Abstract

Several introduced clones of St. Augustinegrass, Stenotaphrum secundatum (Walt.) Kuntze and S. dimidiatum (L.) Brongn., from the Republic of South Africa, Tanzania, Zimbabwe, and Malagasy Republic exhibited high levels of resistance (antibiosis > 'Floratam', a resistant cultivar) to the southern chinch bug, Blissus insularis Barber. Resistance of 37 Stenotaphrum clones was evaluated on the basis of mortality of field-collected adult chinch bugs confined for 7 days with grass stolon terminals in plastic bags. Only polyploid St. Augustinegrasses were antibiotic to B. insularis. Resistance was found in both Old and New World clones, but not all polyploid St. Augustinegrass clones were resistant to the southern chinch bug.
