Evaluation Of Ulv And Thermal Fog Mosquito Control Applications In Temperate And Desert Environments, Seth C. Britch, Kenneth J. Linthicum, Wayne W. Wynn, Todd W. Walker, Muhammad Farooq, Vincent L. Smith, Cathy A. Robinson, Branka B. Lothrop, Melissa Snelling, Arturo Gutierrez, Hugh D. Lothrop, Jerry D. Kerce, James J. Becnel, Ulrich R. Bernier, Julia W. Pridgeon

Publications from USDA-ARS / UNL Faculty

Ultra-low-volume (ULV) and thermal fog aerosol dispersals of pesticides have been used against mosquitoes and other insects for half a century. Although each spray technology has advantages and disadvantages, only 7 studies have been identified that directly compare their performance in the field. US military personnel currently operating in hot-arid environments are impacted by perpetual nuisance and disease vector insect problems, despite adulticide operations using modern pesticide-delivery equipment such as ULV. None of the identified comparative studies has looked at the relative feasibility and efficacy of ULV and thermal fog equipment against mosquitoes in hot-arid environments. In this study we ...

Kansas Agricultural Experiment Station Research Reports

A 360-d study was performed to evaluate the effects of environmental conditions on storage stability of exogenous phytases. Coated and uncoated products from 3 phytase sources (Ronozyme P, OptiPhos, and Phyzyme) were stored as pure forms, in a vitamin premix, or in a vitamin and trace mineral (VTM) premix. Pure products were stored at 0, 41, 73, and 99ºF (75% humidity). Premixes were stored at 73 and 99ºF. Sampling was performed on d 0, 30, 60, 90, 120, 180, 270, and 360. Sampling of the pure products stored at 0 and 41ºF was discontinued after d 120 due to mold ...

Kansas Agricultural Experiment Station Research Reports

A total of 283 pigs (PIC TR4 x 1050, initially 77.2 ± 1.4 lb BW) were used to compare phase feeding with blending finishing diets by using the FeedPro system (Feedlogic Corporation, Willmar, MN). There were 3 experimental treatments: (1) a standard 4-phase complete feed program, (2) blending high- and low-lysine complete diets over the entire experiment, and (3) blending ground corn and a separate complete supplement within each phase. FeedPro is an integrated feed dispensing system that can deliver and blend 2 separate diets while dispensing. The 4 phases were 77 to 120, 120 to 175, 175 to ...

The Effects Of Feeder Space And Adjustment On Growth Performance Of Finishing Pigs, A J. Myers, J R. Bergstrom, Robert D. Goodband, Michael D. Tokach, Joel M. Derouchey, Jim L. Nelssen, Steven S. Dritz

Kansas Agricultural Experiment Station Research Reports

A total of 288 pigs (PIC TR4 x 1050, initially 82 lb) were used in a 91-d study to evaluate the effects of feeder trough space (1.75 vs. 3.5 in/pig) and minimum feeder-gap opening of 0.5 in. (narrow), vs. 1.0 in. (wide) on finisher pig performance. Our hypothesis was that at minimal feeder trough space (1.75 in./pig), feeders should be set at a wide gap opening to avoid limiting feed intake and ADG. The feeders were adjusted to the minimum gap setting, but the agitation plate could be moved upward to a maximum ...
