The multiplication possibilities of an aphid ecotype from an artificial cedar stand (the Petit Luberon in the Vaucluse department) were studied from 1996 to 2000, in temperature-controlled chambers and by artificial infestation of young plants from various areas. The plants belonged to the four species of Cedrus and to two hybrid species: C atlantica x C. brevifolia, C atlantica x C libani. The three French C atlantica provenances showed a high susceptibility to C laportei. In contrast, the aphid never developed on a provenance of C brevifolia from Cyprus. One provenance of C. deodara from Afghanistan would resemble the susceptible provenances. Overall, 14 C. libani provenances of Turkish origin and four of Lebanese origin were compared in 1997 and 1998. The Turkish group was proved to be very heterogeneous. Some of these provenances were more susceptible than those of C atlantica. Others, originating from eastern areas (> longitude of 33 degrees) such as %22Aslankoy%22, were much less susceptible.

The multiplication possibilities of C. laportei on the two hybrid species were limited.

At this time, we have species with varying degrees of resistance to the aphid at our disposal. In France, C. brevifolia should be reserved for ornament.
