The Effect Of Imidacloprid On Honey Bee Queen Fecundity, Jamilyn Martin, Julia D. Fine, Amy Cash-Ahmed, Gene E. Robinson

PRECS 2018

Imidacloprid is a neonicotinoid insecticide commonly used in agricultural settings to control insect pests by acting as an agonist of acetylcholine receptors and inducing paralysis and mortality. In small doses, imidacloprid can cause loss of memory and foraging ability along with impaired learning and a lowered immune response in western honey bees (Apis mellifera). Effects of neonicotinoid insecticides on colony reproduction have been documented including decreased colony expansion, queen failure and replacement, and decreased queen egg laying.

For this study, we examined the effects of imidacloprid on the fecundity of queen bees when their worker attendants were exposed to low …

The Effects Of Forest Age And Management On Bee Communities Of Production Forests In The Southern United States, Robinson Sudan

LSU New Orleans Theses and Dissertations

Processes structuring bee communities in agricultural landscapes are well-documented compared to those in other anthropogenic landscapes, like production forests. Forests across the temperate zone have historically been under-sampled, in part due to the perception that they provide little habitat to support diverse bee communities. While research suggests that early successional habitats support high levels of bee species richness and abundance, little empirical evidence exists to support the notion that forests, in turn, do not. To understand the relationship between forest successional age and major elements of the bee community, I sampled bees in a southern production pine forest in Hancock …

Export Of Insect Ecosystem Services From Hayed Native Prairie, Wayne J. Ohnesorg

Department of Entomology: Dissertations, Theses, and Student Research

Natural areas, such as prairie, have the potential to provide the benefits of pest suppression and pollination for agricultural production. In Nebraska, prairie is often used for hay production. The impact of prairie hay production management practices on beneficial arthropods is not well understood. Four prairie hay meadows adjacent to row crop fields were selected in northeast Nebraska. The goal was to assess the impact of haying them on beneficial arthropods and the movement of natural enemies into adjacent crop fields. Three management practices were evaluated for hay harvested from prairie meadows one cut per growing season, two cuts per …

Population Genetics, Distributions And Phenology Of Bombus Latreille, 1802 And Xylocopa Latreille, 1802 (Hymenoptera: Apidae), Amber Dawn Tripodi

Graduate Theses and Dissertations

This work addresses multiple knowledge gaps in bee ecology, population health and phylogeography in order to provide insights into the changing distributions of native bees. A comparison of Arkansas bumble bee records mirrors range-wide surveys, with records of stable species (Bombus bimaculatus Cresson, 1863 and B. impatiens Cresson, 1863) increasing three-fold, and records of the declining B. pensylvanicus (DeGeer, 1773) dropping to 60% of historical levels. However, nationally-recommended conservation-genetics tools did not mirror these results on a regional level. Stable and declining species had equivalent genetic diversity in samples from Arkansas and Tennessee (H_S range: 0.46-0.63). Diploid males, …

Understanding How Honey Bee Flight And Senescence Are Connected Through Oxidative Stress., Joseph Margotta

UNLV Theses, Dissertations, Professional Papers, and Capstones

The goal of this dissertation was to exploit the tractability of the honey bee (Apis mellifera) to understand how the physiological and cellular mechanisms that determine the onset and duration of senescence are shaped by behavioral development and behavioral intensity. These data reveal how behavior can damage cells and consequently limit lifespan. The honey bee represents the ideal model to address these factors because age, behavior, functional senescence, and lifespan are easily manipulated independently of each other while in its natural environment. I determined if there was a cause-effect relationship between honey bee flight and oxidative stress by comparing damage …

Corpse Management In Social Insects, Qian Sun, Xuguo Zhou

Entomology Faculty Publications

Undertaking behavior is an essential adaptation to social life that is critical for colony hygiene in enclosed nests. Social insects dispose of dead individuals in various fashions to prevent further contact between corpses and living members in a colony. Focusing on three groups of eusocial insects (bees, ants, and termites) in two phylogenetically distant orders (Hymenoptera and Isoptera), we review mechanisms of death recognition, convergent and divergent behavioral responses toward dead individuals, and undertaking task allocation from the perspective of division of labor. Distinctly different solutions (e.g., corpse removal, burial and cannibalism) have evolved, independently, in the holometabolous hymenopterans and …

Quantification Of Pollinating Insects Of The Superfamily Apoidea In Three Ecological Niches Of Three Communities In The Municipality Of Coroico-Nor Yungas, Department Of La Paz, Óscar Jaime Claros Sossa

