Identification of Meloidogynids

  • Jonathan D. Eisenback
Part of the Nato ASI Series book series (NSSA, volume 7)


Often two people look at the same nematode specimen at low magnification with a dissecting microscope and see very different pictures. The observer with much experience with a certain group of nematodes sees many details because those features have been examined many times before and frequently at higher magnifications. Whereas, the observer with little experience may not be familiar with certain morphological characters, and therefore he may be unable to ascertain them at low power. The approach to the identification of the meloidogynids in the present chapter is to recognize certain promorphs from characters that can be seen with a dissecting microscope, and to identify nests of species from characters visible with a light microscope. It is hoped that the characters used for the identification of promorphs will be readily visible by observers that are not so familiar with the meloidogynids.
