“Lygus bug, Lygus hesperus Knight, and beneficial insect populations ( Orius sp., Geocoris spp., and Nabis spp.) were quantified in alfalfa strips, which were interplanted within cotton fields”

“Lygus bug levels in the strip-cut treatments were low in the newer alfalfa growth (averaging 41.8 per 1.9 m 2 ) and only slightly higher in the older alfalfa growth of the 28-d strip-cut treatment (averaging 65.3 per 1.9 m 2 )”
Coccinellids fed greenbugs from both resistant sorghum hybrids had an increased time from egg eclosion to pupation compared with the susceptible hybrid.
“Two resistant sorghum, Sorghum bicolor (L.) Moench, hybrids, Dekalb DK-41 Y and DK-59E, which exhibit antibiosis to green bugs, Schizaphis graminum (Rondani), were tested along with a greenbug-susceptible hybrid, Horizon 101G.”

“Plant antibiosis reduced larvalpupal survival and increased the amount of time from egg eclosion to pupation in coccinellids that fed on greenbugs from both of the resistant hybrids compared with the susceptible hybrid”

“25 seeds of each of six weed species, including velvetleaf, wild mustard, yellow foxtail, common lambsquarters, redroot pigweed, and hairy galinsoga, were placed in the field”
e2
“The predominant invertebrate seed predator across all entry points of four cropping systems was a ground-dwelling carabid beetle, Harpalus rufipes, which was more abundant in vegetated treatments, particularly red clover, compared with treatments recently tilled and planted to a fall cover crop”
e3
“In the absence of vertebrates, H. rufipes activity–density was positively correlated with mean seed predation in 2002 (Spearman ρ = 0.489; P < 0.001) but not in 2003 (Spearman ρ = 0.090; P = 0.504)”
