The Genus Agastache As Bee Forage: An Analysis Of Reader Returns, George S. Ayers, Mark P. Widrlechner
Mark P. Widrlechner
In the May column, we reviewed published reports on the genus Agastache3 as bee forage and came to two somewhat contradictory conclusions: 1. The data support the contention that under proper circumstances several species of Agastache can be exceptional bee forage. These data came from observations made on both wild (Pellett, 1926; Vansell, 1933; and Wilson et al., 1958) and cultivated plants (Terry, 1872; Pellett, 1943 and 1946; and Mayer et al., 1982). 2. Despite Agastache's potential productivity and the fact that there were two historical periods in which one or more members of the genus were cultilvated for ...

Why We Still Need To Worry About Bees, 2016 Cuny Graduate School of Journalism
Why We Still Need To Worry About Bees, Meaghan Lee Callaghan
American honey bees, and other native bee species, are still in decline, though the specter of colony collapse disorder may be fading behind us. Colony decline, the loss of bees overwinter experienced across the country at a quarter to third lost per hive (sometimes more), is now expected. Losses can include those from colony collapse disorder. The author discusses the different causes for colony decline and speaks to bee health scientists and local beekeepers.

Soil-Water Transport Of A Seed Coated Neonicotinoid Pesticide In Soybean/Maize Cultivation Systems, 2016 University of Tennessee, Knoxville
Soil-Water Transport Of A Seed Coated Neonicotinoid Pesticide In Soybean/Maize Cultivation Systems, Geoffrey Nathaniel Duesterbeck
The current decline of the honey bee (Apis mellifera L.) and other beneficial pollinator species is well documented. Several causes have been cited in this decline including: pathogens, pests, nutrition, and pesticide exposure. Since the advent of the neonicotinoid family of pesticides in the 1990’s an increase in honey bee colony loss has been observed. Neonicotinoid pesticides are commonly applied as a seed treatment to cotton, soybean and maize row crops. As the seed germinates, it absorbs the pesticide from the coating then spreads systemically throughout the entire plant. However, a large portion of the seed coating may stay ...
A Plan For Pollinator Landscape Management On The Ursinus Campus, 2016 Ursinus College
A Plan For Pollinator Landscape Management On The Ursinus Campus, Megan N. Hanscom
Environmental Studies Honors Papers
Due to increased pollinator decline over the past decade, colleges and universities are developing pollinator management plans to help combat pollinator loss. Pollinators, and more specifically bees, are vital members of local ecosystems and protection efforts are greatly needed. This plan was created to address the needs of Ursinus College pollinators using relevant suggestions from pollinator research and existing protection plans. This plan includes suggestions for increased pollinator habitat on campus, ways to reduce pollinator stressors, and ways that the Ursinus community can positively impact pollinator health.
Ecological Risks Of The Conventional Insecticide/Fungicide Seed Treatment Mixture Of Thiamethoxam And Mefenoxam In Soybean On Beneficial Insects, 2016 University of Nebraska-Lincoln
Ecological Risks Of The Conventional Insecticide/Fungicide Seed Treatment Mixture Of Thiamethoxam And Mefenoxam In Soybean On Beneficial Insects, Carolina Camargo
Dissertations and Student Research in Entomology
The impact of neonicotinoid seed treatments on beneficial insects has been a controversial topic during the last years. While neonicotinoids are usually used as mixtures with systemic fungicides, few studies have examined the impact of the mixtures on beneficial insects. Pesticide mixtures can have synergistic, additive, or antagonistic effects on the toxicity of neonicotinoids on non-target species.
Thiamethoxam with mefenoxam is the most used neonicotinoid insecticide/fungicide mixture applied to soybean. Based on the systemic nature of thiamethoxam and mefenoxam, residues of this insecticide/fungicide mixture can be present in soybean vegetative and floral tissue with potential impacts to beneficial ...
The Enhancement Of Wild Bees (Hymenoptera: Apoidea) For Pollination Security, 2015 University of Maine
The Enhancement Of Wild Bees (Hymenoptera: Apoidea) For Pollination Security, Eric M. Venturini
Electronic Theses and Dissertations
The acreage of pollinator-dependent crops continues to expand across the globe. Simultaneously, honey bee hives – an annually rented commodity that growers rely on – are more expensive every year and in some cases, scarce. In response, pollinator-dependent growers seek alternative pollinators. One approach is installing bee pasture on farms, a strategy that enables systems-based farmers to become in-situ farm-scale habitat managers. This thesis first presents a review of the literature on bee pasture plantings and provides a brief overview of some methods for assessing their impacts on the pollinator community. There are three major gaps in current bee pasture research. First ...
Honey Bees’ Impact On The U.S. Economy, 2015 University of Puget Sound
Honey Bees’ Impact On The U.S. Economy, James T. Chisel
Since Colony Collapse Disorder became front-page news in 2006, popular literature ranging from news articles to White House documents has cited the value that honey bees provide. These numbers in articles often are inconsistent and rarely cite the origin of the stated value. This paper examines the major studies on the economic impact that honey bees have in the United States. Then it discusses the existing errors in these studies’ methodologies and offers a preliminary model that incorporates the full economic effects of honey bees. It then offers some policy suggestions in order to better address the needs of honey ...
Effect Of Abscisic Acid On The Growth And Development Of Lettuce (Lactuca Sativa 1.) Under Varied Irrigation Regimes, 2014 United Arab Emirates University
Effect Of Abscisic Acid On The Growth And Development Of Lettuce (Lactuca Sativa 1.) Under Varied Irrigation Regimes, Mohamed Abdulla Al Muhairi
Economically important vegetable crop lettuce (Lactuca sativa L.) of family Asteraceae was selected for the present investigation. It is being cultivated in UAE due to its commercial importance. In lettuce cultivation, major problem is the requirement of large quantity of irrigation water. The present study was aimed to reduce the water consumption of lettuce cultivation, for that, a varied irrigation regime was used with the application of abscisic acid (ABA). The parameters studied were growth, photosynthetic pigments, biochemical constituents, antioxidant potential and antioxidant enzymes activities in lettuce plants under drought stress and its response to ABA under stress. Drought stress ...

