This is the message from Mark Mazer that has come in blank:

For a cool greenhouse in NJ to have an infestation of brown citrus?
aphids at his time of year is an indication,
in my experience, of too much nitrogen fertilizer and that a systemic
insecticide application in the entire greenhouse might be prudent.
