Standard ‘Golden Delicious’ and ‘Stayman’ apple trees were sampled to determine spatial patterns of tufted apple bud moth,Platynota idaeusalis(Walker). Trees were divided into upper and lower levels vertically, and directionally into areas of the tree facing the row alleyway (BROW) and areas of the tree facing the tree row (WROW). In 1982 in unsprayed trees, significantly more summer-brood egg masses were deposited in the upper areas. Significantly more fall-brood egg masses were deposited in the upper and BROW areas. In 1983, low numbers of summer- and fall-brood egg masses were found, and there were no differences between levels or between row directions. Both broods of larvae were located more in the lower than upper levels. In sprayed trees, more larvae were found in the WROW areas, but in unsprayed trees there was no difference between row directions. Calculated sample sizes were large because of low proportions of infested spurs.
