Pineapple scale investigations
1955
Brimblecombe, A.R.
Studies on seasonal breeding and control of Diaspis bromeliae (Kerner) were conducted at Rochedale, near Brisbane. Control trials have shown that a mixture of white spraying oil and nicotine sulphate (16-1-640) gave only a small kill of insects and dispersible BHC (0·1%) and chlordane emulsion (0·5%) were ineffective. Parathion (0·1 %) showed some promise but results from the lower concentration (0·025%) were inconclusive. The problem of chemical control therefore requires further investigation when adequate populations of the insect appear.
