“…Wildflower plantings also can be used to promote biological control of pest lepidopterans in cabbage fields (Pfiffner et al 2009) and potentially contain more beneficial predatory arthropods than do turf grass plots (Braman et al 2002). Additionally, decreased aphid abundance correlated with increased aphid predators in European crop fields that contained adjacent wildflower strips (Tschumi et al 2016, Hatt et al 2017b, Toivonen et al 2018.

Intensive agriculture has led to a reduction of overall biodiversity and ecosystem services such as pollination and biological control. To offset these economic losses, many farmers are planting native wildflowers to enhance flowering plant diversity and augment pollinator and other beneficial arthropod populations on their farms. In this study, we examined arthropod communities in Florida (USA) within wildflower plots and fallow control plots, which were primarily composed of grasses. Significantly more herbivorous insects, predatory arthropods, and pollinators were found within wildflower plots than in fallow control plots. We also implemented pollinator surveys at flowering plants. These surveys highlighted numerous plant–pollinator interactions within wildflower plots, supporting the idea that some native wildflower species are more attractive to pollinators than are others. Nevertheless, utilizing diverse flowering plants for wildflower plots may support a wide diversity of beneficial arthropod species, including native bees. Our results suggest that wildflower plantings in Florida can be a successful management tool to harbor increased overall plant and arthropod diversity (including native pollinators and other beneficial arthropods) within intensive agricultural areas.

“…Recent studies have shown that sowing WFS adjacent to crops enhances biological control of insect pests due to an increased abundance of natural enemies (Tschumi et al 2016;Hatt et al 2017a;Toivonen et al 2018). Indeed, generalist predators such as hoverflies (Diptera: Syrphidae), ladybeetles (Coleoptera: Coccinellidae) and lacewings (Neuroptera:…”

In agricultural fields, wildflower strips can be sown to enhance conservation biological control of insect pests. However, issues remain regarding the composition of flower mixtures to effectively attract and support large communities of natural enemies. Trait-based approaches are promising for this purpose. In the present study, conducted in an agricultural field of Belgium in 2014 and 2015, 15 flower mixtures were considered to explore the relation between the abundance of trapped generalist predators (i.e., lacewings [Neuroptera: Chrysopidae], ladybeetles [Coleoptera: Coccinellidae] and hoverflies [Diptera: Syrphidae]) and the community-weighted means of seven flower traits. Through a redundancy analysis, it was found that the presence/absence of flower ultraviolet pattern and the morphology of the corolla (that determines the accessibility of floral resources) were the traits that significantly affected the abundance of the generalist predators in the flower mixtures. The ladybeetles Harmonia axyridis and Propylea quatuordecimpunctata as well as the lacewings Chrysoperla carnae were more abundant in mixtures with a high cover of flowers showing an ultraviolet pattern, while the opposite was observed for the ladybeetle Coccinella septempunctata. As for hoverflies, Episyrphus balteatus and Eupeodes corollae were more abundant in mixtures with a high cover of flowers with open nectar. These results bring new knowledge regarding how a range of natural enemy species reacts to flower cues in diversified plant communities and should help in elaborating flower mixtures that enhance conservation biological control.
