Abstract

Ambient atmosphere; soil structures; flooding irrigation; fertilization and some agricultural practices were investigated for their effects on Red Palm Weevil (RPW) infestation. Thus, the aim of the present work was to study the effect of certain agricultural practices on the % of infestation of date palm trees by the RPW, Rhynchophorusferrugineus Olivier. Results show that the pruning of trees without dusting application by agricultural sulfur recorded a highest % infestation in the experimental area (desert and agricultural areas), while the pruning processes followed by dusting application of trees gave a lower percentage of infestation rate. Flooding the irrigation area resulted in a significantly higher % of infestation level, compared to desert area (non-irrigated). The RPW infestation rates in the experimental farm were observed in stem position of 0-50 cm which ranged between 45.3 to 48.28 (desert land, 2013) and between 48.32 to 55.21 (reclaimed area, 2014), while the percentage of infestation in the top recorded the lowest rate. On the other hand, all degrees of percentage of infestations by RPW in agricultural areas were higher than those investigated in desert areas. The ambient atmosphere surrounding the date trees is a very important factor affecting the biology and behavior of RPW adults, because of its effect on egg laying; hatchability and larval capacity to penetrate inside trunk. After pruning processes, the dusting application must be taken immediately.
