| comparative allozyme analysis of oriental migratory locust locusta migratoria manilensis from two breeding areas in north china. | the allozyme analysis using horizontal starch gel electrophoresis was employed to compare the genetic structure in the population of oriental migratory locust locusta migratoria manilensis from two breeding areas, beidagang(tianjin) and huanghua(hebei). the two areas are adjacent but with distinct ecological features, with the recorded locust outbreaks and migration. the zymograms showed that among nineteen loci four (mdh-1, pgm, adk and g3pd) showed extremely low variability level with the freq ... | 2002 | 12645258 |
