Parasites, Predators, And Other Arthropods Associated With Choristoneura Houstonana (Lepidoptera: Tortricidae) On Juniperus Species In Kansas, E. A. Heinrichs, Hugh E. Thompson

Department of Entomology: Faculty Publications

One parasitic dipterous species and 27 parasitic hymenopterous species were collected. Parasites were primarily collected by mass-rearing host larvae on cut host plant foliage in the laboratory or by rearing larvae on artificial diet. The tachinid Nemorilla pyste (Walk.) and five hymenopterous species, Glypta n. sp. (Ichneumonidae), Campoplex sp. (Ichneumonidae), Agathis acrobasidis (Cushman) (Braconidae), Elasmus atratus How. (Eulophidae), and Catolaccus aeneoviridis Girault (Pteromalidae), were definite parasites, and biological notes are given. Collection data are also given for the other 22 species.

One reduviid predator, Zelus socius Uhler, and six spiders were observed feeding on C. houstonana.

Migration Of The Army Cutworm, Chorizagrotis Auxiliaris (Lepidoptera: Noctuidae). I. Evidence For A Migration, Kenneth P. Pruess

Department of Entomology: Faculty Publications

Indirect evidence is presented to support the conclusion that the army cutworm, Chorizagrotis auxiliaris (Grote), migrates from the Great Plains to the Rocky Mountains during the spring and the same individuals return to the Plains in the fall. Spring activity occurs progressively later from east to west, the delay being greater than that caused by emergence but commensurate with flight potential of the moth. Flight is predominately from east to west and a constant turnover of moths occurs at all locations on the Plains. Seasonal occurrence in the mountains coincides with the period of inactivity on the Plains, during which …

European Corn Borer, Ostrinia Nubilalis (Hbn.) Populations In Field Corn, Zea Mays (L.) In The North Central United States, R. E. Hill, A. N. Sparks, C. C. Burkhardt, H. C. Chiang, M. L. Fairchild, W. D. Guthrie

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A long-range study of the annual changes in corn borer populations in the North Central States was started in Minnesota, Iowa, Kansas and Nebraska in 1955 and in Missouri and Ohio in 1956. This investigation was a phase of a broader Regional Project, NC-20, entitled "Factors Influencing Corn Borer Populations" and was undertaken to measure by standardized procedures the seasonal changes in abundance of the European corn borer, Ostrinia nubilalis (Hbn.), under cropping procedures in different locations within, the North Central States. Much valuable information has been accumulated on the abundance and effects of various physical and biotic factors on …

Distribution Of Eggs And Leaf Mines Of Choristoneura Houstonana (Lepidoptera: Tortricidae) Attacking Eastern Red Cedar, Juniperus Virginiana, Elvis A. Heinrichs

Department of Entomology: Faculty Publications

Cedar at Larned, Kansas, appeared to be more severely damaged in the upper and southern portions of the trees. There was a significant difference, in numbers of eggs and leaf mines, between the upper and lower halves and between compass directions; the upper and southern portions of the trees being most highly infested.

Choristoneura houstonana (Grote) is a pest of eastern red cedar, Juniperus virginiana, grown as a home landscape ornamental in shelter belts and windbreaks in western Kansas. It has been present for many years but the first reliable record in Kansas was in 1964, when it was sent …

Factors Influencing Population Growth Of Tribolium Brevicornis In The Laboratory, Amin Gulla

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To determine the effect of the factors of the environment (temperature, relative humidity, and food) on the population growth of Tribolium brevicornis, different levels of temperatures from 17.5°C - 37.5°C were used. Effect of these IeveIs of temperatures was tested upon both pre-embryonic and post-embryonic development. No hatching occurred at 17.5°C, but the threshold temperature (the minimum temperature for the development) was just before 17.5°C. The optimum temperature for the embryonic development was found to be between 32.5°C - 35°C.

With the use of the saturated salt solution according to Buxton (1931) and Buxton and Melanby (1934), certain humidity …

Seed Size As Related To The Selection Of Alfalfas Resistant To The Seed Chalcid Bruchophagus Roddi, L. S. Rogers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Several studies have been made by others to try to find a better method of selecting alfalfa that is resistant to seed injury by the alfalfa seed chalcid. This study investigated the possibility of using seed size as a basis of selection for resistance.

