Effect of 4 fixatives (4% formalin, FA 4:1, FP 4:1 and TAF) and 3 dehydration techniques (glycerol-ethanol method, rapid lactophenol method and rapid method to glycerol) on morphometrics of Helicotylenchus astriatus was studied. Sixteen out of 20 parameters were found to be significantly altered. However, ratio b, V%, width of stylet knobs and distance from base of the stylet to DGO remained highly stable.
