Bee Abundance Along a Tropical Montane Elevational Gradient and Implications for Crop Pollination Services
… are important pollinators for my focal crop species, as they represent approximately 75% of the pollinators visiting both P. americana and C. pepo; however, species accumulation curves indicate the need for additional sampling in order to accurately determine the entire pollinator …

An Assessment of Non-Apis Bees as Fruit and Vegetable Crop Pollinators in Southwest Virginia
… which documents the role of non-Apis bees in crop pollination in southwest Virginia. Major findings of this first study of its kind in the region were that non-Apis bees provided the majority of pollination—measured by visitation—for several economically important entomophilous crops (apple, …

Strawberries (Frag X Anan) Are Bigger When Native Mason Bees (Osmia lignaria) Are Experimentally Added to Small Farms
… is the cornerstone of our economy, and pollination plays a vital role in nearly all non-wind pollinated crops. Declining honey bee populations have caused a more diligent investigation into using solitary bees for crop pollination. The native, solitary Orchard Mason Bee has shown to …

Three Essays on the Economics of Agricultural Production Behavior, Renewable Natural Resources, and Welfare Dynamics
… * How do farmers decide whether to use managed pollination service markets, and are observed use patterns optimal? * Does the provision of index-based agricultural insurance lead to resource degradation, or improvement? Although on one level these topics are unrelated, the reality is that there …

The Effects of Pesticide Exposures on the Nutritional and Immune Health of the Honey Bee, Apis mellifera L.
The honey bee is a widely managed crop pollinator that provides the agricultural industry with the sustainability and economic viability needed to satisfy the food and fiber needs of our society. Excessive use of agrochemicals such as the acaricides coumaphos and tau-fluvalinate, and the fungicide, …

Exploring strategies to enhance pollination and yield in the field bean, Vicia faba L.
<i>Vicia faba</i> is a legume crop valued for its high protein content and ability to fix nitrogen. The UK is a key producer of faba beans, which are likely to be increasingly important as a less environmentally harmful protein source. However, without insect pollination, <i>V. faba</i> yield …

Bee-cause - Designing to receive: a project which explores designing landform and soils to receive and support a variety of flowering species in strategically located corridors; bridging the boundary between the cape honey bee foraging grounds and bee pollinated farmlands, as a result creating other socioeconomic, educational and environmental relationships
… analysis might have overlooked. The process of crop pollination by Cape honey bees (Apis mellifera capensis). The study found that although no physical conventional barrier stops the bees from flying into the desired agricultural land from their more permanent foraging grounds, they are …

Elucidating the molecular basis of dihydroxyacetone (DHA) production in Leptospermum nectar
… Despite the fundamental importance of nectar to crop pollination and honey industries, the genetic control of nectary function is poorly understood, especially in non-model species. This thesis aims to elucidate the molecular basis of DHA production in Leptospermum nectar, through identifying …

Ecosystem services provided by native New Zealand plants in vineyards
… ecosystem services, either around arable crop borders or within vineyards. For CBC enhancement around crop borders, the shrub Muehlenbeckia astonii Petrie (Polygonaceae) may improve the management of the brassica (Brassica spp.) pest Plutella xylostella L. (Lepidoptera: Plutellidae) as the …
