Environmental factors affecting honey bees (Apis cerana) and cabbage white butterflies (Pieris rapae) at urban farmlands

Urban Farm DB summary

This study investigated how environmental features within and surrounding urban farmlands affected the abundance of Asian honey bees (Apis cerana) and cabbage white butterflies (Pieris rapae) in a megacity of China during winters. P. rapae abundance increased with local crop diversity but was strongly negatively associated with landscape-scale crop and weed covers. A. cerana responded positively to fine-scale flower cover, increased with local-scale weed cover, but decreased with increasing landscape-scale weed cover.
