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

Table 1

Mean (± SE) aphid consumption (number of aphids), prey discovery time (minutes), and aggression delivered (number of occurrences) by seven lady beetle species during laboratory trials. The data were pooled for all trials conducted with a given species (see text for details). Means in each column followed by the same letter are not significantly different from each other (Tukey’s HSD tests, ). Nonnative species are printed in bold font.
