Abstract:

During the present study three rice pest species i-e Oxya velox (Fabricius, 1787), Oxya hyla hyla (Serville, 1831) and Hieroglyphus nigrorepletus  (Bolivar, 1912) were treated with three  Aspergillus  species under laboratory condition. It was observed that infestation of Aspergillus cause significant reduction in the feeding and over all faeces production per insect  i-e (F.  (0.75)= 13.09, F.  (0.81)= 14.84, F. (0.79) =13.09 & F.   (1.89)=04.36  P<0.05) for Oxya velox,  (F. (0.57)=  0.96,  F. (0.72)= 13.09 , F. (0.84)= 14.84  & F. (1.71)= 0.436  P<0.05) for O.hyla hyla and  (F. (0.98)= 16.58 , F.  (1.08)= 0.262,  F.  (0.77)= 13.09 & F.  (1.41)= 0.262 P<0.05) for H.nigrorepletus when treated with three pathogenic fungi and control respectively. Individual analyses for each date revealed that, generally, mean faeces production per insect decreased with dose, with controls significantly higher than the treated populations.
