NEMATOLOGY 100
Laboratory Exercise 2
Rev. 09/27/2008
Purpose: Nematode Anatomy and Morphology: Form and Function:
1. Slide presentation of anatomical and morphological features.
2. Movie of mating behavior and copulation in the nematode Pelodera.
3. Live specimens are provided from soil around the following plants and locations.
a) Draw the stoma and stoma armamentation for:
a tylenchid nematode (Order Tylenchida)
a dorylaimid nematode (Order Dorylaimida)
a mononchid nematode (Order Mononchida)
a rhabditid nematode (Order Rhabditida).
Consider the feeding behavior of these forms.
b) Draw the female reproductive tract; indicate whether the arrangement of uteri is
prodelphic, opisthodelphic, amphidelphic.
c) Draw representative male reproductive structures, including spicules and gubernaculum, caudal alae.
4. Use sieving and decanting with the Baermann funnel to separate nematodes from soil in your personal samples.
