The Biology Of Choristoneura Houstonana (Lepidoptera: Tortricidae), A Pest Of Juniperus Species, E. A. Heinrichs, Hugh E. Thompson

Department of Entomology: Faculty Publications

Choristoneura houstonana (Grote) lays eggs singly in July. Egg development ranged from 8 to 11 days, with the majority hatching 10 days after oviposition. Larvae are solitary, and mine during early instars, but later instars feed externally on leaves in shelters made by webbing foliage together. There is one generation each year, and overwintering occurs in a hibernaculum, in mined leaves. Field-collected head-capsule width frequencies indicated nine larval instars. Rearing larvae on seedling junipers indoors indicated a range of 8–11 instars. Pupation occurs during June and July in the shelter where the larva feeds. The pupal stage lasted about 10 …

Osteology And Myology Of Phrynosoma P. Platyrhinos Girard And Phrynosoma D. Hernandesi Girard, Richard L. Jenkins, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

This study confirms the work of Etheridge (1964) in suggesting the peculiarity of the genus Phrynosoma within the family Iguanidae. The anterior osteology and myology of Phrynosoma platyrhinos platyrhinos Girard and Phrynosoma douglassi hernandesi Girard indicate Phrynosoma to be highly specialized and to differ significantlv from the Iguanid structure as portrayed by Oelrich (1956), Robison and Tanner (1962), and Avery and Tanner (1964). They also differ because of: ( 1 ) absence of lacrimal and postfrontal bones; (2) occurrence of occipital (also mandibular and temporal) spines; (3) posterodorsal shift of the skull elements; (4) divided nature of the M. sternohyoideus, …

Biometrical Study Of Morphology And Development Of The Pennsylvanian Trilobite Ameura Sangamonensis (Meek And Worthen), Roger K. Pabian, J. A. Fagerstrom

Bulletin of the University of Nebraska State Museum (1924–2023)

Biometrical study of morphology and development in a sample of 100 cranidia, 94 pygidia, 26 free cheeks, and 9 complete specimens of the trilobite Ameura sangamonensis (Meek and Worthen) from the Bonner Springs Shale (Pennsylvanian; Missouri Series) in eastern Nebraska indicates that the dominant growth pattern was isometric. Evidence supporting this conclusion consists of rectilinear size relations among eight pairs of cranidial dimensions, three pairs of pygidial dimensions, and three pairs of dimensions of the free cheeks. Qualitative changes in pygidial morphology during development include a progressive decrease in prominence of the border, increasing width of the posterior border relative …

Some Aspects Of Carbohydrate Metabolism In The Cercariae Of Schistosoma Mansoni Sambon, 1907, A. Eugene Dunham Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

Cercariac of Schistosoma mansoni were studied for glycogen utilization, uptake of glucose from solution, lactic acid production, and respiration.

Using the anthrone method of determination of carbohydrate, the amount of glycogen used by a single cercaria in 4 hours is determined as 43.2 x 10^-4 μg ± 6.6 x 10^-4 μg.

Glucose was not observed to have been used from solution under the conditions of the experiment, even in the presence of trehalose. The determinations were made by the Glucostat method.

After deproteinization and desugarization, aliquots of supernatant from cercarial suspensions were analyzed for lactic acid using p-phenylphenol …

Concurrent Infections Of Schistosoma Mansoni And Trypanosoma Equiperdum In Mice, Venus Ee-Siriporn

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this investigation was to determine factors which may influence the survival time of mice infected with Trypanosoma equiperdum and the effects of T. equiperdum on mice infected with Schistosoma mansoni.

In order to maintain experimentally obtained standard hours of survival (88 hrs) in mice inoculated intraperitoneally with 150,000 T. equiperdum, it was found that trypanosomes removed from the donor rat should be kept at 25 C and all counts, dilutions of the organisms, and injection should be completed within 1 hour after removal from the donor host. Survival time of mice is increased as the …

A Study Of Alveolar Bone Loss And Two-Hour Postprandial Blood Sugar Levels, R. Leslie Arnett

Loma Linda University Electronic Theses, Dissertations & Projects

Two-hour postprandial blood sugar determinations were carried out on 500 patients referred for periodontal care. The mean percentage of alveolar bone loss around the mandibular bicuspid teeth was established for each individual. The subjects were then grouped according to blood sugar levels and the mean alveolar bone loss was calculated. The group was separated into male and female sub-groups and data was computed for these segments as well as the total sample. The data was evaluated in a similar manner for those subjects between 40 and 49 years of age.

