Non-conventional 10 means of control (horticultural, microbiological, and local chemical treatments) were evaluated in an infested citrus orchard located at Tokh district, Qalubia govemorate during 1 and 2 successive years (December 2002 / to November 03 and/or 2003 / 04) against H. eruchtus The rate of reduction of infestation with winter pruning treatment averaged 40.53 and 59.32%, summer pruning treatment (17.80 and 23.29%), winter and summer pruning treatments (49.79 and 63.98%), fungal treatment (12.30 and 13.35%), bacterial treatment 19.67 and 10.87%), local spraying treatments (61.47 and 78.88%), local painting treatment (34.90 and 55.90%), winter and summer pruning and local spraying treatments together (78.15 and 91.30%), winter and summer pruning and local painting treatments together (68.42 and 82.30%), when applied for 1 and 2-successive years, respectively.
