Method / resource Potential parasitism predicted actual parasitism with R2 of 0.84.
Mechanism Weevil larvae were more vulnerable on small-fruited pepper varieties because they developed closer to the pericarp.
Mechanism Larvae feeding in the pericarp of varieties with little placenta and seed were more vulnerable.

Intervention effect At 0 μM phosphorus, parasitism damage was 67% lower than at 20 μM.
Observation Cuscuta biomass was highest when both water and phosphorus availability were lowest.
Observation Cuscuta caused greatest soybean damage under 5 μM phosphorus, 5–15% WHC and high parasitism.
