Abstract | ||||
The occurrence and regulalion of ApheJenchoides besseyi, Christie, 1942 recovered from soaking either twenty grams straw or one hundred rice grains offour varieties i.e, Sakhia 101, Giza 177, 171 and Rehoo for 480r48an 96hrswas investigated under room ternperatur> (25 + 2"C). Results indicated th~t the population density of A. besseyl obtained every month after harvest from oaking rice grains or straw tested was higher than that of at harvest or pre-maturity stage. After harvest grains of Rehoo variety gave the highest numbers of A. besseyi, whereas, Sakhia 101 showed the least with values o( 57.0 or 76.4 and 33.8 or 43.~ Individuals when rice grains were soaked for 48 or 96 hrs, respectively.
