Abstract
The relative attractiveness of various baits to the oriental fruit-moth, Laspeyresia moles/a, is discussed. The results correlate very well with those made by the writer in 1925. The possibilities of weak acids, volatile oils or their ingredients, fermenting and non-fermenting baits are discussed. While fermenting baits give, on the whole, larger catches, the non-fermenting baits have a longer period of activity and may prove more practical for control purposes. The results clearly indicate that a more attractive bait must be had before adequate control can be expected. Orchard tests, where the infestation is not high, show a reduction of nearly 30% wormy fruit.
