Diversity And Abundance Of Insects From The Reduviidae And Pentatomidae Families In Three Ecological Niches Of Six Communities In The Coroico And Coripata Municipalities, Department Of La Paz, Fernando Miguel Manrique Mamani
Theses and Dissertations
The Hemiptera order has 23,000 species that are distributed among many families. Two of these are the Pentatomidae and Reduviidae families. The aim of this study was to identify the different species of insects from the Reduviidae and Pentatomidae families as well as each species’ abundance in three ecological niches (forest, forest edge, and farm land). The study was conducted in six communities of Los Yungas, La Paz (Carmen Pampa, San Pablo, San Juan de la Miel, Altuspata, Choro Alto, and Choro). In each community, three Malaise traps were installed in the three ecological niches (forest, forest edge, and farm …
Biodiversity Of Insects From The Syrphidae And Carabidae Families In Three Ecological Niches (Forest, Forest Boarder, And Farming Area) In Three Communities Of The Coroico Municipality, Nor Yungas, La Paz, Eddy Alarcón
Theses and Dissertations
Today, biodiversity is one of the most studied disciplines because it encompasses all species of plants, animals, and microorganisms that exist and act within an ecosystem. In recent decades, biodiversity has been degrading rapidly due to the simplification of agricultural systems, and the irrational use of pesticides that alter the normal function of ecosystems. Within nature, each insect population is attacked by one or more natural enemies. In this investigation, during a six month period from June to December 2006, the biodiversity of predatory insects from the syrphidae and carabidae families was determined in three ecological niches of three communities …
Quantification Of Pollinating Insects Of The Superfamily Apoidea In Three Ecological Niches Of Three Communities In The Municipality Of Coroico-Nor Yungas, Department Of La Paz, Óscar Jaime Claros Sossa
Quantification Of Pollinating Insects Of The Superfamily Apoidea In Three Ecological Niches Of Three Communities In The Municipality Of Coroico-Nor Yungas, Department Of La Paz, Óscar Jaime Claros Sossa
Theses and Dissertations
The superfamily Apoidea (commonly referred to as bees), are insects whose diet consists of the nectar and pollen from flowering plants. Therefore, they are essential pollinators of many species, both wild and cultivated.
Bees are similar to other Hymenoptera in appearance, size, and color variety. The superfamily Apoidea contains 17,000 known species and could possibly contain up to 30,000. Bees perform many tasks that benefit humanity such as pollinating the flowers of both wild and cultivated plants. Without this work, fruits and seeds necessary for the survival of different species, for our own food supply, and for industry would not …

Theses and Dissertations
In the community of Tunshi San Nicols of the Licto parish in the Province of Chimborazo, an evaluation was done on the effect of an energetic supplementary feeding of bees (Italian-mestizas) during the dry season (September 23 to February 20). These supplements consisted of carrot juice (T1), orange juice (T2) and sugar cane juice (T3). These supplements were also compared to a control group (T0). The experimental units consisted of 16 standard beehives distributed randomly with the 4 treatments and 4 repetitions of each treatment. The results showed that sugar cane juice (T3) obtained the best results in the consumption …
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 …
Drosophila Pseudoobscura Of The Great Basin, Monte E. Turner
Drosophila Pseudoobscura Of The Great Basin, Monte E. Turner
Theses and Dissertations
Four Utah populations of Drosophila pseudoobscura from the Wasatch Mountains in Utah were sampled and characterized for third chromosome gene arrangements. The original samples in this area were taken in 1940 and 1950. At that time the populations were essentially monomorphic for the Arrowhead arrangement, with small percentages of Pikes Peak and Chiricahua also found. The current samples show these populations to contain eight third chromosome arrangements; seven previously described (AR, PP, CH, ST, TL, OL, EP) and a newly discovered endemic arrangement (American Fork, AF), with breakpoints 63E and 70D. The frequency of AR had decreased to 25% in …
Bionomics Of Two Aspen Bark Beetles : Trypophloeus Populi And Procryphalus Mucronatus (Coleoptera:Scolytidae), Jerold L. Petty
Bionomics Of Two Aspen Bark Beetles : Trypophloeus Populi And Procryphalus Mucronatus (Coleoptera:Scolytidae), Jerold L. Petty
Theses and Dissertations
Beetles of Trypophloeus populi attacked green bark of unhealthy aspen (Populus tremuloides) and hastened the death of the tree. Beetles of Procryphalus mucronatus favored dead bark and were of little significance in the death of the aspen. These two beetle species were distinguished from each other by their primary galleries, eggs, larvae, larval mines, and mating behavior. In T. populi, there were three larval instars and one to one and one-half generations per year; only larvae overwintered, and the eggs of the first generation were present by mid-July. In P. mucronatus, there were two larval instars and one and one-half …

