Spatial distribution of Geotrogus deserticola at Tissemessilt area in North of Algeria
Archives of Applied Science Research(2012)
摘要
This study describes the allocation and distribution of Geotrogus deserticola beetle pest of cereals at the Province of Tissemlesilt (North of Algeria). The examination of infestations revealed seven towns infested on a total of 10, the most heavily infested towns are: Laayoun, Tissemessilt, Ouled Bessam, Khemisti, Maacem, Ammari and Sidi Boutouchent. Moreover, the common Lardjem, Sidi Abed and Beni Chaib, showed no infestation by white grubs. As for the spatial distribution of this pest, the horizon H1seems to be the profile of the most sought by this insect. Strong correlations have been brought out between the biometric variables of this pest in particular its total size, its length and that of head capsules. However, no correlation could be found between this distribution and the physicochemical parameters analyzed.
