Toxicity of purified proteins and the HD-1 strain from Bacillus thuringiensis against lesser cornstalk borer (Lepidoptera: Pyralidae)
Journal of Economic Entomology 88 (3), 606-609
Abstract: Toxicity of CryIA(a), CryIA(b), CrylA(c), CryIC, and CryIIA proteins, and the HD-1 Strain of Bacillus thuringiensis was determined against neonate lesser cornstalk borer, Elasmopalpus lignosellus (Zeller), in diet incorporation bioassays. CryIIA was the most toxic of the individual proteins with an LC₅₀ (micrograms protein per gram diet) of 1.94. The LC₅₀ (micrograms protein per gram diet) for the HD-1 strain that contains all of the above mentioned proteins except CryIC was 5.46. The.toxicity of CryIIA and the HD-1 strain suggests that these compounds could be used to efficaciously control E. lignosellus in peanut fields either in typical ground applications, or in the case of CryIIA, be overexpressed in other organisms such as plants or plant-colonizing bacteria.