The Comparative Toxicity Of Developmental Inhibitors And Organophosphates On Mosquitoes, Richard L. Orr
The Comparative Toxicity Of Developmental Inhibitors And Organophosphates On Mosquitoes, Richard L. Orr
Theses and Dissertations
Four developmental inhibitors (Altosid, Altozar, ZR-619 and ZR-777) and two organophosphates (Parathion and Abate) were tested on Aedes aegypti under laboratory conditions. When applied to fourth-instar larvae, the organophosphates were more toxic than the developmental inhibitors. Concentrations required for standard kills (LC50 and LC95) were lower for Altosid and ZR-619 than for Altozar and ZR-777. Field applications of Altosid SR-10 controlled Culiseta inornata for two weeks at 4 ounces per acre. With the exception of Dolichopodidae, most non-target aquatic organisms showed little response to Altosid SR-10. Although the developmental inhibitors Altosid and ZR-619 require higher concentrations for mosquito control, they …

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 …
Ultrastructure Of Histochemically Localized Cholinesterases In Central And Peripheral Nervous Systems Of Two Insects: Periplaneta Americana L. And Acheta Domestica L, Clifford James Stratton
Ultrastructure Of Histochemically Localized Cholinesterases In Central And Peripheral Nervous Systems Of Two Insects: Periplaneta Americana L. And Acheta Domestica L, Clifford James Stratton
Theses and Dissertations
Cholinesterase (ChE) was histochemically localized by three methods in the sixth abdominal ganglion and the femur of crickets and cockroaches using light and electron microscopy. The light microscopy showed that ChE in insect femur could be readily demonstrated. The ultrastructural data showed enzyme activity: in ganglion - neural lamella, perineurium, axolemma, inside axons, along glia and at probable synapses; in peripheral nerves - in glial cells, sarcoplasmic reticulum, T-system, axolemma, sarcolemma and at neuromuscular junctions. All activity was inhibited with 10-4 eserine except in the neural lamella, suggesting cholinesterase at all of the above sites except the neural lamella where …
The Effect Of Insect Damage On Indian Ricegrass (Oryzopsis Hymenoides) In Western Utah, Luis S. Guerra
The Effect Of Insect Damage On Indian Ricegrass (Oryzopsis Hymenoides) In Western Utah, Luis S. Guerra
Theses and Dissertations
Indian ricegrass at the Desert Range Experiment Station forty-seven miles west of Milford, Utah, is damaged by the larvae of Coenchroa illibella, Diatrae sp. and Typoceris ceraticornis, the latter being the most destructive. The biology of the insects and the extent of damage inflicted are discussed. Uninfested plants produced more new stems than infested plants. Plants having a basal diameter of 4 to 6.9 cm and 7 to 9.9 cm were the most frequently infested and, consequently, the most severely damaged.
The Darkling Beetles Of The Nevada Test Site (Coleoptera - Tenebrionidae), Willis A. Packham
The Darkling Beetles Of The Nevada Test Site (Coleoptera - Tenebrionidae), Willis A. Packham
Theses and Dissertations
In the desert areas of southwestern United States the Coleoptera, family Tenebrionidae, constitute a conspicuous part of the ground-dwelling insects. Most species are black or dull chestnut-brown. They are primarily nocturnal and during the day can be found under rocks, debris, loose bark, or in rodent burrows. On cloudy days they may be seen lumbering along the desert floor. Most tenebrionids feed on plant materials of various sorts. In August, 1959, Brigham Young University initiated an ecological study at the Nevada Test Site near Mercury in Nye County, Nevada. As part of that study, emphasis was given to the ground-dwelling …
A Comparative Study Of The Axillary Sclerites In Coleoptera, Howard P. Shurtleff
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.
Observations On The Hibernation Of Culex Tarsalis Coquillett In Utah Valley, Utah, Dennis W. Trent
Observations On The Hibernation Of Culex Tarsalis Coquillett In Utah Valley, Utah, Dennis W. Trent
Theses and Dissertations
Culex tarsalis Coquillett is a common evening pest mosquito throughout the summer in most of temperate Western North America. Present evidence indicates this mosquito as the principal naturally infected vector of western equine encephalomyeltic (WEE) viruses. Certain interrelationships of WEE epidemiology and tarsalis bionomics are basically understood; however, in areas where winters are severe little is know of tarsalis hibernation, and the survival mechanism for WEE viruses in unknown. The purpose of this study, conducted from 1 September 1959 to 20 May 1960, was to gather ecological information on the hibernation of Culex tarsalis in Utah Valley, and secondly to …

