Mortality of False Chinch Bug, Nysius raphanus (Howard), to Selected Insecticides

Resistant Turfgrasses for Improved Chinch Bug Management

Host preference of the chinch bug, Blissus occiduus

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 ...

Evaluation 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...

Bug Hunting with False Negatives

Safe data abstractions are widely used for verification purposes. Positive verification results can be transferred to the concrete system. When a property is violated in the abstract system, one still has to check whether a concrete violation exists. However, even when the violation scenario is not reproducible in the concrete system (a false negative), it may still contain information on possi...
