The laboratory bioassays showed the frozen stored Rhynchophorus polyhedrosis virus (FSRPV) and newly extracted one from died red palm weevil, Rhychophorus ferrugineus (oliv.) (RPW) collected from the field. The FSRPV was stored for 18 months under -4 o C. The newly extracted Rhynchophorus polyhedrosis virus (NERPV) was used for contamination of laboratory reared larvae of RPW at different ages in comparison of the pathogenicity between FSRPV and NERPV. The infected larvae were bioassayed and LC 50 and LT 50 values were determined. The range of LC 50 for NERPV was from 2.6x10 7 to 4.0x10 7 Polyhedra Inclusion Bodies (PIBs) /100 g diet, while the LC 50 for FSRPV ranged between 3.3 to 3.8x10 7 PIBs/100 g diet. The range of LT 50 for NERPV was from 2.4 to 24.3 days while it was from 3.2 to 25.9 days for FSRPS.

In season 2005 data indicated that the percentage of infestation caused by Aphis gossypii ranged from 10.11 to 59. 21% with an average of 31.34% and the percentages of parasitism ranged from 1 to 2% with an average of 0.25%. In season 2006 data indicated that the percentage of infestation ranged from 11.59 to 76.25% with an average of 34.18% and the percentages of parasitism varied from 1 to16% with an average2.25% .
