The development of \kur{Spodoptera littoralis} (Boisduval) on the geneticaly modified potatoe expressing bacterial toxin Cry3Aa
 SVOBODOVÁ, Zdeňka
Spodoptera littoralis (Boisd.) larvae were fed potato leaves of the variety Newleaf Superior (NLS) that expresses Bacillus thuringiensis toxin Cry3Aa and is therefore resistant to the Colorado potato beetle, Leptinotarsa decemlineata (Say). The leaf content of Cry3Aa was determined by ELISA. Control larvae received leaves of the nearly isogenic but nontransgenic potato variety Superior. The developmental rate, mortality, weight of prepupa or pupa, female fecundity, and the egg hatchability of S. littoralis were independent of the potato type. The results suggest that Cry 3Aa toxin in the potatoe leaves has no negative effect on the development of caterpillars that consume them.
