Abstract:Pupae of Trichoplusia ni (Hübner) were subjected to impacts equivalent to a free fall of 6.8, 30.5, and 67 cm to their anterior, caudal, lateral, dorsal, and ventral surfaces. Pupal deaths and adult deformities increased with increasing impact forces and were greatest when pupae were struck (simulated landing) on the anterior surface. Since older pupae were significantly less susceptible to damage, processing of pupae during laboratory rearing should be delayed as long as possible to minimize damage.
