Carbaryl is often inexpensively produced by direct reaction of methyl isocyanate with 1-naphthol. [5]C 10 H 7 OH + CH 3 NCO → C 10 H 7 OC(O)NHCH 3. Alternatively, 1-naphthol can be treated with excess phosgene to produce 1-naphthyl chloroformate, which is then converted to carbaryl by reaction with methylamine. [5]

Mormon cricket eggs hatch mostly in the spring after they are laid, although in some areas eggs may take as many as five years to hatch. Hatching begins when soil temperatures reach 4 °C (40 °F). The nymphs pass through seven instars before reaching the adult stage, typically taking 60 to 90 days.
These overwinter and hatch in late spring or early summer, with adults being present until September or October. There is a single generation each year. [2] Although adult rainbow grasshoppers are polyphagous and feed on many species of plant, the nymphs feed entirely on Wright's false willow (Baccharis wrightii) in Arizona
