Figure 4. Mealybug abundance and subsequent yield parameters for two cassava varieties under an exclusion cage assay at Rayong, Thailand.

Figure 4

Six weeks after inoculation, mealybug abundance (n = 16; mean ± SE) is compared between treatments for two common varieties (R72, KU50), and is significantly higher under ‘full cage’ conditions (i.e., exclusion of natural enemies, incl. A. lopezi), as compared to ‘sham cage’ and un-caged controls (ANOVA, F2,45 = 50.289, P < 0.001 for R72; F2,45 = 9.807, P < 0.001 for KU50). For each treatment, fresh root yield is determined at time of harvest, on a 12-month old crop.
