The effects of cultural controls on the major date palm borer pests, including Oryctes elegans, PseudophilusÂ testaceus and Microcerotermes diversus were studied by applying cluster-sampling method. Macheak method wasÂ used for estimating pest infestation and key pathology of date palm borer pest injury was used for distinguishingÂ their injuries. Cultural management factors included in the study were tillage, fertilization, irrigation, pruning,Â bunch covering and bunch arrangement. Data were analyzed by multiple regressions. Results showed that tillage,Â leaf pruning, petiole pruning and sucker removal had suitable effects in decreasing the date palm borer pestÂ infestations. The cumulative effects of cultural factors were calculated. Results showed that petiole pruning,Â tillage, leaf pruning and sucker removal had the highest rate of control,respectively. Petiole pruning is the mostÂ effective factor in reducing the severity of injuries caused by the borer pests, viz., termites, horned beetle and longÂ antennae beetle. Tillage practices and leaf pruning had the greatest effect in reducing termite, long antennae andÂ horned beetles, respectively. Sucker removal operations had the greatest effect in reducing the severity of injuriesÂ of horned and long antennae beetles in date palm trees.
