A Method for Generating Meloidogyne incognita Males

Daniel W. Snyder, Charles H. Opperman, David McK. Bird


A method for producing mass quantities of Meloidogyne incognita males free from other developmental stages was developed. Host plants were grown hydroponically to facilitate nematode harvest. Pruning stress was shown to cause a higher percentage of juveniles to develop as males vs. a no-stress control. Application of pruning stress in the first 48 hr post-inoculation was also shown to be more effective at driving male development than at later times.
