Distance From The Apiary As A Factor In Alfalfa Pollination, M. D. Levin, George E. Bohart, William P. Nye

All PIRU Publications

Experiments conducted in northern Utah indicated that the distribution of honey bees (Apis mellifera L.) on an alfalfa field is modified by various influences besides distance from the colonies. Because of these other factors, generalizations concerning the effect of distance from colonies on the distribution of foraging honey bees cannot be made on the basis of experiments herein reported. A slight negative relationship between bee populations and distance from colonies in alfalfa fields was found in some of the experiments reported. In two fields where the distance was less than 600 feet, horizontal stratification of the field population …

Descriptions, Biology, And Notes On The Identification Of Some Trogoderma Larvae, R. S. Beal Jr.

Ba

For several years members of the dermestid beetle genus Trogoderma have attracted widespread attention, particularly since T. granariurn Everts, the khapra beetle, became established as an introduced pest in Arizona, California, Mexico, and New Mexico. This species has been the object of a control program to remove it as a hazard to stored grain and to prevent its spread to parts of the country where it is not known to occur. Species of Trogoderma other than the khapra beetle may also build up to damaging numbers in stored products. Information has been obtained on these species, as well as on …

Some Aspects Of The Aspen-Birch-Spruce-Fir Type In Ontario, D.W. Maclean

Aspen Bibliography

The mixedwood types of the Boreal Forest in Ontario occupy sites that have a high potential for the production of spruce and fir. These types are commonly made up of various mixtures of trembling aspen, white birch, black spruce, white spruce, and balsam fir². In the unmanaged forest, this mixture of species usually results from fire, and the coniferous component is largely spruce. In the managed forest, fir rather than spruce is likely to be the main coniferous species in the next crop where measures are not employed to alter this trend in succession. This is a matter …

Economic Crop Alternatives For Dry Farm Areas Of Northern Utah, Earnest M. Morrison, Russell V. Withers

Utah Resources Series

Dry land farming is an essential part of the economy of northern Utah. With wheat in surplus production and subsequent crop controls a serious problem has developed in the area. The State Agricultural Statistician and the Agricultural Stabilization and Conservation Committee report that between thirty thousand and forty thousand acres have been taken from wheat production and are available for crops other than wheat.

A Morphological Description Of The Trichomonad Found In The Stomach Of Swine, Floyd M. Caskey

Biology

As far as is known, no morphological study of the stomach trichomonads of swine has been made. The majority of investigators have assumed that the trichomonads found in the cecum and stomach are identical. It has been reported that the nasal form is different from that of the cecum and that the nasal form is simlar to Trichomonas foetus. The relationships among the trichomonads from these three locations have yet to be determined.

Investigations In The Genus Chrysothamnus, Loran C. Anderson

Biology

The genus Chrysothamnus has long been noted for the great variation within its limits. More than eighty species have been technically described in this genus. In the nauseosus species complex as many as thirty-eight species have been named. An excellent morphological study of the group brought about the reduction of the number of recognized species to twelve with forty subspecies. In C. nauseosus variation has been so expressed by Hall: Nothing can be more certain than that these forty-two attemps to recognize species and varieties do not by any means exhaust the resources of the group. Every autumnal excursion into …

Studies Of Ultraviolet Inactivation Of Cucumber Mosaic Virus In Vivo, Twila Elaine Cheney

Biology

It has been known for some time that plant viruses are inactivated in vitro by ultraviolet (UV) irradiation (Arthur and Newell, 1929). The studies of Hollaender and Duggar (1936) and Price and Gowen (1937) have shown that tobacco mosaic virus (TMV) is inactivated in vitro according to a simple exponential law suggestive of a "one hit" process. More recently plant viruses have been inactivated in vivo by UV irradiation. Bawden and Kleczkowski (1955) found that the development of virus-induced lesions on French bean leaves could be wholly or partially inhibited by UV irradiation subsequent to inoculation with Rothamsted tobacco necrosis …

Comparison Of The Influence Of 17-Hydrocortisone And 2-Methyl 9a-Fluorohydrocortisone Acetate On The Involution Of The Thymus Gland In Mice, Gerald K. Wallace

Biology

Previous studies have shown that the adrenal cortical hormones play an important part in lymphatic tissues physiology. Several authors have demonstrated alterations in blood leukocytes and decreased thymus weight following administration of extracts or purified preparations of adrenal cortical hormones. For this reason the thymus gland weight and lymphocyte response have been used as a method of determining activity of several of the corticoids.

The Influence Of An Artificial Medium Upon The Morphology Of Swine Cecal Trichomonads, Charles P. Hibler

Biology

As yet no thorough studies of the trichomonads living in the cecum of swine have been made. In fresh preparations the trichomonads from the nose, stomach, and cecum appear distinct. After a period of cultivation In an artificial medium, however, the flagellates from the cecum became morphologically similar to the cultured porcine nasal and stomach trichomonads. The cultivation of the trichomonads from the cecum apparently results in either a morphological change in the trichomonad or in a selection among different species or types present in the cecum.
