Four serious insect pests of citrus of Mainland China so far do not spread onto this Island. The Yanone scale was eradicated soon after its first discovery in Taiwan in 1935. Modern insecticides have been extensively and frequently used in citrus groves during last 15 years and most insect pests are now well under control. The citrus red mite which was formerly of no importance is however becoming more and more serious and most acaricides proved to be of little help against it. When applied on the trunk at the first sign of leaf burst and a 7-10 day interval of flushing, azodrin may control most species of aphids, mealy bugs, soft scales, armoured scales and stink bugs, as well as the leaf miner, psylla, cottony cushion scale and rust mite. No apparent side effects were noted during the 5 years’ operation in an experimental grove containing 1,000 citrus trees, meanwhile the activities of two predatory beetles in that grove appeared to be fairly effective in controlling the citrus red mite.
