Abstract

To examine the potential effect of an invasive coccinellid (Harmonia axyridis) on the resident community of coccinellids, we sampled predators and prey associated with organic Brassica oleracea production on 6 farms during 2 years in the Distrito Federal, Brasil and conducted a food acceptability trial to estimate niche breadth and overlap among the coccinellids. The data are in two files. The first is a community sample data set, with columns describing the sample characteristics (year, farm, sample period) and the summed counts of all macroinvertebrates found on 30 plants at each sample period, farm and year. There are 120 samples and 36 populations of macroinvertebrates in the data set. The second data set is the acceptability of 4 aphid prey species to 3 stages of 4 species of coccinellids. There are 15 replicates of the 48 treatments. The data also include the biomass of the predators at the end of the experiment. Farms have been de-identified, and the data can be used by anyone without any legal or ethical considerations. The authors request that anyone who reuses the data provide and acknowledgement of this in any publication as well as a citation to the originating study.
