Negative Impacts

 This lady beetle is an effective biological control agent of many different insect pests on a wide variety of ornamental and agricultural crops. Its population increases rapidly when prey are abundant, apparently because native ladybugs are unable to compete and because few natural enemies are present in the United States.

The multicolored Asian lady beetle is an efficient predator of aphids, as well as scale insects and psyllids. An adult is capable of consuming as many as 270 aphids per day, and a single larva can consume between 600 and 1,200 aphids during its development.

This species has greatly benefited the pecan industry by controlling the pecan aphid.
