Systematic Parasitology, 1981
Polymorphism has been defined by Ford (1953, 1956) as ~the occurrence together in the same habitat at the same time of two or more discontinuous forms of a species, the rarest of which is too frequent to be maintained merely by recurrent mutation'. There has been little attempt to apply this definition to nematodes of ruminants.

In their classic book “An Introduction to Nematology” Chitwood & Chitwood (1950) wrote (1): “Having briefly considered the history of general nematology, the question naturally arises, “What is a nematode?”. In answering this question it is necessary first to designate a nematode as a triploblastic, bilaterally symmetric, unsegmented, non-coelomate

The enduring stages of entomopathogenic nematodes of the genera Steinernema and Heterorhabditis are infective juveniles, which require a high humidity and sufficient ventilation for survival. Formulations must account for these requirements. Nematodes may be formulated inside the insects in which they reproduced or they need to be cleaned and mixed ...
