| الوصف: | International audience ; Three control methods were applied against the white scale of the date palm. Physical struggle with the buckling led to a mortality rate of 92.2 mealybugs and seems to be most effective. Chemical control using insecticides caused mortality percentages of 73.2 and 80.0 according to the plot. Biological control using beetles resulted in mortality percentages of 18.1 and 19.7. However, we found that the physical and chemical treatments caused significant mortality of auxiliary (78.8 to 89.4%). However, the biological method preserved the useful fauna. The use of Trichogramma in the region of Ouargla with releases of Trichogramma cordubensis made to fight moth in palm dates, showed interesting efficacy. Indeed, the chalcid, absent from the field before the release caused the percentage of egg parasitism of the moth varies from 47 to 64% depending on the trees following the release. It appears certain that a larger number of Trichogramma released into an entire parcel would allow the rate of infestation of dates by Ectomyelois ceratoniae to drop significantly. The Boufaroua Oligonychus afrasiaticus is a mite that stings the dates in which dry end of maturity and become unsuitable for sale and human consumption. Significant economic losses are then recorded. The most spectacular damage was noted on the 'Deglet Nour' high market value. Biological treatments using the ladybug local Stethorus punctillum, carried on more or less infested trees, led to relatively large predatory efficiencies. |
