear model framework. 2. The seasonal abundance of Varroa showed a bimodal pattern with two peaks, the first one being in spring and larger than the second one located in summer/autumn. In contrast, bee colony losses were mainly concentrated in autumn/winter. 3. 4.

Breeding for strains with the VSH (varroa specific hygiene) trait has resulted in some of Rainbow Honey’s hives in the Nelson area completely overcoming mite infestation. Meanwhile Ron van Toor, of Plant and Food, says certain types of chelifer (aka pseuodo-scorpions) show potential for their ability to attack varroa in beehives, or any other new mite incursion which could become a problem.

EMEA 07/10/16 New medicine to protect honey bees against Varroa mites

This antiparasitic medicine treats the Varroa mite infestation in honey-bee colonies, which is considered to be the most significant parasitic health concern affecting honey bees worldwide. Honey bees are essential for pollination of crops and wild plants in Europe. The European Commission estimates that pollinators, including honey bees, bumble bees and wild bees, contribute at least 22 billion euros each year to European agriculture and pollinate over 80% of crops and wild plants on the continent.

Approach: The major objectives of this proposal are to increase our understanding of Tropilaelaps spp. parasitism and control in Apis mellifera and comparisons of Thai sacbrood and Nosema infectivity in A. mellifera and Apis cerana.

EPA - JANV 2016 - EPA-registered Pesticide Products Approved for Use Against Varroa Mites in Bee Hives

Varroa mites are parasites that feed on developing bees, leading to brood mortality and reduced lifespan of worker bees. They also transmit numerous honeybee viruses. The health of a colony can be critically damaged by an infestation of Varroa mites. Once infested, if left untreated, the colony will likely die. By expediting the approval of pesticides that target Varroa mites and publishing information about the products, EPA is honoring another commitment in the National Strategy. The pesticide products listed on this page are registered by EPA at the federal level for use against Varroa mites.

ARMERS GUARDIAN 13/05/13 US report cites varroa mite as major factor in bee decline

The report by the US Department of Agriculture (USDA) and the US Environmental Protection Agency (EPA) concludes the parasitic varroa mite is ‘recognised as the major factor underlying colony loss in the US and other countries’. It highlights various other factors, including disease, genetics, poor nutrition and pesticide exposure. In contrast to the recent European decision to suspend three neonicotinoid seed treatments on the basis of a risk assessment by the EU food safety authorities, the US report concludes additional research is needed to determine the risks presented by pesticides. The report echoes the conclusion of a conference on the impact of agriculture on insect populations that bee decline was a ‘multi-factorial issue’, with more research needed on the impact neonicotinoids in the field.

THE ROYAL SOCIETY - JUNE 2015 - BIOLOGY LETTERS - Varroa destructor changes its cuticular hydrocarbons to mimic new hosts

Its original host is the Asian honeybee, Apis cerana, but it has also become a severe, global threat to the European honeybee, Apis mellifera. Previous studies have shown that Varroa can mimic a host's cuticular hydrocarbons (HC), enabling the parasite to escape the hygienic behaviour of the host honeybees. By transferring mites between the two honeybee species, we further demonstrate that Vd is able to mimic the cuticular HC of a novel host species when artificially transferred to this new host. Mites originally from A. cerana are more efficient than mites from A. mellifera in mimicking HC of both A. cerana and A. mellifera. 1.

Issue: 11 The Effects of Varroa (Varroa destructor) Infestat

Poor struggle against parasites and diseases of honeybees and bad management conditions could be the main reasons of this fact (Kumova, 2003). Varroa damage is one of the most important factors that increases the wintering loses (Akyol et al., 2006b). When the varroa infestation increases, resistance of the colonies decreases againist the bad conditions (Kumova, 2003). High levels of varroa infestation may reduce the pupae and adult weight of the honeybees >10% (Gueler and Kaftanoglu, 1999).

One varroa fed with hemolymph of the honeybees could cause 0.1-0.2% loss of body weight every 2 h. The rate of varroa infestation is one of the most important factors that influence colony population, performance and wintering loses of the colonies (Genc and Aksoy, 1992; Goodvin and Eaton, 2001; Kaftanoglu et al., 1995) . = 0.67±0.11) varroa infestation. . = 4.30±0.28) varroa infestation.
