Abstract

During 1978-79 four insecticides were tested against Cryptoph!ebia ombrode/ta (Lower) on macadamia at Nambour. Mean numbers of unmarketable nuts per tree were 1 0.5, 12.4, 19.5, 35.6 and 293.0 for 0.005 % permethrin, 0.05 % methidathion, 0.075 % acephate, 0.05 % omethoate and control treatments, respectively. All insecticides significantly reduced losses; permethrin and methidathion were significantly more effective than omethoate. Permethrin gave the longest protection.
