Effects of Leaf-Footed Bugs on Mesquite Reproduction

Abstract

Leaf-footed bugs, Mozena obtusa Uhler, were observed feeding on immature mesquite pods in the Rolling Plains of Texas. A sleeve cage study, using various population densities of these insects, showed that their feeding significantly increased the abortion of immature mesquite pods while decreasing the dry weight of pods and seeds and the germination percentage of seeds. Seedlings from seeds fed upon by this insect were significantly smaller and less vigorous than those from bug-free seeds. This insect may limit the reproduction of mesquite and may offer a possibility for the utilization of a native insect for the control of a native weed.
