TOXIC EFFECTS OF SPINOSAD (BIOINSECTICIDE) ON LARVAL INSTARS OF DATE MOTH ECTOMYELOIS CERATONIAE (LEPIDOPTERA, PYRALIDAE) UNDER CONTROLLED CONDITIONS

21710

Due to the catastrophic consequences of the massive application of pesticides, scientists have been finding less harmful methods. In this context we conducted our work to explore the larvicidal activity of Spinosad on the instars larvae of Ectomyelois ceratoniae, which is the most important and dangerous pest of date palm in the world and particularly in Algeria. The study of the toxic effect of Spinosad on the mortality of the first larval stage revealed that the concentrations used were significantly and positively correlated with mortality adjusted for different durations of exposure of larvae to the bio-pesticide (100.00% with the concentration 100 ppm). The study of demographic parameters for individuals resulting from the larvae treated by four amounts of Spinosad, showed that this bio-pesticide decreases the female fertility and the fertility of eggs.
