153.  Derived from:  Legner, E. F., R. D. Sjogren, G. S. Olton & L. Moore.  1976.  Control of biting and annoying gnats with fertilizer.  Calif. Agric. 30(2):  14-17.




          Naturally breeding field populations of Hippelates eye gnats and Leptoconops biting gnats were reduced with granular and spray applications of urea to the soil.  Control ranged from 10-96 percent depending on the dosage and application method (disked or surface-applied).  Possible modes of action are mechanical abrasion of gnat larvae, and the favoring of fungal infections.  The use of urea as a substance harmless to natural enemies may be beneficial in the integrated control of pestiferous soil arthropods.
