Grout, T.G., & Richards, G.I. 1991 Effect of Buprofezin applications at different phenological times on California Red Scale (Homoptera: Diaspididae).. Journal of Economic Entomology 84(6): 1802-1805.

Notes: Abstract: California red scale; important citrus pest in southern Africa; treatments applied at crawler emergence and midway between two peaks of crawler emergence in populations with either two or three cohorts; crawler emergence treatments significantly more efficacious in inter-emergence treatments only in dual-cohort populations during winter when the intercohort periods were longest.
