On the photos, there are two different nematodes: a male and a female. The general criteria and observations are indicated directly on the photos. Here is a comprehensive list of the main characteristics for Aphelenchoides fragariae: - Length in mm: 0.62-0.895 (female) - Head shape: Slightly « offset » and lips prominent wider than the body - Stylet length in µm: 10-13 - Stylet cone: 50 % - Median bulb oval/round - Nerve ring behind the muscular median bulb - Excretory pore at or just behind the nerve ring - Length of the post-vulval sac in female: more 50% of the distance betwenn the vulva and the anus - Position of the vulva relative to the anterior end, expressed as a % of the body length in female: 66.5-72.2 - Total body length divided by the maximum body diameter in µm (a): 46.2-64.5 (female) - Total body length divided by tail length in µm (c): 13.4-20.3 (female) - Number of lateral lines: 2 (sometimes 4) - Shape of tail: conoid - Shape of mucro: Single central spine (sometimes sin mucro)
