A novel system for maintaining Varroa destructor mites on artificial diets and its application for studying mites as a vector for honey bee viruses The mite Varroa destructor is one of the most destructive parasites of the honeybee (Apis mellifera) and the primary cause of colony collapse in most regions of the world. These mites cause serious injury to their hosts and serve as the vector for several harmful honeybee viruses. Progress in the re... Decoupling the effects of nutrition, age and behavioral caste on honey bee physiology,immunity, and colony health Nutritional stress, and especially a dearth of pollen, is considered an important factor associated with honey bee colony losses. Although impaired colony health and colony collapse are anticipated outcomes of nutritional stress, the mechanisms by which this phenomenon occurs are still not well unde... Neutral sterols in honey bee (Apis mellifera) feces Nutrition is important in the malady that is named Colony Collapse Disorder of honey bees and the sterol 24-methylenecholesterol has been previously shown to be selectively transferred from worker honey bees to developing brood in both laboratory and field studies. The mechanism of this selective tr... Larval pheromone disrupts pre-excavation aggregation of Cactoblastis cactorum (Lepidoptera: Pyralidae) neonates precipitating colony collapse The newly eclosed larvae of Cactoblastis cactorum contained their activity to an arena that they form at the base of their eggstick, which they mark with a mandibular gland pheromone. Laboratory and field studies were undertaken to determine if these pre-excavation aggregations, essential to their s... Pesticide residues in conventionally and organically managed apiaries in south and north Florida Honey bee (Apis mellifera) populations in the United States have been declining for many years. The newest disease called “Colony Collapse Disorder (CCD)” has concerned scientists, governmental agencies, non-profit organizations, and the general public. CCD may be attributed to pests and pathogens, ... Toxicity assessment of glyphosate on honey bee (Apis mellifera) spermatozoa During 2016-2017, 33.2% of managed honey bee colonies in the U.S. were lost due to Colony Collapse Disorder (CCD). Commonly used pesticides are among the suspected reasons for bee mortality. N-(phosphonomethyl)glycine (glyphosate) is a widely used herbicide in the U.S. and has previously been shown ... Colony collapse disorder (CCD) and bee age impact honey bee pathophysiology Honey bee (Apis mellifera) colonies continue to experience high annual losses that remain poorly explained. Numerous interacting factors have been linked to colony declines. Understanding the pathways linking dysfunction with symptoms is an important step in understanding the mechanisms of disease. ... Development of a pheromone-based trapping system for the small hive beetle, Aethina tumida (Coleoptera: Nitidulidae) The small hive beetle, Aethina tumida Murray is a European honey bee (Apis mellifera L, Hymenoptera: Apidae) pest that can be destructive to honey bee colonies, causing damage to comb, stored honey and pollen (Hepburn and Radloff 1998). Although not a direct cause of Colony Collapse Disorder (CCD)... Allee effects and colony collapse disorder in honey bees We propose a mathematical model to quantify the hypothesis that a major ultimate cause of Colony Collapse Disorder (CCD) in honey bees is the presence of an Allee effect in the growth dynamics of honey bee colonies. In the model, both recruitment of adult bees as well as mortality of adult bees have... Israeli acute paralysis virus: epidemiology, pathogenesis and implications for honey bee health and Colony Collapse Disorder (CCD) Israeli acute paralysis virus (IAPV) is a widespread RNA virus that was linked with honey bee Colony Collapse Disorder (CCD), the sudden and massive die-off of honey bee colonies in the U.S. in 2006-2007. Here we describe the transmission, prevalence and genetic diversity of IAPV, host transcripti... Israeli acute paralysis virus affects sucrose responsiveness and homing ability of forager bees, Apis mellifera The honeybee virus, Israeli acute paralysis virus (IAPV), may be one of the most common stressors that are responsible for the colony losses reported worldwide in recent years. IAPV was found to be tightly correlated with honeybee Colony Collapse Disorder (CCD) in the recent outbreak of CCD in the ...
