During the past 5 yr, Rhadopterus picipes (Olivier) has caused substantial losses in sales of plants in the largest nursery area of Louisiana. Some ornamentals in home lawns also have been heavily damaged. Most adults emerge from the soil during late Apr. through the middle of May. Soon after emergence, beetles begin feeding on new foliage. A few beetles emerge as late as Sept. After feeding for ca. 2 wk, the beetles mate and females move under leaf litter to oviposit. Females deposit an average of 150 eggs in clusters of 12–102. Larvae eclose in 9–11 days and burrow in the soil where they feed on roots. Injury caused by larvae has not been observed. Reduced shade, removal of leaf litter, and delay in time of outplanting significantly reduced feeding activity of beetles.
