Kozár, F., & Konczné Benedicty, Z. 1996 [New data on the swarming of San José scale [Quadraspidiotus perniciosus (Comstock, 1881) Hom.: Coccoidea] males and scale parasitoids.]. Növényvédelem 32(10): 499-506.

Notes: Value of pheromone traps in studying flight of San José scale males, even at low individual densities; traps also caught adults of endoparsitoid Encarsia perniciosi; Epidiaspis leperii (red pear scale) and the ectoparasitoid Aphytis proclia also occurred in these orchards; planting of nectariferous plants failed to increase density of parasitoids.
