Competition for Aphid Prey between Different Lady Beetle Species in a Laboratory Arena

Table 5

Correlations between aphid consumption and prey discovery time for single and paired lady beetles in trials (𝑁=10). Each row represents the relationship between aphid consumption and prey discovery time for the species in the left column when it was alone or paired with the species in the first row of the table. Ct: Coccinella trifasciata, Cm: Coleomegilla maculata, Hc: Hippodamia convergens, Cs: Coccinella septempunctata, Ha: Harmonia axyridis, Hv: Hippodamia variegata, Pq: Propylea quatuordecimpunctata. Nonnative species are printed in bold font.
