Hairy chinch bug (Hemiptera: Lygaeidae) damage, population density, and movement in relation to the incidence of perennial ryegrass infected by Neotyphodium endophytes.

Buffalograss 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...

Development of Resistance in Southern Chinch Bugs (hemiptera: Lygaeidae) to the Insecticide Bifenthrin

Evaluation of Buffalograss Germplasm for Resistance to <i>Blissus occiduus </i> (Hemiptera: Lygaeidae)

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, ÔBo...

The Fatty Acid Compositions of Phospholipids and Triacylglycerols from Two Chinch Bug Species Blissus leucopterus leucopterus and B. iowensis (Insecta: Hemiptera; Lygaeidae) Are Similar to the Characteristic Dipteran Pattern

1. The fatty acid compositions of phospholipids and triacylglycerols prepared from whole chinch bugs Blissus leucopterus leucopterus and B. iowensis were analyzed. 2. The fatty acid profiles from these insects are different from those from all other insect groups so analyzed, except most Diptera. 3. The major components include 16:0 and 18:0, high proportions of 16:1 and 18:1 and low proportion...
