Cuterebra (Diptera: Cuterebridae) Of Utah And The Neighboring States, Charles L. Graham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cuterebra are robust flies, which in flight resemble large black bees. Little is known about the bionomics of most of the species included in this genus. Nearly all members of this group parasitize rodents and lagomorphs. Some species have a wide host range, others seem to be specific or semi-specific to a single host. Accidental parasitism of animals other than specific host animals does occur. In such cases the larvae or the host usually die before the larvae can mature. There is a wide variation in the effect of of the parasite on its host. If the parasite is found …

A Revisional Study Of The Bees Of The Genus Perdita F. Smith, With Special Reference To The Fauna Of The Pacific Coast (Hymenoptera, Apoidea) Part V, P. H. Timberlake

All PIRU Publications

In parts III and IV of this revision the species of the typical subgenus of Perdita belonging in the zonalis, halictoides, and octomaculata groups have been treated. This study is now extended to include the species belonging in that section of Perdita which may be called the ventralis group. In order to facilitate the study of these bees a key to the groups treated in Part III and subsequent parts is here offered. This key may afford some help in classifying the more typical members of the groups, but because of the multiplicity and extreme diversity of these …

Observations On The Behavior Of Bees In A Controlled-Environment Room, William P. Nye

All PIRU Publications

A detailed description is given of a controlled-environment flight room for the study of bee behaviour both in and outside the colony. Experiments demonstrated the ability of a colony to collect pollen, sugar syrup and water in the room, and to rear brood normally, increasing its strength throughout It months in spring. The behaviour of bees collecting powdered pollen from a tray 30 ft. [10 m.l from the hive was influenced by the amount and distribution of light in the room.

Alfalfa Seed Production Studies, M. W. Pedersen, William P. Nye

All PIRU Publications

From a practical standpoint, the culture to use is the one that gives the greatest net return. The study indicates that planting alfalfa for seed production in 24-inch rows at a rate of 1.5 pounds of seed per acre and thinning in the fall of the year after planting is best. For example, a field planted in the spring of 1963 should be thinned in the fall of 1964. Cutting out approximately every other foot within the row seems advisable. While there appears to be considerable latitude in the extent of thinning, weed problems are encountered if the stand is …

Webworm And The Weather, J A. Button

Journal of the Department of Agriculture, Western Australia, Series 4

FOR many years farmers have remarked on the cyclic occurrence of webworm outbreaks in their cereal crops.

Webworm, the State's most serious pest of cereals, has frequently assumed a role of major importance for one or two seasons, and then not been troublesome for a number of years.

A research programme being carried out by the Entomology Branch aims to give a better understanding of the effects of weather conditions on the seasonal incidence of webworm, and should lead to more effective control of this pest.

Nectar Sugar Concentration As A Measure Of Pollination Of Alfalfa (Medicago Sativa L.), William P. Nye, M. W. Pedersen

All PIRU Publications

The "visitation rate of honeybees on alfalfa may possibly be measured by determining the sugar concentration of nectar in the honey stomachs of foraging bees. This concentration is shown to be largely controlled by the relative humidity and the time available for nectar evaporation in the alfalfa blossom, which in turn depends on the rate of visitation by honeybees. An adjustment for relative humidity may be necessary in order to compare readings widely separated in time or location. Where conditions are relatively constant from day to day, it may be sufficient to measure the nectar sugar concentration and relative humidity …

Management Of Honeybee Colonies For Pollination In Cages, William P. Nye

All PIRU Publications

The use of bees for pollination is extending in various directions, and each extension brings with it new problems to be solved. Infields and orchards, the main problem may be to get the bees to visit all the flowers. In a small plot, this can be ensured by enclosing the plot and a hive of bees in a cage, but special steps are then needed to ensure the well-being of the bees. In this article Mr. Nye, who is on the staff of the Entomology Research Division of the United States Department of Agriculture, describes the colony management necessary. The …

Some Experiments In Citrus Red Scale Control, G D. Rimes

Journal of the Department of Agriculture, Western Australia, Series 4

THE red scale (Aonidiella aurantii Masc.) is widely distributed throughout the world but tends to be a serious pest in those countries with semi-arid climates such as California, South Africa, Palestine and Australia.

The home of the pest is probably China, but it has been known in Australia for over 70 years and it was from the continent that it was introduced into North America.

An Unusual Tick Fever Outbreak, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

EARLY in the summer of 1961 there was a series of unusual tick fever outbreaks on several poultry farms in the metropolitan area.

