Effect of infestation with acaridid mite, Tyrophagus putrescentiae (Schrank) on germination rate of maize grains

Abstract

The infestation of maize grains with the harmful acarid mite, T. putrescentiae at the laboratory was conducted after 3, 6 and 9 months. The number of normal, abnormal and analyzed maize grains was conducted. The infestation of maize grains with the harmful acarid mite, T. putrescentiae at the laboratory was conducted after 3, 6 and 9 months. The numbers of normal, abnormal and analyzed maize grains were conducted for 50 grains. Generally, it was noticed that the number of normal maize grains increased with decreasing the number of mites infested to grains and also with decreasing the time of infestation, while the number of abnormal maize grains increased with increasing the number of infestation mites and also with increasing the time of exposure to mites.
