text: what are some names of natural insect-killing fungus' that do not need human application? i was reading a life science book from 1995 in my highschool class. i have to do a project to bring my grade up. the book is called "exploring life science." published by prentice-hall,inc.,englewood cliffs,new jersey 07632. the description of the fungus from book: a speck of dust lands on the back of an ant. but this is no ordinary dust-it is alive! tiny glistening threads emerge from the dust and begin to grow into the ant's body. as they grow, the threads dissolve the ant's tissues. the threads absorb the dissolved tissues and use the energy from them to spread further into the ant's body. within a few days, the ant's body is little more than a hollow shell filled with a tangle of the deadly threads. then the threads begin to grow up and out of the dead ant,winding together to produce a long stalk with a knobby lump at it's tip.the stalked structure releases thosands of dustlike spores,which are carried by the wind to new victims. cordyceps sps. often have a liking for a particular insect, insect pupae (or truffle)
