Evaluation of the Effectiveness of Spirotetramat on the Diaspine Scale Parlatoria pergandii in Citrus Orchards

The control of Parlatoria pergandii (Comstock, 1881) was studied in citrus orchards at Belksiri (Gharb area), Morocco. Three concentrations Spirotetramat (T0 = 0 L/Ha, T1 0.625 T2 0.755 and T3 1 L/Ha) were applied to 4 ha Valencia late orchard (each dose for citrus). insecticidal evaluated on two stages larvae (L1 L2) P. three females, F1, F2, F3. Similarly, the rates parasitism by Aphytis hispanicus females different monitored evaluate impact this natural enemy. Results showed that more effective than females. Of 26.04% parasitized, 65.81% inhibited, only 8.15% intact after treatment period. larvae, 79.73% 20.27% survived Finally, our study highlights all tested product population pergandii. On other hand, a less negative parasitized with low concentration (0.625 compared high pesticide (T2 L/Ha L/Ha), especially female F2 Moreover, water table will be severe concentration.
