Abstract:

A new device for assessing Varroa destructor (Anderson–Truman) mite infestations in honey bee colonies was designed, tested, and evaluated against the sugar roll method, a widely used method by beekeepers. The Varroa Shaker Device (VSD) is constructed of polyvinyl chloride (PVC) pipe that separates into three parts. Inside the shaker there are two mesh sizes; the larger mesh separates the bees from the mites, and the smaller mesh captures the mites. The VSD can be used by shaking bees with only water as the wash solution. The recovery of mites using the VSD is >90%, which is such as that re

Abstract:

Maximum incidence of Varrosis on adults of Apis mellifera L. (8%) was recorded in second fortnight of May 2008 corresponds to the peak in V. destructor population. Percent deformity was calculated by observing 100 adult bees. Deformity in adult bees was low which ranged between 0.0 to 3.0 per cent with an average of 0.52 per cent. Significant positive correlation (r = 0.77) was calculated between per cent mite infestation and per cent bee deformity which revealed that with increase in mite infestation, there was a corresponding increase in deformity of bees.

Abstract:

Varroa destructor Anderson and Trueman, is an ectoparasitic mite of honey bees, Apis mellifera L., that has been considered a major cause of colony losses. Synthetic miticides have been developed and registered to manage this ectoparasite, however, resistance to registered pyrethroid and organophosphate Varroacides have already been reported in Canada. To test toxicity of miticides, current contact-based bioassay methods are designed to evaluate mites and bees separately, however, these methods are unlikely to give an accurate depiction of how miticides interact at the colony level.

Abstract:

RÉSUMÉLe principal objectif de cet article est d’encourager une approche plus large, supraconfessionnelle, du mariage et de la famille à l’époque moderne. La conjugalité a été “désacralisée” par les réformateurs protestants du 16e siècle. Martin Luther, parmi d’autres, a refusé le statut de sacrement au mariage, tout en valorisant celui-ci comme une arme contre le péché. En réaction, le concile de Trente a réaffirmé avec force que le mariage est bien un des sept sacrements chrétiens. Mais, promouvant la supériorité du célibat, l’Église catholique n’a jamais beaucoup insisté sur les vertus de l

Abstract:

Identification of quantitative trait loci for Fusarium head blight (FHB) resistance from different sources and pyramiding them into cultivars could provide effective protection against FHB. The objective of this study was to characterize a soft red winter wheat (SRWW) breeding population that has been subjected to intense germplasm introduction and alien introgression for FHB resistance in the past. The population was evaluated under misted FHB nurseries inoculated with Fusarium graminearum infested corn spawn for two years. Phenotypic data included disease incidence (INC), disease severity (S

Abstract:

Abstract Pollination by insects is vital for global agriculture, with honey bees (Apis mellifera L.) being the most important pollinators. Honey bees are exposed to numerous stressors, including disease, pesticides, and inadequate nutrition, resulting in significant colony losses. This study investigates the use of drone brood to mitigate these problems. Drone brood, which is normally discarded during varroa mite (Varroa destructor, Anderson and Trueman) management, is rich in proteins, fats, and essential minerals. We compared drone brood with an already suggested pollen supplement (Tenebrio

Abstract Honey bees use grooming to defend against the devastating parasite Varroa destructor Anderson and Trueman. We observed the grooming responses of individual bees from colonies previously chosen for high- and low-grooming behavior using a combination of mite mortality and mite damage. Our aim was to gain insight into specific aspects of grooming behavior to compare if high-grooming bees could discriminate between a standardized stimulus (chalk dust) and a stimulus of live Varroa mites and if bees from high-grooming colonies had greater sensitivity across different body regions than bees

Dopamine receptors show promise in this regard in their association with numerous traits in honey bees, high plasticity, and indicated association with varroa resistance through QTL analysis.

Abstract Parasitism from Varroa mites (Varroa destructor Anderson and Trueman, Mesostigmata: Varroidae) is a major driver of honey bee colony losses (Apis mellifera L., Hymenoptera: Apidae). While synthetic miticides are valuable for Varroa management, high reliance on these compounds has selected for miticide-resistant Varroa populations. To enable more sustainable Varroa management and provide options when synthetic miticides such as amitraz fail, effective Integrated Pest Management (IPM) approaches are urgently needed.

Abstract Agrochemical exposure is a major contributor to ecological declines worldwide, including the loss of crucial pollinator species. In addition to direct toxicity, field-relevant doses of pesticides can increase species’ vulnerabilities to other stressors, including parasites. Experimental field demonstrations of potential interactive effects of pesticides and additional stressors are rare, as are tests of mechanisms via which pollinators tolerate pesticides.

AbstractThe parasitic mite Varroa destructor (Anderson & Trueman) spends the dispersal phase of its life cycle on adult honeybees (Apis mellifera L.). The meaning of this phase for both bees and mites is still not well understood. This especially applies to prolonged dispersal phases as a result of brood interruptions. Hence, it is highly important to unravel this phase for understanding the underlying biological mechanisms and implementing this knowledge in beekeeping practice and research efforts.

Among selected traits, mite fertility and fecundity, often referred to as suppressed mite reproduction are increasingly used in breeding programmes. However, the current literature leaves some gaps in the assessment of the effectiveness of selecting these traits toward achieving resistanc
