متن کاملToxicity of Bacillus thuringiensis Spore and Crystal Protein to Resistant Diamondback Moth (Plutella xylostella).
A colony of Plutella xylostella from crucifer fields in Florida was used in mortality bioassays with HD-1 spore, CryIA(a), CryIA(b), CryIA(c), CryIB, CryIC, CryID, CryIE, or CryIIA. The data revealed high levels of field-evolved resistance to HD-1 spore and all CryIA protoxins and no resistance to CryIB, CryIC, or CryID. CryIE and CryIIA were essentially not toxic. When HD-1 spore was combined ...
