Levitin, E., & Cohen, E. 1998 The involvement of acetylcholinesterase in resistance of the California red scale Aonidiella aurantii to organophosphorus pesticides.. Entomologia Experimentalis et Applicata 88: 115-121.

Notes: Laboratory toxicity bioassays using chlorpyrifos (Dursban) confirmed the notion that development of resistance is responsible for widespread failures to control the California red scale, Aonidiella aurantii by applying organophosphorus (OP) compounds in citrus groves in Israel.
