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,...

A survey of alfalfa pollinators and polination in the San Joaquin Valley of California with emphasis on establishment of the alkali bee

Creator:: Torchio, Philip F.
Abstract:: The study involves the establishment, management, and behavioral observations of Nomia melanderi Cockerell and Megachile rotundata (Fabricius) in California, a survey of native bees within western Fresno County, a determination of selfing and/or parthenocarpy in two fields of alfalfa, and observations on the honeybee as an alfalfa pollinator. The alkali...

Effects of synthetic 9-oxodectrans-2-enoic acid on the foraging activities of honey bees (Apis mellifera L.)

Creator:: Youngs, Lorna C.
Abstract:: An experimental formulation of 9 -oxodec-trans-2-enoic acid, the major component of honey bee (Apis mellifera L.) queen pheromone, was tested for its effect on worker foraging behavior in the pollination of sweet cherries (Prunus avium L. ). The test formulation consisted of a solid beeswax cylinder impregnated with a measured...

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...

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...

Mechanisms of orientation in the leaf-cutter bee Megachile rotundata (Fabricius)

Creator:: Osgood, Charles Edgar
Abstract:: The leaf- cutter bee Megachile rotundata (Fabricius) is an important alfalfa pollinator in western North America. This study was designed to provide information on methods of orientation used by M. rotundata in order to make recommendations regarding the parameters within which adult nesting populations may be relocated. Preliminary studies suggest...

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...

Pollination and pollinators of pumpkin and squash (Cucurbita maxima Duchesne) grown for seed production in the Willamette Valley of western Oregon

Creator:: Gavilánez-Slone, Jenny M.
Abstract:: 'Golden Delicious' winter squash (GDWS), Cucurbita maxima Duchesne, provides significant amounts of pollen (24 mg) and nectar (236 μl), but with a low reward of 14% nectar sugar. The quantity of nectar produced per GDWS flower differed between sites and floral sex. The GDWS male flowers had 25% higher sugar...

Scent-making by nectar collecting honey bees

Creator:: Wetherwax, Peter B.
Abstract:: Honey bees mark artificial flowers with scents that advertise about the previous history of the flower to subsequent foragers. Unrewarding flowers are marked with a scent, after a single visit, that makes the flower less attractive to subsequent foragers. Previously rewarding flowers are initially less attractive than unvisited flowers but...
