چکیده
Blissus occiduusBarber has emerged as an important insect pest of buffalograss,Buchloë dactyloides (Nuttall) Engelmann, in Nebraska. This research evaluated selected buffalograss germplasm for resistance to B. occiduus. Eleven buffalograss selections were screened for chinch bug resistance in three greenhouse studies and two Þeld evaluations. Based on chinch bug damage, NE91Ð118, ÔTatankaÕ, ÔBonnie BraeÕ, and ÔCodyÕ were rated highly to moderately resistant. These four buffalograsses exhibited minimal damage, even though all were heavily infested with chinch bugs. NE84-45-3 and Ô378Õ were highly susceptible to B. occiduus. Field evaluations conÞrmed chinch bug resistance ratings under Þeld conditions. NE91Ð118 displayed high levels of resistance in the Þeld screening evaluations, whereas Cody and Tatanka showed moderate levels of resistance, and 378 was highly susceptible.

متن کاملBuffalograss germplasm resistance to Blissus occiduus (Hemiptera: Lygaeidae).
Plant germplasm collections may offer genetic variability useful in identifying insect resistance. The goal of this project was to evaluate buffalograss genotypes [Buchloë dactyloides (Nutt.) Engelm.] for resistance to the chinch bug, Blissus occiduus Barber (Hemiptera: Lygaeidae), and to relate resistance to ploidy level, chinch bug number, and pubescence. Forty-eight buffalograss genotypes fr...
متن کاملTurfgrass, crop, and weed hosts of Blissus occiduus (Hemiptera: Lygaeidae).
Blissus occiduus Barber is an important pest of buffalograss, Buchloë dactyloides (Nuttall) Engelmann, turf. No-choice studies documented the susceptibility of selected turfgrasses, crops, and weeds to B. occiduus feeding. Highly to moderately susceptible grasses included buffalograss; yellow Setaria glauca (L.) and green foxtail Setaria viridis (L.); Kentucky bluegrass, Poa pratensis L.; peren...
متن کاملEvaluation of cool- and warm-season grasses for resistance to multiple chinch bug (Hemiptera: Blissidae) species.
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 a...
متن کاملChinch bug (Hemiptera: Blissidae) mouthpart morphology, probing frequencies, and locations on resistant and susceptible germplasm.
Chinch bugs are common pests of many agronomic and horticulturally important crops and turfgrasses. Previous research has indicated that some grasses exhibit resistance to multiple chinch bug species, whereas others are resistant to only one species. The objectives of this research were to document differences in the probing frequencies and locations among Blissus species as well as differences...
