Moreno, D.S., & Luck, R.F. 1992 Augmentative releases of Aphytis melinus (Hymenoptera: Aphelinidae) to suppress California Red Scale (Homoptera: Diaspididae) in southern California lemon orchards.. Journal of Economic Entomology 85(4): 1112-1119.
Notes: Abstract: Releases of this aphelinid, timed in the spring to coincide with the presence of virgin adult female Aonidiella aurantii, reduced the percentage of infested fruits at season's end in two sets of southern California lemon orchards when compared with those in nonrelease orchards; percentage of infested fruit did not differ with the level of release; releases did not reduce scale densities on twigs or the number of males caught in traps baited with pheromone from this species; this is consistent with known preference for larger female scales. Keywords: biological control; males; pheromones.
