Measuring host finding capacity and arrestment of natural enemies of the cassava mealbug, Phenacoccus manihoti, in the field

Autor: Neuenschwander, P. Ajuonu, O.

In uninfested fields, 80 cassava tips were artificially infested with 0, 1, 2, 4, 8, 16, 32, or 64 third instars, and 20 or 100 eggs of cassava mealybug, Phenacoccus manihoti Matile‐Ferrero (Hom., Pseudococcidae). Another 80 uninfested tips served as a control. Tips were arranged in a circle of 2...
