A Synopsis Of The Syrphidae Of Nebraska With Descriptions Of New Species From Nebraska And Colorado, Everett E. Wehr

University Studies (University of Nebraska) (1888–1984)

In June, 1907, Mr. Paul R. Jones published in the Journal of the New York Entomological Society "A Preliminary List of Nebraska Syrphidae with Descriptions of New Species.'" At that time there was available only a comparatively small collection of Syrphid flies, but apparently it contained a fairly good representation of the species found in the state. Subsequent collectors have contributed a considerable amount of new material from the state in which there are twelve additional species, two of which are· new. With these additions, the Nebraska list is increased to ninety species.

At the present time the classification of …

Garden Pests And Diseases, A. L. Ford

SDSU Extension Circulars

There are hundreds of species of insects and hundreds of different plant diseases that attack our garden crops here in South Dakota. They are always in danger from these. This being the case there is but one thing for each garden club member to do and that is to learn the best way to get rid of the pest before the pest comes. If you’ll do that you will always be ready and the boy or girl who is ready in a case like this is going to win out.

Insect Pests And Plant Diseases Of The Strawberry Bed, A. L. Ford

SDSU Extension Circulars

Insect pests and plant disease cause a continual loss in many strawberry beds. As a rule this loss is disregarded by the average grower who believes that there is nothing practical that can be done. We maintain that for an individual to grow strawberries efficiently, he must give this loss caused by insect pests and plant disease due consideration.

Variations In Cytology And Gross Morphology Of Taraxacum Ii. Senescence, Rejuvenescence, And Leaf Variation In Taraxacum, Paul B. Sears

Papers in Ecology

The variability of Taraxacum has frequently been recorded in botanical literature without receiving much elucidation. It is less often an object of investigation than of conjecture and discussion. A few botanists have studied the effect of environmental factors upon Taraxacum, but their results have not cleared away taxonomic difficulties. Systematic botanists have either looked upon the variations in this genus as fluctuations or slight mutations, and then proceeded to lump or split as judgment might dictate. That life history exerts a profound influence upon form seems generally to have escaped attention.

Anthocyan Pigments, Paul B. Sears

Papers in Ecology

Noack has found rhamnose-free flavonol diglucosides to be much more abundant in green leaves than has generally been supposed. In such leaves as he studied he was able to establish the existence of flavonol-anthocyan in couples of similar glucosidal nature, but secured no evidence of aromatic nucleus composition in such cases. He suggests that these couples function as a reduction mechanism during photosynthesis.

The Preparation Of Laboratory Specimens As An Aid To The Diagnosis Of Animal Diseases, L. Van Es, L. V. Skidmore

Nebraska Agricultural Experiment Station: Historical Circulars

Many problems in connection with animal diseases require for their solution the application of methods which can only be undertaken at properly equipped laboratories. This ordinarily involves the collection, packing, and shipping of samples of specimens. The manner in which this is done is a most important factor and to a very large extent is responsible either for the success or for the failure of the undertaking. The discussion of the subject to which the following pages are devoted is taken in hand in the hope that it may provide guidance to the veterinarians and others who may have occasion …

The Common Intestinal Roundworm Of Swine (Ascaris Lumbricoides), H. M. Martin

Nebraska Agricultural Experiment Station: Historical Circulars

The large intestinal roundworm of pigs is a very common parasite and is probably present in every hog raising district of Nebraska. Up until the last few years the true nature of this parasite was unknown. Little did we realize the actual harm done by this worm; but through the scientific investigations of Stewart, Ransom, and others we now know that this parasite causes heavier losses to the breeder and feeder of swine than any other now common in Nebraska.

Late Spring Management Of The New Strawberry Bed, A. L. Ford

SDSU Extension Circulars

One of the most essential things in successful strawberry growing is a proper amount of the right kind of cultivation. No boy or girl club member can ever expect to break club yield records without cultivation (hoeing) his patch. Why is it that cultivation is so necessary in strawberry growing? There are four principal reasons, and they are taken up separately below. (See more in text).

Planting The Strawberry Bed, A. L. Ford

SDSU Extension Circulars

You have probably ordered your plants by this time and would, undoubtedly, want to know how much ground to prepare for them. In speaking of strawberry beds we will use the square rods as the unit area. The number of plants necessary for a square rod of ground depends entirely upon the planting system you choose to use. There are three common systems of planting and training strawberry beds, namely, (1) the hill system, (2) the hedge row system, (3) and the matted row system. These are taken up separately below. (See more in text).

Variations In Cytolgoy And Gross Morphology Of Taraxacum, I. Cytology Of Taraxacum Laevigatum, Paul B. Sears

Papers in Ecology

These investigations are the outgrowth of a study, begun in 1914 at the instance of the late Professor C. E. Bessey, of parthenogenesis in Taraxacum vulgare (Lam.) Schrk. and T. laevigatum ( Willd.) DC. These two species are the common ones in central United States, being respectively designated as Leontodon taraxacum L. and L. erythrospermum (Andrz.) by Britton and Brown (3). In 1917 the existence of ameiotic parthenogenesis in both species was confirmed (23) and certain pollen abnormalities briefly described. These abnormalities have invited more critical analysis as a means of throwing light upon certain phases of variation …

Grasshoppers, Cutworms And Army Worms And Their Control By Poisoned Bran Mash, A. L. Ford

SDSU Extension Circulars

Were it possible to accurately estimate in dollars and cents the average annual loss caused by grasshoppers, cutworms, and army worms to the growing crops of South Dakota, the figure arrived at would be a staggering one. These three pests cause a greater average annual damage than any other three insect pests in the state. Natural conditions here are such that we may expect outbreaks from any of these three in any part of the state for many years to come. Being situated in this manner, it behooves every farmer in South Dakota to be prepared to fight these pests …

The material contained in this bulletin is a culmination of several years' study and investigation of the different types of hog houses used in Nebraska. It is realized that the plans given will not suit all conditions that may arise, but an effort has been made to bring out the essential factors so that the plans may serve as a guide in planning a house suited to particular conditions.

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.

Farm Layout And Field Arrangement, H. D. Mccullough

SDSU Extension Circulars

Farm layout involves the location of the fields with respect to the farmstead and public highways, the size, shape and number of fields, and the location of hog-lots, feed yards, etc. In arranging or re-arranging a farm layout the most important considerations are convenience and economy of operation. An ideal farm layout is so arranged that there shall be a minimum of time consumed, no retracing of steps and no lost motion in doing the routine work of the farm.
