Book excerpt: Excerpt from The Use of Pollen Traps and Pollen Supplements in Developing Honeybee Colonies The bees usually require several days to become accustomed to the trap. The pollen trapped during the first week will be below normal, thus making it desirable to leave the traps on the same hives rather than shifting them to different hives in the apiary. Colonies equipped with pollen traps will rear some brood but brood rearing will be curtailed. They may be given combs of pollen from other colonies to keep up their production, but good colonies at the beginning of the season will survive and may produce some honey. They can be united at the end of the season. Figure 6 shows a pollen tray, about two-thirds full of pollen, re moved from the trap. The pollen should be removed every 2 or 3 days under ordinary conditions and more often when the humidity is high or when the pollen is unusually moist. The pollen should be Spread out to a depth of to inch for air drying. To prevent molding, moist pollen can be dried rapidly in an improvised oven heated with electric light bulbs The oven may be constructed from a large fiber carton equipped with a rack to support five or six trays which consist of wooden rims covered with cheesecloth. The pollen should be Spread in a thin layer on the trays to allow the warm air which is generated at the bottom to pass through each tray and escape from an Opening in the top of the oven.

This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Honey bee (Apis mellifera) colonies were equipped with pollen traps obtained from the CC pollen company. One set of studies compared bee deaths and pesticide residues in pollen trap-treated colonies with untreated control colonies placed near agricultural fields that were sprayed with microencapsulated methyl parathion (Penncap-M®). A second set of studies examined the effect of the pollen traps on varroa mite (Varroa destructor) populations compared with mite populations in control colonies that were treated with the labeled chemical treatment for varroa mites. Pesticide Studies: The pesticide studies were in response to the problem of bee deaths due to poisoning by microencapsulated methyl parathion. The microcapsules are in the size range of pollen grains and poisoning became a problem in fruit orchards where the pesticide drifted onto blooming ground cover where it was accidentally collected along with pollen by foraging honey bees. The studies showed that the microencapsulated pesticide persisted on orchard ground cover (clover) for several days after the pesticide was sprayed. The pesticide was also in the pollen loads that were removed from foragers by the pollen traps, and in the bees that were dying as a result of the pesticide spray. The presence of the pollen traps did not significantly reduce bee deaths or pesticide residues in the treated colonies. The pesticide studies also showed that under drought conditions, blooming orchard ground cover plants such as clover may be sufficiently unattractive to foraging honey bees to prevent the expected pesticide poisoning that would normally occur after a Penncap-M® spray. In such cases drought may be an IPM tool for managing bee colonies in some potentially dangerous agricultural settings. Varroa mite studies: The varroa mite studies were in response to the enormous problem of the varroa mite parasite which, over the past twelve years, has killed virtually all feral honey bee colonies and reduced the nu.

This book was released on 2014 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Managed honey bee (Apis mellifera L.) colonies are important pollinators of many cultivated crops. Honey bee colony declines averaging 30% annually in the United States for the past 7 years have caused significant concern and hence have been a topic of intensive investigation. These declines are reportedly due to multiple factors. Poor nutrition, which may be a result of current migratory pollination practices, is one such factor. Migratory pollination is a common practice of beekeepers from the Pacific Northwest and involves the placement of managed honey bee colonies within a series of cropping systems. There is a gap in knowledge on how migratory pollination practices impact honey bee nutrition. To understand the potential impacts of migratory pollination on honey bee nutrition, it is critical to assess the diversity of pollen collected by bees when colonies are placed adjacent to these cropping systems. In this study, we describe the diversity of pollen collected by honey bee colonies managed by beekeepers in the Pacific Northwest region of the United States when placed in seven major cropping systems. We quantified the percent of target crop pollen and overall diversity of pollen collected by honey bees when colonies were placed in these cropping systems. We collected and identified pollen in almond (Prunus dulcis (Mill.)), cherry (Prunus avium L.), highbush blueberry (Vaccinium corymbosum L.), meadowfoam (Limnanthes alba Benth.), white clover (Trifolium repens L.), radish (Raphanus sativus L.), and carrot (Daucus carota (Hoffm.)) cropping systems. We found that pollen collected from colonies placed in almond cropping systems was predominately Prunus sp., and hence, low in pollen diversity. At the other end of the spectrum, pollen collected from colonies placed adjacent to blueberry cropping systems did not yield any target pollen types (Highbush blueberry, Vaccinium corymbosum L.), but was high in overall pollen diversity. The pollen collected from colonies placed in other cropping systems was largely intermediate in diversity between these two extremes. There were not many plant species in bloom when pollen was collected from colonies placed in almond cropping system, whereas more plants were in bloom when we collected pollen from colonies placed in blueberry cropping system. The results of this study demonstrate that honey bees collected pollen from plants in the surrounding environment and collected different degrees of pollen diversity across different cropping systems in which the colonies were placed. We further determined if pollen diversity influences colony-level protein utilization and biosynthesis of protein in nurse bees by conducting a pollen feeding experiment. Pollen collected from four different cropping systems in the first study was used to formulate four different diets, each varying in pollen diversity. We measured protein consumption in experimental colonies and by sampling nurse bees from each colony to estimate hypopharyngeal gland protein content and proteolytic enzyme activity after five weeks of feeding on the experimental pollen diets. Experimental colonies fed on pollen collected from almond cropping system exhibited a high protein consumption rate. However, low protein content as found in hypopharyngeal glands of nurse bees in these colonies. The nurse bees in these colonies also had low proteolytic enzyme activity, which indicates a lower rate of protein digestion. Overall, these results suggest that the diet representing pollen collected from almond cropping systems had low digestion rate and may have resulted in lower nurse bee hypopharyngeal gland protein. However, we cannot say this with certainty, as there were other confounding factors involved, such as presence of pesticides in the pollen collected from the cropping systems.
