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.

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 Plea For The Protection Of Our Birds, Lawrence Bruner

Department of Entomology: Faculty Publications

The fact that insect depredations are increasing in extent each succeeding year makes it plain to us that something must be done to prevent it, and that quickly. We have found to our sorrow that, although we are continually making increased efforts to destroy these pests, our efforts avail but little and the destruction of our crops goes on. What, then, is to be done? How can we be released from this ever-increasing struggle for existence? The answer is plain. Heed the advice of the Naturalist who has made a study of the life-histories of the various other living creatures …

Spermatogenesis Of The Butterfly, Papilio Rutulus, John P. Munson

All Faculty Scholarship for the College of the Sciences

For a number of years I have been studying the spermatogenesis of Papilio rutulus (pl. 12, fig. 1) not ,with any one single problem especially in view, but with the aim of ascertaining the entire life history of its sperm cell, its various phases of development, its mode of growth and differentiation, the history of its several parts, and its relation to the organism.