Theses and Dissertations

The superfamily Apoidea (commonly referred to as bees), are insects whose diet consists of the nectar and pollen from flowering plants. Therefore, they are essential pollinators of many species, both wild and cultivated.
Bees are similar to other Hymenoptera in appearance, size, and color variety. The superfamily Apoidea contains 17,000 known species and could possibly contain up to 30,000. Bees perform many tasks that benefit humanity such as pollinating the flowers of both wild and cultivated plants. Without this work, fruits and seeds necessary for the survival of different species, for our own food supply, and for industry would not …

Effects Of Flight Behaviour On Body Temperature And Kinematics During Inter-Male Mate Competition In The Solitary Desert Bee Centris Pallida, Stephen P. Roberts

Biological Sciences Faculty Research & Creative Works

Body Temperatures and Kinematics Are Measured for Male Centris Pallida Bees Engaged in a Variety of Flight Behaviors (Hovering, Patrolling, Pursuit) at a Nest Aggregation Site in the Sonoran Desert. the Aim of the Study is to Test for Evidence of Thermoregulatory Variation in Convective Heat Loss and Metabolic Heat Production and to Assess the Mechanisms of Acceleration and Forward Flight in Field Conditions. Patrolling Males Have Slightly (1-3°C) Cooler Body Temperatures Than Hoverers, Despite Similar Wingbeat Frequencies and Larger Body Masses, suggesting that Convective Heat Loss is Likely to Be Greater during Patrolling Flight Than during Hovering. Comparisons of …

The Bees Of Curlew Valley (Utah And Idaho), George E. Bohart, G. F. Knowlton

All PIRU Publications

In America north of Mexico there are an estimated 4,000 species of bees distributed in approximately 110 genera. In Curlew Valley, 132 species in 33 genera have been identified, and approximately 25 additional unidentified species have been collected. It is likely that at least 225 species in 40 genera should be found eventually. The bee fauna of Curlew Valley can be roughly divided into the following 4 categories on a seasonal basis.

Management Of Habitats For Wild Bees, George E. Bohart

All PIRU Publications

The North American Bee Fauna is composed of over 5,000 species, most of which are nonsocial and make nest burrows in the soil. About 500 species nest above ground in small cavities such as beetle holes, hollow stems and rock pockets or dig their own tunnels in pithy stems or wood. Also, about 100 social species (bumble bees, stingless bees, and the honey bee) establish their colonies in relatively large cavities, both below and above ground.

The honey bee (Apis mellifera L.) was brought to the New World by European colonists. Consequently, on this continent, it had no influence …

Introduction Of Small Carpenter Bees Into California For Pollination 1. Release Of Pithitis Smaragdula, Howell V. Daly, George E. Bohart, Robbin W. Thorp

All PIRU Publications

Pithitis smaragdula (F.) is a bright green, small carpenter bee which is widespread in the oriental region and is known to pollinate economically important plants, especially legumes and cucurbits. About 300 bees imported from Ludhiana, India, were released 10 April 1969, at Davis, California. Subsequent collecting during the 1st season confirmed that one or more generations of the bees had been reared and that Trifolium repens L. was visited for pollen. Although the overwintering bees under observation died from unknown causes, and no living bees were found in 1970, it is possible that the bees survived elsewhere. Ecological factors believed …

The Evolution Of Parasitism Among Bees, George E. Bohart

Faculty Honor Lectures

Before discussing parasitic bees, I will present a rough outline of the biology of "ordinary" or non-parasitic bees. The superfamily Apoidea (bees) includes perhaps 25,000 or 30,000 species divided into nine families by recent authorities (Stephen, Bohart, Torchio, 1969) . A common biological thread holding this vast assemblage together is the provision by adults of pollen and nectar for their young. Only in the honey bees (the genus Apis which includes four species) are the larvae fed primarily on a different substance (a secretion of the pharyngeal glands) , and even this is derived from pollen and honey eaten by …

A Revisional Study Of The Bees Of The Genus Perdita F. Smith, With Special Reference To The Fauna Of The Pacific Coast (Hymenoptera, Apoidea) Part V, P. H. Timberlake

All PIRU Publications

In parts III and IV of this revision the species of the typical subgenus of Perdita belonging in the zonalis, halictoides, and octomaculata groups have been treated. This study is now extended to include the species belonging in that section of Perdita which may be called the ventralis group. In order to facilitate the study of these bees a key to the groups treated in Part III and subsequent parts is here offered. This key may afford some help in classifying the more typical members of the groups, but because of the multiplicity and extreme diversity of these …

Observations On The Behavior Of Bees In A Controlled-Environment Room, William P. Nye

All PIRU Publications

A detailed description is given of a controlled-environment flight room for the study of bee behaviour both in and outside the colony. Experiments demonstrated the ability of a colony to collect pollen, sugar syrup and water in the room, and to rear brood normally, increasing its strength throughout It months in spring. The behaviour of bees collecting powdered pollen from a tray 30 ft. [10 m.l from the hive was influenced by the amount and distribution of light in the room.
