Abstract
The aim of the present work was to study the Effect of certain agricultural practices on infestation of date palm by the red palm weevil (RPW)Rhynchophorus ferrugineus (Oliv.). Results showed that palm tree pruning without dusting with agricultural sulfur showed the highest infestation rate while, pruning of date palm and dusting with agricultural sulfur resulted in lower infestation rate. Flooding irrigation resulted in significantly higher infestation of date palm by RPW compared to dripping, which showed lower % infestation. The RPW infestation rates in date palm plantation were maximum in stem position of 0-50 cm. Meanwhile the lowest infestation rate was at the date palm top (growing area).Data also indicated that about 75%of date palm infestations were found at the first meter from the ground. The most susceptible date palm cultivars to RPW were seedling and Zaghloul followed by Samany and Hayany while the least susceptible cultivar was Amhat.
