Blissus leucopterus
true chinch bug, chinch bug
Blissus leucopterus, commonly known as the true chinch bug, is a small hemipteran native to North America and the most frequently encountered species in the genus Blissus. Adults measure approximately 4 mm in length with distinctive black bodies, white wings bearing black triangular spots, and reddish legs. The species is a significant agricultural pest of turfgrass and grain crops, particularly corn, wheat, and sorghum, causing damage by sucking sap from stems and leaves. Populations thrive under hot, dry, sunny conditions, while heavy rainfall and high humidity promote fungal pathogens that suppress infestations.
Blissus occiduus
Western Chinch Bug
Blissus occiduus, the western chinch bug, is a phloem-feeding true bug (Hemiptera: Blissidae) that is a significant pest of warm-season turfgrasses, particularly buffalograss and zoysiagrass. The species exhibits strong host preference hierarchies, with buffalograss being the most preferred host followed by zoysiagrass, though it can survive and reproduce on a broad range of grasses including agronomic crops. Field studies have documented inconsistent control with neonicotinoid insecticides, with thiamethoxam showing particularly rapid degradation in buffalograss tissues compared to imidacloprid and clothianidin.

major
Blue Oat Mite, Winter Grain Mite
Penthaleus major, commonly known as the blue oat mite or winter grain mite, is a small earth mite in the family Penthaleidae. It is a significant agricultural pest of pasture grasses and grain crops, particularly oats, wheat, and barley. The species reproduces asexually through obligate thelytokous parthenogenesis and has a broad global distribution spanning multiple continents. Temperature strongly influences its development, with optimal population growth occurring around 12°C and no development possible below 6°C or above 24°C.