Bionomics Of Culex Tarsalis Coquillett In Utah County, Stanley K. Taylor
Theses and Dissertations
This paper presents information concerning the bionomics of Culex tarsalis Coquillett in Utah County. Observations indicate that rock piles and talus slides are typical hibernation sites. The spring emergence from hibernation occurred between 28 March and 7 April 1959. Larvae breed in a great variety of habitats, including street-gutters, animal tracks, marshes and waste water from irrigation systems. The peak population density for both larvae and adults occurred during the first week in August. Charts, graphs, drawings and photographs are used in the presentation of data.
The External Morphology Of Pseudopanurgus Aethiops (Cresson), Glenn A. Hackwell
The External Morphology Of Pseudopanurgus Aethiops (Cresson), Glenn A. Hackwell
Theses and Dissertations
In comparing the head of Pseudopanurgus with Anthophora and Apis, the general outline appears rather similar, the most significant variation being found on the posterior surface. Extending ventrally from the postoccipital suture to the dorsal wall of the proboscidial fossa is a suture known as the fused hypostomal suture. The hypostomal area is rather small and makes up only a small portion of the dorsal and lateral walls of the proboscidial fossa, the remainder being formed by the postgena. If this is correct, the hypostomal carinae (a term with which the author does not agree) are actually located on the …

A Morphological Study Of Some North American Sitona (Coleoptera: Curculionidae), George J. Kidd
Theses and Dissertations
This study was undertaken to identify, if possible, some morphological characteristics of the U. S. Sitona species that would help simplify the classification of this difficult group. Because of extreme difficulty in obtaining positively identified specimens of all species reported, the scope was limited to eight identified species and one unidentified series. External structures studied include mouth parts, appendages, eyes, wings, and genitalia. The spermathecae were the only internal structures analyzed. Mandibular profiles were compared throughout the species represented and variations were noted. Labia and maxillae were observed but no distinctive differences were noticed. Antennae were found to be quite …
A Taxonomic Study Of The Families Of Utah Coleoptera Excluding Rhynchophora, T. Blaine Moore
A Taxonomic Study Of The Families Of Utah Coleoptera Excluding Rhynchophora, T. Blaine Moore
Theses and Dissertations
During the years 1950-51 work was begun on a study of the Coleoptera by the author. In 1955, due to the lack of a workable set of keys to the Coleoptera of Utah, a study was undertaken to find a way to more easily classify the beetles of the state to their respective families. The collection of Brigham Young University was used as the basis for determining the families of beetles actually found in Utah. Then a thorough search of the literature was made to find positive records of Utah families not represented in that collection. It was found that …
