Pollen Collection From Alsike Clover By High And Low Alfalfa Pollen Collecting Lines And By A Commercial Line Of Honey Bees, William P. Nye

All PIRU Publications

The collection of alsike clover pollen by high alfalfa pollen collecting (APe) and low alfalfa pollen collecting lines of honeybees and by bees from commercial colonies were compared at Donnelly, Idaho, U.S.A., in an area where alsike clover was flowering. All three lines collected an overwhelmingly high percentage of alsike clover pollen (92-99 %), and there were no significant differences between them. A limited amount of rape pollen was collected every day by all groups, and also a small amount of dandelion pollen on one or two days. Only one (high APC) colony collected pollen from a small nearby field …

Additional Studies On The Effect Of Field Applications Of Insecticides On Honey Bees, F. V. Lieberman, George E. Bohart, G. F. Knowlton, William P. Nye

All PIRU Publications

Choice of an insecticide treatment to be used on a legume seed crop in bloom should be determined by its hazard o bees as well as its economic effectiveness in controlling harmful insects. This is true not only because bees provide the cross-pollination essential to high yield of quality seed but also because most beekeepers still depend on a honey crop for their living.

In 1947 the staff of the U.S. Legume Seed Research Laboratory at Logan, Utah, initiated a study to ascertain which of the principal new organic insecticides could be applied to seed alfalfa in bloom without creating …

The Effect Of Field Applications Of Insecticides On Honey Bees, Frank E. Todd, F. V. Lieberman, William P. Nye, G. F. Knowlton

Reports of tests of new insecticides have tended to minimize the practical dangers to beekeeping when these toxicants are applied to crops in bloom. The idea is current that these insecticides are harmless to bees if applied during hours when bees are not on the field. An examination of one alfalfa-seed area, where bee losses from commercial applications were reported, prompted a more critical examination to determine the effect of field applications of these insecticides on bees. This paper is a report of field experiments near Logan. Utah, with early-morning applications of DDT, chlordane, parathion, and toxaphene to alfalfa in …
