Role of trichome density in cassava resistance to mealybug, Phenacoccus manihoti Matile-Ferrero was evaluated on the apex, the first expanded leaf and the stem in pubescent and glabrous cassava varieties. Pubescence significantly retarded the rate of settling and establishment of P. manihoti. The...

The aleyrodid Aleurodicus dispersus is reported from Nigeria. The first observation was made on cassava in early 1992 at several locations in Ibadan. A survey carried out in January 1993 revealed that several genera, many of them important food and ornamental crops, are food plants of the insect.
