Rodolia cardinalis is a species of ladybird beetle that is widely known for its ability to control populations of the cottony cushion scale insect. Some commonly used synonyms for this beetle include the Vedalia beetle, Rodolia ventralis, and Novius cardinalis. These species all belong to the same family and share many similar physical and behavioral characteristics. While their names may vary, they all serve an important purpose in protecting crops from harmful pests. The use of these beetles as natural predators has become an increasingly popular alternative to chemical pesticides, providing a safer and more sustainable approach to pest management.
