Distribution, Epidemiological Characteristics and Control Methods of the Pathogen Nosema Ceranae Fries in Honey Bees Apis Mellifera L
Arch Med Vet 47, 129-138 (2015) REVIEW Distribution, epidemiological characteristics and control methods of the pathogen Nosema ceranae Fries in honey bees Apis mellifera L. (Hymenoptera, Apidae) Distribución, características epidemiológicas y métodos de control del patógeno Nosema ceranae Fries en abejas Apis mellifera L. (Hymenoptera, Apidae) X Aranedaa*, M Cumianb, D Moralesa aAgronomy School, Natural Resources Faculty, Universidad Católica de Temuco, Temuco, Chile. bAgriculture and Livestock Service (SAG), Coyhaique, Chile. RESUMEN El parásito microsporidio Nosema ceranae, hasta hace algunos años fue considerado como patógeno de Apis cerana solamente, sin embargo en el último tiempo se ha demostrado que puede afectar con gran virulencia a Apis mellifera. Por esta razón, ha sido denunciado como un agente patógeno activo en la desaparición de las colonias de abejas en el mundo, infectando a todos los miembros de la colonia. Es importante mencionar que las abejas son ampliamente utilizadas para la polinización y la producción de miel, de ahí su importancia en la agricultura, además de desempeñar un papel ecológico importante en la polinización de las plantas donde un tercio de los cultivos de alimentos son polinizados por abejas, al igual que muchas plantas consumidas por animales. En este contexto, esta revisión pretende resumir la información generada por diferentes autores con relación a distribución geográfica, características morfológicas y genéticas, sintomatología y métodos de control que se realizan en aquellos países donde está presente N. ceranae, de manera de tener mayores herramientas para enfrentar la lucha contra esta nueva enfermedad apícola. Palabras clave: parásito, microsporidio, Apis mellifera, Nosema ceranae. SUMMARY Up until a few years ago, the microsporidian parasite Nosema ceranae was considered to be a pathogen of Apis cerana exclusively; however, only recently it has shown to be very virulent to Apis mellifera. -

These authors contributed equally to this work. y Received: 21 February 2020; Accepted: 18 March 2020; Published: 22 March 2020 Abstract: The microsporidium Nosema ceranae is a high prevalent parasite of the European honey bee (Apis mellifera). This parasite is spreading across the world into its novel host. The developmental process, and some mechanisms of N. ceranae-infected honey bees, has been studied thoroughly; however, few studies have been carried out in the mechanism of gene expression in N. ceranae during the infection process. We therefore performed the suppressive subtractive hybridization (SSH) approach to investigate the candidate genes of N. ceranae during its infection process. All 96 clones of infected (forward) and non-infected (reverse) library were dipped onto the membrane for hybridization. A total of 112 differentially expressed sequence tags (ESTs) had been sequenced. -
A Beekeeper's Guide Year in Management for a Virginia Apiary
A BEEKEEPER’S YEAR IN A VIRGINIA APIARY January: Long, cold nights are ideal for talking and reading about your bees. Start the New Year off by attending a beekeeper meeting in your area. Read beekeeping books and magazines. Review successes and failures of past year. Make plans for any needed changes in management and schedule. Assemble and repair beekeeping equipment. Hope for a January thaw so the bees have a cleansing flight. Monitor weights and amount of honey in hives. February: Maples, willows, and other early season plants are in bloom. Make a brief check of wintering colonies for honey and brood (laying queen). Reposition frames with honey and pollen placing them near the brood cluster. First pollen should become available. If low on pollen add a pollen supplement or substitute. Feed bees 1:1 sugar/water syrup on warmer days to minimize winter mortality. If low on honey stores feed 2:1 sugar/water syrup. In late February stimulate brood production by feeding 1:2 sugar/water syrup. March: Dandelion is in bloom. Check colonies on a warm, sunny day. Check for old and rotting wood, frames in disrepair or with old comb, food reserves, and brood pattern and size. If food reserves are short feed 1:1 sugar/water syrup. Colonies that need feeding should be monitored and fed continually as needed. Clean bottom boards. Mid to late March replace solid bottom board with screen bottom board or remove cover from screen. Reverse hive boxes to position brood in lower box. Treat soil for small hive beetle (SHB) where infestations are found. -

Small Hive Beetle
State of Hawai‘i New Pest Advisory DEPARTMENT OF AGRICULTURE No. 12-01 Issued January 2012 Small Hive Beetle Aethina tumida Murray (Coleoptera: Nitidulidae) Jacqueline D. Robson Figure 1: Adult small hive beetle (approx. 3/16” or 5mm) Introduction. In April 2010, a beekeeper in Egypt (2000), Australia (2001), Canada (2002), Pana‘ewa, on the Big Island, contacted Portugal (2004), Mexico (2007) and Hawai‘i HDOA’s entomologist in Hilo about beetles he (2010). In Hawai‘i, SHB is currently widely had found inside his hives. The entomologist distributed on both O‘ahu and the Big Island. It collected four beetles and together with HDOA was also detected on Moloka‘i and Maui in entomologists in Honolulu, made a preliminary 2011 but widespread reports have not yet identification of small hive beetle (SHB). This occurred. was confirmed on April 30, 2010 by the U.S. Department of Agriculture’s National Identification Service in Riverdale, MD. Description. Adult SHB are brown on emergence, changing to black after a few days. Beetles are oval shaped and are approximately 3/16 inch long. In the hive, they run quickly and avoid light. Larvae are off- white and elongated with 2 rows of spines running the length of their dorsal side - they grow to a length of approximately 7/16 inch before pupation. SHB larvae crawl out of the hive and drop to the soil beneath to pupate. Although SHB prefers to live with honey bees, it can also complete its life cycle on several types of fruit found locally.

Targeting the Honey Bee Gut Parasite Nosema Ceranae with Sirna Positively Affects Gut Bacteria Qiang Huang1* and Jay D
Huang and Evans BMC Microbiology (2020) 20:258 https://doi.org/10.1186/s12866-020-01939-9 RESEARCH ARTICLE Open Access Targeting the honey bee gut parasite Nosema ceranae with siRNA positively affects gut bacteria Qiang Huang1* and Jay D. Evans2* Abstract Background: Gut microbial communities can contribute positively and negatively to host health. So far, eight core bacterial taxonomic clusters have been reported in honey bees. These bacteria are involved in host metabolism and defenses. Nosema ceranae is a gut intracellular parasite of honey bees which destroys epithelial cells and gut tissue integrity. Studies have shown protective impacts of honey bee gut microbiota towards N. ceranae infection. However, the impacts of N. ceranae on the relative abundance of honey bee gut microbiota remains unclear, and has been confounded during prior infection assays which resulted in the co-inoculation of bacteria during Nosema challenges. We used a novel method, the suppression of N. ceranae with specific siRNAs, to measure the impacts of Nosema on the gut microbiome. Results: Suppressing N. ceranae led to significant positive effects on microbial abundance. Nevertheless, 15 bacterial taxa, including three core taxa, were negatively correlated with N. ceranae levels. In particular, one co- regulated group of 7 bacteria was significantly negatively correlated with N. ceranae levels. Conclusions: N. ceranae are negatively correlated with the abundance of 15 identified bacteria. Our results provide insights into interactions between gut microbes and N. ceranae during infection.
