Re: [compost_tea] Nematodes



I can not resist a comment like this, "Does egg hatch rate as reporduction?"
Yes.After all without this step it is only fertilization. It is getting the viable eggs to the hatch that most of the female nematodes resources are used for. She feeds to grow eggs, get them fertilized, and lay them in the best environment she can to ensure the hatch is successful. Assuming the concept of genetic perpetuity is viable then reproductive success is counted in numbers of offspring able to grow and reproduce in turn.

Nematodes do not reproduce in compost tea.  If a female has laid eggs in the soil or compost, all those eggs hatch, typically, in the compost tea however.   So, you can go from a few nematodes per ml of tea, to hundreds, not because the nematodes go throug ha life cycle, but because egg hatch occurs.  Does egg hatch rate as reporduction?  Interesting question.  Not really reproduction, but it is an increase in living nematode numbers per gram of material.
