| Résumé: | Date palm (Phoenix dactylifera L.) is a perennial
plant, the pillar of oasis’s ecosystem and a target to
pests attack. Distribution and the incidence of date
palm pests varied differently in each country, between
regions and date palm plantations. During
2017, a study was carried on 4,320 date palm trees in
113 farms in Figuig oasis (Morocco).
The objective of this survey was to document major
pests of date palm in Figuig oasis, their geographic
distribution in two types of cultivation systems (traditional
and modern plantations) and the sensitivity
of important cultivars ‘Assian’, ‘Aziza bouzid’ and
‘Boufeguous’ towards pest’s infestations.
The results revealed the presence of three major
arthropods species in Figuig oasis infesting date palm
with the first on the pest recorded on leaves Parlatoria
blanchardi Targ, (Homoptera) present largely in oasis,
the second pest on the fruits Oligonychus afrasiaticus
McGregor (Tetranychidae) mainly present in
modern plantations, and the third was Camponotus
thoracicus Fabricius (Hymnoptera), recorded for the
first time as date palm pest of stem and roots in both
traditional and modern plantations. The factorial
projection of the modalities confirmed the Chi-square
test results by showing independence between cultivars
and pests’ modalities. In fact, different groups
represent sensitivity between modalities of two cultivars
‘Aziza bouzid’ and ‘Boufeggous’ to Parlatoria
blanchardi and the other case of sensitivity can be
noted between ‘Assian’ and Oligonychus afrasiaticus.
The resultant maps from this study can be used to
identify high-risk areas for increased monitoring and
awareness of major date palm (Phoenix dactylifera L.)
