Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
This is the third and most comprehensive study of pesticide use on crops in Nebraska. The first was completed in 1978 and the second one in 1982. The first study indicated that approximately 25 million pounds (11.34 million kg) of active ingredients were used on the major crops in Nebraska. This increased to approximately 30.2 million pounds (13.7 million kg) in 1982. The USDA requires accurate information to meet their responsibilities. Thus, this survey was undertaken to determine: 1) the use of pesticides on crops, pasture and rangeland and 2) to identify pest management practices.
Influence Of Food Plants On Fecundity, Larval Development And Abundance Of The Tuber Flea Beetle In Nebraska, Roscoe E. Hill
Influence Of Food Plants On Fecundity, Larval Development And Abundance Of The Tuber Flea Beetle In Nebraska, Roscoe E. Hill
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
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.

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 …
