Biology and ecology of a mesquite twig girdler, Oncideres rhodosticta, in West Texas.
Twig girdler larvae may compete for space and food with other cerambycids and several species of bostrichids, and are attacked by parasites in the families Chalcedectidae, Pteromalidae, Eupelmidae, and Eurytomidae, as well as by predators in the family Cleridae. Expand
Germination of fourwing saltbush seeds: interaction of temperature, osmotic potential, and pH.
The interactive effects of temperature, osmotic potential, and pH on germination were evaluated with seed from 4 populations of fourwing saltbush from western Texas, suggesting that its seed may be adapted for germinating under conditions of limited moisture. Expand
