Document Summary
Predator is an organism that kills and consumes multiple prey individuals for food (e. g. a wolf); for fungus, creates a mycelium, and multiple capturer-mechanisms can capture nematodes. Most common are insects, like when they inject their eggs into a caterpillar. Predator fungus with mycelium with loopy traps: has glue (lectin that binds to a particular carbohydrate on the skin of nematodes) and a chemical attractant to draw nematodes. Eventually when there"s enough food, they produce tall conidiophores producing conidia; those spores have to carry with them enough food to germinate and produce traps before they can catch any more food. Here is haptocillium; in centre of picture are some dead nematodes and haptocillium is growing out of it. How it got into them initially: nematode swims and touches the parasitoid; nematode swims away, dies and is digested from inside out.
