Ovipositional behavior and post developmental biology of the potato tuberworm, Phthorimea operculella (Zeller), were compared on tubers of two hybrid Solanum berthaultii Hawkes x Solanum tuberosum L. potato clones with the processing cv. Atlantic. Multiple host choice-, no-host choice-, and paired choice tests indicated that P. operculella deposited fewer eggs on tubers of Q174-2, and NY123 than on Atlantic. Inoculation of neonates on tubers of the two hybrid potato clones resulted in reduced survivorship, shortened developmental time, and smaller prepupae, pupae, and adults than their siblings reared on Atlantic.
