Summary

Climatic factors have an important influence on the efficiency of hymenopterous parasites of Coccids.

Significant differences were observed in the rate of parasitism ofPseudaulacaspis pentagona Targ. by its natural enemies in different orchards or on different trees of the same orchard.

In order to investigate this phenomenon, experiments were designed in which the position of parasitized hosts on the bough was taken in consideration.

Analysis of host and parasite populations on the different parts of a bough show that the control byProspaltella berlesei How (Hym. Aphelinidae) is better on the shaded side; similar experiments have been undertaken withP. perniciosi prior to colonisation of this species for the Biological Control of the San José Scale.
