Abstract
DDT, TM-1, and parathion were effective in control, but the last had a short residual life. Chlordane, aldrin, dieldrin, benzene hexachloride, methoxychlor, and lead arsenate were not effective. Sprays at the peaks of moth flight for control of the 1st and 2d broods were more effective than similar sprays for the 2d and 3d broods, and equally as effective as sprays applied for control of the 1st, 2d, and 3d broods.
