Remarks
- Systematics: Phenacoccus herreni is morphologically very similar to P. manihoti; however, in life the two species can be differentiated by the colour of the body, being light yellow in P. herreni and pinkish in P. manihoti. (Kondo, et al., 2022)
- Structure: Body contents of live adult female yellowish; body covered by mealy white wax, with short waxy filaments around body margin. Males are common. Phenacoccus herreni can be diagnosed by the following combination of features: 18 pairs of cerarii, each cerarius containing 2 enlarged lanceolate setae, except for some on head with 1–3 enlarged setae; antennae each 9-segmented; claws each with a denticle. (Kondo, et al., 2022)
- Biology: Living on stems, leaves and apices of cassava. The mealybug causes distortion to the growing tips (Cox & Williams, 1981). Jatropha gossypiifolia L. (Euphorbiaceae), a plant species known to contain proteins toxic to insects, exhibited insecticidal properties to P. herreni. The toxic compounds consisting of proteins around 101.02 kDa appeared to be mostly located in the mature leaves. Further studies are needed to identify the proteins and to ensure that they are not toxic to mammals. (Calatayud, et al., 2011)
- Economic Importance: Bento et al. (1999) and Bento et al. (2000) discussed the damage caused by Phenacoccus herreni to Manihot esculenta in north-eastern Brazil, and reported on successful introduction of three species of hymenopterous parasitoids. Hountondji et al. (2002) found that Phenacoccus herreni was not susceptible to Brazilian isolate of the entomopathogenic fungi Neozygites floridana.
