Biological Control
Biological control of gorse has been investigated since the 1920s. Seven different agents have been released in New Zealand. Results have been mixed, but in general neither the seed-feeding nor foliage-feeding insects are doing enough damage to be viable as a stand-alone control agent.

Famous quotes containing the words biological and/or control:
“Biological possibility and desire are not the same as biological need. Women have childbearing equipment. For them to choose not to use the equipment is no more blocking what is instinctive than it is for a man who, muscles or no, chooses not to be a weightlifter.”
—Betty Rollin (b. 1936)
“Have we any control over being born?, my friend asked in despair. No, the job is done for us while were sleeping, so to speak, and when we wake up everything is all set. We merely appear, like an ornate celebrity wheeled out in a wheelchair. I dont remember, my friend claimed. No need to, I said: what need have us free-loaders for any special alertness? Were done for.”
—Marvin Cohen, U.S. author and humorist. The Self-Devoted Friend, New Directions (1967)
