Biological control of fig scale: From 67% to 100% of scale on twigs sampled in 1954 at colonization sites was found to be parasitized

R Doutt
Two small colonies of Aphytis “C,” a wasp parasite of the fig scale–Lepido-saphes ficus (Signoret)–released in the San Joaquin Valley, one at Merced and the other near Fresno, demonstrated what is almost an axiom in biological control work: if a parasite is destined to succeed, it will take hold immediately after an adequate release on susceptible hosts.
