SUMMARY Observations on the biology of the plum fruit moth, Laspeyresia funebrana (Treits.), in an orchard near Cambridge, England in 1967 showed that only one main generation occurred, with a partial second generation in late summer. Eggs of the first generation were laid between 16 June and 8 August, with between one and nine eggs per fruit. Seventy‐five per cent of the eggs were laid on the basal half of the fruit. There was no evidence of egg parasitism, but Apanteles sp. was bred from one larva. Egg mortality was negligible, but larval mortality (on cv. Wyedale) was high (68 per cent), caused partly by the failure of first larvae to establish themselves in the fruit. Once established, competition between larvae resulted in further mortality. Three sprays of azinphos‐methyl gave 100 per cent control of larvae.
