Influence Of Food Plants On Fecundity, Larval Development And Abundance Of The Tuber Flea Beetle In Nebraska, Roscoe E. Hill

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Laboratory and field tests were conducted to determine the effects of different food plants on fecundity, adult longevity and larval development of the tuber flea beetle, Epitrix tuberis Gentner. All food plants tested were those upon which the overwintered beetles commonly feed in the spring following emergence from hibernation.

Effects Of Ddt And Other Insecticides On Several Species Of Potato Insects, Roscoe E. Hill

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Field and laboratory tests conducted in Nebraska showed DDT to be more effective than any other material yet tested against potato insect pests. Records were obtained on tuber flea beetles, Epitrix tuberis, potato psyllids, Paratrioza cockerelli, potato leafhoppers, Empoasca fabae, green peach aphids, Myzus persicae, Lygus elisus, Chlamydatus associatus, Aceratagallia uhleri and Macrosteles divisus. DDT remained effective against potato psyllids and potato leafhoppers under field conditions for a relatively long period of time. Populations of certain beneficial insects, such as Nabis spp., Orius spp. and lady beetles were found to be significantly reduced …

The Mosquitoes Of Nebraska, H. Douglas Tate, Doris B. Gates

Nebraska Agricultural Experiment Station: Historical Research Bulletins

A survey of mosquitoes in Nebraska was conducted by the Nebraska Agricultural Experiment Station during 1942 and 1943. The object of the study was to determine the species, relative abundance, seasonal occurrence, and principal breeding places of mosquitoes in representative areas of the state. This report presents the results of the survey, and, in addition, some records and observations made in Nebraska by other workers during and previous to initiation of the project.

External Parasites Of Poultry And Methods For Their Control, O. S. Bare

Nebraska Agricultural Experiment Station: Historical Circulars

External parasites cause severe losses to Nebraska poultry producers each year, and in many cases may be the deciding factor between success and failure. Under present circumstances, when maximum production is essential, prompt and effective measures must be taken to hold these saboteurs in check.

Controlling Stored-Grain Pests On Nebraska Farms, H. D. Tate, D. B. Whelan

Nebraska Agricultural Experiment Station: Historical Circulars

Warfare against destructive insects is not ended when grain has been placed in the bin. Here it is subject to attack by stored-grain pests which reduce its weight, feeding quality, and value for seed. These losses become especially serious when large stocks of grain are held for extended periods on farms and in warehouses. This circular describes methods available for handling and storage that will prevent or suppress infestations before they reach serious proportions.

Control Of The Chinch Bug In Nebraska, M. H. Swenk, H. D. Tate

Nebraska Agricultural Experiment Station: Historical Circulars

The chinch bug, Blissus leucopterus (Say), is one of the most injurious insect pests of cereal crops in the United States. Although some damage by it has occurred over a wide area in the United States, the greatest injury has been in the Corn Belt. The years in which the chinch bug appears in destructive abundance come irregularly in cycles of varying duration, and the length of these cycles is largely controlled by the direct or indirect effects of weather upon the bugs. Continued dry weather favors them, while very wet weather brings about their destruction. During the last seven …

Control Of Stored Grain Pests In Nebraska, M. H. Swenk, D. B. Whelan

Nebraska Agricultural Experiment Station: Historical Circulars

At the close of 1939 about twice the amount of wheat was in storage in Nebraska as compared to the close of 1938. Frequently a new crop of grain goes into storage before the preceding older grain leaves the farm, and, due to inadequate storage space, the crops are not kept separated, thus promoting an early infestation of the new grain from the older grain that has become infested. Under such conditions the damage by stored grain pests becomes a matter of unusual importance.

Spraying Tree Fruits, C. C. Wiggans, E. H. Hoppert

Nebraska Agricultural Experiment Station: Historical Circulars

The production of sound, clean fruit is unquestionably one of the major problems facing the modern fruit grower. Culture may be neglected and pruning delayed for a time but the omission of sprays for even a single season demonstrates their absolute necessity. This applies equally to the commercial grower and to the farmer or gardener who has only a few trees.

Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott

Nebraska Agricultural Experiment Station: Historical Circulars

In Nebraska, a hustling frontier state in 1887, the legislature hesitated not at all in taking advantage of the provisions of the Hatch Act, and now that fifty years have elapsed since the Station was founded, seventy-five years since the Land Grant College Act was passed and the U. S. Department of Agriculture established, and almost twenty-five years since the Agricultural Extension Service was added, it seems worth while to present a general summary of achievement within the state. The main object will be to show some of the important things that have been learned through the investigations of the …

The Gizzard Worm And Its Transmission To Chickens In Hawaii, Joseph E. Alicata

Harold W. Manter Laboratory of Parasitology: Library Materials

Gizzard-worms of poultry, Cheiloapirura hamulosa, are nematodes occurring in the gizzards of chickens and turkeys.

Summary and Conclusions

Previous to this report the carriers for the gizzard-worm in Hawaii were unknown. Recent investigations by the writer have shown that the flour beetle, Tenebroides nana, and the sand hopper, Orchestia platensis, collected from poultry farms in the Territory of Hawaii have been found naturally infested with the infective larvae of the poultry gizzard-worm, Cheilospirura hamulosa. Out of 8 laboratory-raised chickens to which there were fed about 2,300 grasshoppers that had been collected in an endemic gizzard-worm area, …

A Key To The Nebraska Cutworms And Armyworms That Attack Corn, Don B. Whelan

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The following key to the Nebraska cutworms and armyworms injurious to corn is based upon structural characters supplemented in some instances by color. Not all of the species in this key have been found in Nebraska; some are included because they are to be found in near-by states to such an extent that they probably are present in this state.

Infection Experiments With Spindle Tuber And Unmottled Curly Dwarf Of The Potato, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is probable that more than one insect species are capable of spreading some of the potato virus diseases. This conclusion was also indicated by repeated observations in the dry-land section of western Nebraska. While aphids are abundant and are probably the chief vectors of potato virus diseases in the more humid sections of the country, they are usually scarce in the western upland plains area and are not present in large enough numbers to account for the rapid spread of spindle tuber and unmottled curly dwarf which sometimes occurs. It was therefore considered advisable to determine the common potato …

Leaflet No 256 - Climbing Cut-Worm Or Tomato Moth (Chlorodea Obsoleta), L. J. Newman

Bulletins 1 - 2999

During the past spring caterpillars of various kinds have been unusually prevalent. In some instances they have been so numerous as to constitute a plague.

The caterpillar most in evidence was the larva of the Climbing Cut-worm or Tomato Moth.

The Insects And Mites Injurious To Poultry In Nebraska And Their Control, M. H. Swenk, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

There are a number of different kinds of insect and mites (arthropods) that are more or less injurious to poultry in Nebraska. This circular is designed to give practical information concerning these pests and their control.

Further Experiments With Poisoned Baits For Grasshoppers, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In the summer of 1922 a series of experiments was carried on at the Scotts Bluff Experiment Substation for the purpose of finding, if possible, a formula for preparing an inexpensive and efficient poisoned bait for grasshoppers that could be recommended to the farmers of the North Platte valley, and also of learning more concerning the relative values of certain attractants and poisons commonly used in such baits, as well as the best time to scatter them to obtain the most satisfactory results. While the results were fairly conclusive from a qualitative standpoint, the time was not available in the …

The Pine Tipmoth In The Nebraska National Forest, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Research Bulletins

On May 8, 1911, Mr. Smith Riley, the District Forester, with headquarters at Denver, in a letter to Acting Supervisor Pierce at Halsey, requested that the Nebraska Agricultural Experiment Station take up energetically the investigation of the pine tipmoth in the Nebraska National Forest. This request being presented to the Department by Mr. Pierce later in the month resulted in the presentation of the problem to the Experiment Station Council as a proposed Station project. The project was approved on May 31, 1911, and the expenses of the investigations of 1911 and 1912 that are reported upon in this bulletin …

The Chinch Bug And Its Control, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Circulars

During the last half century there have been five separated and well-marked chinch bug outbreaks, or periods of serious damage, in Nebraska, and we are now approaching the climax of a sixth such period. As to just how serious this present outbreak will be in 1925 no one can now say, because no one can exactly forecast the weather conditions of the summer, but the present situation is sufficiently menacing to make advisable the issuing of this circular, which aims to give the essential information concerning the chinch bug as a Nebraska pest, and the locally applicable means of control.

