Citrus Pests Key is intended to be used as a screening aid. The study was conducted by examination and sampling of whitefly adult populations on young shoots and catches as well as its parasitoid during a month period by counting the parasite and infested-live larvae.

Les ravageurs des agrumes showed remarkable variations in abundance indices and infestation rates of larvae and adults that depended on the growth flush in foliage and meteorological conditions of the region.

The woolly whitefly manifested three flight periods coinciding with three growth flushes of orange sap; in autumn towards the end of September followed by mid-November les ravageurs des agrumes the highest average abundance of 10 individuals per branch and a third flight period in mid-May.

Phases of growth flush seemed to have an effect on the temporal distribution of adults over the sampling period from July to June. Les ravageurs des agrumes for the incidence of natural enemies on whiteflies, despite their abundance, their impact was not optimum due to the large fluctuations in number of whiteflies.


Although the pest-parasitoid complex appears to be important in the orchard, the biological regulation exerted by C. An integrated approach is needed using additional natural enemies associated with the woolly whitefly.
