Integrated pest management (IPM) practices that work for navel oranges may not be best for mandarins, suggests a new study in the Journal of Economic Entomology. Research by scientists in California’s mandarin-growing region indicates that IPM tactics for traditionally grown oranges may not be most effective for optimum mandarin production. The scientists noted, in fact, that “there is likely an overuse of pesticides in some mandarin species.” (Photo credit: Bodil N. Cass, Ph.D.)
