The Exotic Agrilus Cyanescens (Ratzeburg) (Coleoptera: Buprestidae) Is Discovered In Oregon, Richard L. Westcott, Wyatt Williams, Amy Grotta Jan 2019

The Exotic Agrilus Cyanescens (Ratzeburg) (Coleoptera: Buprestidae) Is Discovered In Oregon, Richard L. Westcott, Wyatt Williams, Amy Grotta

Insecta Mundi

In two separate occurrences, graduates of the Oregon Forest Pest Detector program discovered the exotic Agrilus cyanescens (Ratzeburg) (Coleoptera: Buprestidae) in Portland, Oregon, damaging a backyard shrub, Lonicera involucrata (Rich.) Banks ex Spreng. (Caprifoliaceae). Although first detected in the USA 99 years ago, the known occurrence nearest to Oregon is in Utah.

Insecta Mundi

Xylotrechus rameyi, new species, (Coleoptera: Cerambycidae) is described from southern Utah. Comments on its biology including habitat, host plants and larval history are provided along with photographs of the holotype, allotype, the related species X. insignis LeConte, and the larval galleries and pupal chamber.


Larval Biology Of Some Utah Chrysididae, Bakary Vassery Ouayogode May 1979

Larval Biology Of Some Utah Chrysididae, Bakary Vassery Ouayogode

All Graduate Theses and Dissertations

Biologies of eight chrysidid species were described. These wasps parasitized bees and wasps collected in trap nests set at several sites in two canyons near Logan, Utah. The completed nests were taken to the laboratory and the parasitized ones were kept for study of the development a l biology and behavior of both host and parasites.

The larval stages of Chrysura smaragdicolor, Chrysura sonorensis, Chrysis parkeri, Chrysis derivata, Chrysis coerulans, Cerotachrysis enhuycki, Trichrysis doriae and Hedychridium solierellae were studied. Omalus iridescens and Omalus purpuratus larvae were observed only in the fifth instar. The major differences between species or genera were ...

The Bees Of Curlew Valley (Utah And Idaho), George E. Bohart, G. F. Knowlton Jan 1973

The Bees Of Curlew Valley (Utah And Idaho), George E. Bohart, G. F. Knowlton

All PIRU Publications

In America north of Mexico there are an estimated 4,000 species of bees distributed in approximately 110 genera. In Curlew Valley, 132 species in 33 genera have been identified, and approximately 25 additional unidentified species have been collected. It is likely that at least 225 species in 40 genera should be found eventually. The bee fauna of Curlew Valley can be roughly divided into the following 4 categories on a seasonal basis.


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

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).

The alfalfa weevil has become one of the more important insect problems currently affecting American agriculture. Recently, this problem has attracted national attention because of the development of resistance to insecticides by the alfalfa weevil, the outlawing of certain pesticides for use on forage crops and the rapid spread of the alfalfa weevil to new areas.

With this increased attention, many ...


Cuterebra (Diptera: Cuterebridae) Of Utah And The Neighboring States, Charles L. Graham May 1962

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

All Graduate Theses and Dissertations

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 ...

Insect Pollinators Of Carrots In Utah, George E. Bohart, William P. Nye Apr 1960

Insect Pollinators Of Carrots In Utah, George E. Bohart, William P. Nye

All PIRU Publications

IN THE course of observation at Logan, Utah, on the occurrence and pollinating activities of insects on carrots grown for seed, 334 species representing 71 families, were collected. Most numerous in species were the hymenopterous families and superfamilies Sphecidae, Apoidea, Psammocharidae, Vespidae, and Ichneumonidae, and the dipterous families Syrphidae, Tachinidae, Bombyliidae, Stratiomyidae, and Sarcophagidae. Most numerous in individuals were the dipterous families Syrphidae, Ceratopogonidae, Chloropidae, and Piophilidae and the coleopterous family Coccinellidae. Families and superfamilies represented by the most efficient pollinators were Apoidea, Sphecidae, Syrphidae, and Stratiomyidae. Abundance times efficiency was used as a pollination index for each species. On ...

A Taxonomic Study Of The Scolytidae (Coleoptera) Of The Logan Canyon Area Of Utah, Stephen L. Wood May 1947

A Taxonomic Study Of The Scolytidae (Coleoptera) Of The Logan Canyon Area Of Utah, Stephen L. Wood

All Graduate Theses and Dissertations

In spite of the great economic importance of north American Scolytidae, many taxonomic descriptions remain inadequate for the identification of species, and existing keys have been made obsolete by the recent description of new species. To bring these keys up to date and make them useful to students and practical foresters, detailed studies of the morphological structure of the various species are necessary. The purpose of the present investigation has been to clarify and revise existing keys and to describe briefly the species of Scolytidae occurring in the Logan Canyon area of Utah. The following keys and descriptions will be ...
