Wu, M.L., & Liu, X.Q. 1994 [Repellent effects of some plant oils on Hemiberlesia pitysophila Takagi.]. Entomological Knowledge 31: 1, 28-30.

Notes: Margosa [Azadirachta indica] oil, Indian margosa oil and rubber tree [Hevea brasiliensis] seed oil had strong repellent effects (53.8-92.8%) on newly-hatched nymphs of Hemiberlesia pitysophila in 1-10 days after spraying. There were no significant differences between the species.