Data in this thesis show that the stage of seed development when chalcid oviposited in the seeds did affect the size of seeds. Larger seeds were infested when alfalfa seed chalcid were introduced early in the development of seeds (five days after pollination), and the total number of seeds produced was slightly greater when chalcids were …

Protecting Honey Bees From Pesticides, U.S. Department Of Agriculture

An

Honey bees frequently are in danger of being killed when crops are treated with pesticides. Honey bees produce honey and beeswax valued at $55 million annually; but even more significant, the annual value of crops that require bee pollination exceeds $1 billion. For this reason, farmers and beekeepers should cooperate in protecting the bees from pesticides. Observance of precautions recommended in this publication can significantly reduce bee losses from pesticide poisoning.

The Summer Standing Crop, Growth And Distribution Of Chironomus Plumosus, In Lake Itasca, Minnesota, James C. Underhill, Gerald A. Cole

Journal of the Minnesota Academy of Science

During the period 15 June to 3 September 1965, 626 Ekman dredge hauls were made in Lake Itasca, Minnesota. The numbers and weights of Chironomus plumosus L. at 6 m, 7 m, 8 m, Siefert's Hole (9.5 - l 0.4 m), and Peace Pipe Vista (11.5 - 13.7 m) depression were determined. In addition, the numbers and weights of several other benthic dipteran larvae, Cryptochironomus, Palpomyia, and Procladius, normal associates of C. plumosus, were determined. A loss of 98,407 larvae/ha/day occurred in the 6-9 m stratum during the 12 weeks. There was a decrease in numbers of larvae of 79.3% …

Seventy-nine species and one subspecies are recognized. Sixteen names are relegated to synonymy, one to homonymy and eight are removed from the subgenus Callandrena. The thirty-nine species new to science are: aerifera, aeripes, afimbriata, ardis, auripes, balsamorhizae, beameri, bilimeki, bullata, calvata, dreisbachorum, fulminea, fulminoides, …

The House Fly, 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.

A New Species Of Rhinoceros, Aphelops Kimballensis, From The Latest Pliocene Of Nebraska, Lloyd G. Tanner

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

An uncrushed skull and associated skeletal elements of a very large rhinoceros are the basis for the description of a new species of Aphelops from Frontier County, Nebraska. The major differences are: the skull is much larger in most dimensions than other Aphelops; it has an extremely elevated occipital region in comparison to Aphelops mutilus; the narial notch is retracted to a point perpendicular to the center of molar one; and the teeth are more hypsodont than any other species of this genus. The sediments which yielded the skull and skeletal parts are considered to be Kimballian in …

The Brule-Gering (Oligocene-Miocene) Contact In The Wildcat Ridge Area Of Western Nebraska, C. Bertrand Schultz, Charles H. Falkenbach, Carl F. Vondra

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

The contact between the Brule Formation (Oligocene) and the Gering Formation (Miocene) can be readily distinguished in the Wildcat Ridge area, as elsewhere in western Nebraska. At the critical fossiliferous exposures at Castle Rock in Scotts Bluff County, the contact on the south face between the two formations is defined as 129 feet above the base of the "Upper Ash" bed, which corresponds to the upper portion of Darton's (1899, PI. C, Fig. D, following p. 754) "sandy phase" in the upper part of the Brule. Certain key beds in the Gering Formation can be traced laterally from a channel …

A Check-List And Keys To The Primitive Sub-Families Of Cerambycidae Of Illinois, Michael Jon Corn

Masters Theses

The long-horned beetles, family Cerambycidae, form a large, colorful, often-collected and well-known group. However, the drab, more primitive subfamilies, Parandrinae, Prioninae, Aseminae, and Spondylinae, are much less well-known although they often appear in collections.

In this paper, the author has attempted to list those species of primitive cerambycids which occur or are likely to occur within the State of Illinois. Keys, illustrations, descriptions, and distribution maps have been developed to aid in identification. The list and keys should be applicable to any midwestern state with the addition or deletion of a few species.
