Bassino, B., & Bénassy, C. 1973 Résultats d'une lutte raisonée contre la Cochenille du mûrier en verger de pêchers. [Results of systematic control against the white peach scale in a peach orchard.]. La Defense des vegetaux 27(161): 160-165.

Notes: [Original title: Résultats d'une lutte raisonée contre la Cochenille du mûrier en verger de pêchers.] A spray programme which took into account the life histories of the scale Pseudaulacaspis pentagona, its parasite Prospaltella berlesei and other peach pests allowed the parasite to multiply at the expense of a host already depleted by the destruction each spring of some of its young larvae. The parasite population was able to withstand partial destruction each year as a result of the spray programme.
