| feeding behavior comparison of soybean aphid (hemiptera: aphididae) biotypes on different soybean genotypes. | soybean aphids have become a serious pest of soybean, glycine max l. (merrill), since they were first detected in north america in 2000. three soybean aphid biotypes have been documented in the united states in the last 10 yr, but few studies have been done on their feeding behavior in the united states the electrical penetration graph is a convenient and successful tool to study the feeding behavior of piercing and sucking insects. this is the first attempt to study the feeding behavior differe ... | 2013 | 24224269 |
| crop residue and residue management effects on armadillidium vulgare (isopoda: armadillidiidae) populations and soybean stand densities. | in general, armadillidium vulgare (latreille) are considered nonpests of soybean [glycine max (l.) merrill], but changes in soil conservation practices have shifted the pest status of this organism from an opportunistic to a perennial, early-season pest in parts of central kansas. as a result, soybean producers that rotate with corn (zea mays l.) under conservation tillage practices have resorted to removing excess corn residue by using controlled burns. in a 2-yr field study (2009-2010), we dem ... | 2012 | 23156159 |
