Lin, Y., Peng, Y.K., & Chen, S.Z. 1997 Studies on the bionomics of Aulacaspis citri Chen and its control.. Journal of Southwest Agricultural University (Nanchong, Sichuan, China) 19: 442-446.

Notes: Aulacaspis citri is an important scale insect infesting Citrus orchards in Sichuan, China. In 1987-95, systematic field sampling was combined with indoor feeding experiment to study its biological characteristics. Five generations of the pest were found to occur in one year with wide overlap of the generations. Telsimia emarginata, Cryptolaemus montrouzieri, Pseudoscymnus kurohime, Chilocorus kuwanae, C. nigritus (C. nigrita), Chrysopa sinica (Chrysoperla nipponensis), Chrysopa formosa, C. shansiensis (Chrysoperla carnea) and Aphytis sp. were identified as natural enemies, but their predatory rate was low, resulting in poor effectiveness of biological control. Thorough removal of bryophytes and spraying the tree crowns with contact or systemic insecticides to control overwintering larvae and adults are recommended as the key measures for control.
