Assessment Of Biodiversity On Mount Timpanogos With A Focus On Flies, Diptera: Agromyzidae, Samantha Smith, Dr. Riley Nelson
Assessment Of Biodiversity On Mount Timpanogos With A Focus On Flies, Diptera: Agromyzidae, Samantha Smith, Dr. Riley Nelson
Journal of Undergraduate Research
Mount Timpanogos, with an elevation of 3,582 meters, is home to an amazing array of insect species. Through much previous effort, many have studied the insects found in American Fork Canyon leading up to Mount Timpanogos. They have still barely scratched the surface of the abundant biodiversity on the mountain. Varied temperature regimes can cause changes in insects’ life cycle and the length of their feeding period, making the collections at different elevations of Mount Timpanogos during different years of particularly great value (Petitt et al 1991). Thus the value of collections along Mount Timpanogos is two-fold; both to study …
Bionomics Of A Subterranean Gall Midge (Diptera : Cecidomyiidae) From Artemisia Ludoviciana, Ranasinghe
Bionomics Of A Subterranean Gall Midge (Diptera : Cecidomyiidae) From Artemisia Ludoviciana, Ranasinghe
Theses and Dissertations
Bionomics of a gall midge that emerged from nodulelike structures of herbaceous sage, Artemisia ludoviciana Nutt., was studied as a part of a larger investigation on possible nitrogen fixation by this plant. Infested plants collected from the field were regularly examined in the laboratory where some of them were grown in a liquid nutrient medium. In the laboratory, adult midges were reared from the pupae and induction of infestation was attempted. Apparent nodulation on these plants is caused by the subterranean bud galls of a previously unknown gall midge species, Rhopalomyia subhumilis Gagne. The life history of this midge is …
The Population Dynamics Of Tanypus Stellatus Coquillett (Diptera: Chironomidae) In Goshen Bay Of Utah Lake, Dennis Kenji Shiozawa
The Population Dynamics Of Tanypus Stellatus Coquillett (Diptera: Chironomidae) In Goshen Bay Of Utah Lake, Dennis Kenji Shiozawa
Theses and Dissertations
The population dynamics of Tanypus stellatus in Goshen Bay of Utah Lake was investigated from July 18, 1973, to August 5, 1974. Samples were collected from three stations with an Ekman grab and a K-B corer. The samples were washed in a 110 micron nitex screen and then floated in a sucrose solution. The K-B core was used to determine the vertical distribution of Tanypus stellatus. Ninety-six percent of the Tanypus stellatus larvae are located in the top five centimeters; 99 percent are less than ten centimeters deep. The Ekman grab was used to study the population dynamics of the …
A Study Of Utah Phoridae Diptera, A. Lavell King
A Study Of Utah Phoridae Diptera, A. Lavell King
Theses and Dissertations
This study was undertaken to determine the present status in Utah of the Dipterous family Phoridae, and to report which genera and species are found there. The work was done with the thought in mind of furthering the knowledae of this little-known family in Utah. In order to secure information about the family the writer studied entomological literature and specimens obtained from the entomological collections of the Brigham Young University and Utah State Agricultural College. Personal collecting in various areas of Utah was also done. During the study it was found that there were six genera and twenty-one species correctly …