Using Video-Tracking To Assess Sublethal Effects Of Pesticides On Honey Bees (Apis Mellifera L.), 2012 University of Nebraska-Lincoln
Using Video-Tracking To Assess Sublethal Effects Of Pesticides On Honey Bees (Apis Mellifera L.), Bethany S. Teeters, Reed M. Johnson, Marion D. Ellis, Blair D. Siegfried
Faculty Publications: Department of Entomology
Concern about the role of pesticides in honey bee decline has highlighted the need to examine the effects of sublethal exposure on bee behaviors. The video-tracking system EthoVisionXT (Noldus Information Technologies) was used to measure the effects of sublethal exposure to tau-fluvalinate and imidacloprid on honey bee locomotion, interactions, and time spent near a food source over a 24-h observation period. Bees were either treated topically with 0.3, 1.5, and 3 μg tau-fluvalinate or exposed to 0.05, 0.5, 5.0, 50, and 500 ppb imidacloprid in a sugar agar cube. Tau-fluvalinate caused a significant reduction in ...

Research Into Western Australian Honeys, Robert J G Manning
Publications not in a series
On the 26 February 2002, the then Department of Agriculture released a media statement about the results of research conducted by Rob Manning and Nola Mercer about WA honeys’ antimicrobial activity using an assay developed in New Zealand. The research showed that Western Australian honey had some of the highest activity levels in the world due to a naturally occurring enzyme in the honey. Upon dilution of honey, the enzyme glucose oxidase produces low concentrations of hydrogen peroxide which is the source of its antimicrobial activity. It is different to Manuka (Leptospermum scoparium) honey from New Zealand which is termed ...
