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, 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 insects. This …

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 …

Honey Bees’ Impact On The U.S. Economy, James T. Chisel

Economics Theses

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, Mohamed Abdulla Al Muhairi

Theses

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.), 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 distance moved at all dose …

Research Into Western Australian Honeys, Robert J G Manning

All other publications

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 …
