Abstract
This study was conducted during 2008 season in one of Abu-alkhasib orchards to study the effect metaxenic of four different pollen grain cultivars (Gannami Akhder, Gannami Ahmer, Khikri Werdi, and Khikri Adee) on two females cultivars (Hillawi and Sayer) and infestation by lesser date moth Batrachedra amydraula Merck and dust mite
Oligonychus afrasiaticus Mcg. Moisture content of fruits and was and phenolic compounds were calculated.
Results showed that fruits pollinated by Gannami Akhder caused the lest infestation and less fruit dropping by lesser date moth was 5.30% and less infestation dust mite was14.08 mite/fruit. Fruit that pollinated by Gannami Ahmer recorded less infestation percentage by dust mite which was 24.4%. The highest percentage of infestation and fruit drooping by lesser date moth came form fruit pollinated Khikri Adee which was 13.5% and highest infestation percentage and infestation severity by dust mite 40.7% and 18.83 mite/fruit respectively.
Sayer cultivar had less fruit dropping by lesser date moth and less infestation by dust mite comported with Hillawi cultivar, fruit that pollinated by Gannami Akhder were highest in strand weight 81.56gm whereas, fruit pollinated by Khikri Adee had strand less weight was 46.36gm. Fruit strand weight of Gillawi was higher than that of Sayer (76.30, 62.17 gm)respectively.
Moisture content, waxes, and phenolic compound were varied according to the pollination sources and female cultivars.
