This study aims to (i) delimit ladybird species through DNA barcodes and (ii) compare the abundance of different ladybird taxa from different crop management practices. A total of 2260 ladybirds were collected and barcoded resulting in 12 species representing four subfamilies (Coccidulinae, Coccinellinae, Epilachninae, and Scymninae). Three predatory species dominated and were top contributors to the dissimilarity average for different crop management practices, i.e., Coccinella transversalis, Micraspis discolor, and Cheilomenes sexmaculata. Even though the effect of different crop management practices on ladybird abundance was insignificant (Kruskal Wallis, p-value > 0.05), their diversity significantly varied across different practices (diversity t-test, p-value < 0.05). Organic monocrop resulted in a higher value of Shannon index (H’), and richness than other management practices. Furthermore, monocrops comprised higher ladybird diversity than multicrops. While the species assemblage was not distinct (ANOSIM, p-value > 0.05), a variation in assemblage composition and spatial distribution concerning the different crop management employed (NMDS, stress value = 0.12) was observed.

Yet, there is a lack of knowledge on the relationship between a diversity of functional plants found at the field scale and the dynamic of ladybird population. In this study conducted over three consecutive years, we investigated from early May to mid-August, the weekly abundance of predatory ladybirds on 15 functional plants and peach trees (Prunus persica) in a peach orchard agroecosystem in the Beijing Province of China. Seven plant species hosted 90% of the ladybird population throughout the study period.

The plant species were either at their seedling, blooming or fructification stage when hosting the ladybirds, suggesting that these lasts used the diversity of resources (prey, nectar and pollen of flowers and extra-floral nectar) offered at the agroecosystem level. The present results enrich the screening of functional plants supporting predatory ladybirds in perennial agroecosystems and emphasize the need to pay attention to the long-standing plants in the surrounding habitats.