These outbreaks were unusual because no apparent vector (disease carrier) could be found.

Mulesing And Tailstripping : For The Prevention Of Fly-Strike, W L. Mcgarry

Journal of the Department of Agriculture, Western Australia, Series 4

MULESING and tailstripping are basic to fly strike control.

During emergencies and bad fly waves they may need to be supplemented by temporary protective measures such as jetting and crutching.

Insect Pests Of Forests. 2. Tussock Moths And Bag-Shelter Moths, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

TWO native caterpillars which sometimes attract attention are the larvae of the tnssock moth and the bag-shelter moth.

Neither insect is a serious forest pest in Western Australia, but the tussock moth sometimes does restricted damage in orchards and home gardens and the bag-shelter caterpillars cause some defoliation of wattles and eucalyptus.

A Middle Miocene Rhinoceros Quarry In Morrill County, Nebraska (With Notes On Hip Disease In Diceratherium), Robert M. Stecher, C. Bertrand Schultz, Lloyd G. Tanner

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

Extensive deposits of fossil rhinoceros bones have been excavated from University of Nebraska State Museum collecting localities Mo-113, -114, -115, -116, and -118 some 8 1/2 to 9 1/2 miles north of Bridgeport, Morrill County, Nebraska. The fossils were associated with other faunal elements in the lower portion of the Marsland formation (middle Miocene) of the Hemingford group. The rhinoceros is considered to be Diceratherium niobrarensis Peterson, geologic variety. A pathologic right femur of D. niobrarensis provides evidence of hip disease in the medial Miocene rhinoceroses.

Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr.

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

Ten species of Recent mammals that formerly occurred in Nebraska have been extirpated there by European man. Surprisingly few specimens of the species concerned are preserved in museum collections. Perusal of a representative segment of the historical literature pertaining to Nebraska has revealed records of occurrence of most of the extirpated species that provide a basis for estimating the former distribution of each in the State.

A Comparative Study Of The Axillary Sclerites In Coleoptera, Howard P. Shurtleff

Theses and Dissertations

The axillary sclerites of 69 species representing 52 families of the order Coleoptera were examined and illustrations prepared of most or them. A description is given for the typical axillary sclerites and the deviations in form from this pattern are discussed for the major groups of beetles. The phylogenetic relationships between some families, and other groups, are pointed out based on the morphology of the axillary sclerites. Phyletic groups in Adephaga are characterized by the axillary sclerites, but in the Polyphaga variations are too numerous and inconsistant to be useful in determining phyletic trends.

Oviposition Response Of The Army Cutworm, Chorizagrotis Auxiliaris, To Different Media, K. P. Pruess

Department of Entomology: Faculty Publications

Moths of the army cutworm, Chorizagrotis auxiliaris (Grote), (Lepidoptera: Noctuidae) responded ovipositionally to differences in soil color, texture, and depth. Number of eggs laid increased with amount of light reflected. A combination of loose surface over a solid substrate was required. A light-colored sand fulfilled all requirements and was preferred over soil. Soil was acceptable when a loose surface of correct depth was provided. Solid surfaces were refused.

Distribution Of Army Cutworm Larvae In Wheat And Barley Fields, K. P. Pruess

Department of Entomology: Faculty Publications

Populations of the army cutworm, Chorizagrotis auxiliaris (Grote), tended to be higher in winter barley than winter wheat planted side by side in the same field. Highest populations occurred in barley within 30 feet of the adjoining wheat. Distribution of larvae in linear 1-foot samples agreed closely with the Poisson. Practical application of these results are discussed.

Successful Commercial Beekeeping, R S. Coleman

Journal of the Department of Agriculture, Western Australia, Series 4

THE eye of the master fattens the cattle. One of the oldest farming proverbs this is as true of bee-keeping as any other branch of farming.

Careful husbandry is the basis of all successful bee-keeping; anything else is secondary.

The House Fly (Musca Domestica), Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

MANY insects are so commonly associated with man and his dwellings that they may almost be called domesticated.

In olden days the presence of these insects was accepted as a matter of course, but present knowledge shows that many of them can be important disease carriers while others may cause damage to food and clothing.

Insect Pests And Their Control, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

METHODS of insect control are sometimes classified under the following four headings— Quarantine, Cultural Methods, Biological Control and Chemical Treatments.

Each method has its own particular part to play in preventing the spread and multiplication of insect pests and it is essential for maximum results that everyone— whether he be a commercial grower or a backyard gardener—has a general understanding of the principles involved.