No Chi-square determinations were statistically significant but significance in differences …

During the period from June, 1966, to September, 1967, 27 amphibians of two species, 446 reptiles of eight species, 561 birds of 81 species, and 4050 mammals of 26 species were examined for ectoparasites at the National Reactor Testing Station in southern Idaho. Of seven species of ticks collected, the predominant one was Ixodes kingi, found on mammals of 12 species. Next in abundance was Dermacentor andersoni found on birds of three species and mammals of 16 species. Haemaphysalis leporispalustris was taken from birds of 10 species and six spvecies of mammals. Four other species of Ixodes were taken from …

The Effect Of Cesium-123 On Cesium-137 Uptake By Tissues In The Laboratory Rat, Richard Riley Tokarz

Biology ETDs

The effects of stable cesium-133 on cesium-137 metabolism were studied to better define mechanisms of cesium transport and binding by rat tissues. The extent to which the hypothetical cesium transport system can be overloaded was examined by giving cesium-133 and cesium-137 intraperitoneal injections within short time intervals. Whole animal and isolated tissue counts were made with a small animal whole body counter. Stable cesium-133 (0.02 g per animal) injected from 3 minutes to 24 hours prior to cesium-137 (0.15 ml containing 0.24 µCi per 100 g body weight) had little effect on the uptake of cesium-137 by tissues. Expressing data …

Normal Development Of The Aortic Isthmus, Elizabeth Short

Yale Medicine Thesis Digital Library

The development of the aortic isthmus, that region of the arch of the aorta between the left subclavian artery and the attachment of the ligamentum arteriosum, has received little attention. While the developmental history of the ductus arteriosus and foramen ovale has been well documented, as have the cardiac malformations associated with failure to complete this developmental sequence, little work has been done to define the normal sequence of isthmus development in its transition to an adult configuration in the postnatal period. It has long been recognized that the cardiac malformation known as infantile or preductal coarctation of the aorta …

Studies Of Diet As A Factor In 137-Cesium Metabolism In Rats, Morris Burton Snipes

Biology ETDs

Effects of diet on ¹³⁷Cs retention and distribution in the rat were examined. After a 7-day period, retention of an intraperitoneal dose of ¹³⁷Cs was higher than control values for rats fed semistarvation, high carbohydrate, high protein, and high fat diets. Relative distribution of ¹³⁷Cs among tissues .was examined considering changes in tissue composition due to diet variation. The primary effect of diet on cesium metabolism was a modification of cesium excretion via urine and feces. There appeared to be a direct relationship between mass of fecal material and the amount of ¹³⁷Cs excreted in feces. …

Geographical Variation Of The Apache Pocket Mouse In New Mexico, Daniel F. Williams

Biology ETDs

The geographic variation of Perognathus apache Merriam in New Mexico was investigated to determine the relationship of P. apache to P. flavescens Merriam and the relationships of the subspecies of P. apache to each other. Skin and skull measurements of adult specimens were analyzed statistically. Relative color values for adult specimens were estimated by selecting two individuals as color standards and comparing the other specimens with the standards. Apache pocket mice from southwestern New Mexico were found to be closer in size and proportions to the smaller P. flavescens from eastern New Mexico than to the larger Apache pocket mice …

A Comparative Food Habit Study Of Two Species Of Kangaroo Rats - Dipodomys Ordi And Dipodomys Merriami, Marilyn Kobylack Dunham

Biology ETDs

The present study was undertaken to investigate the food habits in two species of kangaroo rats, Dipodomys ordi Woodhouse and Dipodomys merriami Mearns, by comparing the seeds that they store in their cheek pouches. Since both species of kangaroo rat occur sympatrically at many places in the Southwest, Gennaro (1966) has concluded that interspecific competition with D. ordi might serve to limit the northern distribution of D. merriami in the Rio Grande Valley of New Mexico. The nature of this interspecific relationship was investigated through a comparison of the seeds of both species.

Investigations have revealed that there is a …

Behavioral Changes In Ants During Radiation Exposure, Niel Henry Milton Berg

Biology ETDs

There are only a few reports concerning the response of ants to irradiation and the majority of these are based on unpublished work. Apparent misinterpretations regarding the avoidance by ants of irradiation have occurred because of confusion as to dose, dose rate, and the type of radiation used. The only apparent demonstration of ant avoidance to radiation was made using x-rays at dose rates of 50-70 r/sec, although one author cites evidence for an ant avoidance response to 10 r/hr of 137Cs gamma rays.

In the present study, queen ants of the genus Pogonomyrmex, and worker ants of the species …
