Behavior Patterns Of The Adult Alfalfa Weevil In Cache Valley, Utah, J. Wanless Southwick May 1966

Behavior Patterns Of The Adult Alfalfa Weevil In Cache Valley, Utah, J. Wanless Southwick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The alfalfa weevil, Hypera postica (Gyllenhal), was first found in the United States in Salt Lake City, Utah, during 1904 (Titus, 1910b). It spread form this point of original introduction and partially infested Cache Valley by 1912 (Titus, 1913).


Susceptibility Of Selected Alfalfa Clones To Lygus Bugs In Relationship To Seed Production, Charles G. Summers May 1966

Susceptibility Of Selected Alfalfa Clones To Lygus Bugs In Relationship To Seed Production, Charles G. Summers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah ranks as one of the major producers of alfalfa seed in the nation. In 1964, 6.02 million pounds of cleaned seed were produced in the state. This resulted in an income of 1.7 million dollars to Utah seed producers for that year (Agricultural Statistics, 1965).

Melathion, Naled, Fenthion, And Bayer 39007 Thermal Fogs For Control Of The Stable Fly, Gary A. Mount, C. S. Lofgren, James B. Gahan Jan 1966

Melathion, Naled, Fenthion, And Bayer 39007 Thermal Fogs For Control Of The Stable Fly, Gary A. Mount, C. S. Lofgren, James B. Gahan

Entomology Papers from Other Sources

The stable fly, Stomoxys calcitrans (L.), or dog fly, as it is commonly called in northwest Florida, has been a serious nuisance in that area for many years. Blakeslee (1945) found that DDT gave effective control when it was applied as a residual spray to larval breeding areas in marine grass deposits. However, in recent years this method has not provided the degree of control necessary. As a result, large numbers of adult flies have at times seriously affected the tourist industry of northwest Florida. On the basis of our work, and that of others, with thermal fogs for mosquito …

Organo-Phosphorus Insecticides For Control Of Red-Legged Earth Mite And Lucerne Flea, J A. Button

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

MOUNTING CONCERN over residue problems arising from the use of D.D.T. and other chlorinated hydrocarbon insecticides on pasture has highlighted the need for alternative chemicals capable of providing satisfactory control without undesirable side effects.


Citrus Red Scale Control, G D. Rimes Jan 1966

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 and is a serious pest in 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 introduced into North America from the continent.


Did This Cause This? [Sarcoptic Mange Of Pigs], F C. Wilkinson Jan 1966

Did This Cause This? [Sarcoptic Mange Of Pigs], F C. Wilkinson

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

The mite on the left was detected by using a microscope with a magnification of 100 times to examine a skin scraping taken from the above pig.

This confirmed the suspicion that sarcoptic mange mites were the cause of the skin lesions.


Termites Or White Ants, Clee Francis Howard Jenkins Jan 1966

Termites Or White Ants, Clee Francis Howard Jenkins

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

TERMITES are commonly but erroneously called "white ants."

Actually they are more nearly related to cockroaches than to ants, but their general appearance and subterranean habits have given strong support to the popular designation.

They may be divided into two major groups from an economic point of view, viz., wood-dwelling and earth-dwelling termites.


Pheremones In Trailmaking, Roxanna Young Jan 1966

Pheremones In Trailmaking, Roxanna Young

Student Scholarship

The paper explores the complex systems of chemical communication utilized by insects, with a specific focus on the role of pheromones in the trailmaking behavior of foraging ants. Unlike hormones that act internally, pheromones are secreted externally to influence the behavior or physiology of other members of the same species. These substances are categorized into two functional groups: releaser pheromones, which trigger an immediate behavioral response via the central nervous system, and primer pheromones, which induce slower physiological changes in the recipient. 

Foraging in ant colonies typically involves a transition from exploratory scouting to organized trailing. When a scout discovers …


Is Your Farm A Haven For Grain Pests, Department Of Agriculture, Western Australia Jan 1966

Is Your Farm A Haven For Grain Pests, Department Of Agriculture, Western Australia

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

Overseas markets insist that the grain they buy must be in sound condition and free of insect pests.

Keep your farm free of stored grain pests and you will help to protect our export markets and reduce the cost of treatment that you and your neighbours will bear.


Early Spraying Esential For Webworm Control, J A. Button Jan 1966

Early Spraying Esential For Webworm Control, J A. Button

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

Results of trials conducted during the last two seasons have emphasised the need for very early treatment of webworm infested crops.

Where heavy infestations occur every effort should be made to apply treatments during the first fortnight after crop emergence

Chromogen-Ratio Method For Determining Digestibility Of Plants By Grasshoppers, E. A. Heinrichs, K. P. Pruess Jan 1966

Chromogen-Ratio Method For Determining Digestibility Of Plants By Grasshoppers, E. A. Heinrichs, K. P. Pruess

Department of Entomology: Faculty Publications

The concentration of plant pigments in excreta vs. food provided a measure of digestibility of most plants by grasshoppers. Digestibility values obtained with the chromogen-ratio method and consumption-excretion ratios were highly correlated (r = 0.789**). Greatly disparate results were obtained in 4 cases. The chromogen method, when applicable, gave better duplicability and eliminated many of the errors and much labor associated with consumption-excretion ratios.

Nocturnal Flights Of Triatoma Protracta (Uhler) As Indicated By Collections At Black Light Traps : (Hemiptera: Reduviidae: Triatominae), Robert D. Sjogren Jun 1965

Nocturnal Flights Of Triatoma Protracta (Uhler) As Indicated By Collections At Black Light Traps : (Hemiptera: Reduviidae: Triatominae), Robert D. Sjogren

Loma Linda University Electronic Theses, Dissertations & Projects

An investigation into the environmental and ethological factors relating to summer flights of Triatoma protracta protracta (Uhler) was performed utilizing black light traps of original design. Field observations were conducted on 51 evenings during the period June 1 to October 31, 1964. The traps were operated on a surveillance basis for the remainder of a twelve month period.

A total of 398 adult Triatoma protracta were collected in traps around a residence located in the chaparral covered foothills 10 miles east of Redlands, California. In addition to observations on field behavior, laboratory dissections were performed on each bug to obtain …
