Cavalieri, V., Mazzeo, G., Tropea Garzia, G., Buonocore, E., & Russo, A. 2008 Identification of Planococcus ficus and Planococcus citri (Hemiptera: Pseudococcidae) by PCR-RFLP of COI gene.. Zootaxa 1816: 65-68

Notes: In this study, restriction fragment length polymorphism (RFLP) analysis of regions of mitochondrial gene cytochrome oxidase subunit I (COI) was used to distinguish populations of these two mealybugs associated with grapevine, namely . Planococcus ficus and Planococcus citri.
