Studies on Heterostylum robustum (Osten Sacken) (Diptera : Bombyliidae), a parasite of Nomia melanderi

Creator:: Eppley, Richard Keith
Abstract:: Heterostylum robustum (Osten Sacken) is the principal parasite of the alkali bee, Nomia melanderi Ckll., one of the most efficient pollinators of alfalfa in the western United States. The purpose of the study was to determine the incidence of parasitism and to investigate the biology of H. robustum. The fly...

Foraging and nesting behavior of the leaf-cutter bee Megachile rotundata (Fabricius)

Creator:: Osgood, Charles Edgar
Abstract:: The study provides the details of the ethology of Megachile rotundata (Fabricius), and presents preliminary observations on its foraging and nesting behavior. Development from prepupae to adults proceeds most rapidly at 32 degrees C., and is retarded when held at lower and higher temperatures. Male behavior is distinct from that...

Phospholipids of Tenebrio molitor larvae

Creator:: Kamienski, Francis Xavier
Abstract:: Phospholipids of Tenebrio molitor larvae were separated on columns of DEAE-cellulose and silicic acid-Hyflo Super Cel. The major phosphatide components were identified by various analytical procedures. Phosphatidyl choline was demonstrated to be the predominant phospholipid with a high percentage of phosphatidyl ethanolamine. A small amount of inositol-containing phosphatides were present....

The biology and behavior of the alkali bee Nomia melanderi Cockerell (Hymnoptera: Apoidea)

Creator:: Hackwell, Glenn Alfred
Abstract:: Nomia melanderi Cockerell is one of the most efficient pollinators of alfalfa in Eastern Oregon. Emergence begins in June, usually reaches its peak in early July, and may continue into early August. Male emergence precedes female emergence by four or five days. For the first few weeks of this time,...

Comparative embryology of Nomia melanderi, Megachile rotundata, and Bombus griseocollis (Hymenoptera:Apoidea)

Creator:: Hartman, Margaret Jane
Abstract:: Organogenesis was observed in different age embryos and first instar larvae of Nomia melanderi Cockerell (Halictidae), Megachile rotundata (Fabricius) (Megachilidae), and Bombus griseocollis (DeGeer) (Apidae) (Hymenoptera : Apoidea). It was found that, with the exception of the ventral nerve cord, comparable organ development had occurred by the beginning of the...

Circadian rhythms in Megachile rotundata (Fabricius)

Creator:: Tweedy, David Graham
Abstract:: The rhythms of emergence, oxygen consumption, and activity were studied in Megachile rotundata with the object of comparing the results to the major properties of the biological clock such as temperature independence, susceptibility to light synchronization, and entrainment. A further objective was to compare the three rhythms to determine if...

Immunoelectrophoretic techniques used for systematic investigation

Creator:: Lockwood, Lloyd James
Abstract:: Immunotaxonomic studies have largely been based on serology in which either one of two parameters has been used for establishing relationships: (1) the number of precipitin arcs formed on Ouehterlony plates, or (2) the total amount of precipitin resulting from reactions with a standard antiserum. Recognizing the restrictions of both...

Etiology and pathogenesis of chalkbrood in the alfalfa leafcutting bee, Megachile rotundata

Creator:: Vandenberg, J. D. (John Donald)
Abstract:: Chalkbrood is a mycosis of larvae of the alfalfa leafcutting bee, Megachile rotundata (Fabricius). It is a serious threat to alfalfa seed growers in western North America who use populations of this bee for pollination. Basic studies were conducted to determine the etiology of this disease and the course of...
