1. The active ingredient in Bti products is a crystalline protein protoxin produced by Bacillus thuringiensis subspecies israelensis ______.
Isn't this a bacteria with endospores? I don't understand which one, I've seen different answers on Chegg.
2. Nolo Bait®, which contains spores of the obligate intracellular fungus Nosema locustae, has been licensed by the EPA as a control measure for grasshoppers. Nolo Bait is also called “Grasshopper Spore.” N. locustae spores and bacterial spores are similar in all of the following ways EXCEPT:

1. Active ingradient of Bti is found in endospore and us made up of parasporal coat of six proteins Cry4Aa, Cry4Ba, Cry11Aa, Cyt1Aa, Cry10Aa, Cry2Ba. Toxin from Bti may be used to control mosquitoes.Option B is correct.
Nolo Bait® is used to control pests and are Spores of naturally occuring Nosema locustae and spores. They causes contagious disease in grasshopper and cause death of grasshopper.
