Smith, K.M., Smith, D., & Lisle, A.T. 1999 Effect of field-weathered residues of pyriproxyfen on the predatory coccinellids Chilocorus circumdatus Gyllenhal and Cryptolaemus montrouzieri Mulsant.. Australian Journal of Experimental Agriculture 39: 995-1000.

Notes: These coccinellids are key predators of mealybugs and scales of citrus. Pyriproxyfen is strongly insecticidal to diaspid scale insects including red scale, Aonidiella aurantii and coccid scales such as Florida wax scale, Ceroplastes floridensis.
