Calatayud, P.A., Boher, B., Nicole, M., & Geiger, J.P. 1996 Interactions between cassava mealybug and cassava: cytochemical aspects of plant cell wall modifications.. Entomologia Experimentalis et Applicata 80: 242-245.

Notes: Paper presented at the Ninth International Symposium on Insect-Plant Relationships held on 24-30 June 1995 in Gwatt, Switzerland; cytochemical evidence is presented that pectinesterase found in salivary secretions of Phenacoccus manihoti is associated with the degradation of middle lamellae of cassava.
