Abstract Screening of the prevalence of Paenibacillus larvae spores in honey bee colonies in apiaries from 162 districts, belonging to nine provinces was carried out during 2009-2011. The honey samples were examined by the use of a culture method. Based on the number of CFUs grown on Columbia sheep blood agar medium, the level of infection and probability of American foulbrood outbreak was estimated. Altogether, 6,510 pooled honey samples from 32,550 bee colonies located in 2,294 apiaries were collected. P. larvae was identified in 45% of the surveyed apiaries. The widest distribution of P. larvae was found in the Małopolskie province. Culture-positive honey samples were obtained for 71% of the apiaries and in a half of them, the level of spores was high. In the Warmińsko-Mazurskie province, the presence of the bacterium was detected in 58% of the apiaries. In the remaining provinces, from 26% to 47% of the apiaries were contaminated with P. larvae spores

Abstract Global western honey bee, Apis mellifera (L.) (Hymenoptera: Apidae), colony declines pose a significant threat to food production worldwide. Poor nutrition resulting from habitat loss, extensive monocultures, and agricultural intensification is among the several suggested drivers for colony declines. Pollen is the primary source of protein for honey bees; therefore, both pollen abundance and diversity are critical for colony growth and survival. Many cropping systems that employ honey bee colonies for pollination may lack sufficient pollen diversity and abundance to provide optimal bee nutrition. In this observational study, we documented the diversity and relative abundance of pollen collected by honey bees in five major pollinator-dependent crops in the western United States. We sampled pollen from pollen traps installed on honey bee colonies in the following cropping systems—almond, cherry, highbush blueberry, hybrid carrot, and meadowfoam. The pollen diversity was estimated by documenting the number of different pollen pellet colors and plant taxa found in each pollen sample. The lowest pollen diversity was found in almond crop. Relatively higher quantities of pollen collection were collected in almond, cherry, and meadowfoam cropping systems. The information gleaned from this study regarding pollen diversity and abundance may help growers, land managers, and beekeepers improve pollen forage available to bees in these cropping systems.

European foulbrood is a bacterial disease that affects Western honey bee larvae. It is a concern to beekeepers everywhere, though it is less serious than American foulbrood because it does not form spores, which means that it can be treated. This 7-page fact sheet written by Catherine M. Mueller, Cameron J. Jack, Ashley N. Mortensen, and Jamie Ellis and published by the UF/IFAS Entomology and Nematology Department describes the disease and explains how to identify it to help beekeepers manage their colonies effectively and prevent the spread of both American and European foulbrood.https://edis.ifas.ufl.edu/in1272