The Plains False Wireworm And Its Control, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Circulars

The last three crops of winter wheat, and especially the crop of 1922-23, have been seriously injured in southwestern Nebraska and especially on the dry land farms of Cheyenne, Kimball, Banner, Morrill, Garden, Deuel , Keith, Perkins, and Hitchcock Counties, by an abundance of hard-bodied, cylindrical, shining waxy yellow, soil-infesting larvae. These greatly resemble wireworms and are often mistaken for them, but they differ conspicuously in being more active and having well-developed, club-shaped antennae, long and stout front legs, and a less flattened body with a distinctly upturned tip. These larvae destroy the planted seed in the fall and eat …

Bulletin 106 - The Red-Legged Velvet Earth Mite, L. J. Newman

Bulletins 1 - 2999

This pest is sometimes called in error the "Red Spider" or the 'Earth Flea."

It is neither a spider nor a flea, being a species of mite.

It belongs to the family of mites known as the Eupodidae and to the Genus Notophallus. Many of the members of this family are predaceous, that is, they live upon other insects or animals, but the species we are dealing with appears to be wholly a plant feeder. A popular idea is that the mite lives and breeds in the earth. The rapidity with which newly planted vegetables become infested gives good excuse …

Insect Pests Of Stored Grains And Their Control, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Circulars

In Nebraska there are about 20 species of insects that injure stored grain more or less. Some are beetles and their larvae, others are the caterpillars of small moths. To the farmer all are "weevil," although that name is really properly applied only to two beetle species-the granary weevil and the rice weevil. The following paragraphs and illustrations will describe the several more important stored grain pests to be found in this State, so that the farmer may recognize the particular pest or pests that are doing the injury to his grain, and may then apply the proper remedy.

Spraying Experiments In Nebraska, J. Ralph Cooper

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The more important questions which were considered during the three years covered by the present report were as follows: 1. How many summer sprays are required and when should they be applied? 2. What is the difference in efficiency between various brands of arsenate of lead? 3. What are the relative values of lime sulphur and Bordeaux as fungicides for spraying apples? 4. Is it possible to lessen or prevent Bordeaux injury and at the same time control fungous diseases? 5. Is it possible to interchange Bordeaux and lime sulphur in a spray schedule in such a manner as to …

New Elementary Agriculture For Rural And Graded Schools, Charles E. Bessey, Lawrence Bruner, G. D. Swezey

Department of Entomology: Faculty Publications

Nebraska is an agricultural state. The products of her soil are the basis of her industries and her prosperity. The children of our great state of Nebraska should be familiar with our crops, our grains and grasses, our flowers and fruits, our trees and shrubs and weeds, our domestic animals and birds and insects. Our children should have a practical knowledge of the management of a farm, of the composition of the soil, and of the adaptability of the farm and its soil for the cultivation of certain plants and the counter effect of such plant growth upon the soil. …

A Preliminary Introduction To The Study Of Entomology, Lawrence Bruner

Department of Entomology: Faculty Publications

This book has been prepared for the purpose of partially supplying a demand that seems to exist here in the West for an elementary work on entomology such as can be used in the public schools and on the farm. It is not an original production, but comprises notes from many sources as they have been gathered by the writer and presented from time to time in talks to his classes in the University of Nebraska and before audiences at farmers' institutes throughout the state. The chapters on remedies and on apple and small grain insects have been compiled and …

Insect Enemies Of The Small Grains, Lawrence Bruner

Department of Entomology: Faculty Publications

Although "corn is king" in Nebraska, our crops of small grains are not insignificant. The insect enemies of wheat, oats, barley, and rye therefore demand our attention nearly or quite as much as do those which attack corn. Accordingly, during the past year much time has been given to the study of this class of insect pests. While many of the species are identical for the different crops, the nature of the plants themselves being unlike, it necessarily follows that the mode of attack among these enemies must vary somewhat in each case. This being true, some pains has been …
