Host Preference Of The Chinch Bug, Blissus Occiduus, Thomas Eickhoff, Frederick P. Baxendale, Tiffany Heng-Moss
Department of Entomology: Faculty Publications
The chinch bug, Blissus occiduus Barber (Hemiptera: Blissidae), is an important pest of buffalograss, Buchloë dactyloides (Nutall) Engelmann and potentially other turfgrass, crop, and non-crop hosts. Choice studies documented the number of B. occiduus present on selected turfgrasses, crops and weeds, and provided important insights into the host preferences of this chinch bug. Grasses with the most chinch bugs present included the warm-season turfgrasses B. dactyloides, zoysiagrass, Zoysia japonica Steudel, bermudagrass, Cynodon dactylon (L.) Pers., and St. Augustinegrass , Stenotaphrum secundatum (Walt.) Kuntze. The other grasses tested, green foxtail, Setaria viridis (L.) Beauv, Kentucky bluegrass, Poa pratensis L., perennial …
Evaluation Of Cool- And Warm-Season Grasses For Resistance To Multiple Chinch Bug (Hemiptera: Blissidae) Species, Wyatt G. Anderson, Tiffany Heng-Moss, Frederick P. Baxendale
Evaluation Of Cool- And Warm-Season Grasses For Resistance To Multiple Chinch Bug (Hemiptera: Blissidae) Species, Wyatt G. Anderson, Tiffany Heng-Moss, Frederick P. Baxendale

Chinch bugs are common pests of many agronomic and horticulturally important crops and turfgrasses. The extensive overlap of plant hosts and geographic distribution of Blissus leucopterus leucopterus (Say), Blissus leucopterus hirtus Montandon, Blissus insularis Barber, and Blissus occiduus Barber underscores the importance of identifying resistant germplasm. Cool- and warm-season turfgrasses and sorghum, Sorghum bicolor (L.) Moench, were evaluated for resistance to chinch bugs in the Blissus complex, and the presence of multiple resistance was documented. Greenhouse studies established that B. occiduus-resistant (‘Prestige’, formerly NE91-118) and -susceptible (‘378’) buffalograsses, , Buchloe dactyloides (Nuttall) Engelmann, were susceptible to all other chinch …
