29. Derived from: Legner, E. F. & E. R. Oatman. 1965. Limitation on the pupal development of the eye-spotted bud moth in northeastern Wisconsin. J. Econ. Entomol. 58(2): 359-360.
Pupae formed in the Insectary of reared S. ocellana larvae and which died before the conspicuous development of adult structures ranged in number from 21.3 to 27.7% in all sample blocks during the 3 years. These figures compared with pupae collected from cardboard bands where in 1960, for example, 21.3% of 216 reared pupae died before full development of adult structures. The cumulative total mortality of field-collected pupae sampled before first adult emergence in July of each year ranged from 62.0 to 67.1%. Other data not wholly comparable tended to substantiate these results.
