Reduction in the infestation with Phyllognathus excavates caused by S. carpocapsae and H. bacteriophora at the concentration of 4000 IJs/ml after eight weeks were100 and 70.0 %, respectively.

As for Rhynchophorus ferrugineus reductions in the infestation caused by S. carpocapsae and H. bacteriophora at the concentration of 4000 IJs / ml after eight weeks were 91.0 and 34.2 %, respectively. It was also clear that S. carpocapsae influence increased gradually in the course of the investigation time in opposite to H. bacteriophora . The tested EPNs S. carpocapsae and H. bacteriophora reduced the infestation with Phonapate frontalis by 84.7 and 39.9%, respectively at the end of the investigation course (8 weeks after treatment). The tested EPN S. carpocapsae and H. bacteriophora behaved with Lepidoptera insects oppositely with Coleopteran whereas H. bacteriophora surpassed S. carpocapsae in reducing infestation with Lepidoptera insects except with Ephestia calidella .

Treatments consisted of five varied bagging timings using kraft paper i.e., at spathe bagging 15, 30, 45 and 60 days after pollination compared with control (unbagging). Data were collected for fruit set (%), fruit drop (%), fruit yield (kg/ palm) and some of physicochemical quality parameters. Results revealed that bagging times affected all the parameters significantly. Maximum fruit set and fruit yield and best fruit quality and minimum fruit drop of two cultivars from bagging at spathes 30 days after pollination. Fruit quality improved the overall fruit physicochemical quality characteristics with maximum fruit length, fruit width, fruit volume, fruit weight, total soluble solids, total acidity and total sugars.
